Grumman Aircraft
The Grumman Aircraft Engineering Corporation, later Grumman Aerospace Corporation, was a 20th century American producer of military and civilian aircraft. Founded on December 6, 1929, by Leroy Grumman and his business partners, it merged in 1994 with Northrop Corporation to form Northrop Grumman.

Northrop Corporation
Northrop Corporation was an American aircraft manufacturer from its formation in 1939 until its 1994 merger with Grumman to form Northrop Grumman. The company is known for its development of the flying wing design, most successfully the B-2 Spirit stealth bomber.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 93-106, Cypress, CA, 2013. . History Jack Northrop founded three companies using his name. The first was the Avion Corporation in 1928, which was absorbed in 1929 by the United Aircraft and Transport Corporation as a subsidiary named "Northrop Aircraft Corporation" (and later became part of Boeing). The parent company moved its operations to Kansas in 1931, and so Northrop, along with Donald Wills Douglas Sr., Donald Douglas, established a "Northrop Corporation" located in El Segundo, California, which produced several successful designs, including the Northrop Gamma and Northrop Delta.

Grumman LLV
The Grumman Long Life Vehicle (LLV) is an American light transport truck model designed as a mail truck for the United States Postal Service, which has been its primary user since it first entered service in 1986, 39 years ago. It was also used by Canada Post. The LLV uses a chassis built by General Motors based on its Chevrolet S-10 Blazer, Chevrolet S-10 with an aluminum body built by Grumman. In 2021, after a long competition, the USPS announced it had awarded a $6 billion contract to Oshkosh Corporation, Oshkosh Defense to produce the Next Generation Delivery Vehicle, which will replace the LLV. In February 2023, the USPS announced the purchase of 9,250 each of stock Ford Transit#E-Transit, Ford E-Transit vans and Stellantis gasoline-powered vans. , the first custom NGDVs were scheduled to enter service in June 2024, nine months after the original October 2023 target date.

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is als ...

Grumman FF-1
The Grumman FF "Fifi" (company designation G-5) is an American biplane fighter aircraft operated by the United States Navy during the 1930s.Eden and Moeng 2002, p. 762. It was the first carrier aircraft with retractable landing gear.Winchester 2002, p. 21. It was produced under license in Canada and known as the Goblin in Canadian service and Delfín (English: "Dolphin") in Spanish service. Design and development The ''FF-1'' was Grumman’s first complete aircraft design for the US Navy. The Navy had asked Grumman if their retractable landing gear made for the O2U-1 Scout planes could be retrofitted to the Navy's Boeing F4B-1 fighters; instead Grumman proposed a new fighter design.Jordan, Corey C"Grumman's Ascendency: Chapter One" ''Planes and Pilots Of World War Two,'' 2000. Retrieved: 22 July 2011. The prototype ''XFF-1'' (serial number A8878) was built at Curtiss Field (later named Columbia Field), New York to a contract placed on 22 April 1931, first flying on 29 December of ...
