Defence spending is not broken down by service. Instead, the MOD operates a system of delegated authority to top level budget (TLB) holders. Some are single service but several, for example, Defence Estates and the Chief of Joint Operations support all three services and their budgets are not broken down by service.
Information about spending by TLBs can be found in the Government's expenditure plans (GEP) 2006-07 to 2007-08, Ministry of Defence (Cmd 6822), as well as in the Ministry of Defence's 2005-06 annual report and accounts. This includes the fleet top level budget, which covers the main operating and personnel costs of the Royal Navy.
Spending plans for future years are being reviewed in the current departmental planning round, and will also be shaped by the outcome of the comprehensive spending review, which will set the defence budget from 2008-09 to 2010-11.
The Royal Navy will continue to be funded across a broad spectrum of capabilities that will enable the fleet to meet its operational and standing commitments.
