The final variant of the F-14 was the F-14D Super Tomcat, first delivered in 1991. As with the F-14B, the F-14D was equipped with the F110-GE-400 engines. It also included newer digital avionics systems including a glass cockpit and replaced the AWG-9 with the newer AN/APG-71 radar. Other systems included the Airborne Self Protection Jammer (ASPJ), Joint Tactical Information Distribution System (JTIDS), SJU-17(V) Naval Aircrew Common Ejection Seats (NACES), and Infrared search and track (IRST). A total of 37 new aircraft were completed, and 18 F-14A models were upgraded to D-models, designated F-14D(R) for a rebuild. Starting in 2005, some F-14Ds received the ROVER III upgrade.
