The price for the 53K is a fantastic bargain, but I am surprised it is fantastically cheaper than the 60M:
July 13/11: The US DSCA announces [PDF] Thailand’s official request for 3 UH-60M Black Hawk Helicopters,... The estimated cost is $235 million.
That works out to $70+M a piece.
Make Sikorsky commit to that price and the US can avoid the S-92 Canadian fiasco.
