EventMap Founded 1962

The Association was formed in 1962 and is non-political and non-denominational. The aim of the Association is to show friendship and goodwill towards each other. To arrange exchange visits for us and our children for a better understanding in the future. To remain loyal to our Sovereign and country at all times and to work for the ideals that World War II was fought – freedom of speech, expression and thoughts.

The I.S.A. is a world wide Association of Submariners, which includes members from Albania Argentina, Australia, Austria, Belarus, Belgium, Canada, Chile, Croatia, Czechoslovakia Estonia, France, Germany, Great Britain, Greece, Israel, India, Italy, Kazakhstan, Netherlands New Zealand, Norway, Peru,  Poland, Russia, Slovenia, Sweden, Switzerland, Turkey, the Ukraine ,and the USA.

Annually, a 3 day Congress is held, hosted by a different country each year, when Submariners and their ladies from all over the world enjoy getting together socially, meeting old friends and making new ones, dining and dancing, sightseeing etc.

The I.S.A.[GB] holds four meetings per year- in the Middle section of the UK, i.e. North, Stoke across to Norwich and South, Cardiff across to Southend. A hotel is chosen in the designated area, where we can have our meeting on the Saturday and dine together in the evening. These meetings have also become great social occasions where we meet up with old boat mates and enjoy a few drinks together. The ladies are also made most welcome – in fact, the I.S.A. encourages the ladies to take part in all their activities.

Further information about any of the above is available on request from the Secretary.

Every year a international congress is held in a host country.   

Next year it will be Croatia.

The Oberon class was a direct follow on of the Porpoise-class, with the same dimensions and external design, but updates to equipment and internal fittings, and a higher grade of steel used for fabrication of the pressure hull.

As designed for British service, the Oberon-class submarines were 241 feet (73 m) in length between perpendiculars and 295.2 feet (90.0 m) in length overall, with a beam of 26.5 feet (8.1 m), and a draught of 18 feet (5.5 m). Displacement was 1,610 tons standard, 2,030 tons full load when surfaced, and 2,410 tons full load when submerged. Propulsion machinery consisted of 2 Admiralty Standard Range 16 VMS diesel generators, and two 6,000 shaft horsepower (4,500 kW) electric motors, each driving a 7 feet (2.1 m) 3-bladed propeller at up to 400 rpm. Top speed was 17 knots (31 km/h; 20 mph) when submerged, and 12 knots (22 km/h; 14 mph) on the surface. Eight 21-inch (530 mm) diameter torpedo tubes were fitted (six facing forward, two aft), with a total payload of 24 torpedoes. The boats were fitted with Type 186 and Type 187 sonars, and an I-band surface search radar. The standard complement was 68: 6 officers, 62 sailors.  Ocelot was laid down by Chatham Dockyard on 17 November 1960, and launched on 5 May 1962. The boat was commissioned into the Royal Navy on 31 January 1964. Ocelot was the last submarine built for the Royal Navy at Chatham Dockyard, although three more Oberons; Ojibwa, Onondaga and Okanagan-were built for the Royal Canadian Navy.

Operational history

After commissioning, Ocelot was assigned to the 3rd Submarine Squadron, based at HMNB Clyde, in Faslane. During the 1960s, Ocelot took part in clandestine missions. Ocelot attended the 1977 Silver Jubilee Fleet Review off Spithead when she was part of the Submarine Flotilla.

Decommissioning and fate

HMS Ocelot was paid off in August 1991 as the conventional submarine fleet of the RN began to decline, making way for the nuclear fleet. She was sold in 1992 and preserved as a fully tourable museum in Chatham Historic Dockyard.

In November 2013 the interior of HMS Ocelot was added to Google Street View by Google Business Photos Agency, CInsideMedia Ltd.

HMS Tally-Ho was a British submarine of the third group of the T class. She was built as P317 by Vickers Armstrong, Barrow, and John Brown & Company, Clydebank, and launched on 23 December 1942. She has been the only ship of the Royal Navy to bear the name Tally-Ho, probably after Tally-ho, a hunting call.

Second World War service

While commanded by Captain Leslie W. A. Bennington, Tally-Ho served in the Far East for much of her wartime career, where she sank 13 small Japanese sailing vessels, a Japanese coaster, the Japanese water carrier Kisogawa Maru, the Japanese army cargo ships Ryuko and Daigen Maru No.6, the Japanese auxiliary submarine chaser Cha 2, and the Japanese auxiliary minelayer Ma 4. She also damaged a small Japanese motor vessel, and laid mines, one of which damaged the Japanese merchant tanker Nichiyoku Maru.

On 11 January 1944, Tally-Ho, then based out of Trincomalee, Ceylon spotted the Japanese light cruiser Kuma and destroyer Uranami on anti-submarine warfare exercises about 10 miles (16 km) northwest of Penang. Tally-Ho fired a seven-torpedo salvo at the Japanese cruiser from 1,900 yards (1,700 m), hitting her starboard aft with two torpedoes, and setting the ship on fire. Kuma sank by the stern in the vicinity of 05°26?N 99°52?E.

Tally-Ho sank the German-commanded U-boat UIT-23 (formerly the Italian submarine Giuliani), just off the western mouth of Malacca Strait on 14 February 1944.

On the night of 24 February 1944 Tally-Ho was ordered back to the Sembilan Islands, and while zig-zagging on the surface at night charging the batteries, lookouts spotted two wakes ahead. Believing there was a possibility of the two vessels being friendly (both Truculent and Tactician being in the area), Tally-Ho immediately altered course to avoid a collision with the rapidly approaching vessels. On making a challenge with the Aldis lamp the vessels responded by altering course straight towards them and dropping depth charges, leaving no doubt they were unfriendly vessels. At this point the closest ship fired a shell which passed dangerously close over Tally-Ho's conning tower before the attacker passed closely by the submarine and then turned for another attack. During this encounter Tally-Ho had been unable to dive due to the proximity of the attackers and the shallowness of the waters in the straight, in addition, diving would have presented the attacking ships with the opportunity to ram or depth charge the submarine. In the darkness Tally-Ho manoeuvred to a parallel course to the approaching attacker and the enemy vessel passed closely by the submarine, a loud hammering and tearing noise being heard as the ship passed, the vessel being identified as a Hayabusa-class torpedo boat of 600 tons. As the attacker disappeared in the murk Tally-Ho took on a list to port and assumed a marked bow-down attitude. Bennington decided that the batteries would have sufficient charge to risk diving which Tally-Ho then did. Before closing the conning tower hatch, he noticed that the submarine had taken on a 12-degree list. Once submerged, the crew took stock of the damage, and apart from smashed light bulbs and gauge dial glasses, Tally-Ho appeared to be seaworthy, and she remained submerged until 06:30 of 24 February when Bennington brought Tally-Ho to periscope depth and observed his attacker making unusual manoeuvres apparently searching for the submarine on the starboard quarter some 4 miles (6.4 km) off. Tally-Ho remained dived for the following 12 hours before surfacing after dark at 18:25. Upon surfacing it was noticed that the submarine's list had increased to 15 degrees, and it was possible to see the damage to the submarine's port ballast tanks which were all open at the top and beyond further use. With transfer of fuel and water from various tanks and moving of stores and torpedoes, the bow-down attitude was reduced to 4 degrees, and the three-day journey to Trincomalee commenced. This was uneventful apart from encountering a monsoon during the passage of the Bay of Bengal and the possibility of encountering a Japanese submarine close to home. Arriving at Trincomalee harbour on 29 February 1944, Tally-Ho missed her escort and found herself amongst Admiral James Sommerville's battle fleet at exercises. Later, upon examination in dry dock prior to repairs, the extent of the damage to Tally-Ho's port ballast tanks became apparent. The rotating screws of the torpedo boat had run the length of the tanks, chewing large holes in them, phosphor bronze fragments of the attacker's propeller blades being discovered inside. Post-war enquiries learned that their attacker's behaviour after the attack had been due to a combination of Tally-Ho's lowered port bow hydroplane having pierced the torpedo boat's hull, and the vessel's port screw having been shorn of its blades almost down to the hub.

On 29 October 1944, Tally-Ho departed Ceylon carrying an OSS-sponsored three-man Free Thai team bound for Siam. On the way, Tally-Ho tried unsuccessfully to intercept a German submarine. The journey was further delayed by a search for downed Allied airmen near the Straits of Malacca. The Free Thai team was finally landed on Ko Kradan, Trang Province, on 9 November.

Post War service

Tally-Ho survived World War II and continued in service with the Royal Navy. In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II. She was sold to Thomas W. Ward Ltd and scrapped at Briton Ferry, Wales on 10 February 1967.

HMS Dreadnought

The Royal Navy had been researching designs for nuclear propulsion plants since 1946, but this work was suspended indefinitely in October 1952[1] In 1955 the United States Navy completed USS Nautilus, the world's first nuclear-powered submarine. During subsequent exercises with the Royal Navy, Nautilus demonstrated the advantages of the nuclear submarine against British anti-submarine forces, which had developed extensive anti-submarine warfare techniques during the Second Battle of the Atlantic. The Admiralty appreciated the utility of such vessels and under the drive of the First Sea Lord, Admiral The Earl Mountbatten of Burma and the Flag Officer Submarines, Sir Wilfred Woods, plans were formed to build nuclear-powered submarines.

Although the plan was to build all-British nuclear submarines, much time would be saved by accepting US nuclear technology. The excellent relations between Admiral Mountbatten and US Navy Chief of Naval Operations Arleigh Burke, expedited obtaining that help. This was despite Rear Admiral Hyman Rickover, in charge of the American naval nuclear power program, being set against any transfer of technology; indeed, Rickover prevented Mountbatten inspecting USS Nautilus. It was not until a visit to Britain in 1956 that Rickover changed his mind and withdrew his objections.[1] Although Rickover wished to supply the third generation S3W reactor of the Skate class, Mountbatten exerted his influence and the entire machinery system for an American Skipjack-class submarine, with its fifth generation S5W reactor, was obtained.[1] This was known as the "American Sector" (see 1958 US-UK Mutual Defence Agreement). The hull and combat systems of Dreadnought were of British design and construction, although British access to the Electric Boat Company influenced the hull form and construction practices.

Dreadnought was laid down on 12 June 1959, and launched by Queen Elizabeth II on Trafalgar Day, 21 October 1960. The reactor was embarked in 1962 and Dreadnought made her first dive, in Ramsden Dock, on 10 January 1963. She commissioned on 17 April 1963.

During Dreadnought's construction, Rolls-Royce, in collaboration with the United Kingdom Atomic Energy Authority at the Admiralty Research Station, HMS Vulcan, at Dounreay, developed a completely new British nuclear propulsion system. On 31 August 1960, the UK's second nuclear-powered submarine was ordered from Vickers Armstrong and, fitted with Rolls-Royce's PWR1 nuclear plant, Valiant was the first all-British nuclear submarine.

The eleventh HMS Vanguard of the Royal Navy is the lead boat of her class of Trident ballistic missile-armed submarines. The submarine is based at Faslane, HMNB Clyde, Argyll, Scotland.

Vanguard was built at Barrow-in-Furness by Vickers Shipbuilding and Engineering Ltd (now BAE Systems Submarine Solutions), was launched on 4 March 1992, and commissioned on 14 August 1993. She has two crews, "Port" and "Starboard".

The submarine's first commanding officer was Captain David Russell.  In February 2002, Vanguard began a two-year refit at HMNB Devonport. The refit was completed in June 2004 and in October 2005, Vanguard completed her return to service trials (Demonstration and Shakedown Operations) with the firing of an unarmed Trident missile. During this refit, Vanguard was illegally boarded by a pair of anti-nuclear protestors.

On 4 February 2009, Vanguard collided with the French submarine Triomphant in the Atlantic. She returned to Faslane in Scotland, under her own power arriving on 14 February 2009.

The R-class submarines were a class of 12 small British diesel-electric submarines built for the Royal Navy during World War I, and were forerunners of the modern attack submarine, in that they were designed specifically to attack and sink enemy submarines, their battery capacity and hull shape being optimised for underwater performance.

With a submerged speed of 14 kn (26 km/h; 16 mph), the class set an underwater speed record not broken until the experimental Japanese Submarine No.71 of 1938, which was capable of more than 21 kn (39 km/h; 24 mph) submerged.

Ordered in December 1917, the R-class were designed to be faster underwater than on the surface, achieving a submerged speed of 14 kn (26 km/h; 16 mph) versus a surfaced speed of 9 knots (17 km/h). They were well-streamlined, having no external ballast tanks, casing, or deck gun, and a streamlined spindle-shaped hull of circular cross-section[2] (not reproduced until the Los Angeles-class) which tapered sharply towards the stern and allowed only for a single screw. The bulbous bow contained five sensitive hydrophones and the lightened conning tower was also well-streamlined.

Thirty-five percent of the space inside the pressure hull was occupied by machinery. A single 8-cylinder 480 hp Diesel engine was installed for surface propulsion, while high underwater speed was given by two large electric motors arranged one behind the other to drive the single propeller shaft, and powered by a 200-cell battery of the same type fitted to J-class submarines. The large battery was, however, sufficient for only about an hour at full power. In addition, the engine took a full day to charge the batteries, using half its power. Charging was therefore undertaken in harbour, using a supply of electricity from the shore or from special battery charging vessels.

Despite being designed for maximum underwater performance, the R-class submarines were extremely difficult to control submerged, especially at high speeds. Surfaced, they had poor seakeeping and were slow. Minor modifications were made to R4, the only submarine of the class to survive into the 1930s, which made it more manageable on the surface, but reduced its submerged speed to a maximum 13 kn (24 km/h; 15 mph).


The R-class were the first Royal Navy submarines to be fitted with six bow torpedo tubes, number of torpedoes being considered more important than range or size of warhead carried when attacking U-boats. The torpedo tubes were originally the smaller 18 inches (460 mm) but later changed to 21 inches (530 mm).[4] As designed, one spare torpedo was allowed for, but in operation six reloads were carried in place of the senior Ratings' accommodation. It was originally intended to fit a 4 inch gun on the foredeck, but this was dropped due to the adverse effect it would have had on submerged speed.
