The AN/AAQ-37 Electro-optical Distributed Aperture System (DAS) is the first of a new generation of sensor systems being fielded on the Lockheed Martin F-35 Lightning II Joint Strike Fighter. 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. [1]

The DAS provides three basic categories of functions in every direction simultaneously: [2]

The F-35's DAS was flown in military operational exercises in 2011, [4] has demonstrated the ability to detect and track ballistic missiles to ranges exceeding 800 miles (1,300 km), [5] and has also demonstrated the ability to detect and track multiple small suborbital rockets simultaneously in flight. [6] 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. [7] A DAS test system has also been used to track tank gun firing, but this is "not an F-35 requirement". [8]

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.

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) radar system designed by Northrop Grumman Electronic Systems for the Lockheed Martin F-35 Lightning II.

The Space Tracking and Surveillance System (STSS) 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 device used in aircraft to project information to the pilot's eyes. Its scope is similar to that of head-up displays (HUD) on an aircrew's visor or reticle. 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).

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.
