Sounds like you already have an established opinion and history with the subject matter...
Firstly, the "half the cost" label is dubious. The current fleet of C-2A aircraft were built in the mid 1980s @ $38 million each. Thats right around $80 million in today's dollars. And that is not to mention whatsoever how much the propsed modernized C-2 concept will cost, with upgraded 427A Rolls engine from the E-2D (along with a bunch of other E-2D systems, none of which are for free).
And yes, as with any rotorcraft, a gearbox failure is going to be a very rare event and probably a bad day.
In the end, the argument is whether or not you want the ability to replenish
anything outside of a full deck supercarrier.
Mr Danger.....you wouldnt have any relation to the infamous Carlton Meyer, who often posts on internet message/comment boards under the moniker Carlos and is from SoCal...do you?
