The F-14 received its first of many major upgrades in March 1987 with the F-14A Plus (or F-14A+). The F-14A's TF30 engine was replaced with the improved F110-GE-400 engine. The F-14A+ also received the state-of-the-art [[ALR-67]] Radar Homing and Warning (RHAW) system. Many of the avionics components, as well as the AWG-9 radar, were retained. The F-14A+ was later redesignated F-14B on 1 May 1991. A total of 38 new aircraft were manufactured and 43 F-14A were upgraded into B variants.<ref name="wapj19p1323">Lake 1994, pp. 132–133</ref><ref name="iapr3p52">Lake 2002, p. 52</ref> In the late 1990s, 81 F-14Bs were upgraded to extend airframe life and improve offensive and defensive avionics systems.
