AN/APG-81

The AN/APG-81 is an Active Electronically Scanned Array (AESA) designed by Northrop Grumman Electronic Systems for the F-35 Lightning II.

The Joint Strike Fighter AN/APG-81 AESA radar is a result of the US government's competition for the world's largest AESA acquisition contract. Westinghouse Electronic Systems (acquired by Northrop Grumman in 1996) and Hughes Aircraft (acquired by Raytheon in 1997) received contracts for the development of the Multifunction Integrated RF System/Multifunction Array (MIRFS/MFA) in February 1996. Lockheed Martin and Northrop Grumman were selected as the winners of the Joint Strike Fighter competition; The System Development and Demonstration (SDD) contract was announced on 26 October 2001.

The AN/APG-81 is a successor radar to the F-22's AN/APG-77. Over 3,000 AN/APG-81 AESA radars are expected to be ordered for the F-35, with production to run beyond 2035, and including large quantities of international orders. As of August 2007, 8 APG-81s have already been produced and delivered. The first three blocks of radar software have been developed, flight tested, and delivered ahead of schedule by the Northrop Grumman Corporation. Capabilities of the AN/APG-81 include the AN/APG-77's air-to-air modes plus advanced air-to-ground modes including high resolution mapping, multiple ground moving target detection and track, combat identification, electronic warfare, and ultra high bandwidth communications. The current F-22 production radar is the APG-77v1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities.[2]

In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1-11 airborne laboratory. Since then, the radar system has accumulated over 300 flight hours, maturing all five blocks of software. The first radar flight on Lockheed Martin's CATBird avionics test bed aircraft took place in November 2008. Announced on 6/22/10: The radar met and exceeded its performance objectives successfully tracking long-range targets as part of the first mission systems test flights of the F-35 Lightning II BF-4 aircraft.[3]

The AN/APG-81 team won the 2010 David Packard Excellence in Acquisition Award for performance against jammers.

The Lockheed Martin Sniper Advanced Targeting Pod (ATP), designated AN/AAQ-33 in U.S. Military Service, provides positive target identification, autonomous tracking, coordinate generation, and precise weapons guidance from extended standoff ranges. The Sniper ATP is used on the F-15E Strike Eagle, F-16 Fighting Falcon, A-10 Thunderbolt II aircraft, B-1 (Rod Pod), UK Harrier GR9,.[1] and Canadian CF-18 Hornet. [2] The Sniper ATP is in service with Norway, Oman, Poland, Singapore, Canada, Belgium, Turkey, Saudi Arabia[3] and the UK MoD.[4][5] In July 2007, Sniper ATP was acquired by Pakistan, making it the tenth country in the world to be in possession of the Sniper pod.[6] The Sniper ATP contains a laser designator and tracker for guiding laser-guided bombs. The pod also features a third-generation FLIR receiver and a CCD television camera. FLIR allows observation and tracking in low light / no light situations, while the CCD camera allows the same functions during day time operations.

A team of Lockheed Martin UK, BAE Systems and SELEX Galileo (formerly Selex S&AS) has successfully demonstrated and flown a Sniper ATP on board a Tornado GR4 combat aircraft.

The U.S. Air Force initial seven-year contract for Sniper ATP has potential value in excess of $843 million. The Sniper ATP has delivered over 125 pods and the U.S. Air Force plans to procure at least 522 Sniper ATPs.

PANTHER is the export equivalent to the Lockheed Martin Sniper Extended Range (XR) targeting pod.

Multifunction Advanced Data Link (MADL) is a future data waveform to provide secure data-linking technology between stealth aircraft. It began as a method to coordinate between F-35 aircraft (the Joint Strike Fighter), but HQ Air Combat Command wants to expand the capabiltiy to coordinate future USAF strike forces of all AF stealth aircraft, including the B-2, F-22, and unmanned systems. MADL is expected to provide needed throughput, latency, frequency-hopping and anti-jamming capability with phased Array Antenna Assemblies (AAAs) that send and receive tightly directed radio signals.[1]

The Office of the Undersecretary of Defense for Acquisition, Technology and Logistics directed the Air Force and Navy to integrate MADL among the F-22, F-35 and B-2, to one another and to the rest of network.

Helmet Mounted hud

The FA-70 need not be physically pointing at its target for weapons to be successful. This is possible because of sensors that can track and target a nearby aircraft from any orientation, provide the information to the pilot through his helmet (and therefore visible no matter which way they are looking), and provide the seeker-head of a missile with sufficient information. Recent missile types provide a much greater ability to pursue a target regardless of the launch orientation, called "High Off-Boresight" capability, although the speed and direction in which the munition is launched affect the effective range of the weapon. Sensors use combined radio frequency and infra red (SAIRST) to continually track nearby aircraft while the pilot's helmet-mounted display system (HMDS) displays and selects targets. The helmet system replaces the display suite-mounted head-up display used in earlier fighters.

the FA-70's systems provide the edge in the "observe, orient, decide, and act" OODA loop; stealth and advanced sensors aid in observation (while being difficult to observe), automated target tracking helps in orientation, sensor fusion simplifies decision making, and the aircraft's controls allow action against targets without having to look away from them.

The problems with the current Vision Systems International helmet mounted display led Lockheed Martin to issue a draft specification for proposals for an alternative on 1 March 2011.[199] The alternative system will be based on Anvis-9 night vision goggles. It will be supplied by BAE systems.[201] The BAE system does not include all the features of the VSI helmet and is currently intended only for use during the testing program. In 2011, Lockheed granted VSI a contract to fix the vibration, jitter, night-vision and sensor display problems in their helmet mounted display. The improved displays are expected to be delivered in third quarter of 2013

Helmet Mounted Sight

The Helmet Mounted Sight (HMS) or Display (HMD) is a relatively recent addition to the fighter cockpit. The first devices in this category emerged during the late seventies, as an aid to targeting second generation heatseeking missiles. Given the limitations of both sight and missile technology of that period, the HMS slipped into obscurity for several years, only to be resurrected with the advent of fourth generation heatseeking missiles (WVR AAMs). At this time the HMS and newer, more capable HMDs are seeing a resurgence in the marketplace and can now be expected to become a standard feature in the cockpit of any new build fighter aircraft.

The fundamental idea behind all HMD/HMS designs is that of using the pilot's Eyeball Mk.1 as a cueing device to direct a missile seeker at a target, to facilitate a rapid lock and missile shot. This was not a very strong requirement with second and third generation heatseeking missiles, since the capable Air Intercept (AI) radars which proliferated with the teen series (and teenski series) fighters typically had several dogfighting modes which were designed to rapidly acquire and track a target. The missile seekers were "slaved" to the antenna boresight, and thus once the radar locked on to the target the missile seekers would also lock very shortly thereafter. Each missile would be fed with an elevation and azimuth signal produced by the radar, and these signals would be used to steer the missile seeker direction relative to the airframe.

When the first fourth generation missiles appeared, the Soviet Vympel R-73 (AA-11 Archer) and shortly thereafter the Israeli Rafael Python 4, it was clearly apparent that with very large off boresight angles, typically in excess of 60 degrees of arc, the AI intercept radar would no longer be adequate. The reason was simple, in that most antennas could not be easily slewed to angles beyond about 60 degrees. Space under radomes was limited, radome designs not optimised for beam quality at large off-boresight angles, gimbal design limits and servomotor slew rates all contributed to this situation. Last but not least, the cost of retrofitting large numbers of radars would not be trivial. And with the latest fourth generation missiles, like the AIM-132 ASRAAM, the missile itself could be fired over the shoulder at targets in the aft hemisphere. Therefore the HMS idea was resurrected.

Fly-By-Light

The Fly-By-Light Advanced System Hardware (FLASH) program is developing and demonstrating dual use fly-by-light hardware for flight control systems on military and commercial aircraft. Under the transport aircraft portion of this program, we and our industry teammates are demonstrating two representative fly-by-light systems. These fly-by-light demonstrations include a ground demonstration of a partial primary flight control system and a flight demonstration of an aileron trim control system. This paper describes these and discusses the dual use fly-by-light hardware developed for transport aircraft as well as the associated FLASH program demonstrations.

Adaptive Camouflage

Lightweight optoelectronic systems built around advanced image sensors and display panels have been proposed for making selected objects appear nearly transparent and thus effectively invisible. These systems are denoted "adaptive camouflage" because unlike traditional camouflage, they would generate displays that would change in response to changing scenes and lighting conditions. Fa-70 use 3 Generation based off of snake skin design

Gloved Close-coupled canard

In the close-coupled canard, the foreplane is located just above and forward of the main wing. At high angles of attack the canard surface directs airflow downwards over the wing, reducing turbulence which results in reduced drag and increased lift

Pratt & Whitney YF220pw-200

Scram-LACE

Scramjet

are mechanically very similar to ramjets. Like a ramjet, they consist of an inlet, a combustor, and a nozzle. The primary difference between ramjets and scramjets is that scramjets do not slow the oncoming airflow to subsonic speeds for combustion, they use supersonic combustion instead. The name "scramjet" comes from "supersonic combusting ramjet." Since scramjets use supersonic combustion they can operate at speeds above Mach 6 where traditional ramjets are too inefficient. Another difference between ramjets and scramjets comes from how each type of engine compresses the oncoming air flow: while the inlet provides most of the compression for ramjets, the high speeds at which scramjets operate allow them to take advantage of the compression generated by shock waves, primarily oblique shocks.[20]

Very few scramjet engines have ever been built and flown. In May 2010 the Boeing X-51 set the endurance record for the longest scramjet burn at over 200 seconds.[21]

Precooled jets / LACE

Intake air is chilled to very low temperatures at inlet in a heat exchanger before passing through a ramjet and/or turbojet and/or rocket engine. Easily tested on ground. Very high thrust/weight ratios are possible (~14) together with good fuel efficiency over a wide range of airspeeds, Mach 0-5.5+; this combination of efficiencies may permit launching to orbit, single stage, or very rapid, very long distance intercontinental travel. Exists only at the lab prototyping stage. Examples include RB545, Reaction Engines SABRE, ATREX. Requires liquid hydrogen fuel which has very low density and requires heavily insulated tankage.

AN/AAQ-40

The Electro-optical Targeting System (EOTS) is an affordable, high-performance, lightweight, multi-functional system for precision air-to-air and air-to-surface targeting. The low-drag, stealthy EOTS is integrated into the Lightning II's fuselage with a durable sapphire window and is linked to the aircraft's integrated central computer through a high-speed fiber-optic interface.

The EOTS uses a staring mid-wave 3rd-generation forward-looking infrared that provides superior target detection and identification at greatly increased standoff ranges. EOTS also provides high-resolution imagery, automatic tracking, infrared search and track, laser designation and rangefinding and laser spot tracking. As the world’s first and only system that shares a Sniper Advanced Targeting Pod and IRST systems legacy, it provides high reliability and efficient two-level maintenance.

Internal mounted on Rotary Launcher Assembly

Each weapons bay is equipped with a rotary launcher and two bomb-rack assemblies. In tests, the FA-70 successfully released B-61 nuclear and mk84 conventional missiles an bombs from the rotary rocket launcher, and Aim-120 and aim 188 ADRAM conventional weapons from the missile an bomb racks. The B61-12 is an earth-penetrating nuclear bomb for use against deeply buried and hardened targets. The B61 is a strategic free-fall nuclear bomb.

In the close-coupled canard, the foreplane is located just above and forward of the main wing. At high angles of attack the canard surface directs airflow downwards over the wing, reducing turbulence which results in reduced drag and increased lift

Scram-LACE

Scramjet

are mechanically very similar to ramjets. Like a ramjet, they consist of an inlet, a combustor, and a nozzle. The primary difference between ramjets and scramjets is that scramjets do not slow the oncoming airflow to subsonic speeds for combustion, they use supersonic combustion instead. The name "scramjet" comes from "supersonic combusting ramjet." Since scramjets use supersonic combustion they can operate at speeds above Mach 6 where traditional ramjets are too inefficient. Another difference between ramjets and scramjets comes from how each type of engine compresses the oncoming air flow: while the inlet provides most of the compression for ramjets, the high speeds at which scramjets operate allow them to take advantage of the compression generated by shock waves, primarily oblique shocks.[20]

Very few scramjet engines have ever been built and flown. In May 2010 the Boeing X-51 set the endurance record for the longest scramjet burn at over 200 seconds.[21]

Precooled jets / LACE

Intake air is chilled to very low temperatures at inlet in a heat exchanger before passing through a ramjet and/or turbojet and/or rocket engine. Easily tested on ground. Very high thrust/weight ratios are possible (~14) together with good fuel efficiency over a wide range of airspeeds, Mach 0-5.5+; this combination of efficiencies may permit launching to orbit, single stage, or very rapid, very long distance intercontinental travel. Exists only at the lab prototyping stage. Examples include RB545, Reaction Engines SABRE, ATREX. Requires liquid hydrogen fuel which has very low density and requires heavily insulated tankage.

AN/AAQ-40

The Electro-optical Targeting System (EOTS) is an affordable, high-performance, lightweight, multi-functional system for precision air-to-air and air-to-surface targeting. The low-drag, stealthy EOTS is integrated into the Lightning II's fuselage with a durable sapphire window and is linked to the aircraft's integrated central computer through a high-speed fiber-optic interface.

The EOTS uses a staring mid-wave 3rd-generation forward-looking infrared that provides superior target detection and identification at greatly increased standoff ranges. EOTS also provides high-resolution imagery, automatic tracking, infrared search and track, laser designation and rangefinding and laser spot tracking. As the world’s first and only system that shares a Sniper Advanced Targeting Pod and IRST systems legacy, it provides high reliability and efficient two-level maintenance.

Internal mounted on Rotary Launcher Assembly

Each weapons bay is equipped with a rotary launcher and two bomb-rack assemblies. In tests, the FA-70 successfully released B-61 nuclear and mk84 conventional missiles an bombs from the rotary rocket launcher, and Aim-120 and aim 188 ADRAM conventional weapons from the missile an bomb racks. The B61-12 is an earth-penetrating nuclear bomb for use against deeply buried and hardened targets. The B61 is a strategic free-fall nuclear bomb.
