Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 15 December 2017 to Question 118343, how many incidents in which an RN submarine was damaged and where another vessel was not involved, there have been by (a) class of submarine and (b) severity of damage to the boat in the last five years.

The only incident in which a Royal Navy submarine was damaged, and where another vessel was not involved, in the last five years was in November 2014 when HMS TALENT was hit by floating ice while deployed. HMS TALENT suffered damage to her conning tower in this incident but all systems remained fully functional, there were no nuclear concerns, and the vessel was able to return to Devonport Naval Base under her own power.
