Actually the ideal would be a helo equivalent to the Japanese Kilo. That would cover the HSM and HSC worlds with 1 model. Completely plug-and-play configurable depending on the mission. A removable sonar transducer mounted in the transition section, (as opposed to taking up space in the cabin), cabin that can be configured for any mission with seats that swap out in 2 seconds, ability to swap out copilots in flight, all digital cockpit, automatic approach that is capable of flying the helo down to the deck of a smallboy, PC cards that keep tabs on the systems so if there is an issue you take the card to maintenance to be read, moving map, better engines and more efficient rotors, etc, etc.
Political moves kept any sort of decent movable map out of the Sierra, took away the refueling probe option, better weapons and foward firing guns, etc. Heck they even had to figure out how to remanufacture the sonobouy launchers from the Bravo for the Romeo, and those were one of the stupidest ideas ever. Talk about wasted man-hours. It would be nice to see the platforms that the communities need, actually being produced. Unfortunately though, the Army went through alot trying to get what they wanted, but at least they finally got most of it.
