We must not forget that it is only the RAF element of SAR that is being lost. The RN FAA will continue conducting SAROPS using their helos albeit not part of the UK DofT system. SAR is a secondary role for the FAA and I expect we will still see awards being won by RN crews much as they did this year.
Any linkage between CSAR and SAR was an RAF concoction to save the RAF SARF last decade....it was transparent and disregarded by most sensible people.
