The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant. GEM is produced by Northrop Grumman Space Systems. [1]
The Minotaur VI is a five-stage launch vehicle proposed by Northrop Grumman that, as of 2024, has not flown. Minotaur VI is based on the Minotaur IV+, adding a second SR-118 first stage to increase performance. [5] A further enhanced variant, Minotaur VI+, is also proposed for beyond low Earth orbit missions using an added Star 37FM sixth stage ...

The Federal Trade Commission (FTC) approved the acquisition with conditions on June 5, 2018, and on June 6, 2018, Orbital ATK was renamed Northrop Grumman Innovation Systems. [ 7 ] [ 8 ] With Northrop Grumman's reorganization of its divisions effective January 1, 2020, Northrop Grumman Innovation Systems was split, with most of the sector ...
Some of these tasks may be delegated or sub-contracted to other companies. For example, United Launch Alliance formally subcontracted the production of GEM solid rocket motors for their Delta II and Delta IV (Medium version) rockets to Alliant Techsystems. (Both vehicles are now retired.) [5] [6] An LSP does not necessarily build all the ...
Castor is a family of solid-fuel rocket stages and boosters built by Thiokol (now Northrop Grumman) and used on a variety of launch vehicles. [1] They were initially developed as the second-stage motor of the Scout rocket .
The TR-107 was a developmental rocket engine designed in 2002 by Northrop Grumman for the NASA and DoD-funded Space Launch Initiative (SLI). Operating on LOX/RP-1, the engine was throttleable and had a thrust of 4,900 kN (1,100,000 lbf) at a chamber pressure of 17.7 megapascals (177 bar), making it one of the most powerful engines ever constructed.
Antares (/ æ n ˈ t ɑː r iː z /), known during early development as Taurus II, is an American expendable medium-lift launch vehicle developed and built by Orbital Sciences Corporation (later Orbital ATK and Northrop Grumman) with financial support from NASA under the Commercial Orbital Transportation Services (COTS) program awarded in February 2008, alongside the company's automated cargo ...
