Oh, and forgive me if I'm wrong the EH101 (now AW101) was a result of a military requirement for an extended range helicopter to operate from the back of a ship and find Russian, sorry enemy, subs.
Not a modification from a civil aircraft.
I also under that is very good at finding subs, ask the Americans. They were pretty pissed off when they couldn't hid their fish.
True, it's had it's technical issues. But now it's a mature aircraft and with the correct support package not doing too badly in the role for which it was intend.
