[1] Tychon expanded on the basic concept, adding a rocket motor to increase range, and modular guidance systems that could be swapped for different missions, including both conventional and nuclear attacks and reconnaissance.
After release, the aircraft continues to climb, remaining in the Air Defence Zone (ADZ) as it executes its loop and eventually flies away.
After release, the bomb would apply full up-elevator, causing it to perform the half loop and start approaching the target.
Once the internal sensors indicated it had reached horizontal at the top of the loop, the elevators reversed and caused it to enter a gliding path toward the target.
[2] It is not clear whether Momentum Bomb was ever seriously considered for development, but Bristol found the concept interesting enough to propose a more flexible version.
It retained the original stand-off nuclear attack role, but aided by a rocket motor that would allow the aircraft to stay much further from its target.
[2] In 1962, the Royal Air Force issued requirement OR.1168 for a missile that could be used as a TV guided precision guidance weapon, or be fitted with an anti-radiation seeker.
During this period, de Havilland Propellers, recently renamed Hawker Siddeley Dynamics, had been working on a TV guided design known as RG.10.
