The Seahawks were such a mess of a project that HdeH walked away and gave it all back to those idiots at Sikorsky.
Defence purchasing seems to be administered by complete morons, or political hacks, or both.
I still remember a marine engineer colleagues disbelief when we discovered (after the fire) that flexible fuel injection lines were fitted to Westralia.
He explained that the steel lines always fatigue because of the pressure pulses produced by the injector pumps. Sulzers solution is to use double walled steel lines with pressure gauges fitted to the cavity between.
When pressure appears on the gauge it indicates that the inner line has cracked and you have a decent interval of still safe operation to purchase a new assembly. His language about the flexible lines was unprintable.
