The statistics are sobering: as many as 700,000 anti-aircraft missiles for man-portable air defense systems (Manpads) have been manufactured since the 1970s. Up to 7,000 missiles may be outside state control, possibly in the hands of terrorists. Since these weapons began proliferating in the 1960s, there have been some 35 documented Manpads attacks on civil aircraft.
Two companies are offering Israeli-built anti-missile systems to the civil aircraft market to protect airliners and business aircraft from the terrorist threat posed by shoulder-launched missiles, or Manpads (man-portable air defense systems).
Although not backed by the U.S. Department of Homeland Security research-and-development fund, at least four other antimissile systems are vying to protect civil aircraft from the Manpad threat: L-3 Avisys of the U.S., and Israeli groups Elisra, ELTA/IMI and Elop.
