c) Better survivability - The flight path of HGVs, in particular their ability to maneuver into and out of space, makes them extremely difficult to target using even the most sophisticated exoatmospheric anti-ballistic missiles ([[ABM]]s) such as the US [[THAAD]], Israeli [[Arrow-2]], or Russian [[S-400]] and [[S-500]]. This is because these systems were designed to release an exoatmospheric kill vehicle which engages passive, non-maneuverable targets coasting on a predictable, computable ballistic trajectory in space. The flight envelope of current generation exoatmospheric kill vehicles does not allow them to reliably engage HGVs. | c) Better survivability - The flight path of HGVs, in particular their ability to maneuver into and out of space, makes them extremely difficult to target using even the most sophisticated exoatmospheric anti-ballistic missiles ([[ABM]]s) such as the US [[THAAD]], Israeli [[Arrow-2]], or Russian [[S-400]] and [[S-500]].
