F-37 Sabre

The F-37 Sabre is a supersonic, carrier-capable, multirole fighter aircraft designed by the SENTINEL Research and Development Unit.
The first prototype began as a rebuilt Ashford Langston A-35 Blitzen named the XF-37. It used a different design philosophy than the A-35, favoring traditional two-dimensional propulsion over vertical takeoff and landing capabilities. The advanced avionics of the A-35 were replaced with simpler equivalents, and external hardpoints were also added to accommodate a superior fighting ability. This resulted in a less maneuverable, but cheaper and lighter aircraft.
The F-37 does not use an artificial intelligence like the A-35, replacing its function with a weapon systems officer, increasing the total crew count to two.
