The XA-60-Ex is an Unmanned Combat Aerial Vehicle that is developed under extreme secrecy by the U.S. Air Force.
It is a fixed-wing multi-purpose aircraft powered by scram-jet engines, giving it the ability to fly from subsonic to hyper-sonic speeds. It has long range and high maneuverability with its compact design resulting in a stealthy aircraft, making it impossible to be tracked down by radar or intercepted by other aircraft. It is armed with missiles that can be used in the air-to-ground role, air-to-ship role, and against fortifications. The control for the XA-60-Ex is separate from the main system and cannot be accessed via hacking.
Despite these advantages, these UCAVs has high instability in terms of its "Smart Controls" (the ability of complete autonomy once the order to start the mission has been given).
Each UCAV destroyed rewards the player 10,000 points as a destruction bonus.
In Time Crisis 4, the Hamlin Battalion attacked the Colorado Air Force Base where the XA-60-Ex UCAVs are stored. After using Terror Bites to overcome the base's defense system, these UCAVs are launched with the intention of destroying every major city in the United States. After the V.S.S.E. agents, Captain William Rush and the National Guard soldiers stormed the base and defeated the Hamlin Battalion soldiers and Gregory Barrows, the V.S.S.E. agents pressed a big red button on the control computers which sends the "Ceasefire" order (self-destructs all nuclear missiles that the UCAVs have already launched and signals the UCAVs to return to base).
