The DB-7A used the same 1,600hp Wright R-2600-A5B Double Cyclone engines as the British DB-7B/ Boston III. The Havoc II (Night Fighter) was given a solid nose designed by Martin Baker Aircraft. This was slightly longer than the nose used on the Havoc I (Night Fighter), but contained three times as many 0.303in guns. Twelve guns and their ammunition could be carried in this nose.
This has two skins for your pleasure. You will need to edit the M3D to change the skins. You need the Havoc I installed as these planes share several textures.
