Lord West of Spithead – 2016 Parliamentary Question to the Ministry of Defence

The below Parliamentary question was asked by Lord West of Spithead on 2016-01-11.

To ask Her Majesty’s Government, further to the Written Answer by Earl Howe on 8 December 2015 (HL4047), whether the build time of HMS Vanguard from beginning of whole boat construction to commissioning was six years 11 months; and, if so, why the first Vanguard replacement will take in excess of 14 years, as laid out in the Strategic Defence and Security Review.

Earl Howe

The Vanguard class were built at the end of an extensive period of UK submarine production. UK industrial capacity diminished following the subsequent 10 year gap in submarine building, which is a key factor in the Successor build schedule. Additionally, the Vanguard build duration, which was more than eight years in duration, did not include sea trials, which take several years. The dates for Successor reported in the Strategic Defence and Security Review do include that activity.
