The Triton-class was the first sub-assembly of the British T-class submarines . In the literature, the term Triton class is sometimes used to describe the entire T class.
The 15 submarines were built between 1936 and 1940 and used by the Royal Navy during World War II . The last boat in the class was scrapped in 1947.
Building history and structural features
At the beginning of the 1930s, the Royal Navy decided to build a new class of ocean-going submarines. The planned class of ships was intended to replace the unreliable submarines of the O , P and R classes .
The Admiralty required a sea endurance of at least 42 days and a strong armament. As a result of the London Fleet Conference of 1930 , Great Britain had 16,500 ts of tonnage available for new submarines. In order to be able to build as many boats as possible with the permitted tonnage, the boats were designed smaller than their predecessors.
The construction of a prototype was commissioned with the 1935 naval construction program at Vickers-Armstrong. The HMS Triton was launched the following year, launched in 1937 and entered service on November 9, 1938. The new building was superior to its predecessor in many respects. The surface speed was lower than that of the older British submarines due to the smaller diesel engines due to the tonnage.
By November 1938, 14 more submarines had been laid down. The Royal Navy put the last unit into service in January 1941.
In the test phase, the HMS Thetis sank on June 1, 1939 during a test drive in the River Mersey . The accident claimed 99 lives. The wreck was later lifted, repaired, and put into service in 1940 under the name HMS Thunderbolt . The name Thetis was no longer given to the T-Class.
Comparison of prototypes and series production
The series production was a little smaller than the prototype. Several submarines such as the Tigris and the Torbay were later equipped with the additional stern torpedo tube typical of the third construction lot .

Active units
When the war began, the Royal Navy only had three Triton-class units. However, new units were continuously added, so that the number increased to 10 submarines by the time the fighting in Norway took place. In 1940 four boats were lost, which could be replaced by four new ones. In 1941 there was a loss and the last influx. In the two following years two units were lost. At the end of the war in August 1945, the Royal Navy still owned six Triton-class submarines . All remaining boats were scrapped by 1947.

Mission history
1939
Since the range of the British reconnaissance aircraft of the type Avro Anson was not enough, the few existing submarines were after the war began off the Norwegian coast to educate and to protect the British naval blockade used. Due to planning errors, the crews were not equipped with sufficient winter-proof clothing and suffered from the inhospitable conditions of the North Atlantic in the autumn and winter months.
On September 10th, during a mission 28 nautical miles south-southwest of Stavanger , a serious error occurred . The O-class boat Oxley had left its patrol area as a result of a navigation error and was approaching the Triton , which tried several times to contact the unidentified submarine but received no response. After the Oxley did not respond to a flare, the Triton attacked with two torpedoes. Only the commander and one other seaman survived the attack. Four days later, the British submarine Sturgeon attacked its sister boat Swordfish in a similar situation , but missed the target. As a result of the incidents, the Admiralty increased the distances between the patrol areas of British submarines from 4 to 16 nautical miles.
In the following months of the war, the British naval reconnaissance received modern, long-range American Lockheed Hudson reconnaissance aircraft, with which the Norwegian coast could be monitored from the air. This allowed the British submarines to be withdrawn from the Norwegian coast and used closer to the opposing coasts in the Skagerrak and the German Bight . The period up to April 1940 is also known as the seat of war due to the defensive behavior of the Anglo-French allies on the Western Front . In order not to provoke the German naval command, the submarines were also used cautiously. Torpedo attacks without warning on enemy transport ships were expressly prohibited. Merchant ships should be strictly controlled according to international price law . The British leadership feared another all -out submarine war , which had already brought the United Kingdom into serious difficulties at times during the First World War .
1940
Due to the limitations and also the small number of operational Triton boats, despite frequent patrols, the first combat success of the submarine class did not occur until March 25, 1940, when HMS Truant controlled the German cargo steamer Edmund Hugo Stinnes 4 off Jutland and then with torpedoes sunk.
On April 9, 1940, a new phase of the war began with the German company Weserübungen . In the then largest triphic operation in war history, German units occupied Denmark almost without a fight and conquered the most important ports of Norway in a few days despite resolute resistance. The British side was prepared for the attack and stationed all available submarines along the expected approach routes of the invasion fleet before the attack. On April 8th, Trident sank the tanker Stedingen . On the same day Triton attempted an unsuccessful torpedo attack against the cruisers Emden , Lützow and Blücher . On the evening of the day of the invasion, Truant managed a successful torpedo attack against the light cruiser Karlsruhe . The German warship was badly damaged and sunk three hours after the attack by the German torpedo boat Greif . The following day the Triton boats were able to record three more successes, but also suffered the first loss. While Triton sank two German transporters and an auxiliary patrol boat , Thistle was torpedoed by a German submarine. Another Triton boat was lost in April, Tarpon . The fighting in Norway, especially the Battle of Narvik , dragged on into June. In the clear waters of the North Sea, submerged submarines can be seen from the air in daylight at a depth of up to 30 m when the sea is calm. In addition, diesel-electric submarines at that time had to charge their accumulators while surfaced, and usually did so under cover of darkness. The ever shorter nights made British submarine missions off Northern Norway more difficult and, in view of the increasing local German air superiority at the beginning of the polar day ( Narvik is over 200 km north of the Arctic Circle !), Made them more and more dangerous in summer and basically impracticable in midsummer. In addition, at that time the German defense was able to decipher 30–50% of British radio traffic.
On May 10, the case of Gelb started the war in Western Europe. After Italy entered the war on June 10 and the French defeat on June 22, more and more patrols led off the French Atlantic coast and into the Mediterranean . Triton boats sank several fishing vessels and transport ships, as well as a submarine and a seaplane tender, in the Bay of Biscay by the end of the year .
In the Mediterranean, the attack area against merchant ships was initially limited to a strip of 30 nautical miles off the coasts of Italy and Libya in order to protect neutral shipping traffic. Four Italian freighters and one tanker were sunk here between September and the end of the year. In return, two more Triton boats were lost. With the poor exchange ratio of opposing and own losses, the Triton boats were in a relatively good position compared to the other British submarines in the Mediterranean. In total, British submarines sank only nine enemy ships and one submarine in the Mediterranean in 1940. Including the two Triton boats, nine British submarines were lost in the Mediterranean during the same period.
1941
In January, the HMS Torbay, the last submarine of the class, was put into service. In November a submarine was lost in the Mediterranean.
The main focus of the Triton boats shifted more and more to the Mediterranean. The bases were in Gibraltar in the west, on the besieged island of Malta in the center and in Alexandria in the east. In June the Truant , Triumph , Taku , Tetrarch and Torbay were stationed in Alexandria.
During 1941, the Triton boats sank 22 cargo ships, four tankers, six auxiliary warships, 30 sailing ships and two submarines in the Mediterranean.
The most successful unit was the newly commissioned HMS Torbay . The submarine sank three tankers, 11 sailing ships and one submarine off the Greek islands. The commander Lt. CD. Anthony Miers also committed several war crimes with the murder of prisoners of war and castaways.
A smaller part of the Triton boats continued to be used in the Bay of Biscay and off the Norwegian coast. The bases were in England, Scotland and, after the German attack on the Soviet Union on June 22, 1941, also in Poljarny in northwestern Russia . Seven freighters, a tanker, an auxiliary warship and a submarine were sunk off the Norwegian coast and in the Bay of Biscay.
1942
The Pacific War began with the Japanese attack on Pearl Harbor on December 7, 1941 and the Japanese invasion of the Malay Peninsula initiated the following day .
Due to the serious situation in the Mediterranean and the uninterrupted German submarine attacks in the Atlantic, the Royal Navy was initially only able to release limited forces for the new theater of war, which also included submarines. In February, the HMS Truant attacked the Japanese light cruiser Nagara off Bali in the Dutch East Indies , but missed the target. The submarine sank two in Malakka Street in April and another Japanese cargo ship in July.
In the entire year, only one freighter was sunk in the North Sea. An important success came in February when the Trident attacked the two German heavy cruisers Prinz Eugen and Admiral Scheer with ten torpedoes west of Kristiansund . The Prinz Eugen was hit and very badly damaged.
In the Mediterranean, the Triton boats continued to fight against the Axis supply lines for the war in North Africa . The submarines sank four freighters, four sailing ships, two tankers, three auxiliary warships and one submarine. The Axis' increasingly organized anti-submarine defense sank two Triton-class submarines in the course of the year.
1943
Until the Axis troops surrendered in North Africa in May, the Triton boats continued to fight their supply routes from Europe. After the end of the war in North Africa and the Allied landing in Sicily in July , the areas of operation of the British submarines in the Mediterranean relocated to the southern French coast in the west, which was occupied by Germany in November 1942, and the Greek islands, which were also occupied by Germany, in the east. The Triton boats sank 13 freighters, 11 sailing ships, four auxiliary warships and two trawlers. Two other boats of the class were also lost.
In January, the HMS Thunderbolt, together with the Tempest-class boat HMS Trooper and the Taciturn-class boat HMS P311, participated in the spectacular attack on the recently commissioned light cruiser Ulpio Traiano , known as Operation Principle . The T-class boats transported manned Chariot torpedoes in front of the port of Palermo , which sank the Italian warship with sticky mines.
1944-1947
The Allied victories of 1943 were followed by the Allied landings in Brittany and on the Côte d'Azur in 1944 , which decided the war in the Mediterranean. The few remaining Trident boats suffered no further losses. In 1944 they sank a few enemy ships in the Mediterranean Sea and off Norway.
In the last year of the war, several smaller Japanese units were sunk in Asia.
At the end of the war in August 1945, six Triton-class units were still in active service with the Royal Navy. All six submarines were decommissioned and scrapped by 1947.
Battle successes (selection)
The 15 Triton-class boats achieved most of their fighting successes in the Mediterranean. It is noteworthy that the British submarines stood out as submarines and sank a total of five Italian submarines.

HMS Thistle | April 10, 1940 | HMS Thistle was sunk 20 nautical miles west of Stavanger at 59 ° 0 ' N , 5 ° 0' E by the German submarine U 4 . There were no survivors. |
HMS Tarpon | April 14, 1940 | HMS Tarpon has been missing off the Norwegian coast since April 22, 1940. It may have been sunk on April 14, 1940 by the German M 6 minesweeper with depth charges. Another explanation is that she was sunk on April 10, 1940 west of Jutland at 56 ° 43 ' N , 6 ° 33' E by the German submarine trap Schiff 40 / Schürbek . The entire crew was killed. |
HMS Triad | October 15, 1940 | HMS Triad was torpedoed and sunk south of the Gulf of Taranto at 38 ° 16 ' N , 17 ° 37' E by the Italian submarine Enrico Toti . There were no survivors. |
HMS Triton | December 18, 1940 | HMS Triton goes missing in the southern Adriatic . The Triton was probably sunk by the Italian torpedo boat Clio on December 18 . Another possible explanation is that the Triton ran into an Italian sea mine in the Strait of Otranto . There were no survivors. |
HMS Tetrarch | November 2, 1941 | HMS Tetrarch left its base in Malta on October 26th for an overhaul. But she did not reach Gibraltar , where she was expected on November 2nd. She probably ran into a sea mine in the Strait of Sicily at the end of October . The entire crew was killed. |
HMS triumph | January 14, 1942 | HMS Triumph left its base in Alexandria on December 26, 1941 to land a command near Athens , which happened on December 30 and was reported by radio. There has been no news of the boat since then. Presumably the Triumph ran into a sea mine near Milos . The Royal Navy declared the submarine missing on January 14, 1942. The entire crew was killed. |
HMS talisman | September 17, 1942 | HMS Talisman left Gibraltar on September 10th. On September 15, she reported the sighting of a submarine off the Algerian coast. Since then there has been no contact with the talisman . She probably ran into a sea mine in the Strait of Sicily on September 17th. The submarine was declared missing on September 18, 1942. There were no survivors. |
HMS Tigris | March 10, 1943 | HMS Tigris left its base in Malta on February 18 to patrol southwest of Naples . She was expected in Algiers on March 10th , where she never arrived. Since then, the submarine has been counted as missing. It was probably six nautical miles south of February 27, Capri by the German U-hunter UJ-2210 sunk. Other theories suggest that the Tigris in the Gulf of Tunis was sunk by a mine hit. There were no survivors. |
HMS Thunderbolt | March 14, 1943 | HMS Thunderbolt was sunk by the Italian corvette Cigogna off San Vito lo Capo ( Sicily ) . There were no survivors. |
