Yes, I am an HS guy. Like gatordev said the HH-60H is pretty much a stripped down F. It only has one door though. The other notable differences are it lacks ASW mission equipment, an internal AUX tank, but is equipped with a variety of aircraft survivability equipment and is wired for the FLIR/Hellfire system. Structurally, it is closer to the F (tail landing gear position, vibe absorbers, and main landing gear structure), but then again they are both Seahawks. However, the first 50 or so 60Ss are structurally closer to a Blackhawk.
