Does that make them smaller? The special ops airframes (E+G) are the same as the slicks, only heavier with the extra gadgets. Granted, at night it's real nice to have a flir on the flight path vector and a terrain following radar with climb/dive cue. But in the day VMC there's no difference.
Quite frankly, they're more maneuverable than the H-53 (which is only slightly smaller). It's fairly irritating when you're flying the H-53 in formation with them. And on that note:
I'd like to nominate the MH-53J/M as the best helicopter in the museums.
It is too big for any ops but at least the Special ops guys fly it at Tree top or lower altitudes >> giving them the best chance for survival against anti aircraft weapons.
