"Let us get it clear, again. Scotty's unit is a roll on - roll off unit. Stored in boxes when not in use. It is NOT per helicopter and NOT a mandatory fit on all refurbished or new helicopters that are ever built in the future. Understand what it is and how it works."
Your making a lot of assumptions like everyone else....
If the kit is needed then there would need to be at least one set of kit at each base. How many airforce bases do you think there are ST2, one?
I'd hazard a guess 20 alone for the Koreans alone based on one unit...each fleet may need upto X amount so even one is extremely conservative...
You do the math
The Korean order is also new manufacture so why wouldn't eurocopter use the latest and best kit in there new copters?
