Radar-equipped bomber devices for maritime reconnaissance/antisubmarine patrol Mitsubishi G3M3 (Model 23) "Nell": This bomber for long range capacity, in 1943, was used as a Maritime reconnaissance/Radar aircraft for long range missions and some electronic warfare work in the seas. Mitsubishi G4M1 (Model 11/12) "Betty": From 1942, the G4M of this model was also used for the same purpose as the G3M bomber, for maritime long range capacities with sea radar and electronic warfare equipment. Nakajima B5N2 "Kate"/Nakajima B6N1-2 Tenzan "Jill": In 1944, some torpedo bombers of mentioned types used with antisubmarine, radar detection (with finding radar equipment) and similar purposes in maritime short or medium range missions from carriers or land bases. Aichi E13A1b "Jake" Mark 11B: like model 11A, added Air-Surface radar and other night conversion with radar (E13A1b-S). Kawanishi H6K2,4 and 5 "Mavis" Marks 11,22 and 23: More powerful engines, for ultra long range missions, long range sea radio equipment and air-surface finding radar added. Kawanishi H8K2 "Emily" Mark 12: more potent engines for ultra-long range maritime recon missions, major heavy armament; also long range sea radio equipment and air-surface search radar added Kawanishi E7K2 "Alf" Mark 2: short range hydroplane, was installing magnetic detection equipment and finding surface radar for short range patrol and antisubmarine missions Kyushu Q3W1 Nankai (South Sea): two place version of training aircraft Kyūshū K11W1 Shiragiku, for anti-submarine patrol - was equipped with sea-surface finding antisubmarine sonar (one prototype) Kyūshū Q1W1 Tokai "Lorna": Anti-submarine patrol aircraft. Was equipped with sea-surface radar and antisubmarine equipment for escorted convoys in the East China Sea, the Yellow Sea and the Sea of Japan during short times in 1944-45. Mitsubishi Q2M Taiyō: Advanced Antisubmarine patrol design, derived from Mitsubishi Ki-67 Hiryū "Peggy" Bomber. Was equipped with magnetic antisubmarine search device, air-surface radar and electronic warfare equipment.
