About as much use as the Lynx as well!
AW are an Italian company and no-one should believe that 189 production would stay in the UK once the small run for SARH was complete. The AW contract for Algerian training has been closed down now at St Mawgan and any remaining training is probably going to be done in Algeria or Italy.
When an Italian company has the choice between keeping jobs in their own struggling economy and the only slightly better UK one - it should come as no surprise that they will go for the home fixture. A cycnic would say that Finmeccania only wanted Westlands as a conduit to easy government money in UK.
As a stretched 139, the 189 will bring little extra to the SAR party and no-one seems to be buying the 139 for SAR duties - certainly not 200 of them! They have just got the cabin wrong - again!
