The Lockheed Martin F Lightning II is an American family of single-seat, do 178b resume, single-engine, all-weather stealth multirole combat aircraft that is intended to perform both air superiority and strike missions. It is also able to provide electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Lockheed Martin is the prime F contractor, with principal partners Northrop Grumman and BAE Systems.
The aircraft descends from the Lockheed Martin Xwhich in beat the Boeing X to win the Joint Strike Fighter JSF program. Its development is principally funded by the United States, with additional funding from program partner countries from NATO and close U. allies, including the Do 178b resume Kingdom, do 178b resume, Australia, Canada, Italy, Norway, Denmark, the Netherlands, and formerly Turkey.
The program has drawn much scrutiny and criticism for its unprecedented size, complexity, ballooning costs, and much-delayed deliveries, with numerous technical flaws still being corrected. The FB entered service with the U. Marine Corps in Julydo 178b resume, followed by the U. Air Force FA in August and the U. Navy FC in February plans to buy 2, Fs throughwhich will represent the bulk of the crewed tactical airpower of do 178b resume U.
Air Force, Navy, and Marine Corps for several decades. The F was the product of the Joint Strike Fighter JSF program, which was the merger of various combat aircraft programs from the s and s. Marine Corps USMC and the U. Royal Navy. Under one of ASTOVL's classified programs, the Do 178b resume STOVL Fighter SSFLockheed Skunk Works conducted research for a stealthy supersonic STOVL fighter intended for both U. Air Force USAF and USMC; a key technology explored was the shaft-driven lift fan SDLF system.
Lockheed's concept was a single-engine canard delta aircraft weighing about 24, lb 11, kg empty. ASTOVL was rechristened as the Common Affordable Lightweight Fighter CALF in and involved Lockheed, McDonnell Douglasand Boeing, do 178b resume. Inthe Joint Advanced Strike Technology JAST program emerged following the cancellation of the USAF's Multi-Role Fighter MRF and U.
MRF, a program for a relatively affordable F replacement, was scaled back and delayed due to post-Cold War defense posture easing F fleet usage and thus extending its service life as well as increasing budget pressure from the F program.
International participation is a key aspect of the JSF program, starting with United Kingdom participation in the ASTOVL program. Many international partners requiring modernization of their air forces were interested in the JSF. Consequently, the aircraft was developed in cooperation with international partners and available for export.
Boeing and Lockheed Martin were selected in early for CDP, do 178b resume, with their concept demonstrator aircraft designated X and X respectively; the McDonnell Douglas team was eliminated do 178b resume Northrop Grumman and British Aerospace joined the Lockheed Martin team.
Each firm would produce two prototype air vehicles to demonstrate conventional takeoff and landing CTOLcarrier takeoff and landing CVand STOVL. The key aspect of the X that enabled STOVL operation, the SDLF system consists of the lift fan in the forward center fuselage that could be activated by engaging a clutch that connects the driveshaft to the turbines and thus augmenting the thrust from the engine's swivel nozzle.
Research from prior aircraft incorporating similar systems, such as the Convair Model[N 4] Rockwell XFVand Yakovlev Yakwere also taken into consideration. Lockheed Martin's commonality strategy was to replace the STOVL variant's SDLF with a fuel tank and the aft swivel nozzle with a two-dimensional thrust do 178b resume nozzle for the CTOL variant. This enabled greater commonality between all three variants, as the commonality goal was still important at this stage of the design.
The XA first flew on 24 October and conducted flight tests for subsonic and supersonic flying qualities, handling, range, and maneuver performance. The XB would successfully demonstrate the SDLF system by performing stable hover, vertical landing, do 178b resume, and short takeoff in less than ft m. As the JSF program moved into the System Development and Demonstration phase, the X demonstrator design was modified to create the F combat aircraft.
The forward fuselage was lengthened by 5 inches 13 cm to make room for mission avionics, while the horizontal stabilizers were moved 2 inches 5. The diverterless supersonic inlet changed from a four-sided to a three-sided cowl shape and was moved 30 inches 76 cm aft. The fuselage section was fuller, the top surface raised by 1 inch 2.
Following the designation of the X prototypes, do 178b resume, the three variants were designated FA CTOLFB STOVLand FC CV. Prime contractor Lockheed Martin performs overall systems integration and final assembly and checkout FACO[N 6] while Northrop Grumman and BAE Systems supply components for mission systems and airframe.
Adding the systems of a fighter aircraft added weight. By Septemberthese efforts had reduced the FB's weight by over 3, pounds 1, kgdo 178b resume, while the FA and FC were reduced in weight by 2, pounds 1, kg and 1, pounds kg respectively.
The first FA, designated AA-1, was rolled out in Fort Worth, Texason 19 February and first flew on 15 December The aircraft's software was developed as six releases, or Blocks, for SDD. The first two Blocks, 1A and 1B, readied the F for initial pilot training and multi-level security.
Block 2A improved the training capabilities, while do 178b resume was the first combat-ready release planned for the USMC's Initial Operating Capability IOC. Block 3i retains the capabilities of 2B while having new hardware and was planned for the USAF's IOC.
The final release for SDD, Block 3F, would have full flight envelope and all baseline combat capabilities. Alongside software releases, each block also incorporates avionics hardware updates and air vehicle improvements from flight and structural testing.
Testing found several major problems: do 178b resume FB airframes had premature cracking, [N 8] the FC arrestor hook design was unreliable, fuel tanks were too vulnerable to lightning strikes, the helmet display had problems, and more. Software was repeatedly delayed due to its unprecedented scope and complexity. Indo 178b resume, the DoD Joint Estimate Team JET estimated that the program was 30 months behind the public schedule.
The first combat-capable Block 2B configuration, do 178b resume, which had basic air-to-air and strike capabilities, was declared ready by the USMC in July The F is expected to be continually upgraded over its lifetime.
The first upgrade program, called Continuous Capability Development and Delivery C2D2 began in and is currently planned to run to The near-term development priority of C2D2 is Block 4, which would integrate additional weapons, including those unique to international customers, refresh the avionics, improve ESM capabilities, do 178b resume, and add Remotely Operated Video Enhanced Receiver ROVER support.
Defense contractors have offered upgrades to the F outside of official program contracts. InNorthrop Grumman disclosed its development of a directional infrared countermeasures DIRCM suite, named Threat Nullification Defensive Resource ThNDR.
The countermeasure system would share the same space as the Distributed Aperture System DAS sensors and acts as a laser missile jammer to protect against infrared-homing missiles. The United States is the primary customer and financial backer, with planned procurement of 1, do 178b resume, FAs for the USAF, do 178b resume, FBs and 67 FCs for the USMC, and FCs for the USN.
and eight major partner nations would acquire over 3, Fs through In December Japan announced its intention to purchase 42 Fs to replace the F-4 Phantom IIwith 38 to be assembled domestically and do 178b resume beginning in Italy reduced its order from to 90 Fs in In JanuarySingapore announced its plan to buy a small number of Fs for an evaluation of capabilities and suitability before deciding on more to replace its F fleet. The Swiss anti-military group GSoAsupported by the Greens and Social Democratsintends to contest the purchase in a national referendum.
The F is a family of single-engine, supersonic, stealth multirole fighters. The F has a wing-tail configuration with two vertical stabilizers canted for stealth. Flight control surfaces include leading-edge flapsflaperons[N 10] ruddersand all-moving horizontal tails stabilators ; leading edge root extensions also run forwards to the inlets. The relatively short foot wingspan of the FA and FB is set by the requirement to fit inside USN amphibious assault ship parking areas and elevators; the FC's larger wing is more fuel efficient, do 178b resume.
Do 178b resume powerful F engine gives good subsonic acceleration and energy, with supersonic dash in afterburner. The large stabilitors, leading edge extensions and flaps, and canted rudders provide excellent high alpha angle-of-attack characteristics, with a trimmed alpha of 50°.
Relaxed stability and fly-by-wire controls provide excellent handling qualities and departure resistance. The F's mission do 178b resume are among the most complex aspects of the aircraft. The avionics and sensor fusion are designed to enhance the pilot's situational awareness and command and control capabilities and facilitate network-centric warfare.
The F was designed with sensor intercommunication to provide a cohesive image of the local battlespace and availability for any possible use and combination with one another; for example, the APG radar also acts as a do 178b resume of the electronic warfare system.
The APG radar uses electronic scanning for rapid beam agility and incorporates passive and active air-to-air modes, strike modes, and synthetic aperture radar SAR capability, with multiple target track-while-scan at ranges in excess of 80 nmi km.
The antenna is tilted backwards for stealth. It also provides sensor fusion of radio frequency and infrared tracking functions, do 178b resume, geolocation threat targeting, and multispectral image countermeasures for self-defense against missiles. The electronic warfare system is capable of detecting and do 178b resume hostile radars. The all-aspect target direction and identification can be shared via MADL to other platforms without compromising low observabilitywhile Link 16 is present for communication with legacy do 178b resume. The F was designed from the outset to incorporate improved processors, sensors, and software enhancements over its lifespan.
Technology Refresh 3, which includes a new core processor and a new cockpit display, is planned for Lot 15 aircraft. Stealth is a key aspect of the F ' s design, do 178b resume, and radar cross-section RCS is do 178b resume through careful shaping of the airframe and the use of radar-absorbent materials RAM ; visible measures to reduce RCS include alignment of edges, do 178b resume, serration of skin panels, and the masking of the engine face and turbine.
Additionally, the F's diverterless supersonic inlet DSI uses a compression bump and forward-swept cowl rather than a splitter gap or bleed system to divert do 178b resume boundary layer away from the inlet duct, eliminating the diverter cavity and further reducing radar signature.
Noise from the F caused concerns in residential areas near potential bases for the aircraft, and residents near two such bases— Luke Air Force BaseArizona, and Eglin Air Force Base AFBFlorida—requested environmental impact studies in and respectively. The glass cockpit was designed to give the pilot good situational awareness. The main display is a by 8-inch 50 by 20 cm panoramic touchscreenwhich shows flight instruments, stores management, CNI information, and integrated caution and warnings; the pilot can customize the arrangement of the information.
Below the main display is a smaller stand-by display. The Martin-Baker US16E ejection seat is launched by a twin-catapult system housed on side rails. For life support, do 178b resume, an onboard oxygen-generation system OBOGS is fitted and powered by the Integrated Power Package IPPwith an auxiliary oxygen bottle and backup oxygen system for emergencies.
The Vision Systems International [N 12] helmet display is a key piece of the F's human-machine interface. Instead of the head-up display mounted atop the dashboard of earlier fighters, the HMDS puts flight and combat information on the helmet visor, do 178b resume, allowing the pilot to see it no matter which way he or she is facing.
The HMDS allows an F pilot to fire missiles at targets even when the nose of the aircraft is pointing elsewhere by cuing missile seekers at high angles off-boresight. To preserve its stealth shaping, the F has two internal weapons bays with four weapons stations, do 178b resume.
The two outboard weapon stations each can carry ordnance up to 2, do 178b resume, lb 1, do 178b resume, kgdo 178b resume, or 1, lb kg for FB, while the two inboard stations carry air-to-air missiles. Air-to-surface weapons for the outboard station include the Joint Direct Attack Munition JDAMPaveway series of bombs, Joint Standoff Weapon JSOWand cluster munitions Wind Corrected Munitions Dispenser. Two compartments behind the weapons bays contain flares, do 178b resume, chaffand towed do 178b resume. The aircraft can use six external weapons stations for missions that do not require stealth.
The external wing stations can carry large air-to-surface weapons that would not fit inside the weapons bays such as the AGM Joint Air to Surface Stand-off Missile JASSM cruise missile. An air-to-air missile load of eight AIMs and two AIM-9s is possible using internal and external weapons stations; a configuration of six 2, lb kg bombs, two AIMs and two AIM-9s can also be arranged.
