I think the S-92 has to be in front, look at whats happening now in the North Sea area: the first CHC SAR S-92 is in production/fitout now -so you will have commonality in SAR types, NORSK is the high time user in the world based in Sola/Stavanger, CHC/HS also based at Sola/Stavangar have a large S-92 fleet and the headquarters of 330 skn (the SAR Sqn) is at Sola/Stavanger, all that experience,expertice and facilities in one place why choose something else!!!
But why use logic, the politicians don't!!
Just look at Australia, Logic and most people in the Military wanted UH-60M's and Apache's but noooooo the poli's chose the Tiger and NH90.
