The Bluejay was originally designed as a large capacity cargo and troop hauler for the war, able to carry several armored vehicals at once or around 100 troops.
It's quad engine design gave it a max speed of close to 300mph unloaded, 200ish at max capacity.
The twin boom design was chosen for added stability while keeping a low horizontal profile, thus making it harder to hit from the side.
Very quickly the design was adapted to be a heavy bomber, so bomb bays were added to the floor of the cargo bay, and a pair of 20mm autocannon turrets were added to the roof for defense.
Then the same crazy private that began the Wren's ascension into gunships saw the Bluejay and asked the same question, "Why aren't there big guns on that?"
So the Bluejay M3 Gunship was created, keeping the defense turrets of the M2 Bomber, and adding a 40mm howitzer in the nose, a 30mm bofors cannon, 2 20mm MGs, and a 100mm light tank cannon on the Left side of the plane.
