Douglas A-20J Havoc
Early in the summer of 1943, the Air Materiel Command at Wright Field requested that Douglas study the possibility of installing a transparent, bomb-aimer's nose in approximately one out of ten A-20Gs. This would enable the aircraft to be used as formation leaders on bombing runs, with solid-nosed A-20Gs dropping their bombs on signal from the leader. The A-20J was the result.
For the A-20J, Douglas designed an entirely new nose, which consisted of a frameless, molded Plexiglas canopy. This nose added seven inches to the aircraft's length, and carried a bombardier operating a Norden bombsight. Only the two side-mounted forward-firing nose guns were retained. In the field, these nose guns were often removed to lighten the load if there was no apparent need for them. The crew now consisted of four--pilot, dorsal turret gunner, ventral tunnel gunner, and bombardier.
The first A-20J was created by converting A-20G-25-DO serial number 43-9230. This comprised the sole member of the A-20J-1-DO production block. The A-20J-5-DO was equivalent to the A-20G-30-DO in systems and equipment, whereas the A-20J-15-DO was equivalent to the A-20G-40-DO. The A-20J-20-DO was similar to the -15 except for revisions to the gun charging mechanisms and change of airspeed indicators from Type F-2 to Type F-1.
A total of 450 A-20Js were built, all of them by Douglas-Santa Monica. Included in this total were 169 A-20Js which were delivered to the RAF as Boston IV. RAF serials were BZ400 to BZ568. The Boston IVs retained the same armament (including the twin-gun Martin dorsal turret) as the USAAF version. They were used by Nos 13, 55, 88 and 114 Squadrons. It entered RAF service in the summer of 1944.
The A-20J was slower than the A-20G, with a maximum speed of 317 mph at 12,700 feet.
As USAAF A-20 units in Europe gradually transitioned to the A-26 Invader, the A-20J was retained as a lead ship until the glass-nosed A-26C entered service.

A-20K Havoc
Douglas A-20K Havoc "Helen” France 1945
The Douglas Boston V was the RAF designation for the glass-nosed A-20K Havoc, and was the final version of the aircraft to see service with the RAF. Ninety were received in October-November 1944, and they were used by the same squadrons as the similar Boston IV. The only difference between the Boston IV and the Boston V was the use of the R-2600-29 engine in the Boston V. Of the ninety aircraft acquired, eleven were used by the RCAF.
