Lockheed Martin F-35 Lightning II

The F-35 Lightning II joint strike fighter (JSF), is being developed by Lockheed Martin Aeronautics Company for the US Air Force, Navy and Marine Corps and the UK Royal Navy.

The stealthy, supersonic multirole fighter was designated the F-35 Lightning II in July 2006. The JSF is being built in three variants: a conventional take-off and landing aircraft (CTOL) for the US Air Force; a carrier variant (CV) for the US Navy; and a short take-off and vertical landing (STOVL) aircraft for the US Marine Corps and the Royal Navy. A 70%-90% commonality is required for all variants.

The requirement is for: USAF F-35A air-to-ground strike aircraft, replacing F-16 and A-10, complementing F-22 (1763); USMC F-35B – STOVL strike fighter to replace F/A-18B/C and AV-8B (480); UK RN F-35C – STOVL strike fighter to replace Sea Harriers (60); US Navy F-35C – first-day-of-war strike fighter to replace F/A-18B/C and A-6, complementing the F/A-18E/F (480 aircraft).

Lightning II Joint Strike Fighter (JSF) development

The Lockheed Martin JSF team includes Northrop Grumman, BAE Systems, Pratt and Whitney and Rolls-Royce. Final assembly of the aircraft took place at Lockheed Martin’s Fort Worth plant in Texas.

Major subassemblies were produced by Northrop Grumman Integrated Systems at El Segundo, California and BAE Systems at Samlesbury, Lancashire, England. BAE Systems is responsible for the design and integration of the aft fuselage, horizontal and vertical tails and the wing-fold mechanism for the CV variant, using experience from the Harrier STOVL programme. Terma of Denmark and Turkish Aerospace Industries of Turkey are supplying sub-assemblies for the centre fuselage.

In January 2001, the UK MoD signed a memorandum of understanding to co-operate in the SDD (system development and demonstration) phase of JSF and, in September 2002, selected the STOVL variant to fulfil the future joint combat aircraft (FJCA) requirement. Following the contract award, other nations signed up to the SDD phase are: Australia, Canada, Denmark, Italy, Netherlands, Norway, Singapore and Turkey.

The development of the centre fuselage for the first international F-35 joint strike fighter began on 30 October 2009. It is being developed by Northrop Grumman, principally for the UK. The centre fuselage including composite air inlet ducts were supplied by Turkish Aerospace Industries (TAI).

The F-35B short take-off and vertical landing (STOVL) variant, designated BK-1, completed its assembly in November 2011. It will be delivered to the UK Ministry of Defence by 2012. The variant is being developed as part of the low-rate initial production (LRIP) 3 and is expected to produce 138 F-35Bs for the UK.

Training centre at Elgin Air Force Base and F-35 operational bases

An integrated training centre for the F-35 fighter programme has been set up at Elgin Air Force Base in the US. The training centre was inaugurated in November 2010 and will be fully operational by 2013.

A total of 11 base locations were unveiled for the F-35 Lightning joint strike fighter. Of the 11, six were selected to carry out operations and five to be training bases.

The six bases implementing F-35 operations are Burlington International Airport Guard Station, Vermont; Hill AFB, Utah; Jacksonville International Airport Air Guard Station, Florida; Mountain Home AFB, Idaho; Shaw AFB, South Carolina; and McEntire Air Guard Base, South Carolina. The five bases for training purposes are Boise Air Terminal Air Guard Station, Idaho; Eglin Air Force Base, Florida; Holloman Air Force Base, New Mexico; Luke AFB, Arizona; and Tucson International Airport Air Guard Station, Arizona.

The selected locations will be finalised after implementing environmental impact analysis.

Concept demonstration phase led by Boeing and Lockheed

The concept demonstration phase of the programme began in November 1996 with the award of contracts to two consortia, led by Boeing Aerospace and Lockheed Martin. The contracts involved the building of demonstrator aircraft for three different configurations of JSF, with one of the two consortia to be selected for the development and manufacture of all three variants.

In October 2001, an international team led by Lockheed Martin was awarded the contract to build JSF. An initial 22 aircraft (13 flying test aircraft and eight ground-test aircraft) will be built in the programme’s system development and demonstration (SDD) phase. Flight testing will be carried out at Edwards Air Force Base, California, and Naval Air Station, Patuxent River, Maryland.

In April 2003, JSF completed a successful preliminary design review (PDR). The critical design review (CDR) for the F-35A was completed in February 2006, for the F-35B in October 2006 and for the F-35C in June 2007. The first flight of the CTOL F-35A took place on 15 December 2006.

Low-rate initial production (LRIP) for the F-35A/B was approved in April 2007 with an order for two CTOL aircraft. An LRIP 2 contract for six CTOL aircraft was placed in July 2007. The STOVL F-35B was rolled out in December 2007 and made its first flight, a conventional take-off and landing, in June 2008. STOVL flights began in early 2009. An LRIP contract for six F-35B STOVL aircraft was placed in July 2008.

First flights of Lockheed’s F-35 variations

The F-35C took off on its first flight in November 2011. The F-35A fighter was delivered to Eglin Air Force Base in October 2011 and is under functional test; the F-35B was inaugurated in October 2011.

The first flight of the F-35 is powered by the GE Rolls-Royce F136 engine. Critical design review was completed in February 2008.

By the end of 2006, Australia, Canada, the Netherlands and the UK had signed the MoU for the F-35 Production, Sustainment and Follow-on Development (PSFD) phase.

Norway and Turkey (requirement 100 F-35A) signed in January 2007. Denmark and Italy (requirement 131 F-35A and B) signed in February 2007. In May 2008, Israel requested the sale of 25 F-35A aircraft with 50 options.

Participating nations were to sign up to the initial operation test and evaluation (IOT&E) phase by the end of February 2009. In October 2008, Italy announced that it intended not to participate in the IOT&E.

In September 2004, Lockheed Martin announced that, following concerns over the weight of the STOVL F-35B, design changes had reduced the aircraft weight by 1,225kg while increasing propulsion efficiency and reducing drag. The weight requirements will also call for a smaller internal weapons bay than on the other variants.

International orders and deliveries to forces in the UK, US and Canada

The USAF ordered 32 new F-35A aircraft in 2010. USMC ordered 16 F-35B aircraft and is considering more 13 more aircraft. The USN ordered seven F-35Bs aircraft in 2009, and 12 F-35s were delivered to the US in 2011.

The UK ordered two F-35B’s in 2009 and one F-35C in 2010. The Netherlands ordered three F-35A aircraft, one in 2010 and two in 2011. Australia decided to purchase 14 F-35A aircraft in October 2010.

Canada also announced its choice of F-35 aircraft for its future fighter requirements. The Italian Parliament has approved the purchase of 131 F-35 aircraft and construction of a final assembly facility at Cameri Air Base.

Design differences between variants of the Joint Strike Fighter

1145207739

In order to minimise the structural weight and complexity of assembly, the wingbox section integrates the wing and fuselage section into one piece. To minimise radar signature, sweep angles are identical for the leading and trailing edges of the wing and tail (planform alignment).

The fuselage and canopy have sloping sides. The seam of the canopy and the weapon bay doors are sawtoothed and the vertical tails are canted at an angle.

si-620-f-35-features

The marine variant of JSF is very similar to the air force variant, but with a slightly shorter range because some of the space used for fuel is used for the lift fan of the STOVL propulsion system.

F-35B – Lockheed Martin

The main differences between the naval variant and the other versions of JSF are associated with the carrier operations. The internal structure of the naval version is very strong to withstand the high loading of catapult-assisted launches and tailhook arrested landings.

The aircraft has larger wing and tail control surfaces for low-speed approaches for carrier landing. Larger leading edge flaps and foldable wingtip sections provide a larger wing area, which provides an increased range and payload capacity.

Capture14

F-35C – Lockheed Martin

The canopy (supplied by GKN Aerospace), radar and most of the avionics are common to the three variants.

The centre fuselage assembling process includes loading of an all-composite air inlet duct into a special tooling structure called a jig, followed by 18 major steps such as bonding metal frames around the duct. The frames serve to brace and position the duct properly within the centre fuselage.

Revolutionary situational awareness
The next-generation user interface serves as the pilot’s primary display system, and virtual capabilities enable them to see through the bottom of the fuselage or directly at a target. With an uninterrupted display of flight information and sensor data, the pilot experiences extreme spatial orientation, superior weapons targeting, and tactical superiority–both day and night.

Integrated HUD, Display and Night Vision
The head-up display (HUD), helmet-mounted display, and visor-projected night vision are fully integrated to provide pilots with unprecedented capability in the fighter cockpit. They can target their weapons and maintain advanced spatial orientation while continually monitoring critical flight information.

Bi-ocular display system with full day and night vision
Advanced bi-ocular, 30-by-40-degree-wide field-of-view has 100 percent overlap. For night missions, the HMDS projects directly onto the visor, eliminating the need for separate night-vision goggles

Visual targeting
The HMDS enables the pilot to target weapons by looking at and designating targets, and target verification when receiving steering cues from onboard sensors or via datalink.

High performance design with optimal center of gravity
The lightweight design has an optimal center of gravity and Active Noise Reduction (ANR). The custom helmet liner ensures precise fit and comfort for reduced pilot fatigue. Source rockwellcollins.com

Multifunction Advanced Data Link (MADL)

The MADL is a high-data-rate, directional communications link that allows secure transmission of coordinated tactics and engagement for the fifth-generation fighter when operating in high-threat environments.

According to the Air Force, the F-35 has unprecedented situational awareness. The F-35’s advanced sensor package is designed to gather, fuse and distribute more information than any fighter in history, which gives pilots a decisive advantage over all adversaries.

“Having a common battlefield picture is one of the greatest assets in combat,” LeClair said. “This capability must be proven to be secure and ensure maximum interoperability between 4th and 5th-generation fighters. The F-35 has an incredible capability to show the entire tactical picture and being able to share this tactical picture with all forces is critical to maximizing lethality, survivability and minimizing the risk of fratricide.” Source realcleardefense.com

AIM-120C AMRAAM air-to-air missile

a6cb6e749b86f70884ca784cf15d0acd

AIM-120 AMRAAM

The AIM-120 AMRAAM is a medium-range, air-to-air missile designed to meet the requirements of the United States and allied nations. The AIM-120 missile is faster, smaller and lighter than its predecessor the AIM-7 Sparrow medium-range missile and also has improved capabilities against low-altitude targets. AMRAAM incorporates active radar seeker with mid-course inertial navigation making it less dependent on aircraft’s fire control radar. That capability enables simultaneous AMRAAM launching against different targets. For better performance AMRAAM can receive target location updates from the radar system of the launch aircraft. It has a blast fragmentation warhead detonated by a proximity fuse.

The AIM-120C missile is the latest AMRAAM variant and is reprogrammable like the AIM-120B. The AIM-120C has smaller control surfaces to fulfill F/A-22’s internal carriage requirements and also features an improved warhead. The AIM-120C missile has been sold successfully to many countries in two main variants the AIM-120C5 and the AIM-120C7. Beginning in 2008 the AIM-120C was replaced by the AIM-120D as the standard production model for the AMRAAM missile.

GUB 31/B JDAM

The Joint Direct Attack Munition (JDAM) is a tail kit which converts free fall unguided bombs into precision-guided weapons. The tail section contains a GPS/INS guidance system that guides the JDAM bomb through the selected target. The JDAM bombs is available for all the fighting aircraft of the US inventory (B-1B, B-2A, B-52H, F-16C/D, F/A-18C/D, F/A-18E/F, F-15E, F/A-22, F-35, A-10A, S-3, F-117, AV-8B, and F-14A/B/D) as well as aircraft in development and foreign aircraft. The JDAM were used for the first time during operation Allied Force in 1999.

The JDAM bombs can be released in day/night and adverse weather at up to 15 miles away from the selected target. The Pentagon claims that JDAM bomb accuracy is about 13 meters CEP (Circular Error Probable), but according to Boeing sources JDAM accuracy is 9.6 meters CEP. Without the GPS guidance system using only the INS guidance system JDAM accuracy is 30 meters. The advanced capabilities of these smart bombs make possible to attack multiple targets simultaneously as it has been demonstrated during operational representative tests carried out by a B-2 Spirit dropping 16 JDAMs against several targets in a single mission.

The GBU-31 bomb can use the BLU-109 or the Mk-84 warhead to destroy bunkers and hardened targets.

AIM-132 ASRAAM – BAE Systems

The AIM-132 ASRAAM (Advanced Short Range Air-to-Air Missile) missile has been designed to provide excellent performance in short range air-to-air engagements. The ASRAAM has been selected by the United Kingdom and the Australian Air Force for their Tornado F3, Harrier, F/A-18 and Eurofighter-Typhoon aircraft.

The ASRAAM features an advanced IR seeker (128×128 resolution) and the capability to operate in heavy ECM environments. It receives the target coordinates from the aircraft’s sensors (radar and IRST), the pilot’s helmet mounted sight or even from its own IR imaging sensor in the search and track mode. Its high speed and maneuverability provides the ASRAAM with a high kill probability once fired. ASRAAM has a single blast fragmentation warhead detonated by impact and laser proximity fuze.

The Russian AA-11, the American AIM-9X and the German IRIS-T missiles are the AIM-132 ASRAAM foreign counterparts. United Kingdom and Australia remain as the only known operators for ASRAAM as of September 2004.

B61 nuclear bomb

Capture

The F-35 Joint Strike Fighter is slated to be armed with the B61 nuclear bomb as early as 2020, but could carry the weapon sooner, a general said.

The stealthy fifth-generation fighter made by Lockheed Martin Corp. is set to be fitted with the B61-12 Mod gravity bomb — the latest variant — sometime between 2020 and 2022, Air ForceBrig. Gen. Scott Pleus told Military.com during a recent interview at the Pentagon. Source military.com

“Detailed risk reduction activities have been completed ensuring the F-35A is fully compatible with the B61-12 weapon. Planning for Block 4 nuclear certification efforts have begun in anticipation of initial B61-12 integration on the F-35A this year,” Maj. Emily Grabowski, Air Force Spokeswoman, told Warrior Maven.

The Block 4 F-35, to fully emerge in the next decade, contains more than 50 technical adjustments to the aircraft designed as software and hardware builds — to be added in six-month increments between April 2019 to October 2024, she added.

The latest version of the B61 thermonuclear gravity bomb, which has origins as far back as the 1960s, is engineered as a low-to-medium yield strategic and tactical nuclear weapon, according to nuclearweaponsarchive.org, which also states the weapon has a “two-stage” radiation implosion design.

The most current Mod 12 version has demonstrated a bunker-buster earth-penetrating capability, according to the Federation of American Scientists (FAS).

“B61-12 is designed to have four selectable explosive yields: 0.3 kilotons (kt), 1.5 kt, 10 kt and 50 kt,” FAS writes.

Utilizing speed, maneuverability and lower-altitude flight when compared to how a bomber such as a B-2 would operate, a nuclear-capable F-35 presents new threats to a potential adversary. In a tactical sense, it seems that a high-speed F-35, fortified by long-range sensors and targeting technologies, might be well positioned to identify and destroy mobile weapons launchers or other vital, yet slightly smaller on-the-move targets. Furthermore, the B61 Mod 12 is engineered with a special “Tail Subassembly” to give the bomb JDAM-type GPS accuracy, giving a new level of precision targeting, according to data provided by the Federation of American Scientists.

Hypersonic Air-breathing Weapon Concept hypersonic missile

In September 2002, General Dynamics Armament and Technical Products was selected as the gun system integrator. General Dynamics was awarded a contract for the internally mounted 25mm GAU-22/A gun system for the air force CTOL variant in November 2008. General Dynamics is developing an external gun system for the carrier and marine variants.

25mm GAU-22/A gun system

25mm_GAU-22_gatling_gun2

gd-ots.com

The 25mm GAU-22/A is an externally powered Gatling gun developed for both the internal and external F-35 gun systems. This four-barrel gun is a derivative of our highly successful five-barrel, 25mm GAU-12/U gun.

Each of the four gun barrels has a breech bolt assembly that fires once per gun revolution. This ensures long barrel and breech life by distributing the heat and firing forces over all four barrels and breech positions. Continuous rotary motion reduces the impact loads on gun components, extending parts life and resulting in extremely high gun reliability.

The GAU-22/A is over 40 pounds lighter and occupies 20 percent less volume than the comparably equipped 5-barrel counterpart. The demonstrated versatility, coupled with significant combat lethality, makes the GAU-22/A gun an ideal candidate for air, land and sea platforms.

The DAS provides:

  • Missile detection and tracking
  • Launch point detection
  • Situational awareness IRST & cueing
  • Weapons support
  • Day/night navigation

In addition to developing the EO DAS, Northrop Grumman Electronic Systems is supplying the F-35’s AN/APG-81 advanced electronically scanned array (AESA) fire-control radar. The AESA radar is designed to enable the pilot to effectively engage air and ground targets at long range, while also providing outstanding situational awareness.

F-35 DAS and APG-81 radar demonstrate ability to detect, track, target ballistic missiles

maxresdefault

Northrop Grumman Corporation recently demonstrated the ballistic missile detection, tracking and targeting capabilities of the company’s AN/AAQ-37 distributed aperture system (DAS) and AN/APG-81 active electronically scanned array (AESA) radar, both of which are featured on the F-35 Joint Strike Fighter (JSF) aircraft. Northrop Grumman’s DAS and APG-81 autonomously detected, tracked and targeted multiple, simultaneous ballistic rockets. The DAS autonomously detected all five rockets, launched in rapid succession, and tracked them from initial launch well past the second stage burnout. Press release | Watch the video.

F-35 DAS demonstrates hostile fire detection capability

f-35-ground-fire

While being flown on Northrop Grumman’s BAC 1-11 test aircraft, the DAS detected and located tank fire from an operationally significant distance. In addition to artillery, the system is able to simultaneously detect and pinpoint the location of rockets and anti-aircraft artillery fired in a wide area. Although hostile fire detection is not an F-35 requirement for the DAS, the system design makes it ideal for this mission. This inherent capability enables DAS to harvest, process and deliver key battlespace information to ground forces and other aircraft autonomously, without the need for cueing or increasing pilot workload. Press release | Watch the videoSource northropgrumman.com

Early production lots of all three variants will be powered by the Pratt and Whitney afterburning turbofan F-135 engine, a derivative of the F119 fitted on the F-22. Following production aircraft will be powered by either the F135 or the F-136 turbofan being developed by General Electric and Rolls-Royce. However, in the 2007 US Military Budget, published in February 2006, no funding was allocated for the development of the F-136 engine. The US Congress voted to restore funding for the F-136 in October 2006.

Pratt and Whitney afterburning turbofan F-135 engine

pw.utc.com

The Pratt & Whitney F135 two-spool afterburning turbofan engine powers all three variants of the Lockheed Martin F-35 Lightning II – Joint Strike Fighter. The F135 propulsion system is the most powerful fighter engine ever developed.

The F135-PW-100 powers the U.S. Air Force F-35A Conventional Take-Off and Landing (CTOL) variant and provides 28,000 pounds of thrust or as much as 43,000 pounds with afterburner.

The more complex (and almost twice as expensive) F135-PW-600 system is used on the Marine Corps F-35B Short Take-Off and Vertical Landing (STOVL) variant. The system is basically an F135 engine coupled to a lift system manufactured by Rolls-Royce (Rolls-Royce LiftSystem). The Rolls-Royce LiftSystem is comprised of a lift fan, a driveshaft, the 3 Bearing Swivel Module (3BSM), and two roll posts. The driveshaft connects the F135 engine to the lift fan and delivers as much as 29,000 shp. The lift fan provides the forward vertical lift. It is a 50-inch, two-stage counter-rotating fan, which is able to deliver more than 20,000 pounds of thrust. The 3BSM is a swiveling jet pipe, which redirects the main engine thrust downward to provide the rear vertical lift. It can rotate 95 degrees in 2.5 seconds and directs 18,000 pounds of thrust. Aircraft roll control is achieved using two roll posts mounted in the wings of the F-35. These roll posts provide 1,950 pounds of thrust each (bypass thrust from F135 engine). In total, the Rolls-Royce LiftSystem provides 41,900 pounds of thrust.

The F135-PW-400 powers the Navy’s F-35C Carrier Variant (CV) and provides 28,000 pounds of thrust or as much as 43,000 pounds with afterburner.

The F135 is developed from the proven Pratt & Whitney F119-PW-100 engine which powers the U.S. Air Force F-22 Raptor. By the end of the development phase of the F135, the F119 had performed approximately 600,000 operational flying hours, thus providing a strong level of maturity and performance for the F135 program. By 2013, almost 21,000 test hours had been completed (17,700 ground + 2,950 flight). In December 2014, the worldwide F-35 fleet reached the 25,000 flight hour mark. The 50,000 hours flight hour milestone was surpassed in February 2016. Source fi-powerweb.com

On the F-35B, the engine is coupled with a shaft-driven lift fan system for STOVL propulsion. The counter-rotating lift fan, developed by Rolls-Royce Defence, can generate more than 20,000lb of thrust. Doors installed above and below the vertical fan open as the fin spins up to provide vertical lift.

      Jackson : if you read the two last DOT&E annual reports about F-35, you’d even consider write off any contract and even reclaim refunding by Lockheed as the plane is nowhere near to fulfil what Lockheed claims. As usual… Remember their advertising about F-104 which won the NATO competition (mostly through bribes) over Mirage-III. F-104 proved itself irrelevant in combat, Mirage-III ended being the #1 Mig-eater…
