The Grumman F-14 Tomcat is a supersonic, twin-engine, two-seat, variable-sweep wing aircraft. The F-14 was the United States Navy's primary maritime air superiority fighter, fleet defense interceptor and tactical reconnaissance platform from 1974 to 2006. It later performed precision strike missions once it was integrated with the Low Altitude Navigation and Targeting Infrared for Night LANTIRN system.[1] The F-14 was developed after the collapse of the F-111B project, and was the first of the American teen-series fighters which were designed incorporating the experience of air combat against MiGs during the Vietnam War.
The F-14 first deployed in 1974 with the U.S. Navy aboard USS Enterprise, replacing the F-4 Phantom II and was retired from the active U.S. Navy fleet on 22 September 2006, having been replaced by the F/A-18E/F Super Hornet.[2] As of 2009, the F-14 is in service with only the Islamic Republic of Iran Air Force, having been exported to Iran in 1976, during a time when the US had good diplomatic relations with the nation.
The F-14 Tomcat program was initiated when it became obvious that the weight and maneuverability issues plaguing the U.S. Navy variant of the Tactical Fighter Experimental (TFX) (F-111B) would not be resolved to the Navy's satisfaction. The Navy requirement was for a fleet air defense fighter (FADF) with the primary role of intercepting Soviet bombers before they could launch missiles against the carrier battle group. The Navy strenuously opposed the TFX, which incorporated the Air Force's requirements for a low-level attack aircraft, fearing the compromises would severely affect the aircraft, but were forced to participate in the program at direction of then Secretary of Defense Robert McNamara who wanted "joint" solutions to the service aircraft needs to reduce developmental costs. The prior example of the F-4 Phantom II which was a Navy and Marine Corps program later adopted by the Air Force (under similar direction) was the order of the day.
The F-111 manufacturer General Dynamics partnered with Grumman on the Navy F-111B. With the F-111B program in distress, Grumman began studying improvements and alternatives. In 1966 the Navy awarded Grumman a contract to begin studying advanced fighter designs. Grumman narrowed down these designs to its 303 design.[3] Vice Admiral Thomas Connolly, Deputy Chief of Naval Operations for Air Warfare took the developmental F-111A variant for a flight and discovered it had difficulty going supersonic and had poor carrier landing characteristics. He later testified to Congress about his concerns against the official Department of the Navy position, and in May 1968 Congress stopped funding for the F-111B, allowing the Navy to pursue an answer tailored to their requirements.
The F-14 Tomcat was designed as both an air superiority fighter and a long-range naval interceptor. The F-14 has a two seat cockpit with a canopy that affords all-round visibility. It features variable geometry wings that swing automatically during flight. For high-speed intercept, they are swept back; they swing forward to allow the F-14 to turn sharply and dogfight. It was designed to improve on the F-4 Phantom's air combat performance in most respects. The F-14's fuselage and wings allow it to climb faster than the F-4, while the twin-tail arrangement offers better stability. The F-14 is equipped with an internal 20 mm M61 Vulcan Gatling-type gun mounted on the left side, and can carry AIM-54 Phoenix, AIM-7 Sparrow, and AIM-9 Sidewinder anti-aircraft missiles.
The cockpit has two seats, arranged in tandem. The pilot and radar intercept officer (RIO) sit in Martin-Baker GRU-7A rocket-propelled ejection seats, rated from zero altitude and zero airspeed up to 450 knots.[28] They have a 360° view in a canopy that is also fitted with four mirrors, one for the RIO and the others for the pilot. The canopy is still fairly traditional; being in three parts, but the overall structure is large and gives good visibility. The crews have classical controls and many older instruments, with an analog-digital hybrid lay out. Only the pilot has flight controls.[9] No dual control version was ever made for the F-14, so the pilot starts to learn how to fly the machine using other aircraft and simulators. The main control systems are a HUD made by Kaiser, a VDI and a HSD display, that gives data on airspeed, navigation and other information. The F-14A and F-14B Tomcat do not have multi-mode displays, unlike the later F-16s and F/A-18s.
The Tomcat was also notable for its Central Air Data Computer, the integrated flight control system used in the early versions of the fighter. It used a MOS-based LSI chipset, the MP944, making it a candidate for the first microprocessor design in history.The CADC was designed and built by Garrett AiResearch.[29]
The nose of the aircraft is large because it carries not only the two person crew, but also a large number of avionics systems. The ECM and navigation suite are extremely comprehensive and complex. The main element is the Hughes AWG-9 X-band radar, which in the initial version included a lightweight 5400B digital system[9] with 32 kilobytes of RAM. The antenna dish is a 36-inch (91 cm) wide planar array, uses 10 kW of power, and has integrated IFF antennas. There are available several search and tracking modes, such as Track-While-Scan (TWS), Range-While-Search (RWS), Pulse-Doppler Single-Target Track (PDSTT), and Jam Angle Track (JAT). A maximum of 24 targets can be tracked simultaneously, and six can be engaged in TWS mode up to around 60 miles (100 km). Pulse-only STT mode has a maximum range of around 96 statute miles (150 km). The maximum search range can exceed 120 statute miles (190 km) and even a fighter can be locked onto at around 72 - 90 statute miles (120–140 km). Cruise missiles are also possible targets with the AWG-9, since this radar can lock onto and track even small objects at low altitude when in a Pulse-Doppler mode.[9] The radar antenna dish is in the nose, and most of the radar avionics are located just behind the nose, near the pilot's position. Other avionics (such as IFF, communication radios, direction-finding equipment, etc) are near the RIO's position, and are mostly integrated into the AWG-9 display system.
Tomcats also feature electronic countermeasures (ECM) and radar warning (RWR) systems, chaff/flare dispensers in the tail, fighter-to-fighter data link, and a precise inertial navigation system.[9] The early navigation system was purely inertial. Initial coordinates were programmed into the navigation computer, and a gyroscope in the system would track the aircraft's every motion. These aircraft motions were sent to the navigation computer, allowing it to calculate the jet's distance and direction from the initial starting point. Later, GPS was integrated into this inertial system, providing not only more precise navigation, but providing redundancy in case either system failed.
The chaff/flare dispensers were located on the belly, at the very tip of the tail, just to one side of the arresting hook. The dispenser contained several cylinders, into which either flares or chaff could be loaded in any combination. The RWR system was arranged with 4 antennae around the aircraft, and could roughly calculate the direction and the distance of many different types of radar from various aircraft and missile types. The RWR set could also display the status of the tracking aircraft's radar.[30] It could differentiate between search radar, tracking radar, and missile-homing radar. The electronic countermeasures system could analyze incoming radar signals and send confusing radar signals back to the source.
The original set of sensors also comprised an infrared sensor under the nose in a "chin pod": it was AN/ALR-23 with indium antimonide detectors, cooled by a self-contained Stirling cycle cryogenic system, but this proved ineffective, and was replaced with a new system. This was an optical system, Northrop AAX-1, also called TCS (TV Camera Set) and was used to help pilots visually identify and track aircraft, at least on day missions,[9] up to a range of more than 60 miles for large aircraft (a zoom function was included to help with small fighters). The TCS could be "slaved" to the radar to follow whatever the radar is tracking, and the radar could be slaved to the TCS to track whatever the camera "sees." Both the crew have access to the images on their displays. Despite its utility, for a long time most F-14s did not have the system added. Bill Gunston reported that even in 1983, only one in eight aircraft had the system fitted.[31]
A dual IR/TCS system was adopted for the later F-14D variant,[32] with an ECM antenna fitted as well in the same mast. This meant Tomcats could be configured with only an ECM antenna, or the IR sensor, or TCS, or many combinations thereof. The Tomcat's ESM system consists of many subsystems: RWR, ECM, and chaff/flare dispensers in various parts of the fuselage, nose, tail and wings. This was a marked difference with many previous fighter aircraft in that some did not even include a simple RWR.
The F-14 began replacing the F-4 Phantom II in USN service starting in September 1974 with squadrons VF-1 Wolfpack and VF-2 Bounty Hunters aboard USS Enterprise and participated in the American withdrawal from Saigon. The F-14 had its first kills on 19 August 1981 over the Gulf of Sidra in what is known as the Gulf of Sidra incident after two F-14s from VF-41 Black Aces were engaged by two Libyan Su-22 "Fitters". The F-14s evaded the short range heat seeking AA-2 "Atoll" missile and returned fire, downing both Libyan aircraft. U.S. Navy F-14s once again were pitted against Libyan aircraft on 4 January 1989, when two F-14s from VF-32 shot down two Libyan MiG-23 "Floggers" over the Gulf of Sidra in a second Gulf of Sidra incident.
Despite the attention given to the Tomcat over aerial encounters in the Gulf of Sidra, its first sustained combat baptism of fire was as a photo reconnaissance platform. The Tomcat was selected to inherit the reconnaissance mission upon departure of the dedicated RA-5C Vigilante and RF-8G Crusaders from the fleet. A large pod called the Tactical Airborne Reconnaissance Pod System (TARPS) was developed and fielded on the Tomcat in 1981. With the retirement of the last RF-8G Crusaders in 1982, TARPS F-14s became the U.S. Navy's primary tactical reconnaissance system.[36] One of two Tomcat squadrons per airwing was designated as a TARPS unit and received 3 TARPS capable aircraft and training for 4 TARPS aircrews.
While the Tomcat was being used by Iran in combat against Iraq in its intended air superiority mission over the skies of Iran in the early 1980s, the US Navy found itself flying regular daily combat missions over Lebanon to photograph activity in the Bekaa Valley. At the time, the Tomcat had been thought too large and vulnerable to be used overland, but the need for imagery was so great that Tomcat aircrews developed high speed medium altitude tactics to deal with considerable AAA and SA-7 SAM threat in the Bekaa area. An urgent combat need was stated to address the Tomcat vulnerability in this type of mission. The first exposure of a Tomcat to a SA-2 was over Somalia in April 1983 when a local battery was unaware of two Tomcats scheduled for a TARPS missions in prelude to an upcoming international exercise in vicinity of Berbera. An SA-2 was fired at the second Tomcat while conducting 10 thousand foot mapping profile at max conserve setting. The Tomcat aircrews spotted the missile launch and dove for the deck thereby evading it without damage. The unexpected demand for combat TARPS laid the way for high altitude sensors such as the KA-93 36 in (91 cm) Long Range Optics (LOROP) to be rapidly procured for the Tomcat as well as an Expanded Chaff Adapter (ECA) to be incorporated in a AIM-54 Phoenix Rail. Commercial "Fuzz buster" type radar detectors were also procured and mounted in pairs in the forward cockpit as a stop gap solution to detect SAM radars such as the SA-6. The ultimate solution was an upgrade to the ALR-67 then being developed, but it would not be ready until the advent of the F-14A+ in the latter 1980s. During the Gulf of Sidra operations in 1986, the Tomcats were used in over-water missions only due to their vulnerability overland. It was not until Desert Shield that US Navy Tomcats were introduced to overland combat operations on a regular basis.
The participation of the F-14 Tomcat in the 1991 Operation Desert Storm consisted of Combat Air Patrol (CAP) over the Red Sea and Persian Gulf and overland missions consisting of strike escort and reconnaissance. Until the waning days of Desert Storm, in-country air superiority was tasked to USAF F-15 Eagles due to the way the Air Tasking Orders (ATO) delegated primary overland CAP stations to the F-15 Eagle. The governing Rules of Engagement (ROE) also dictated a strict Identification Friend or Foe (IFF) requirement when employing Beyond Visual Range weapons such as the AIM-7 Sparrow and particularly the AIM-54 Phoenix. This hampered the Tomcat from using its most powerful weapon. Furthermore, the powerful emissions from the AWG-9 radar are detectable at great range with a radar warning receiver. Iraqi fighters routinely displayed countertactics as soon as the Tomcats "lit them up" with the AWG-9.[citation needed] The US Navy suffered its only F-14 loss from enemy action on 21 January 1991 when b/n 161430, an F-14A upgraded to an F-14A+, from VF-103 was shot down by an SA-2 surface-to-air missile while on an escort mission near Al Asad airbase in Iraq. Both crew survived ejection with the pilot being rescued by USAF Special Operations Forces and the RIO being captured and held by Iraqi troops as a POW until the end of the war.[37] The F-14 also achieved its final kill, an Mi-8 "Hip" helicopter, with an AIM-9 Sidewinder.
In 1995, F-14s from VF-14 and VF-41 participated in Operation Deliberate Force as well as Operation Allied Force in 1999, and in 1998, VF-32 and VF-213 participated in Operation Desert Fox. On 15 February 2001 the Joint Direct Attack Munition or JDAM was added to the Tomcat's arsenal. On 7 October 2001, F-14s would lead some of the first strikes into Afghanistan marking the start of Operation Enduring Freedom and the first F-14 drop of a JDAM occurred on 11 March 2002. F-14s from VF-2, VF-31, VF-32, VF-154, and VF-213 would also participate in Operation Iraqi Freedom. The F-14Ds of VF-2, VF-31, and VF-213 obtained JDAM capability in March 2003.[15] On 10 December 2005, the F-14Ds of VF-31 and VF-213 were upgraded with a ROVER III downlink for transmitting images to a ground Forward Air Controller (FAC).[16] The F-14s of VF-31 and VF-213 deployed on their last combat cruise on USS Theodore Roosevelt in 2005.
