In 1973, the FMC Corporation developed and tested the XM723, which was a 21-ton tracked chassis which could accommodate three crew members and eight passengers. It initially carried a single 20 mm autocannon in a one-man turret but in 1976 a two-man turret was introduced; this carried a 25 mm autocannon like M242 or Oerlikon KBA, a co-axial machine gun, and a TOW anti-tank missile launcher. The XM723 possessed amphibious capability, nine firing ports, and spaced laminate armor on its hull. It was accepted for service with the US Army in 1980 as the Bradley Fighting Vehicle. Successive variants have been retrofitted with improved missile systems, gas particulate filter systems, Kevlar spall liners, and increased stowage. The amount of space taken up by the hull and stowage modifications has reduced the number of passengers to six.
