To begin with bombing, start with high altitude flight and lift the bombing drone on a boom to 40 000 feet, this alloes for efficient engine design through the throttle hook and the theta break.

The idea is to load the bombs on revolving racks and fire them upwards and backwards over the drone. This precludes the radar signature of opening the bomb bays, reducing the radar signature from the ground. This is illustrated in c. The bombs can be coated in a radar absorbing cocoon to reduce radar signature and prevent a radar flash when the bomb emerges revealing the drone location. Instead the bomb wrapped in cocoon can fall, stabilized by a parachute, allowing the drone to separate. Explosive tape can then open the cocoon and the bomb will fall to earth with its usual terminal velocity.
If the bomb has .8 second of rise and an equal amount of fall, .8 X 32 (acceleration of gravity) = 26 feet per second. If the distance for acceleration is 1.5 feet, the acceleration is 26 X 26 / 2 X 1.5 = 225 feet per second squared or about 7 g. For a 1 000 lb bomb the force is 7 000 lb. Allowing for the release of propellant, it might total 10 000 lb. The drone might weigh 30 000 to 60 000 lb depending on fuel and weapons load. By placing one rack on either side of a single engine, the amount of rotation of the wing downward can be reduced, a,b. The plunging of the wing will increase its lift, self-stabilizing. The sudden movement could cause an increase in radar return. The time over the force is 1.5 feet divided by 1/2 the final speed of 26 feet/second = .12 second.
The entire drone can be a blended wing body. Above the bomb rack there would be a bomb door which would be the full width of the bomb and which can be opened for bomb loading and maintenance. Those would be the only times it would be opened. In the bomb door would be set a bomb aperture, a smaller door through which the bomb would be ejected for delivery, a,b,d,e.
