The figures given for 2008 in all tables are for 1 January to 30 September 2008.
Time not accounted for under operations and maintenance in the tables includes periods of basic sea safety training, post refit trials, periods of extended leave and other duties (such as conducting synthetic training, ammunitioning, storing) undertaken while in port.
As I stated in my letter to the hon. Member on 5 November 2007, the figures provided are necessarily approximate because records held centrally do not always distinguish precisely between routine maintenance and other time spent alongside, since the two activities are often intermixed.
(2) how many days each attack submarine in service has spent at sea in each year since 2003;
(3) how many days each Type (a) 22 and (b) 23 frigate in service spent at sea in each year since 2003.
