A prewar British route to wire-guided torpedoes

Could Britain have developed wire-guided submarine torpedoes before the Second World War?

British work was already under way. Continuing it offers a possible prewar route that was not pursued historically.

British work on wire-guided torpedoes was already under way before the war in the chronology given here. Britain stopped that programme around 1939 to concentrate on other torpedo developments, while the Americans reached the technology in 1946. Continuing the British work offers a potential counterfactual route to earlier wire guidance. No completed prewar weapon or detailed development schedule is identified.
