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.
Founders
Jack Northrop
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
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.
Key Milestones
Grumman Aircraft Founded
Leroy Grumman and partners founded Grumman Aircraft Engineering Corporation on Long Island in December 1929 and soon began building aircraft for the U.S. Navy, a relationship that defined the company for decades.

Jack Northrop established Northrop Aircraft, Incorporated in Hawthorne, California. From the outset the company pursued advanced aerodynamic designs, including the flying wing concept that would become Northrop's defining technical obsession and ultimate legacy.
Source: en.wikipedia.orgF6F Hellcat Enters Service
Grumman's F6F Hellcat carrier fighter entered operational service with the U.S. Navy and quickly established dominance over Japanese aircraft in the Pacific. The Hellcat achieved a kill ratio exceeding 19 to 1 and is credited by naval historians as the decisive factor in establishing American air superiority over the Pacific theater.

On July 20, 1969, the Grumman-built Lunar Module Eagle carried Neil Armstrong and Buzz Aldrin from lunar orbit to the surface of the Moon. Grumman would go on to build the Lunar Module for all six successful Apollo Moon landings, one of the most consequential engineering achievements in history.
Source: en.wikipedia.orgB-2 Spirit Program Initiated
Northrop Corporation won the Advanced Technology Bomber competition, securing the contract to develop what would become the B-2 Spirit stealth bomber. The selection validated Jack Northrop's flying wing philosophy three decades after he had been forced to scrap his YB-49 prototypes.
Source: en.wikipedia.orgNorthrop Acquires Grumman
Northrop Corporation completed its acquisition of Grumman Corporation for approximately $2.1 billion, forming Northrop Grumman Corporation. The merger created a defense contractor of sufficient scale to compete for the largest Pentagon programs in a consolidating industry.
Source: en.wikipedia.orgB-2 Spirit Enters Service
The B-2 Spirit stealth bomber achieved initial operational capability with the U.S. Air Force's 509th Bomb Wing at Whiteman Air Force Base, Missouri. The aircraft represented the culmination of Northrop's flying wing vision and established the company's position in low-observable aircraft design.
Source: en.wikipedia.orgTRW Space and Electronics Acquired
Northrop Grumman completed the $7.8 billion acquisition of TRW's space and electronics businesses, adding satellite manufacturing, space electronics, and ballistic missile defense capabilities. This acquisition created the foundation of what is now the Space Systems segment.
Source: en.wikipedia.orgHuntington Ingalls Industries Spun Off
Northrop Grumman completed the spinoff of its shipbuilding operations Newport News Shipbuilding and Ingalls Shipbuilding as independent publicly traded company Huntington Ingalls Industries. The divestiture sharpened Northrop's focus on higher-technology, higher-margin programs and significantly improved return on invested capital.
Source: en.wikipedia.orgOrbital ATK Acquired for $9.2 Billion
Northrop Grumman completed its acquisition of Orbital ATK, a manufacturer of solid rocket motors, small satellites, and the Cygnus commercial cargo spacecraft, for $9.2 billion. The acquisition created a vertically integrated space and propulsion enterprise and made Space Systems the company's largest revenue segment.

The James Webb Space Telescope, for which Northrop Grumman built the optical telescope element and the tennis-court-sized deployable sunshield, launched from Kourou, French Guiana on December 25, 2021. The successful multi-week deployment sequence validated one of the most technically demanding single deliverables in the company's history.

Northrop Grumman unveiled the B-21 Raider stealth bomber at its Palmdale, California production facility on December 2, 2022, the first public appearance of the aircraft. The B-21's first flight followed in November 2023, marking the formal beginning of the flight test program that would lead to production certification.
Source: en.wikipedia.orgSentinel Nunn-McCurdy Breach
The Pentagon reported a critical Nunn-McCurdy cost breach on the Sentinel ICBM and, in July 2024, certified the program to continue under a restructure, with an estimated cost of about $141 billion.
