- Very fast - avoids radar/detection - water based
My first assumption is that this is for stealth ops. "Rescue" doesn't need those features.
Fast and water based I can sort of see, but there's no point to it avoiding radar. The range of 180 miles (assuming I read that correctly) also makes it pretty pointless for search and rescue. You would have to know where someone is, the weather must be good enough to land on water, and they can't be more than 60 miles away.
A NH90 helicopter is faster, at 190mph (300km/h) and have longer range at 500 miles (800km). It also doesn't have to land to rescue someone.
Stealth and rescue can go hand and hand, no? I guess stating “rescue” still may bury the lead in that case.
TBF, You never know when you might need to sneak up on a shoreside compound, go in and “rescue” a bunch of people from their beds, and get back out undetected.
