Douglas A-20B Havoc

The Douglas A-20B was the first version of the Havoc to be produced in large numbers for the USAAF, but it lacked self-sealing fuel tanks and did not have enough armour. In October 1940 Douglas received an order for 999 A-20Bs, all of which were produced at their Long Beach factory. The A-20B resembled the French DB-7A, having the same square edged glass panels in the nose. The lack of self-sealing fuel tanks meant that the A-20B was not really suited for front line combat duties, although 665 were sent to the Soviet Union under lend-lease. Eight more went to the US Navy as the BD-2.

The A-20B was powered by the same Wright R-2600-11 as the last few A-20As. It was armed with 0.50in Browning machine guns – two in the nose and one in the dorsal position, and one 0.30in gun in the ventral position. It could also carry the nacelle guns of the A-20A but these were rarely installed.

Douglas also received an order for 1,489 O-53 heavy observation aircraft, which would have been very similar to the A-20B, but none were built before that order was cancelled.
