The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, supersonic stealth strike fighters. A multirole combat aircraft designed for both air superiority and strike missions, it also has 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.
Northrop Grumman Corporation is an American multinational aerospace and defense company. 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 ranked No. 101 on the 2022 Fortune 500 list of America's largest corporations.
The Northrop Grumman E-10 MC2A was planned as a multi-role military aircraft to replace the Boeing 707-based E-3 Sentry and E-8 Joint STARS, the Boeing 747-based E-4B, and the RC-135 Rivet Joint aircraft in US military service. The E-10 was based on the Boeing 767-400ER commercial airplane.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array 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).
The Medium Extended Air Defense System (MEADS) is a ground-mobile air and missile defense system intended to replace the Patriot missile system through a NATO-managed development. The program is a development of the United States, Germany and Italy.
Northrop Grumman Electronic Systems (NGES) was a business segment of Northrop Grumman from 1996 to 2015, until a reorganization on January 1 2016 merged other Northrop Grumman businesses into NGES to form a new segment called Mission Systems. NGES had originally been created by Northrop Grumman's acquisition of Westinghouse Electronic Systems Group in 1996. The Electronic Systems sector was a designer, developer, and manufacturer of a wide variety of advanced defense electronics and systems. The division had 120 locations worldwide, including 72 international offices, and approximately 24,000 employees; accounting for 20% of company sales in 2005.
The AN/APG-66 radar is an X-band solid state medium range pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83. This radar was employed in all domestic and export versions of the F-16A/B models throughout the production. Subsequent upgrades have been installed in many varying aircraft types including the U.S. Customs and Border Protection's C-550 Cessna Citation, US Navy P-3 Orion, and Piper PA-42 Cheyenne II's.
The AN/APG-63 and AN/APG-70 are a family of all-weather multimode radar systems designed by Hughes Aircraft for the F-15 Eagle air superiority fighter. These X band pulse-Doppler radar systems are designed for both air-air and air-ground missions; they are able to look up at high-flying targets and down at low-flying targets without being confused by ground clutter. The systems can detect and track aircraft and small high-speed targets at distances beyond visual range down to close range, and at altitudes down to treetop level. The radar feeds target information into the aircraft's central computer for effective weapons delivery. For close-in dogfights, the radar automatically acquires enemy aircraft and projects this information onto the cockpit head-up display. The name is assigned from the Army Navy Joint Electronics Type Designation System.
The AN/APG-68 radar is a long range Pulse-Doppler radar designed by Westinghouse to replace AN/APG-66 radar in the General Dynamics F-16 Fighting Falcon. The AN/APG-68 radar is now currently being replaced on US Air Force F-16C/D Block 40/42 and 50/52 by the AN/APG-83 AESA radar.
Active Phased Array Radar (APAR) is a shipborne active electronically scanned array multifunction 3D radar (MFR) developed and manufactured by Thales Nederland. The radar receiver modules are developed and built in the US by the Sanmina Corporation.
The AN/APG-77 is a multifunction low probability of intercept radar installed on the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition.
The AN/APG-80 is an Active Electronically Scanned Array (AESA) system designed and manufactured by Northrop Grumman for use on the Lockheed Martin F-16 Fighting Falcon fighter aircraft. It was originally designed to be included on the F-16C/D Block 60 Desert Falcon aircraft ordered by the United Arab Emirates, subsequently reclassified as the F-16E/F Block 60 Desert Falcons; first deliveries were made in 2003.
The Mitsubishi X-2 Shinshin is a Japanese experimental aircraft for testing advanced stealth fighter aircraft technologies. It is being developed by the Japanese Ministry of Defense Technical Research and Development Institute (TRDI) for research purposes. The main contractor of the project is Mitsubishi Heavy Industries. Many consider this aircraft to be Japan's first domestically made stealth fighter. ATD-X is an abbreviation for "Advanced Technology Demonstrator – X". The aircraft is widely known in Japan as Shinshin although the name itself is an early code name within the Japan Self-Defense Forces and is not officially in use. The aircraft's first flight was on 22 April 2016.
A large number of variants of the General Dynamics F-16 Fighting Falcon have been produced by General Dynamics, Lockheed Martin, and various licensed manufacturers. The details of the F-16 variants, along with major modification programs and derivative designs significantly influenced by the F-16, are described below.
A fifth-generation fighter is a jet fighter aircraft classification which includes major technologies developed during the first part of the 21st century. As of 2024, these are the most advanced fighters in operation. The characteristics of a fifth-generation fighter are not universally agreed upon, and not every fifth-generation type necessarily has them all; however, they typically include stealth, low-probability-of-intercept radar (LPIR), agile airframes with supercruise performance, advanced avionics features, and highly integrated computer systems capable of networking with other elements within the battlespace for situational awareness and C3 (command, control and communications) capabilities.
The AN/APG-83 Scalable Agile Beam Radar (SABR) is a full-performance active electronically scanned array (AESA) fire control radar for the General Dynamics F-16 Fighting Falcon and other aircraft developed by Northrop Grumman. In a 2013 competition, Lockheed Martin selected SABR as the AESA radar for the F-16 modernization and update programs of the United States Air Force and Republic of China Air Force.
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 Next Generation Jammer is a program to develop an airborne electronic warfare system, as a replacement for the AN/ALQ-99 found on the EA-18G Growler military aircraft. It reached Initial Operating Capability in 2021.
The AN/APG-85 is an active electronically scanned array (AESA) radar system designed by Northrop Grumman for the Lockheed Martin F-35 Lightning II. The AN/APG-85 is a further development of the AN/APG-81 and is planned to be installed in all three variants of the F-35 aircraft from Lot 17 and onwards, which are planned to enter production in 2025.
