The AMSA was to be a four-engine bomber capable of supersonic speeds at either high or low altitude. It will have a gross weight of 350,000 to 400,000 pounds, able to deliver very large payloads to great distances. The internal weapons bay permitted to carry large nonnuclear munition payloads. The aircraft design was to be such as to reduce the probability of detection, incorporating other survival and penetration characteristics such as short takeoff and landing to permit widespread dispersal, provisions for decoy and defense missiles, and electronic countermeasures. AMSA was expected to become an effective weapon system across a wide spectrum of possible conflict situations.
