Radar-equipped bomber devices for maritime reconnaissance/antisubmarine patrol

[edit]
  • 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.
