DII(F) is one of the largest information infrastructure programmes in Europe.

It will provide a computing infrastructure and services that will enable sharing of information and collaborative working to a variety of groups and individuals including those that currently have limited or no connectivity. Ultimately it will provide around 300,000 user accounts on approximately 150,000 terminals across about 2,000 MoD sites worldwide.

DII will be central to transforming the capability of the Armed Forces by providing Network Enabled Capability through a single network of information. It will extend into the operational arena, interface with battlespace systems and improve shared information between headquarters, battlefield support and the front line, allowing greater interoperability between the MoD and its allies.

DII is being delivered in Increments. Increment 1 will provide DII(F) to around 70,000 desktops and 200,000 user accounts. Increment 2 looks at Deployed services and services to the Above Secret environment. The service ranges geographically from the office environment in headquarters to forward deployed units anywhere in the world.
