I must admit that I thought this was an EH-101 Merlin / Cormorant and I was wondering why it was on the Sikorsky stand. It is actually a Sikorsky CH-148, as used by the Canadian Royal Navy. It is a navalised version of the civil Sikorsky S-92, which is in turn a civilian derivative of the S-70 Blackhawk series of helos. Of course the fact it was a twin when the Merlin is a triple should have alerted me. As at February, 2012, Canada has 28 of these helos on order, some have been delivered and the last are expected in 2014.
