Northrop Grumman is an American aerospace and defence manufacturer involved in crewed aircraft, uncrewed systems, aircraft structures and mission equipment. Its aviation work includes strike, reconnaissance, surveillance and naval aircraft, together with the sensors and support systems used to operate them. The combined name dates from Northrop's acquisition of Grumman in 1994.[1]AircraftNorthrop Grumman · northropgrumman.com · Accessed 2026-09-13Open source details[2]1994 annual report and Form 10-KNorthrop Grumman · investor.northropgrumman.com · Accessed 2026-09-13Open source details
Corporate formation
Northrop purchased Grumman's outstanding stock in April 1994 and changed its name to Northrop Grumman Corporation on 18 May. It also acquired the remaining interest in Vought Aircraft in August that year, having previously held a minority stake. The company's contemporary annual report records these as separate transactions. The 1994 combination therefore brought together established aircraft businesses; it did not mark the beginning of the underlying Northrop or Grumman design traditions.[2]1994 annual report and Form 10-KNorthrop Grumman · investor.northropgrumman.com · Accessed 2026-09-13Open source details
Strike aircraft
The B-2 Spirit is a major Northrop Grumman bomber programme. The company acted as prime contractor and has also provided upgrades, depot support, spare parts and weapons integration. The relationship continued after construction of the original aircraft, illustrating how a bomber programme can remain an industrial responsibility through decades of service. Northrop Grumman's broader strike work includes air-vehicle design, flight controls, vehicle management and survivability technologies.[2]1994 annual report and Form 10-KNorthrop Grumman · investor.northropgrumman.com · Accessed 2026-09-13Open source details[1]AircraftNorthrop Grumman · northropgrumman.com · Accessed 2026-09-13Open source details
Naval and uncrewed aviation
The company's naval aviation portfolio includes the E-2D Advanced Hawkeye and MQ-4C Triton, combining crewed airborne surveillance with uncrewed reconnaissance. Its historical naval lineage also includes Grumman's F-14 Tomcat. These different platforms show why “military aircraft” is a wider category than fighters alone: naval forces also require persistent sensing, command information and support for other aircraft and ships.[1]AircraftNorthrop Grumman · northropgrumman.com · Accessed 2026-09-13Open source details
Structures and mission systems
Northrop Grumman works as a supplier as well as a complete-aircraft manufacturer. The 1994 annual report documents Boeing 747 centre-fuselage deliveries, while the modern aircraft portfolio includes composite structures for commercial aviation. Its mission-equipment activities encompass radar, electronic warfare, navigation and integrated avionics. Logistics and modernisation work support existing platforms after delivery. An aircraft carrying equipment made by Northrop Grumman is therefore not necessarily a Northrop Grumman airframe; the original aircraft manufacturer, structural partners and mission-system suppliers can be different organisations.[2]1994 annual report and Form 10-KNorthrop Grumman · investor.northropgrumman.com · Accessed 2026-09-13Open source details[1]AircraftNorthrop Grumman · northropgrumman.com · Accessed 2026-09-13Open source details
