I don't really see any advantage that SH-60 has that SH-3 doesn't besides forcing "commonality" down the throat of the U.S. Navy. Unless UTTAS has some really badass hover performance or something I don't really see why you would use him over something like SH-3 for hunting subs since SH-3 is just so much bigger, i.e. more room for stores and electronics.
H/e I guess if HH-65 is n minutes faster than HH-52 then that is a really bigge improvement. Is it just not possible to make a relatively high speed amphibious helicopter or would it be better to use an amphibious jet plane instead of HH-52?
Super Frelon seems to be the fastest amphibious helicopter and he goes barely 150 mph.
My apologies. I assumed you were talking missions like coastal patrol since you used the name for the coast guard version of the HH-65 instead of the name AS565 Panther. When it comes to naval warfare, I would say that the ability for a helicopter to float is not really needed for anything other than heavy lift helicopters meant for deploying or receiving troops in boats which can just be done by hovering really low like a Chinook. For rescue missions, helicopters with rescue divers and small boats deployed from other ships are good enough if not better. There is really just no need sit on the water. For ASW activities, just attach a rope/cable to the sonar buoy like they do now.
As for the question on a size requirement for float helicopters, I think it is just a height and width stability issue. You just need to look at the ratio of width/length to height of ships and helicopters in pictures/videos and then remember that while the engine and all that are in the bottom of a ship, they are on the top of a helicopter which makes it a lot harder to stabilize as well. On top of that, aircraft are pretty small and top heavy compared to sea-worthy ships and will be in danger of flipping if the sea state is acting up even a little.
Nooo. I was asking about HH-65 vs. HH-52 for SAR and SH-3 vs. S-70 for ASW.
I sort of assume since SH-3 is bigger and therefore swoler than S-70 in lbs carried it is just better by default. Someone else brought up the point that S-70 probably fits into CG/DDG hangars while SH-3 was only (AFAIK) used in CVN hangars and the USN has an MH-53E squadron for mine-hunting, so maybe a modern SH-3 is an MH-53 with an ASW kit?
I also assume perhaps wrongly that AW101 is more or less a modern SH-3? In size anyway.
