In early-December 1941, Force Z arrived in Singapore to reinforce the British position in the Far East and deter Japanese aggression. Commanded by Admiral Tom Phillips, it consisted of two capital ships (HMS Prince of Wales and Repulse) and four destroyers.
Small and unbalanced, Force Z failed to deter the invasion of British Malaya on 8th Dec. With no air support and limited understanding of Japanese bomber range, Phillips decided to launch a fast strike on the Kota Bharu landing site in northeast Malaya. On 9th Dec, Force Z was spotted by Japanese planes, forcing Phillips to discard his plan and head back south. But after receiving a report of a Japanese landing at Kuantan – hundreds of miles away from the nearest IJN airbase – Phillips moved to investigate.
By the time Force Z arrived off Kuantan the next day, a strike force of 85 land-based bombers from Genzan, Kanoya, and Mihoro Air Groups had been deployed to find Force Z. Once the capital ships were spotted by a scout plane, the attacks began at 11.15 hrs.
Repulse was the first target for the bombers. Completed in 1916, the battlecruiser was fast but lacked strong armour. She carried a main armament of six 15 in. guns and nine 4 in. Mk IX guns in triple mounts. By 1941 her anti-aircraft (AA) defences had been expanded to include six 4 in. Mk V guns in single mounts, twenty-four 2-pdr ‘pom-poms’ in eight-barrel mounts, eight single 20mm Oerlikon mounts, and sixteen 0.5 in. machine guns in four-barrel mounts. These were fairly effective against level bombers, damaging five out of eight planes from the first wave.
Against further waves, Repulse used her speed to avoid several torpedoes and suffered only minor damage from high-level bombs. But the final blow came at 12.20 hrs. Through intense AA fire, twenty G4M ‘Bettys’ from Kanoya Air Group overwhelmed Repulse and scored five torpedo hits. One of them is shown here, striking amidships on the port side. These strikes caused a rapid list to port before the battlecruiser finally sank at 12.33 hrs – the first time a capital ship was defeated solely by air power on open waters. The battleship Prince of Wales met the same fate at 13.20 hrs.
Force Z’s destroyers rescued 796 survivors from Repulse out of a total crew of 1,309. For the loss of three planes and 21 airmen, the Japanese had severely weakened British efforts to hold Malaya and Singapore.
