The most determined effort to develop a small, cheap guided weapon, though, is the Forward Firing Miniature Munition (F2M2, or Spike missile), from the NavalAirWeaponsStation in China Lake, California.
The RQ-4A Global Hawk drone crashed during a routine training flight from NavalAirStation Patuxent River, according to Jamie Cosgrove, a spokeswoman for the Unmanned Aviation and Strike Weapons Program at the base.
