The General Dynamics F-16 Fighting Falcon is a single-engine supersonic multirole fighter aircraft originally developed by General Dynamics (now Lockheed Martin) for the United States Air Force (USAF).
 Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft.
 Over 4,500 aircraft have been built since production was approved in 1976.
 Although no longer being purchased by the U.S. Air Force, improved versions are still being built for export customers.
 In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which in turn became part of Lockheed Martin after a 1995 merger with Martin Marietta.
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF).
 The result of the USAF's Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities.
 The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The 481st Tactical Fighter Training Squadron is an inactive United States Air Force fighter squadron.
 Its last assignment was with the 27th Tactical Fighter Wing, being stationed at Cannon AFB, New Mexico.
 It was inactivated on 8 July 1980.

The Northrop/McDonnell Douglas YF-23 was an American single-seat, twin-engine stealth fighter aircraft technology demonstrator designed for the United States Air Force (USAF).
 The design was a finalist in the USAF's Advanced Tactical Fighter (ATF) competition, battling the Lockheed YF-22 for a production contract.
 Two YF-23 prototypes were built, nicknamed "Black Widow II" and "Gray Ghost".
The Grand Prix was a line of automobiles produced by the Pontiac Division of General Motors from 1962 through 2002.
 First introduced as part of Pontiac's full-size car model offering for the 1962 model year, the marque varied repeatedly in size, luxury, and performance during its lifespan.
 Among the changes were positioning in the personal luxury car market segment and mid-size car offering from the 2nd generation to the 5th generation for the sedan and from the 2nd generation to the 6th generation from the coupe; it returned to a full-size car from the 6th generation to the 7th generation for the sedan, positioned below the larger Bonneville in Pontiac's model lineup.
The 205th Tactical Fighter Squadron (第205飛行隊 (dai-ni-byaku-go-hikoutai ) ) was a squadron of the 6th Air Wing of the Japan Air Self-Defense Force.
 It was based at Komatsu Air Base, in Ishikawa Prefecture, Japan.
 When the squadron disbanded it was equipped with Lockheed F-104J/DJ aircraft.
 It was replaced by the Mitsubishi F-15J-equipped 306th Tactical Fighter Squadron.
The 352d Tactical Fighter Squadron is an inactive United States Air Force fighter squadron.
 Its last assignment was with the 35th Tactical Fighter Wing at Phan Rang Air Base, South Vietnam, where it was inactivated on 31 July 1971.
The Lockheed/Boeing/General Dynamics YF-22 was an American single-seat, twin-engine fighter aircraft technology demonstrator designed for the United States Air Force (USAF).
 The design was a finalist in the USAF's Advanced Tactical Fighter competition, and two prototypes were built for the demonstration/validation phase of the competition.
 The YF-22 won the contest against the Northrop YF-23, and entered production as the Lockheed Martin F-22 Raptor.
 The YF-22 has similar aerodynamic layout and configuration as the F-22, but with differences in the position and design of the cockpit, tail fins and wings, and in internal structural layout.
A sixth-generation jet fighter is a conceptualized class of fighter aircraft design more advanced than the fifth-generation jet fighters that are currently in service in the United States and in development in other countries.
 The United States Air Force (USAF) and United States Navy (USN) are anticipated to field their first sixth-generation fighters in the 2025–30 time frame.
 The USAF is pursuing development and acquisition of a sixth-generation fighter through the F-X program to complement existing platforms in service such as the Lockheed Martin F-22 Raptor.
 The USN is pursuing a similar program called the Next Generation Air Dominance, likewise intended to complement and/or replace its existing aircraft such as the Boeing F/A-18E/F Super Hornet.

Question: What 5th generation USAF tactical fighter built by Lockheed Martin and Boeing will remain in service alongside the new sixth generation fighter?
Answer: Lockheed Martin F-22 Raptor
