To ask the Secretary of State for Defence pursuant to the answer of 2 April 2009, Official Report, column 1400W, to the hon. Member for Moray, on nuclear submarines, on what nuclear submarines the 21 medium scale fires were reported; what the location was of each such submarine at the time of the fire; and when each fire occurred.

Royal Navy submarines are operated to the highest possible safety standards. Personnel are rigorously trained to deal efficiently and effectively with all safety incidents.

Three fires requiring both ship and external resources are recorded as occurring on Royal Navy submarines since 1 January 1987. Details of these are provided in the following table:

In the same time period, there were 20 medium scale fires and details of these are provided in the following table.

For those incidents where the vessel was either 'alongside' or 'at sea', the exact location of the vessel is not recorded centrally.

On behalf of the Secretary of State for Defence, I have written to Angus Robertson to correct the previous statement made on this subject-2 April 2009, Hansard, column 1400W.
