Radar-equipped bomber devices for maritime reconnaissance/antisubmarine patrol
Mitsubishi G3M3 "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 "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 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.
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.
