The AN/AAQ-37 Electro-Optical Distributed Aperture System (EODAS) [1] is the first of a new generation of sensor systems being fielded on the Lockheed Martin F-35 Lightning II. DAS consists of six high-resolution infrared sensors mounted around the F-35's airframe in such a way as to provide unobstructed spherical (4π steradian) coverage and functions around the aircraft without any pilot input or aiming required. [2]
The DAS provides three basic categories of functions in every direction simultaneously: [3]
The F-35's DAS was flown in military operational exercises in 2011, [5] has demonstrated the ability to detect and track ballistic missiles to ranges exceeding 800 miles (1,300 km), [6] and has also demonstrated the ability to detect and track multiple small suborbital rockets simultaneously in flight. [7] The AN/AAQ-37 DAS is designed and produced by Northrop Grumman. The current sensors used in the system may have insufficient night acuity for pilots used to flying with night vision goggles (NVG), and are therefore augmented by an embedded NVG camera in the helmet. [8] A DAS test system has also been used to track tank gun firing, but this is "not an F-35 requirement". [9] The EODAS has been produced by Raytheon since 2018 after Northrop Grumman decided not to participate in a follow on competition. [10]
The AGM-88 HARM is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments.
The Lockheed AC-130 gunship is a heavily armed, long-endurance, ground-attack variant of the C-130 Hercules transport, fixed-wing aircraft. It carries a wide array of ground-attack weapons that are integrated with sophisticated sensors, navigation, and fire-control systems. Unlike other modern military fixed-wing aircraft, the AC-130 relies on visual targeting. Since its large profile and low operating altitudes around 7,000 feet make it an easy target, its close air support missions are usually flown at night.
The Lockheed Martin F-35 Lightning II is an American family of single-seat, 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-35 contractor, with principal partners Northrop Grumman and BAE Systems. The aircraft has three main variants: the conventional takeoff and landing (CTOL) F-35A, the short take-off and vertical-landing (STOVL) F-35B, and the carrier-based (CV/CATOBAR) F-35C.

With 95,000 employees and an annual revenue in excess of $30 billion, it is one of the world's largest weapons manufacturers and military technology providers. The firm ranks No. 101 on the 2022 Fortune 500 list of America's largest corporations.
LANTIRN is a combined navigation and targeting pod system for use on the United States Air Force fighter aircraft—the F-15E Strike Eagle and F-16 Fighting Falcon manufactured by Martin Marietta. LANTIRN significantly increases the combat effectiveness of these aircraft, allowing them to fly at low altitudes, at night and under-the-weather to attack ground targets with a variety of precision-guided weapons.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
Directional Infrared Counter Measures (DIRCM) are a class of anti-missile systems produced to protect aircraft from infrared homing missiles, primarily MANPADS and similar simple systems.
The AN/AAQ-28(V) Litening targeting pod is an advanced precision targeting pod system currently operational with a wide variety of aircraft worldwide. The research and development of the Litening was first undertaken by Rafael Advanced Defense Systems' Missiles Division in Israel, with subsequent completion of Litening I for use in the Israeli Air Force.
An infrared search and track (IRST) system is a method for detecting and tracking objects which give off infrared radiation, such as the infrared signatures of jet aircraft and helicopters.
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing missiles by confusing the missiles' infrared guidance system so that they miss their target. Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm. The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile.
The AN/APG-81 is an active electronically scanned array (AESA) fire-control radar system designed by Northrop Grumman Electronic Systems for the Lockheed Martin F-35 Lightning II.
The Space Tracking and Surveillance System was a pair of satellites developed by the United States Missile Defense Agency (MDA) to research the space-based detection and tracking of ballistic missiles. Data from STSS satellites could allow interceptors to engage incoming missiles earlier in flight than would be possible with other missile detection systems. The STSS program began in 2001, when the "SBIRS Low" program was transferred to MDA from the United States Air Force. In December 2002, SBIRS Low Research & Development was renamed Space Tracking and Surveillance System (STSS).
A helmet-mounted display (HMD) is a headworn device that uses displays and optics to project imagery and/or symbology to the eyes. It provides visual information to the user where head protection is required—-most notably in military aircraft. The display-optics assembly can be attached to a helmet or integrated into the design of the helmet. An HMD provides the pilot with situation awareness, an enhanced image of the scene, and in military applications cue weapons systems, to the direction their head is pointing. Applications which allow cuing of weapon systems are referred to as helmet-mounted sight and display (HMSD) or helmet-mounted sights (HMS).
A missile approach warningsystem (MAW) is part of the avionics package on some military aircraft. A sensor detects attacking missiles. Its automatic warning cues the pilot to make a defensive maneuver and deploy the available countermeasures to disrupt missile tracking.
The Estrella Warbirds Museum is an aviation museum dedicated to the restoration and preservation of military aircraft, vehicles, and memorabilia. The museum is located at Paso Robles Municipal Airport in central California and is named after Estrella Army Airfield. In July, 2009, the museum opened an automobile display featuring classic racing cars, The Woodland Auto Display.
The AN/SPY-6 is an active electronically scanned array 3D radar under development for the United States Navy (USN). It will provide integrated air and missile defense for Flight III Arleigh Burke-class destroyers. Variants are under development for retrofitting Flight IIA Arleigh Burkes and for installation aboard Constellation-class frigates, Gerald R. Ford-class aircraft carriers, America-class amphibious assault ships, and San Antonio-class amphibious transport docks.
The Ground-Based Interceptor (GBI) is the anti-ballistic missile component of the United States' Ground-Based Midcourse Defense (GMD) system.
In air and missile defense (AMD), the Integrated Air-and-Missile Defense system (IAMD) is an SMDC research program to augment the aging surface-to-air missile defense systems and to provide the United States Army with a low-cost, but effective complement to kinetic energy solutions to take out air threats. Brigade level higher energy lasers are used in truck mounted systems called HELMTT. At lower levels, the Army needs to develop interceptors that don't cost more than small, unmanned aircraft systems. In early research they have successfully used 5-kilowatt lasers on a Stryker combat vehicle. The Mobile Expeditionary High-Energy Laser (MEHEL) was used at MFIX at Fort Sill, Oklahoma, in the first half of April, 2017.
The United States Army Integrated Air and Missile Defense [IAMD] Battle Command System (IBCS) is a plug and fight network intended to let any defensive sensor feed its data to any available weapon system. The system is designed to shoot down short, medium, and intermediate range ballistic missiles in their terminal phase by intercepting with a hit-to-kill approach. IBCS has been developed since 2004, with the aim to replace Raytheon's Patriot missile (SAM) engagement control station (ECS), along with seven other forms of ABM defense command systems. In 2022, IBCS successfully completed initial operational test and evaluation (IOT&E), and was approved for full-rate production in 2023.
