Well, as a guy who works out of the back end of a Pavehawk I can tell you that it's not the optimum SAR bird. Hell, sikorsky didn't even approve the mods way back when it was aquired by some quick thinking USAF Helo drivers, when the powers that be were going to let CSAR die on the vine. A few Army H-60's were purchased and sent off for various Mods and the end of the evolution is what we have today. A high performance SAR helo that is built like a concrete reinforced S@$# House, but has no room in the ****** end to work out of, and needed internal Aux fuel tanks to have decent range. BTW, ESSS wasn't the answer since it limits maneuverability, gun azimuth, operations in and around the helo, and airspeed. Hell, ESSS wasn't even desogned to be used operationally. It was intended as a ferry system, but was simply morphed by operational units as the need to extend range became apparent. One of our old H-3/HH-60 drivers summed it up pretty good when he said "The HH-60 in CSAR is like taking a vacation drive in your Porsche with your wife and kids, maid, and family dog".
Now don't get me wrong, I loved the ole' H-3 but it was a pig at altitudes. I loved the room, tons o' gas, range and amphibious hull. But it was just to old. After seeing the -101 and working with some RAF folks that fly the Merlin I'm in favor of that becoming our new CSAR Helo in the USAF. I might add that's the view of almost everybody in the community.
Now I've worked out of MH-53J/M's and there pretty nice as well, but the MX types will tell you that they are maintenance intensive birds. Something like 11 hours of maintenance for every hour of flying time. BTW Riddle I heard the exact same thing about the Marine 53's as well. But the Big Iron is definately a nice bird to work out of.
The other thing to consider is that the -101 is already out on the streats being used operationally. Many of the bugs will have been identified and worked out before decision time for the HMX-1 or USAF future PR vehicle . I'd love for the government to keep Sikorsky in business, but I'm also an NCO and want the best gear for the mission and for my men (and women
).
