This was going to be my entry and it was uploaded prior to that rule being created but you changed the minimum part count so it's not valid.
Thanks to MaxTeoZ for the GBU-8s

The NS-10 is an attack drone which was introduced in the early 1970s. It is designed to offer high performance but yet deliver large amounts of weapons.

As expected for such an absurd concept, this drone is manufactured by NexusCorp's ADB (Absurd Development Branch.)

Options are rather limited, but they include GBU-8 bombs and modified Cleaver missiles.

Specifications:
Max Speed: About 800mph, it was kinda laggy so I couldn't properly test that
Fuel Capacity: 12823 pounds of fuel

Features:
A built in minigun
Airbrakes if you screw up and go too fast
Several hardpoints
A built in warhead in case you run out of weapons to use
A 55 minute warranty that is voided if it is used in any way
A remote control
A large box filled with packing peanuts in which the drone is delivered
Wings
Disposable landing gear

I don't remember the controls precisely, but i think AG1 disposes of landing gear.
AG 1, AG 2, and AG 3 do something, i think
I am not sure though
You'll have to find out since life got in the way so I forgot
Other than that normal controls

As a matter of fact, the landing gear is disposable since this is intended as a suicide drone. For the event that you actually accept this, a high speed, high altitude entry is preferred since it is not exceedingly maneuverable. Then slow down a bit and stay as far as possible from the enemy base, while using the GBU-8s and modified Cleavers to attack the assets. Use the gun when you feel like you've got a good chance of hitting it. When you run out of missiles, you should then throttle all the way up and go straight for the military base. The drone will then blow up, resulting in a massive explosion.
