Once attack helicopters attached to surface forces entered battle, they demonstrated that such results were not limited to fixed-wing attackers. At sea, Royal Navy and U.S. Navy helicopters destroyed numerous Iraqi small boats and military craft; fourteen of fifteen British Aerospace Sea Skua anti-shipping missiles launched from Westland Lynx helicopters hit their targets. French, British, and American gunships destroyed numerous Iraqi mechanized vehicles. McDonnell AH-64A Apache crews of one U.S. Army aviation brigade destroyed approximately fifty Iraqi tanks in a single encounter. Another Apache unit scored 102 hits for the expenditure of 107 Hellfire missiles, a hit rate of better than 95 percent. Overall, Apache gunships destroyed nearly 950 Iraqi tanks, personnel carriers, and miscellaneous vehicles.
