The partnership developing DII is called the Atlas Consortium and is made up of DXC Technology (formerly EDS), Fujitsu, Airbus Defence and Space (formerly EADS Defence & Security) and CGI (formerly Logica). Starting in May 2016, MOD users of DII begin to migrate to the New Style of IT within the defence to be known as MODNET; again supported by ...
The consortium is tasked with developing Defence Information Infrastructure (DII) which is a secure military network for the MoD (United Kingdom's Ministry of Defence). [1] This is the largest, most complex information infrastructure rolled out in Europe and connects 300,000 users and 150,000 terminals in 2,000 MoD locations around the world.
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. The Atlas II was a direct evolution of the Atlas I , featuring longer first-stage tanks, higher-performing engines, and the option for strap-on solid rocket boosters.
On the Atlas IIAS configuration, MA-5A also featured attachment points for four Castor 4A solid rocket boosters. [1] [3] MA-5A was based on the design of the previous MA-5 stage, used on Atlas I. The main difference between the two designs was the replacement of the MA-5's two LR-89-7 engines with RS-56-OSAs. [4]
Atlas I was the last use of the classic Atlas design with three engines, a jettisonable booster section, and two vernier engines. While retaining most of those features, Atlas II replaced the verniers with a hydrazine roll control system.

GPS IIR-1 or GPS SVN-42 was the first Block IIR GPS satellite to be launched. It was to have been operated as part of the United States Air Force Global Positioning System.It was launched on 17 January 1997, and was destroyed 13 seconds into its flight due to a malfunction of the Delta II launch vehicle that was carrying it.

A second Atlas 2 was built in Manchester, and was installed at the Computer-Aided Design Centre on Madingley Road together with the Cambridge Titan supervisor. This machine, the last Atlas, was finally switched off on 21 December 1976. [5] A third Atlas 2 was ordered by the UK's Atomic Weapons Research Establishment (AWRE) at Aldermaston.
This is a list of launches made by the Atlas rocket family, derived from the SM-65 Atlas ICBM. The currently operational variant, Atlas V, has flown 81 consecutive missions without failure between October 2007 and January 2022. Due to the size of the list, it has been split by decade: List of Atlas launches (1957–1959)
