The limited partnership became effective in January 1994 after FMC and Harsco combined major defense operations at a time when U.S. tracked-combat-vehicle procurement had fallen sharply. GAO reported that the combination created one of the largest U.S. manufacturers of armored tracked combat vehicles and that United Defense then consolidated final assembly and test work from California toward Pennsylvania.
In 1997, an investment group led by The Carlyle Group acquired the partnership interests from FMC and Harsco through Iron Horse Investors. United Defense's 2000 Form 10-K described the company as a supplier of tracked armored combat vehicles and weapons-delivery systems to the U.S. Department of Defense and allied militaries, with Bradley production and derivatives, Crusader artillery development, M88 recovery vehicles, M113 armored personnel carriers, and Mk45 naval guns among long-running programs.
The United Defense name later moved through United Defense Industries and into BAE Systems. A March 2005 United Defense release announced a definitive agreement for BAE Systems North America to acquire United Defense, and BAE Systems' 2005 annual report said the acquisition helped establish a global land-systems business covering armored combat vehicles, naval guns, missile launchers, canisters, artillery systems, and intelligent munitions.
