Founding Story

Jack Northrop spent the 1940s pushing the "flying wing", a tailless bomber design. His YB-35 and YB-49 prototypes were cancelled in 1949. Decades later the same tailless shape proved well suited to stealth, and Northrop won the Advanced Technology Bomber contract in 1981 that produced the B-2 Spirit. Grumman, founded on Long Island in 1929, built Navy fighters such as the Hellcat and the Apollo Lunar Module. Northrop bought Grumman in 1994, combining the two lineages.

Jack Northrop

Co-founder 1939

Background

John Knudsen Northrop was born in Newark, New Jersey in 1895 and was largely self-taught in aeronautical engineering, having studied European technical literature while working as a draftsman and designer at early California aircraft companies including Douglas Aircraft and Lockheed. His obsession with the flying wing concept, an aircraft with no fuselage or tail, generating lift across the entire airframe, drove his entire professional career. He founded Northrop Aircraft in 1939 and spent the following decade pursuing the YB-35 and YB-49 flying wing bombers before the programs were cancelled by the Air Force in 1949 under circumstances that Northrop attributed to political interference. He died in 1981, one year after being shown a classified rendering of the B-2 Spirit, his vindication.

Role at Northrop Grumman Corporation

Jack Northrop (1895-1981) was a largely self-taught aircraft designer who worked at Douglas and Lockheed before founding Northrop Aircraft in Hawthorne, California, in 1939. He built the P-61 Black Widow night fighter in World War II and devoted much of his career to the flying wing, flying the YB-35 and YB-49 bombers before the Air Force cancelled them in 1949. In 1980, shortly before his death, he was shown a model of the then-classified B-2, the tailless stealth bomber that vindicated his design ideas. His company merged with Grumman in 1994 to form Northrop Grumman. Jack Northrop was born in 1895.

Leroy Grumman

Co-founder 1929

Background

Leroy Randle Grumman was born in Huntington, New York in 1895 and studied mechanical engineering at Cornell University before serving as a Navy pilot during World War I. He worked briefly at Loening Aeronautical Engineering before co-founding Grumman Aircraft Engineering Corporation in December 1929 with Leon Swirbul and several colleagues in a garage in Baldwin, Long Island. Grumman was an engineer's engineer, hands-on, methodical, and committed to building aircraft that could withstand the severe operating environment of carrier aviation. His company's reputation for reliability and structural toughness made it the Navy's preferred aircraft supplier for three decades.

Role at Northrop Grumman Corporation

Leroy Grumman co-founded Grumman Aircraft Engineering Corporation in December 1929 in Baldwin, Long Island, New York, establishing one of the most distinguished naval aircraft manufacturers in American history. A Cornell-trained mechanical engineer and World War I Navy pilot, Grumman built his company on the singular insight that carrier aircraft operated in one of the most demanding environments in aviation, they had to be fast enough to fight, strong enough to survive hard deck landings, and reliable enough to be maintained at sea with limited tools and personnel. The F4F Wildcat and F6F Hellcat produced by his company during World War II helped establish American air superiority in the Pacific. The Lunar Module, built by Grumman engineers, which carried the twelve astronauts who walked on the Moon, represents one of the most consequential engineering deliverables in human history. Grumman retired from active management in 1966 but remained associated with the company until his death in 1982. The company that bears his name merged with Northrop Corporation in 1994 to form Northrop Grumman, and its naval aviation heritage endures in the E-2D Advanced Hawkeye still produced today.

Education: Cornell University College of Engineering; Huntington High School. Leroy Grumman was born in 1895.

Kathy Warden

Chair, CEO & President

2019 – Present

CEO since January 2019 and chair since August 2019. Under Warden the B-21 Raider was unveiled (2022), flew (2023) and entered low-rate production, the James Webb Space Telescope launched (2021), and backlog grew to a record $95.7 billion at the end of 2025 and about $105 billion by mid-2026. Her tenure also includes the Sentinel cost breach and B-21 loss charges.

Wes Bush

Chairman & CEO

2010 – 2018

Moved headquarters from Los Angeles to Virginia and spun off shipbuilding as Huntington Ingalls Industries in 2011, won the Long Range Strike Bomber (B-21) contract in 2015, and acquired Orbital ATK in 2018.

Ronald Sugar

Chairman & CEO

2003 – 2010

Led the company after the Litton and TRW acquisitions, integrating them during the 2000s while the company carried large shipbuilding and IT services businesses.

Kent Kresa

Who Founded Northrop Grumman? FAQ

Who was Jack Northrop and what was his major vision for the 'Flying Wing'?

John Knudsen "Jack" Northrop (1895-1981) was an American aircraft designer who worked at Douglas and Lockheed before founding Northrop Aircraft in Hawthorne, California, in 1939. He championed the tailless "flying wing" (YB-35 and YB-49), a design approach later reflected in the B-2 Spirit.

Who was Leroy Grumman and how did he establish Grumman Aerospace in 1929?

Leroy Grumman (1895 to 1982) was an American aeronautical engineer, test pilot, and industrialist who on December 6, 1929, co-founded Grumman Aircraft Engineering Corporation in Baldwin, Long Island, New York, with Jake Swirbul and William Schwendler, building rugged naval aircraft nicknamed the 'Grumman Ironworks'.

What famous carrier-based fighter planes did Grumman build during World War II?

Grumman built the carrier-based fighter planes that won the air war in the Pacific: the F4F Wildcat, TBF Avenger torpedo bomber, and the well-known F6F Hellcat (which shot down 5,223 enemy aircraft, representing 75% of all US Navy aerial victories in WWII).

How did Grumman build the Apollo Lunar Module (LM) that landed astronauts on the Moon?

In November 1962, NASA selected Grumman as prime contractor to build the Apollo Lunar Module. Grumman engineered and built all 12 lunar landers in Bethpage, New York, successfully landing six Apollo crews on the Moon (including Apollo 11 in 1969) and serving as the life-saving 'lifeboat' for the crew of Apollo 13.

What was Jack Northrop's emotional reaction to seeing the B-2 Stealth Bomber before his death?

In April 1980, months before his death, the US military granted Jack Northrop top-secret clearance to view the classified scale model of the Northrop B-2 Spirit stealth bomber; viewing his beloved Flying Wing design vindicated by modern stealth physics, Northrop famously wrote: 'Now I know why God has kept me alive for 25 years.'

What was the well-known Grumman F-14 Tomcat and why is it celebrated in aviation history?

Engineered by Grumman in the early 1970s, the F-14 Tomcat was a carrier-based supersonic, twin-engine, variable-sweep wing fighter equipped with the AWG-9 radar and AIM-54 Phoenix long-range missiles, popularized globally as the star aircraft in the 1986 film 'Top Gun'.

What was the P-61 Black Widow built by Northrop in World War II?

Designed by Jack Northrop, the P-61 Black Widow was the first operational American military aircraft designed specifically to use radar to hunt enemy aircraft at night, featuring a twin-boom configuration and all-metal airframe.

What enduring founding values did Jack Northrop and Leroy Grumman pass on to the modern company?

Both founders built companies around demanding engineering: Northrop around unconventional aerodynamics, Grumman around rugged, reliable Navy aircraft. Those traits still show in the B-21 and the E-2D Hawkeye.
