Volume 468: debated on Thursday 6 December 2007

To ask the Secretary of State for Defence how many months each Royal Navy attack submarine in service spent (a) on operations and (b) in maintenance in each year since 1997. (165880)

Following the definitions of operations and maintenance I set out in my letter to the hon. Member on 5 November, the number of months each Royal Navy attack submarine spent on both in each year since 1997 were as follows:
