Variants

The Grumman F-14 Tomcat is an American supersonic, twin-engine, two-seat, twin-tail, variable-sweep wing fighter aircraft.

A total of 712 F-14s were built from 1969 to 1991.

F-14 assembly and test flights were performed at Grumman’s plant in Calverton on Long Island, New York.

Grumman facility at nearby Bethpage, New York was directly involved in F-14 manufacturing and was home to its engineers.

The airframes were partially assembled in Bethpage and then shipped to Calverton for final assembly.

Various tests were also performed at the Bethpage Plant.

Over 160 of the U.S. aircraft were destroyed in accidents.

F-14A

The F-14A was the initial two-seat, twin-engine, all-weather interceptor fighter variant for the U.S. Navy.

It first flew on 21 December 1970. The first 12 F-14As were prototype versions (sometimes called YF-14As).

Modifications late in its service life added precision strike munitions to its armament.

The U.S. Navy received 478 F-14A aircraft and 79 were received by Iran.

The final 102 F-14As were delivered with improved Pratt & Whitney TF30-P-414A engines.

Additionally, an 80th F-14A was manufactured for Iran, but was delivered to the U.S. Navy.

F-14B

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 GE F110-GE-400 engine.

The F-14A+ also received the state-of-the-art ALR-67 Radar Homing and Warning (RHAW) system.

Much 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 48 F-14A were upgraded into B variants.

The TF30 had been plagued from the start with susceptibility to compressor stalls at high AoA and during rapid throttle transients or above 30,000 ft (9,100 m).

The F110-400 engine provided a significant increase in thrust, producing 23,400 lbf (104 kN) with afterburner at sea level, which rose to 30,200 lbf (134 kN) at Mach 0.9.

The increased thrust gave the Tomcat a better than 1:1 thrust-to-weight ratio at low fuel quantities.

The basic engine thrust without afterburner was powerful enough for carrier launches, further increasing safety.

Another benefit was allowing the Tomcat to cruise comfortably above 30,000 ft (9,100 m), which increased its range and survivability.

The F-14B arrived in time to participate in Desert Storm.

In the late 1990s, 67 F-14Bs were upgraded to extend airframe life and improve offensive and defensive avionics systems.

The modified aircraft became known as F-14B Upgrade.

F-14D

The final variant of the F-14 was the F-14D Super Tomcat.

The F-14D variant was first delivered in 1991.

The original Pratt & Whitney TF30 engines were replaced with General Electric F110-GE-400 engines, similar to the F-14B.

The F-14D 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).

The GE F110-GE-400 engine provided increased thrust and additional endurance to extend range or to stay on station much longer.

In the overland attack role this gave the F-14D 60 percent more striking range or one-third more time on station.

The rate of climb was increased by 61 percent.

The F110’s increased thrust allowed almost all carrier launches to be made in military (dry) power.

While this did result in fuel savings, the main reason not to use afterburner during carrier launches was that if an engine failed the F110’s thrust in full afterburner would produce a yawing moment too abruptly for the pilot to correct.

Thus the launch of an F-14D with afterburner was rare, while the F-14A required full afterburner unless very lightly loaded.

Although the F-14D was to be the definitive version of the Tomcat, not all fleet units received the D variant.

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.

An upgrade to the F-14D’s computer software to allow AIM-120 AMRAAM missile capability was planned but was later terminated to free up funding for LANTIRN integration.

Starting in 2005, some F-14Ds received the ROVER III upgrade.
