June 1922 - Assigned to Coco Solo, Panama Canal Zone, Command of USS R-21 (SS-98) from 1 July 1922 until 29 April 1924 when the USS R-21 was decommissioned. Through the spring and summer months R-21 operated out of New London and Newport. The craft of Submarine Division 1 sailed from New London 2 October 1922 for Coco Solo. R-21 served as flagship as the boats cruised via Hampton Roads and Guantanamo. After 11 days out, R-24 developed engine trouble and was temporarily taken under tow by R-21. The Cuba-bound steamer SS Bethore rendered assistance, and R-21 arrived at Coco Solo 27 October. R-21 spent the rest of her active Navy days operating out of Coco Solo and undergoing repairs at Balboa. She sailed from Coco Solo for the last time 15 February 1923 in company with a tender, Quail (AM-15), and eight other submarines. Two days later R-21’s engines malfunctioned. The disabled submarine was taken under tow by the escorting tender and pulled to Guantanamo Bay. Voyage repairs were quickly accomplished. The R-boat then resumed her northern transit, on 22 February 1923, and proceeded to the Philadelphia Navy Yard at Philadelphia, Pennsylvania...via a repair layover at the Charleston Navy Yard at Charleston, South Carolina.(McCann returned to Coco Solo, but remained administratively in Command) and R-21 sailed for Philadelphia, Pennsylvania on 22 February 1923, arriving there via Charleston, South Carolina, on 9 November 1923. R-21 was decommissioned at the Philadelphia Navy Yard on 21 June 1924, and placed in the reserve fleet at that Navy yard.

18 October 1926 - Detached from USS Chewink.


USS V-2 and USS S-46

24 November 1926 - Commanded the submarine USS S-46 (SS-157), based at Coco Solo, Panama Canal Zone. The submarine performed a schedule of local operations, from Coco Solo and from Balboa, Panama, which were interrupted only for semi-annual extended training cruises and annual fleet problems (Operational Readiness Inspections) in the Caribbean Sea and Pacific Ocean. Repairs and overhauls were performed at Balboa. In 1927, SubDiv 19 was transferred to the Battle Fleet and based at San Diego, California, with Mare Island Naval Shipyard as homeyard for its boats. S-46 departed Panama on 11 June; arrived at San Diego on 31 July 1927; then proceeded, via Mare Island attached to Pearl Harbor to participate in tactical exercises with other Battle Fleet submarines. During the latter part of August, she participated in the search for missing Dole Air Race pilots; and, at the end of the month, she headed back to San Diego for two months of local operations. In December, she returned to Mare Island for an overhaul; and, in June 1928, she resumed operations out of her home port.

1 May 1929 - Detached USS S-46

19 March 1929 - 18 July 1931 - Design Division, Bureau of Construction and Repair (now Bureau of Ships), Navy Department, Washington, DC - assigned to diving operations in connection with development of submarine escape apparatus, at Philadelphia Navy Yard, and was in charge of the development of a submarine rescue chamber.

Others assigned to this task were: Cmdr. Charles B. Momsen, Gunner's Mate Clarence Tibbals, and Lieutenant Carlton Shugg, who would later be head of Electric Boat, and an assistant Director of the Atomic Energy Commission. Shugg's future contributions would be essential in developing a nuclear reactor for submarines. McCann's additional duty in this assignment was as Liaison Officer/Engineer in the refit of Submarine 0-12, which became the 'Nautilus', and attempted the first under ice crossing of the Arctic sea, a mission which failed. (The Wilkins-Ellsworth Trans Arctic Submarine Expedition of 1931). The submarine underwent extensive modifications, and McCann directed the engineering aspects, working under Simon Lake, as the US Navy's representative to the Project. Part of his contribution was an Air Lock and integrated Diving Chamber built into what had been the forward Torpedo room of USS 0-12. Additionally the Conning Tower of 0-12 was modified to become retractable. The feat was amazing considering that the modification must remain pressure tight while submerged.

The USS S-1, with Water-tight Hangar.

The S-1 used a small aircraft housed in a pressurized hangar on the deck. When it was deemed too unwieldy, the plan was scrapped. The hangar, however, was salvaged and used to make the Momsen-McCann Diving Bell Prototype, which was a precursor to the design used to rescue the crew of the Squalus in 1939. Momsen who developed the Momsen Lung, at this time was Skipper of the S-1.


18 November 1929 - Commissioned as a Lieutenant Commander effective 6 June 1929.



Momsen-McCann Diving Bell Prototype (one of two)

Before October 1931 - Commander Momsen was detached to commence crew training using the Momsen Lung, and Lt. Comdr. McCann continued with the redesign of the Momsen-McCann Diving bell, making improvements, the result was a improved new chamber, called the McCann Submarine Rescue Chamber (a newer larger version is still in use as the "Submarine Rescue Chamber (SRC)")

McCann Submarine Rescue Chamber


The McCann Submarine Rescue Chamber is a device developed in 1929-1930, from a design co-designed by Lt. Cmdr. Allan R. McCann, Lt. Cmdr. Charles B. Momsen, Lt. Carlton Shugg, and Gunner's Mate Clarence Tibbals, which was called the Momsen-McCann Diving Bell. The Purpose of the device was to enable removal of crews from sunken Submarines. A history of several submarine sinkings since the early part of the twentieth Century led to development of the concept by Cmdr. Momsen, and he initiated the project.

Momsen had developed an interest in rescuing crews from submarines based on his history of working submarine salvage, and inability to rescue crews trapped in previous sinkings, although the trapped crews were alive when divers arrived at the sunken subs.

In addition to Momsen and McCann the primary participants in this project were:

Lieutenant Carlton Shugg, a co-designer of the submarine rescue chamber and designer of the New London Ct. submarine escape training tower, later became Deputy Director of the Atomic Energy Commission and director of (General Dymanics) Electric Boat, the company that made many of the submarines the Navy uses, including the Nuclear Submarines.

Gunner's Mate Clarence Tibbals, co-developer of the submarine escape "lung" and of the submarine rescue chamber (Note: there is an academic achievement award at West Point named after him).

Cmdr. McCann, who had been present at the only successful submarine crew recovery operation, the raising of Submarine 0-5 in 1923, off Gatun Lock of the Panama Canal, near Coco Solo, joined the project at an early date. He was like Momsen a submarine Commander, and had an engineering background. They would work together many times in their careers.

Development of escape devices for submarines were already in the works in several navies around the world, but the projects were not shared internationally. Momsen had begun by his development and self initiated testing of the Momsen Lung, a rebreathing device that allowed oxygen to be used in a rebreather bag, cleansed chemically of CO2, to allow a crewman to ascend from up to 250 feet. When the Navy found out about his independent efforts, and that a prototype had already been successfully tested, they adopted the device and assigned him to teach in its use. To this end he was deployed to tour the Submarine bases, and teach. This left Lt. Cmdr. McCann in charge of the Bell program, and the subsequent redesign and finalization of the concept.

Previously, Momsen while in operational command of Submarine S-1 was working on a project that was designed to encapsulate a seaplane on the deck of a submarine, and allow that seaplane to be launched and recovered at sea, by the submarine. The project ground to a halt when it was determined that the time required to launch and recover the plane left the submarine on the surface for far too long to be an effective use in wartime. (The Japanese went much further with this concept, developing the I-400 class of undersea carrier submarines in WWII.)

The incoming captain of S-1, wanted permission to uninstall the airtight hangar capsule, and wanted disposition instructions. Momsen sent the capsule to NY to be cut in two, and had the halves made into the prototype diving bells, the Momsen-McCann design. These prototypes were open bottomed bells, and the design was faulty for the purpose, Momsen stated in 1939, that they tended to "tip, and fill with water". Also the capacity was limited to very few people, they needed to be bigger.

It was at this point that Momsen left the Bell program.

Commander McCann, continued with a basic redesign and manufacture of a prototype device. The device was modified to double interior space, had a floor bulkhead installed with a water tight hatch, adaptive skirting to interface with the submarine deck, and a pneumatic haul down system installed. The new bell operated by use of an umbilical from the surface which provided the air for the haul down device, and breathing. Communications were also hard-wired into the bell. The Bell also had ballast tanks that could help stabilize and control ascension rates. The Navy adopted the Bell, and had twelve made, naming it the McCann Submarine Rescue Chamber, or simply SRC.

In 1930 the SRC was completed and testing began, using submarine S-4, a boat which had been raised months earlier after sinking with all hands lost. The S-4 had been reconfigured to be a 'sinkable' classroom for submarine escape. It had been initially used for the Momsen Lung training, and now that training would be supplemented with Rescue Chamber training.

Submarines were modified by adding anchor rings next to each hatch, these rings were added as attaching points for the Chamber when needed. A diver would attach haul down cables to these rings which running up to a rescue ship above, would allow the rescue chamber to be lowered exactly into position over the hatch, for a water tight seal. Water would be pumped or blown out of the skirt of the rescue chamber, and a pressure seal would be established, in addition hold down bars would 'lock' the seals so increased pressures from the submarine would not dislodge the Chamber upon hatch opening.

This gives the chamber operators a 'dry' space to transfer crew through, and allows the crew to enter the Chamber directly. The Chamber as originally designed could hold 8-9 personnel safely. This system also allows the submarine's ambient air to be exchanged directly from the surface.

The ascent phase was the opposite of the docking phase, seal the submarine hatch, unlock the skirt hold-downs, seal the floor hatch of the chamber, flood the skirt and mechanically retrieve the Chamber to the surface with the haul-down system, using the ballast tanks to achieve and maintain neutral buoyancy.

Redesigning the Nautilus (USS O-12)

1931 additional duty of engineering liaison officer on a project converting Submarine 0-12 to under-ice use, for the Sir George Hurbert Wilkins expedition to circumnavigate the north pole. The 0-12 became the Nautilus, and although the submarine's mission to the arctic failed, it became a point in the history of the submarine that would later be revisited by McCann. Wilkins 'leased' the Nautilus from the US Navy for $1.

Initial modifications were begun at the Philadelphia Navy Yard, but when that facility was unable to perform the required work the submarine was moved across the river to the Mathis Shipyard in Camden, New Jersey. Thirty-two new features were added to the boat, designed by the original builder, Simon Lake. These included a cushioned guide arm, a cushioning bowsprit 12 feet long to act as a bumper, an ice drill to provide access to the surface in case the submarine was unable to break through the ice, an emergency air intake system, and a diving chamber. The original superstructure was removed, and the conning tower and periscope were modified to be retractable. Lake also had the deck fittings enclosed within a wooden superstructure four feet wide and six feet high, inside of which he installed extra buoyancy chambers, which he considered necessary to prevent loss of stability during surfacing. On top of the superstructure Lake installed iron-shod "sledge runners" and two cleats at each end. Wilkins did not concur with all of the modifications introduced by Lake, fearing that they were more likely dangers than aids. A verbal agreement between the two men, however, gave Lake the final say.

Rechristened the Nautilus after Jules Verne's fictional vessel, the boat's record during the expedition was less then stellar. Plagued by mechanical difficulties and engine problems from the start, the crew were less than confident in their vessel's capabilities. When Captain Danenhower noticed that the diving rudders were missing on August 22, he suspected sabotage by the crew, and as a result of the damage, many of the scientific experiments had to be cancelled. After spending some additional time in the arctic, Wilkins headed back to port in Bergen, Norway, having failed in his mission. (source: http://www.worldhistoryblog.com/]

November 23, 1939 - North Adams Tribune, North Adams, Massachusetts -

Navy Gives 13 Nations plans for McCann Bell

Submarine Rescue Chamber invented by North Adams Native Made Available to other Countries as "Humanitarian Device" Germany, Russia, France and Japan among those given the Blueprints - Great Britain and Italy fail to request Data - Use as War Weapon of device which saved 33 from Squalus held Unlikely - Improvements Underway.

The "McCann Rescue Chamber" designed by Commander Allan R. McCann, United States Navy, a native of North Adams, and used effectively by the Navy in the rescue of 33 men from the sunken submarine Squalus last May, is now made available to 13 other nations, including Germany, Russia, France and Japan, as a "Humanitarian Device".

Sought Plans

Blueprints and additional data on the rescue chamber have been given to 13 nations by the Navy high Command, after a conference with the State Department at Washington. These countries obviously impressed by the tremendous success of the rescue chamber or "Bell" sent word to their Washington diplomats to to secure the Navy plans.

This country has given the plans and data of its Rescue Bell to the foreign powers solely for humanitarian purpose, one high official pointed out. "The device is a humanitarian one, that will be of invaluable service to to the whole world if properly handled", he said. American Navy officials do not regard the Rescue Chamber as an implement of war. Because of a long standing agreement all nations distribute inventions of "mercy" and the Rescue Bell is regarded as such. It has one "war use" although that possibility is quite remote.

Possible War use

With the Bell properly attached to a hatch, a nation at war could enter a "dead" submarine of an enemy, secure such things as ship's papers, and other data and bring them to the surface. However the Rescue Chamber works best when attached to a submarine lying on an even keel, and a submarine made "dead" by depth bombs in the time of war (unreadable - would?) be unsuitable for access by a Rescue Chamber.

In addition to Germany, Russia, France and Japan, Denmark, The Netherlands, Norway, Sweden, Jugoslavia, Argentina, Brazil, and Peru have been given the mechanical instructions for the construction of the rescue chambers. Poland, which asked for the plans a short time before Germany invaded that country, has also been handed a set of the plans, but these are probably still in Washington at the Polish Embassy.

Two nations which have many submarines - Italy and Great Britain - have not asked for the rescue device and plans. Great Britain has had several similar devices of its own, and is now working on a new invention which she thinks will be of greater service to her because of the construction of British submarines. Italy also, it is understood at Washington has a "rescue device" which its engineers have completed after many years of work.

While the McCann "Bell" represents the efforts of many men, it was designed by Commander McCann and it was mainly through his efforts that "Bell" reached the high point of efficiency that it did. He was on-hand last May when the bell went to the bottom at 40 fathoms, and rescued the men of the Squalus, and he was also inside it the night it dangled in mid ocean with a broken cable and the nine men inside were faced with death if a single thing more went wrong (transcriber note: McCann wasn't in the Bell, although he was cited for his actions in saving the Bell and its occupants when the cable failed). He stayed on the scene off Portsmouth for much of the summer leaving for Washington after the "bell" had no further use. He and the Navy are now perfecting the device so that it will render greater service.

Works like a Submarine



The "Bell" which costs $10,000 to build, weighs about 18,000 pounds and goes down to a submarine from a salvage ship on a cable. It is really a baby submarine except its functions are supplied from the outside.

Commander McCann is a graduate of Drury High School, Mrs. McCann is the former Katheryne Gallup, daughter of ex-Senator Harvey A. Gallup of this city.

May 1941 - Commander, Submarine Squadron 6, Pacific Fleet, Pearl Harbor, Hawaii. In this position during the Japanese attack on Pearl Harbor, December 7, 1941. Divers from the escape training tank and the submarine rescue vessel Widgeon rushed to assist in the rescue of men trapped in damaged ships.



December 7, 1941, Pearl Harbor, Territory of Hawaii

Pearl Harbor, Narrative of McCann in the battle:

Silent Victory, The U S Submarine War Against Japan, Page 99


The Submarine Tender USS Widgeon dockside during the attack on Pearl Harbor, Dec. 7, 1941. The McCann Submarine Rescue Chamber is on deck. This was Dock 1010 at the submarine base. Widgeon and Pelias were docked here with hthree of teh four subs in the harbor at the time of the attack. Captain McCann was abord Pelias which had just arrived as a new Tender less than two weeks previously, and was under-going initial equipping.

On the tender Pelias, moored in a backwater at the sub base, Al McCann commanding Submarine Squadron 6, was in his stateroom, in his pajamas performing Gene Tunney exercises when the alert came. He raced to the bridge in his pajamas. What he saw he later said "turned my stomach upside down". It was "Unbelievable ... shabby ... absurd" Battleship Row - California, Oklahoma, Maryland, West Virginia, Tennessee, Arizona and Nevada - was under severe air attack. The noise was deafening. There was smoke and flame all over the harbor.

Pelias was not yet fitted with her full complement of anti-aircraft weapons. McCann did not fire those he had, lest his gunners hit friendly ships, but watched in disbelief as as the bulk of the Pacific Fleet crumpled under the weight of the attack. For a while he considered getting under way and standing out of the harbor, but his path was blocked by flaming and exploding ships. When a wave of torpedo planes came over McCann was certain they were headed for Pelias, but they over flew the tender, and and attacked Hickam Field. (Pelias having only arrived November 25, was not on the Japanese target list, and only one crewman was injured: He lost his footing and fell off the gangplank while craning for a better look at the holocaust.)

That morning there were four submarines in Pearl Harbor. In addition to Wilkin's Narwhal, and Raine's old Dolphin, there was one older V boat, Cachelot, and the new Tambor-class Tautog. just returned from a long patrol off Midway. Narwhal, Dolphin and Tautog were moored at the sub base finger piers (1010 docks). Cachelot was in the Navy yard undergoing overhaul.

When the first Japanese planes appeared, the crews on all four boats ran to battle stations, setting up .30 and .50 caliber machine guns. When a Japanese plane came over Tautog, the duty officer, William Brnard 'Barney' Sieglaff, coolly directed enlisted gunners manning a .50 caliber machine gun. The tracers climbed upward into the fuselage, and the plane burst into flame, and crashed into the water 50 yards off the sub base piers. Tautog was the first U S Submarine to destroy anything Japanese.

At the navy yard, gun crews on Cachelot hammered away at Japanese planes with machine guns but got no positive hits. During the battle a Japanese plane headed for larger targets strafed the boat, hitting Seaman Second Class G. A. Myers in the right lung. Myers was rushed to the Sub base dispensary where, in time, he recovered. Myers was the first submarine force casualty of World War II and the only submarine casualty of Pearl Harbor.

(Squadron 6 was in two divisions (Division 61 - Tambor, Triton, Thresher, Trout, Tautog, and Tuna, all Tambor-class)(Division 62 - Grenadier, Gar, Gudgeon, Grayling, Grampus and Grayback also Tambor-class, only Gudgeon and Tautog were in Hawaii, Gudgeon was at sea.) Most of the Tambor-class boats were still stateside.)

After the attack on Pearl Harbor, The Philippines and the Aleutian Islands in early December 1941, the Pacific Submarine force, and the 3 Aircraft Carriers, became the primary Pacific US Navy operational vessels. The destruction in Hawaii was a long time in recovery, unfortunately the Submatrine's primary weapon the Mk. XIV Torpedo was a unacknowledged failure.

Following numerous Mark XIV torpedo failures early in World War II, RADM English worked with RADM McCann in leading successful torpedo testing and improvements in torpedo construction. Four issues were involved in the failures, weight of the warhead was greater than "test" warheads used in design validation, making the torpedoes run in nose down trim; The depth sensor was in a location where increased speed and water flow caused the sensor to 'think' it was shallower than it was, sending a signal to dive deeper; direct impact at high speeds caused the warheads to crumple the firing pin path, causing the pin to malfunction by not reaching the detonator, or by missing it; the Magnetic proximty device didn't work at the equator, or in southern hemisphere. MCCann developed solutions, moving the sensor to a neutral flow area; installing an electrical mercury switch to fire the detonator cap, and disabling the magnetic proximity fuse. The Torpedo's designers also came up with solutions, but AFTER McCann's solutions were implemented in the field.

January 1943 - additional duty in temporary command of Task Force 51, The Joint Expeditionary Task Force,(CTF 51, Miscellaneous Task Groups) and Senior Representative of Commander Submarines Southwest Pacific, to General MacArthur. The objective of TF-51 during this period was the taking of New Guinea.(Operations in the southwest Pacific)

January 2, 1943 - Allies take Buna in New Guinea.
January 22, 1943 - Allies defeat Japanese at Sanananda on New Guinea.

April 1943 - Commander, Submarine Squadron 7, Atlantic Fleet. Naval Historical Center records show Submarine Squadron SEVEN was first established during the Second World War, organized with two submarine divisions (COMSUBDIVs 71 and 72), whose mission was to conduct anti-submarine warfare (ASW) training. The command was homeported in Bermuda during the latter part of 1942 and consisted mostly of older R- and S- boats. In April 1943, the Operational Training Command, Atlantic Fleet was established with Rear Admiral D. B. Berry in charge, Squadron SEVEN was placed under Allan R. McCann who established the squadron. Operational control of Submarine Squadron Seven was shifted from the Commandant Naval Operating Base, Bermuda, to Commander Operational Training Command. Late in 1943 (September) two Free French submarines were made available for the Training Command under United States supervision. Five more were added in 1944. After the invasion of Sicily and the landing at Anzio in January 1944, five Italian submarines came across the Atlantic in February 1944 and were assigned to ASW Training Command. These foreign submarines were assigned by COMSUBLANT to Submarine Squadron SEVEN. The French and Italian submarines were excellent for training purposes due to their heavy hull construction and they made good substitutes for the newly commissioned U.S. Navy submarines rerouted to the Pacific for combat duty. With the curtailment of the escort program, the activity at Bermuda was no longer needed and was transferred to Guantanamo Bay, Cuba. Following cessation of hostilities in the Pacific, Submarine Squadron SEVEN was disestablished in 1945.

(Source: The Dictionary of American Naval Fighting Ships published by the Naval Historical Center) On 19 June, in an engagement known as the Battle of the Philippine Sea, USS Iowa, as part of the battle line of Fast Carrier Task Force 58, helped repel four massive air raids launched by the Japanese Middle Fleet. This resulted in the almost complete destruction of Japanese carrier-based aircraft. USS Iowa then joined in the pursuit of the fleeing enemy fleet, shooting down one torpedo plane and assisting in splashing another.

Throughout July, USS Iowa remained off the Marianas supporting air strikes on the Palaus and landings on Guam. After a month's rest, Iowa sortied from Eniwetok as part of the 3d Fleet, and helped support the landings on Peleliu, 17 September. She then protected the carriers during air strikes against the Central Philippines to neutralize enemy air power for the long awaited invasion of the Philippines. On 10 October, Iowa arrived off Okinawa for a series of air strikes on the Ryukyus and Formosa. She then supported air strikes against Luzon, 18 October and continued this vital duty during General MacArthur's landing on Leyte 20 October.

HOLD FOR RELEASE Afternoon NEWSPAPERS AUGUST 14, 1944 23 OFFICERS AND ENLISTED MEN DECORATED AND COMMENDED The Secretary of the Navy has authorized the following awards:

LEGION OF MERIT


Allan R. McCann

Captain Allan Rockwell McCann, U. S. Navy, 47, a native of North Adams, Massachusetts, whose wife Mrs. Katheryne F. G. McCann, is now living at 3709 Yuma Street, Northwest, Washington, 31 D.C. was awarded the Legion of Merit "For exceptionally meritorious conduct in the performance of outstanding services to the Government of the United States as Commander of a Submarine Squadron, Senior Representative of Commander Submarines Southwest Pacific, and as Temporary Commander of a Task Force and of Submarines Southwest Pacific Force from February 10 to March 7, 1943. Demonstrating exceptional ability and untiring devotion to duty as Squadron Commander, Captain McCann inspired the officers and men under his command attached to the successful completion of dangerous and vital missions. As Senior Officer, he relieved the Task Force Commander of many details and assisted in the expeditious establishment and efficient operations of units. His brilliant leadership and proficient execution of many difficult tasks were reflected in the splendid material condition of all units of this task force and the excellent morale of his men, resulting in a tremendous toll in enemy shipping.'

August 1944 - After a month's rest, Iowa sortied from Eniwetok as part of the 3d Fleet, and helped support the landings on Peleliu, 17 September. She then protected the carriers during air strikes against the Central Philippines to neutralize enemy air power for the long awaited invasion of the Philippines. In a last ditch attempt to halt the United States campaign to recapture the Philippines, the Japanese Navy struck back with a three pronged attack aimed at the destruction of American amphibious forces in Leyte Gulf. Iowa accompanied TF-38 during attacks against the Japanese Central Force as it steamed through the Sibuyan Sea toward San Bernardino Strait. The reported results of these attacks and the apparent retreat of the Japanese Central Force led Admiral Halsey to believe that this force had been ruined as an effective fighting group. Iowa, with Task Force 38 steamed after the Japanese Northern Force off Cape Engano, Luzon.

1 October 44 - USS Argonaut christened by Mrs. McCann

10 October 1944 - Iowa arrived off Okinawa for a series of air strikes on the Ryukyus and Formosa. She then supported air strikes against Luzon, 18 October and continued this vital duty during General MacArthur's landing on Leyte 20 October.

20-25 October 1944 - The Battle off Samar - USS Iowa commanded by AR McCann. (McArthur arrived back in the Philippines on October 20, 1944.)


The US Third Fleet in the Leyte Gulf.

25 October 1944 - Japanese Central Force was attacking a group of American escort carriers off Samar. This threat to the American beachheads forced Iowa to reverse course and steam to support the vulnerable "baby carriers." However, the valiant fight put up by the escort carriers and their screen had already caused the Japanese to retire and Iowa was denied a surface action. Following the Battle for Leyte Gulf, Iowa remained in the waters off the Philippines screening carriers during strikes against Luzon and Formosa.

The following is an excerpt from the:

THIRD AND FINAL REPORT TO THE SECRETARY OF THE NAVY
Covering the period 1 March 1945 to 1 October 1945
by Fleet Admiral Ernest J. King,
Commander in Chief, United States Fleet, and Chief of Naval Operations
(Issued 8 December 1945)

ATLANTIC OPERATIONS

The operations of the United States Navy in the Atlantic and Mediterranean Theaters culminated in the victory of the Allied nations in Europe. The success of the joint antisubmarine campaign and the tremendous achievements in shipbuilding were essential preludes to the landings in Normandy and southern France and the great land offensive, which in three months carried the Allied Expeditionary Forces to the German frontier and brought total victory on German soil six months later. This victory was possible because ships were available and their protection by the Navy effective.

ANTISUBMARINE OPERATIONS

In the antisubmarine campaign our Atlantic Fleet had responsibility for Atlantic areas under United States operational command, and the British Admiralty was responsible for North Atlantic and European operations in which United States naval task forces participated. In the British control areas Commander U.S. Naval Forces in Europe assured proper liaison between the Admiralty and the Tenth Fleet organization in my Headquarters, which was responsible for convoy and routing of United States shipping and the development of plans, weapons, and tactics to be employed in antisubmarine operations.

In the final month of the European war, German submarines made a last determined effort, in great strength, to reach the eastern coast of the United States. That attempt was thwarted by a powerful task force of the U.S. Atlantic Fleet, which, during an engagement lasting several days, destroyed five U-Boats. The United States Navy's final successful action against German submarines occurred on 6 May, only two days before V-E day, when a U-boat was sunk off Block Island by the destroyer escort ATHERTON with the frigate MOBERLY assisting. The development of new techniques, the intensive training of antisubmarine crews, and the persistence with which the U-Boats were hunted offensively all played vital parts in the surrender campaign. German submarines began to surface and surrender shortly after V-E day, and U.S. Atlantic Fleet escort vessels brought several of them to the United States east coast ports.

A review of antisubmarine and convoy operations since 1939 illustrates clearly these major naval contributions to victory in Europe. The summarized statistics on the Battle of the Atlantic are as follows:

German Submarines Sunk # Allied Submarines Sunk (x1000 tons) New Construction
(x1000 tons)
Net Gains(+)
or Losses(-)
Year U. S. BRITISH TOTAL

Totals 782 23,351 34,622 7,863 42,485 +19,134

From the foregoing statistical summary the chief features of the Battle of the Atlantic are clear:

(a) Until the closing months of 1942 the German submarines were continuing to reduce the available total of Allied tonnage;

(b) Antisubmarine operations resulted in the sinking of an average of 12 German submarines per month after 1 January 1943, or a total of 480 in the two years 1943-44;

(c) American shipyards alone produced an average of a million tons per month of new merchant ships after 1 January 1943, or a total of 24,000,000 tons in two years.

In the 12 months from 1 June 1944, 135 convoys arrived in United Kingdom ports from overseas with a total of 7157 merchant ships totaling more than 50,000,000 gross tonnage. The escort of this shipping and the provision of trained naval armed guard crews aboard the merchant vessels were among the primary tasks performed by the United States Navy in the prosecution of the war in Europe. The Navy's antisubmarine campaign with the British-United States integrated convoy system was in great part responsible for the vital shipping necessary for the Allied land offensive which broke into the Fortress of Europe in 1944 and overwhelmed the Germans ashore in 1945.

TENTH FLEET

On 15 June 1945 the Tenth Fleet was dissolved. This effective organization was established 20 May 1943 under my direct command, with Headquarters in the Navy Department, to exercise unity of control over United States antisubmarine operations in that part of the Atlantic Ocean under United States strategic control. The first Chief of Staff of the Tenth Fleet was Rear Admiral Francis S. Low, who was relieved in January 1945 by Rear Admiral A. R. McCann.

To the Tenth Fleet were assigned the following tasks:

  (a) Destruction of enemy submarines.

  (b) Protection of Allied shipping in the Eastern, Gulf, and Caribbean Sea Frontiers.

  (c) Support of other antisubmarine forces of our own and of the other Allied nations operating in the Atlantic areas.

  (d) Exercise of control of convoys and shipping that were United States responsibilities.

  (e) Correlation of United States antisubmarine training and materiel development.

To accomplish these tasks the Tenth Fleet was organized into four principal divisions: Operations; Antisubmarine Measures (materiel, training, analysis and statistics, and operational research); Convoy and Routing; and a Scientific Council composed of distinguished civilian scientists.

The Tenth was a fleet without a ship. However, this highly specialized command coordinated and directed our naval forces in the Battle of the Atlantic, making available the latest intelligence to the Commander in Chief, U.S. Atlantic Fleet and attached to other fleet and sea frontier commanders who directed the actual operations at sea, and supplying antisubmarine training and operating procedures to our forces afloat. The Tenth Fleet correlated the antisubmarine developments of the various technical bureaus of the Navy Department and the fleet training schools concerned with antisubmarine activities. In addition, it worked closely with the General Staff of the United States Army and with the British Admiralty and Canadian Naval Headquarters to avoid duplication and confusion, and attached to insure that maximum effort would be directed against the German underseas fleet. The effective work of the Tenth Fleet contributed outstandingly to the success of the United States naval operations in the Battle of the Atlantic.

**** END EXCERPTED TEXT OF FLEET ADMIRAL KING's 3rd REPORT to SECNAV

At the time of inception, Tenth Fleet chief-of-staff was Rear Admiral Francis S. Lowe; by April 1945, he had been replaced by Rear Admiral Allan R. McCann inventor of the McCann diving bell used to rescue submariners trapped in sunken boats. [Morison, Samuel Eliot, The Atlantic Battle Won, History of United States Naval Operations in World War II, Volume X. (Boston: Little, Brown and Co., 1956), pp 21-26, 345.]

June 1945 - Staff of the Commander in Chief, Atlantic Fleet,

NAVY DEPARTMENT JUNE 15, 1945 TENTH FLEET DISSOLVED The Tenth Fleet, organized in 1943 to direct the U.S. Navy's war against the U-boat in the Atlantic from Iceland attached to Cape Horn, has been dissolved the Navy Department announced today.

Liquidation of an entire fleet organization in time of war is unique.

It followed the winning by the Tenth Fleet, with cooperation with the British and Canadians, of a great strategic victory in the Atlantic, breaking the back of Germany's desperate effort to stave off complete defeat through the U-boat campaign. Throughout its career the Tenth Fleet was under immediate direction of Fleet Admiral Ernest E. King, U.S.N., Commander in Chief, U.S. Fleet, and Chief of Naval Operations, who guided the anti-submarine operations in addition to his other duties. During the critical months of the Atlantic war in 1943, Rear Admiral Francis S. Low, U.S.N., Assistant Chief of Staff (Anti-Submarine), U.S. Fleet, served as Chief of Staff, Tenth Fleet. He was succeeded, in January, 1945 by Rear Admiral A. R. McCann, U.S.N.

It was in February 1943 that Adolf Hitler elevated his chief of U-boat warfare, Karl Doenitz, to rank of Grand Admiral and Commander in Chief of the German Navy. It was soon apparent that Doenitz planned to use his undersea weapon with determination. In Washington, May 20, 1943, the Tenth Fleet was organized to exercise unity of control over the U.S. Navy's war against the U-boat in the Atlantic. Rear Admiral Low, with a background of submarine and anti-submarine duty in World War I and subsequent extensive submarine duty as well as service in surface ships, was assigned to supervise the fight. The Tenth was a fleet without a ship. However, this highly specialized command could, and frequently did, call upon the surface and air forces of the Atlantic Fleet and Sea Frontier Forces to carry out offensive strikes against enemy U-boats. The very existence of the Tenth Fleet was not revealed until it had been in full operation for more than four months.

The Tenth Fleet was directed to destroy enemy submarines, protect Allied shipping in the U.S. Sea Frontiers, support Allied anti-submarine forces operating in the Atlantic areas, control convoys and shipping that were U.S. responsibilities and attached to correlate U.S. anti-submarine research and personnel instruction.

To accomplish its assignment the Tenth Fleet was formed into four principal divisions: Operations; Anti-Submarine Measures (materiel, training, analysis and statistics and operational research); Convoy and Routing; and a Scientific council of civilian scientists.

Through this specialized organization Tenth Fleet headquarters made instantly available latest intelligence information, anti-submarine development and training and operating procedures to Admiral Royal F. Ingersoll, U.S.N., Commander in Chief, Atlantic Fleet, and other Fleet and sea frontier Commanders who directed the actual operations at sea.

18 July 1945 - 8 August 1945 - President Truman departs for Potsdam. Assigned as Commander, Task Force 68, USS Philadelphia (CL-41) during the Presidential trip to Berlin. This was the Potsdam Meeting with President Truman, British Prime Minister Winston Churchill and Soviet Premier Joseph Stalin, to decide how to divide the lands held by Germany.



6 August 1945 - Admiral McCann personally informed President Truman of the successful bombing of Hiroshima in Japan.

7 August 1945 - Commended by President Harry S. Truman

I-400

4 June 1946 - The Japanese I-400 was a Submersible Aircraft Carrier, and the largest Submarine ever built. I-400 is a target ship in the Pacific off Pearl Harbor for tests of the Mark 10-3 exploder. At 1210 hrs. (12:10 PM), she sinks by the stern at 21-13N, 158-07W after being hit by three Mark 18-2 electric torpedoes fired by Cdr D. B. Bell's new USS TRUMPETFISH (SS-425). ComSubPac, Rear Admiral Allan R. McCann (former CO of IOWA (BB-61) is embarked on the TRUMPETFISH and witnesses the I-400's sinking.


USS Nereus

15 Jul 1947 - Submarine Tender USS Nereus was assigned to Task Group 17.3. On 28 June 1947 she got underway for Operation 'Blue Nose', an Arctic familiarization cruise, with the submarine tender USS Nereus (AS-17) and submarines USS Boarfish (SS-327) and USS Cabezon (SS-334). On 15 July she left for the Aleutian Islands where Rear Admiral Alan R. McCann, Commander Submarine Force Pacific came aboard at Adak Island. The group was underway again 25 July, this time for the Pribiloff Islands. During this transit Army Air Force planes based at Adak took part in the antisubmarine training. On 30 July the group passed through the Bering Strait and crossed the Arctic Circle. Following along the International Date Line, the ships of Operation "Blue Nose" sighted pack ice on the morning of 1 August 1947. After reaching 72 degrees 15' north latitude, the ships continued independently along the ice pack to determine its shape. This cruise was entirely novel for a submarine tender. Admiral McCann commanded the operation and accompanied the submarine USS Boarfish on the first under-ice voyage of a US Submarine, transiting about 17 miles under the Ice-pack. He also with several crewmembers, manned a dory and explored the pack ice.

Admiral McCann retired to Winter Park, Florida, just north of Orlando. he is listed there in the 1950-3 "Who's Who in America" and in a 1951 North Adams Tribune article, and again in 1960.

ORLANDO SUN HERALD. MARCH 9, 1978 MCCANN Vice Admiral Allan R. McCann, 81, U.S. Navy, Ret, died Wednesday, Feb. 22 at Balboa Naval Hospital in San Diego, Ca.

Admiral and Mrs. McCann resided in Winter Park for many years after his retirement. McCann had a long and distinguished career following his graduation from the U.S. Naval Academy in 1917. He was closely associated with the submarine force from the time he commanded the K-6 at age 23, until being assigned as Commander Submarine Force Pacific Fleet in 1946.

Admiral McCann was, best known for his work involving submarine safety and rescue. As a young officer, he devised a system for locating and rescuing personnel from a sunken submarine. The rescue unit called 'McCann Rescue Chamber' was installed in all U.S. Submarines. [sic - The Chamber was operated from a salvage vessel] McCann achieved national prominence in 1939 when the submarine Squalus sank off Portsmouth, N. H. trapping the entire crew, more than 240 feet below the surface. McCann, who directed operations, utilized the Rescue Chamber to remove 33 survivors.

During World War II, he had diverse assignments. He commanded a Squadron of submarines operating in the Pacific, directed operations against German U-boats in the Atlantic, and then returned to the Pacific in command of the battleship, Iowa. Following the war, he transported President Harry S. Truman to Potsdam for the historic peace conference.

Surviving are his wife, Katheryn, Laguna Hills, Ca.; daughters, Mrs. Miles Finley, Solana Beach, Ca., Mrs. David Maher, Camarillo, Ca., and Mrs. A.C. Hays, San Antonio, Tex.; nine grandchildren, and six great grandchildren.
