Question to the Ministry of Defence:
To ask the Secretary of State for Defence, how many operational defects (a) HMS Daring, (b) HMS Dauntless, (c) HMS Diamond, (d) HMS Dragon, (e) HMS Defender and (f) HMS Duncan have reported in each of the last six years.
All complex systems suffer defects and require maintenance throughout their life, and warships are no exception. Operational Defects (OPDEFS) can vary in their categorisation and severity, covering minor ancillary components to major defects. The OPDEF process only applies to Ships in operational service, and I have therefore supplied the numbers for full years for Type 45 ships since their Commissioning.
TOTAL OPDEFS ON TYPE 45 SHIPS IN THE LAST SIX YEARS | ||||||
| 2010 | 2011 | 2012 | 2013 | 2014 | 2015 |
HMS Daring | NA | 186 | 184 | 278 | 163 | 156 |
HMS Dauntless | NA | NA | 239 | 244 | 262 | 150 |
HMS Diamond | NA | NA | 251 | 220 | 182 | 165 |
HMS Defender | NA | NA | 209 | 224 | 202 | 209 |
HMS Dragon | NA | NA | 260 | 268 | 235 | 124 |
HMS Duncan | NA | NA | NA | 168 | 181 | 241 |
We would not release more detailed information related to these figures as this would allow deductions to be made about a ship's capability and may affect operational security.
