The US Missile Defense Agency wants orbiting sensors to trace hypersonic threats. Lt. Gen. Samuel Greaves informed the McAleese/Credit Suisse convention that satellites would use mature expertise and will carry out different surveillance missions to assist justify their value. ICBMs have adopted easy ballistic path trajectories that are straightforward to trace. Increasing use of countermeasures on standard ballistic missiles — decoys or much less brightly-burning propellants — will imply missiles will want steady monitoring whereas in flight. Hypersonic warheads and hypersonic missiles will have the ability to change course which would require fixed in-flight monitoring. A brand new space-based sensor system can’t be constructed
