XE-class submarine
1944 class of British midget submarines

The XE-class submarines were a series of twelve midget submarines that were built for the Royal Navy during 1944; four more to a slightly different design were built 1954–5 as the Stickleback class.
Design
The XE had a crew of four, one lieutenant acting as the commander, a sub-lieutenant acting as the deputy, an engineer in charge of the mechanical aspects of the sub, as well as a seaman/leading seaman. Each submarine also contained at minimum one certified diver.
Each were armed with 2 side-charges, each with 2 tons (4,400 pounds) of Amatol explosives. Each also contained up to six 20-pound limpet mines. These were to be attached targets by a diver.
They and their depot ship HMS Bonaventure arrived at Labuan in July 1945. Four of them managed to take part in operations before the war ended.
Operational history
Sabre and Foil
These operations, carried out in July 1945, were intended to cut the undersea telephone cables connecting Singapore, Saigon, Hong Kong and Tokyo. The intention was to oblige the Japanese to use radio and render themselves open to message interception.

Why this record matters
The phrase “1944 class of British midget submarines” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q16039542. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1944, 1954 and 1945.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
