Company History
Founded 1994 in Falls Church, Virginia
Two separate companies, built by two separate men, merged in 1994 to form Northrop Grumman — but their histories run back to the dawn of American aviation. Jack Northrop founded Northrop Aircraft in Hawthorne, California, in 1939, after spending years at Douglas and Lockheed developing a specific obsession: the flying wing, an aircraft design that eliminated the fuselage entirely to achieve maximum aerodynamic efficiency. Northrop built flying wing prototypes in the 1940s. The Air Force rejected them. He dissolved the company, and the flying wing concept sat dormant for decades.
Leroy Grumman had a different obsession. Grumman Aircraft, founded in 1930 on Long Island, specialized in carrier-based naval aircraft — planes tough enough to survive catapult launches, arrested landings, and salt air corrosion. The F6F Hellcat, delivered to the Navy beginning in 1943, shot down more enemy aircraft than any other Allied fighter in the Pacific theater. The Apollo Lunar Module, delivered in 1969, was a Grumman product — a spacecraft designed to land on the Moon and return, manufactured with a precision that made the words "the Eagle has landed" possible.
The 1994 merger combined Northrop's aerospace design capability with Grumman's systems integration and naval aviation expertise. The B-2 Spirit stealth bomber, which Northrop had been developing since 1981, validated Jack Northrop's flying wing concept in the most consequential possible way: a production aircraft invisible to radar, capable of delivering nuclear or conventional weapons anywhere on earth from bases in the continental United States. The B-2 program also established the organizational capability for classified large-scale stealth manufacturing that made Northrop the only plausible bidder for the B-21 thirty years later.
Jack Northrop founded Northrop Aircraft, Incorporated in 1939 in Hawthorne, California, establishing the company that would eventually become half of Northrop Grumman. A self-taught aeronautical engineer of remarkable intuition, Northrop made his most lasting contributions through his obsession with the flying wing configuration — a design predicated on eliminating all aerodynamic drag unrelated to lift. His wartime company produced the P-61 Black Widow night fighter and the T-38 Talon trainer ancestor. His most ambitious projects — the YB-35 and YB-49 flying wing bombers — were cancelled by the Air Force in 1949, a decision Northrop believed was driven by pressure to merge with Consolidated Vultee rather than purely technical or financial judgment. The prototypes were ordered destroyed. Nearly three decades later, classified work at what had become Northrop Corporation produced the B-2 Spirit stealth bomber — a flying wing that vindicated every intuition Northrop had held. He was shown a rendering of the classified design in 1980, at age 85. He died the following year. His technical legacy lives in the B-2 and the B-21 Raider, both unmistakably his intellectual descendants.
Leroy Grumman co-founded Grumman Aircraft Engineering Corporation in 1930 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, robust 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 and tested by 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.
Leroy Grumman and partners established Grumman Aircraft Engineering Corporation in a Baldwin, Long Island garage. The company immediately began pursuing naval aircraft contracts, establishing a relationship with the U.S. Navy that would define it 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.
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.
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.
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.
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 unrivaled position in low-observable aircraft design.
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.
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.
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.
Northrop Grumman acquired Orbital ATK to create vertical integration across the space and missile propulsion supply chain, adding solid rocket motor manufacturing, small satellite production, and the Cygnus spacecraft to its portfolio.
Northrop Grumman acquired Litton Industries to gain world-class electronic warfare, navigation, and shipbuilding capabilities, diversifying beyond aircraft into the naval and electronic domains.
Northrop acquired TRW to gain space and satellite capabilities, missile defense systems, and automotive electronics (later divested). TRW's space division had built critical national security satellites for decades.
Northrop Corporation merged with Grumman to create the scale and diversification needed to compete in the post-Cold War defense industry consolidation wave, combining Northrop's stealth expertise with Grumman's naval aviation and electronics strengths.
Northrop Grumman was created on April 1, 1994 when Northrop Corporation acquired Grumman Corporation for approximately $2.1 billion, ending a hostile bidding contest with Martin Marietta. Northrop, founded in 1939 in Hawthorne, California by John Knudsen "Jack" Northrop, was a stealth- and flying-wing pioneer best known at the time as the prime contractor for the B-2 Spirit stealth bomber. Grumman, founded in 1930 in Bethpage, Long Island by Leroy Grumman, William Schwendler, and others, was a legendary Navy aircraft manufacturer responsible for the F4F Wildcat, F6F Hellcat, A-6 Intruder, F-14 Tomcat, and the Apollo Lunar Module — every crewed lunar landing used a Grumman-built lander. The 1994 combination was driven by post-Cold-War defense-budget consolidation: the US Department of Defense actively encouraged mergers via Secretary William Perry's 1993 "Last Supper" dinner with defense CEOs, and the surviving combined entity gained scale across military aircraft, electronics, and space systems that neither parent could have sustained alone. The merged company adopted the Northrop Grumman name and was headquartered initially in Los Angeles before later relocating to Falls Church, Virginia in 2011 to be closer to its primary customer in Washington.
Between 1996 and 2002 Northrop Grumman executed five transformational acquisitions that turned it from a $9 billion defense aerospace company into a $26 billion full-spectrum defense contractor. In 1996 it acquired Westinghouse's defense electronics business for $3.6 billion, gaining airborne radar and electronic-warfare capability. In 1997 it acquired Logicon, a defense-software and systems-integration firm, for $750 million. In April 2001 Northrop Grumman acquired Litton Industries for approximately $5.1 billion in cash and stock, gaining shipbuilding (Ingalls Shipbuilding in Pascagoula, Mississippi and Avondale Shipyard in Louisiana), electronics, and information systems. In November 2001 it acquired Newport News Shipbuilding for $2.6 billion, consolidating its position as the leading US Navy shipbuilder and gaining the nuclear-aircraft-carrier and nuclear-submarine construction franchise. In December 2002 it acquired TRW Inc. for $7.8 billion in stock, gaining the spy-satellite and ICBM-systems business that would become Northrop Grumman Space Systems. Together these deals built the modern Northrop Grumman portfolio: stealth aircraft, defense electronics, shipbuilding, ICBMs, and military space — a position no competitor occupied at comparable breadth.
On March 31, 2011 Northrop Grumman spun off its shipbuilding division as Huntington Ingalls Industries, distributing approximately 49 million shares of HII stock to Northrop Grumman shareholders. The spun-off entity included Newport News Shipbuilding (acquired 2001) and Ingalls Shipbuilding (acquired with Litton in 2001), making HII the largest US military shipbuilder with a market capitalization at separation of roughly $1.7 billion and revenue near $6.7 billion. The strategic rationale combined three threads. First, shipbuilding's capital structure differed materially from the rest of Northrop Grumman's business — it was capital-intensive with long contract cycles and lower margins than electronics or space, and the combined company's blended financial profile understated both businesses to public-market investors. Second, the 2010-2011 Avondale Shipyard closure in Louisiana created a wind-down liability that Northrop wanted to ring-fence. Third, Wes Bush, who became Northrop Grumman CEO in 2010, was pursuing a more focused portfolio strategy. The spin-off freed Northrop Grumman to focus on aerospace, electronics, and space, while HII became a pure-play military shipbuilder. HII has subsequently grown to roughly $11 billion in revenue with a market cap near $9 billion as of 2024, validating the strategic logic of the separation.
The B-21 Raider is the US Air Force's next-generation stealth bomber, designed to replace the B-1 Lancer and B-2 Spirit by the 2030s and eventually the B-52 Stratofortress. Northrop Grumman won the prime contract in October 2015 over a Boeing-Lockheed Martin team, in an award with a fixed-price-incentive structure that has subsequently weighed on margins. The Air Force has stated a planned procurement of at least 100 aircraft at an estimated $700 million per unit in FY2010 dollars, with total program value reasonably estimated at $200 billion-plus over the multi-decade life including development, production, and sustainment. The B-21 was publicly unveiled on December 2, 2022 at Northrop's Palmdale, California facility, with first flight in November 2023 and continued flight testing through 2024-2025. The program is central to Northrop Grumman for three reasons. First, it is the largest single defense program Northrop has won and provides multi-decade visibility on roughly 30% of the Aeronautics Systems segment's future revenue. Second, the fixed-price structure means production cost discipline will determine margin outcomes — Northrop has taken multi-hundred-million-dollar charges through 2023-2024 on B-21 cost growth. Third, it consolidates Northrop's position as the dominant US stealth-bomber prime, a designation that almost no other defense contractor can match.
On June 6, 2018 Northrop Grumman closed its acquisition of Orbital ATK for $7.8 billion in cash plus $1.4 billion of assumed debt — total transaction value approximately $9.2 billion. Orbital ATK was the merged 2015 entity combining Orbital Sciences (small satellites, launch vehicles, the Cygnus ISS resupply spacecraft) and Alliant Techsystems (solid rocket motors, missiles, ammunition). The acquisition created Northrop Grumman Innovation Systems, later renamed Northrop Grumman Space Systems following further reorganizations, and became one of Northrop's four operating segments alongside Aeronautics Systems, Defense Systems, and Mission Systems. The strategic rationale combined three elements. First, solid rocket motors — used in ICBMs, missile-defense interceptors, and the Space Launch System boosters — were becoming a supply-chain choke point, and Orbital ATK was one of only two US producers (Aerojet Rocketdyne being the other). Second, the small-satellite and space-systems business gave Northrop exposure to the growing commercial-space and government space-domain-awareness markets. Third, Northrop's existing satellite-bus and intelligence-satellite business gained launch-vehicle and propulsion vertical integration. The deal was approved by the FTC subject to a consent decree on solid-rocket-motor supply terms to competing missile primes. Space Systems contributed roughly $14 billion of Northrop's $41 billion revenue in 2024 and is the company's fastest-growing segment.
