The A-37 was designed by BAE to replace the RAF's aging F-35 As. They will not only operate with the air force, but also with the Royal Navy. They will mainly serve as CAS aircraft, but also can act in attack, bombing, and electronic warfare. The aircraft is armed as a 30 mm multipurpose cannon and 8 hard points for bombs, rockets, and missiles. The aircraft will be stealthy because of a unique kind of jamming pod, which can be mounted on the underside of the aircraft.
