Well played, SAS, referencing a 2 year old document, itself referencing 3 year old data to come to its conclusions regarding the suitability of the V-22 in theater.
Meanwhile, in the real world, the V22 essentially "flew in the face" of the GAOs conclusions in its deployments since 2008, with 50,000 of the 100,000 fleet flight hours occuring in the last two years. So, I suppose lowest cost per seat mile, safest rotorcraft in Marine inventory, increased readiness rates, etc etc dont mean a thing if you want to continue to set up the historical strawman of past issues.
Might as well have thrown the baby out with the bathwater on the Blackhawk too, eh? As you may or may not recall, the first S-70 prototype 73-21650 crashed in 1976 with 14 people on board who luckily survived, only for the exact same airframe to crash again in 1978 in Stratford killing 4 sikorsky employees. That was an entirely conventional helicopter. And can we even count how many TR failures and horrific crashes there have been with the CH53 series? Just ask the Israelis.
And suppose you do eliminate the V22. Whats your alternative? The 53K? Which now has a unit cost of $55-65 million, itself already delayed? Its barely out of (a rather suspect) CDR. How is its success such a foregone conclusion?
