In 2007 BAE Systems acquired Armor Holdings adding to the size of Land & Armaments significantly.

BAe's land systems business was RO Defence, a major manufacturer of explosives, ammunition and small arms.

[3] In March 2005, BAE Systems announced the $3.174 billion acquisition of United Defense Industries (UDI).

UDI manufactured combat vehicles, artillery systems, naval guns, missile launchers and precision guided munitions.

Land and Armaments has received regular contracts for the "reset" of Bradley armoured fighting vehicles.

[5] In September 2009 BAE lost a larger contract, the first stage of a multibillion-dollar follow-on order for up to 23,542 trucks as part of the Family of Medium Tactical Vehicles programme.

The former United Defense business, BAE's US Combat Systems produces fighting vehicle platforms and armaments.

It also has a 50/50 joint venture with Nexter (formerly GIAT), CTA International, which is located in Bourges, France.

Upon its creation on 2 January 1985, Royal Ordnance plc owned the twelve Royal Ordnance Factories (ROFs) that remained open, plus the Waltham Abbey South site, RSAF Enfield and three Agency Factories.

Several factors delayed the intended privatisation until 22 April 1987, when British Aerospace purchased the company.

These include the BROACH multi-stage warhead produced in partnership with Thales Missile Electronics and QinetiQ.

Examples include the Challenger 2 main battle tank and the CV90 infantry fighting vehicle family.
