No-one is going to defend the MoD's poor commercial nouse.
But, if you want to ensure that what a bidder claims as compliance with the contract specification is, in fact, compliance rather than smoke and mirrors or outright lies - then you need SMEs who know SAR operations and SAR aircraft capability inside out.
Sadly, caveat emptor was the watchword with the last SARH competition since believing everything the salesman said was a sure path to lack of operational capability.
