AN/AAQ-40 Electro-Optical Targeting System

Last updated

The AN/AAQ-40 Electro-Optical Targeting System (EOTS) is an electro-optical targeting system fielded onboard Lockheed Martin F-35 Lightning II. It is the world's first sensor that combines the functionalities of both forward-looking infrared and infrared search and track into one compact sensor with air-to-air and air-to-surface targeting capability. To preserve stealth, the sensor is mounted on F-35's fuselage with a durable sapphire window and is linked to the plane's integrated core processor through a high-speed fiber optic cable. [1]

The AGM-65 Maverick is an air-to-ground missile (AGM) designed for close air support. It is the most widely produced precision-guided missile in the Western world, and is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities.

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 air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor, are emerging as propulsion that will enable future medium-range missiles to maintain higher average speed across their engagement envelope.

Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology. The F-117 Nighthawk was the first operational aircraft specifically designed around stealth technology. Other examples of stealth aircraft include the B-2 Spirit, the B-21 Raider, the F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57.

<span class="mw-page-title-main">Fire-and-forget</span> Type of missile guidance

Fire-and-forget is a type of missile guidance which does not require further external intervention after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target. This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile is vulnerable to attack and unable to carry out other tasks.

The Agency for Defense Development (ADD) is the South Korean national agency for research and development in defense technology, funded by the Defense Acquisition Program Administration (DAPA). It was established in August 1970 under the banner of the self-reliable defense. Its purpose is contributing to enforcing the national defence, to improving the national R&D capacity, and to fostering the domestic defense industry. ADD focuses on core weapons systems and core technology development, and studies major weapons platforms in high-risk and non-economical fields, unmanned and advanced, and new weapon systems for the future.
