Douglas A-20J Havoc

The Douglas A-20J saw the reintroduction of the glass bombardier’s nose, replaced on the A-20G by a solid gun nose. While the solid nose of the A-20G had greatly improved the Havoc’s firepower, it also made navigation over Europe more difficult.

To solve this problem Douglas produced a new frameless transparent nose with a flat lower front panel, and restored the bombardier to his position prior to the A-20G. The new nose meant that all but two of the .50on nose guns had to be removed.

These aircraft were equipped with a Norden bombsight, and were used as “lead ships”, flying at the front of a formation of solid nosed A-20Gs. The entire formation would then drop their bombs on the mark set by the bomber leader. The Germans soon realised the importance of the glass nosed A-20s, and tended to target them ahead of the rest of the formation.

A total of 450 A-20Js were built, of which 165 went to the RAF, where they were known as the Boston IV. Around 80 went to the Soviet Union, while the remaining aircraft began to reach front line American units late in 1943. The A-20J (and the similar A-20K) remained in service in many units for longer than the standard solid nosed A-20s, and were used alongside the early solid nosed Douglas A-26 Invaders.
