The point is to land and drop some dudes off not just fly around. If you can't do the landing thing when it matters then you have a flying boat that's bad at being a C-130.If a C130 can operate over oceans without needing to land in the water, then so can an amphibious C130 if the sea state is too high.
Until someone blows up your airfield or has it surveilled so you can't do anything sneaky. I'd imagine that being able to disperse the takeoffs and base of operations is part of the attraction to the idea.If truly amphibious no need to be tied to a tender. I am not prepared to propose a con ops, but I bet there are plenty of islands and conventional airports it could.operate from and have the range to get where it needs to go and splash in. Certainly no need for at sea tending. It is just a tactical airlifted with more landing options.
I thought you meant they might get stuck with no where to land if sea states unexpectedly were bad. Of course they would depart on a mission requiring a water landing knowing they couldn't land because of sea state.The point is to land and drop some dudes off not just fly around.

SAR seems to be what the countries that currently have large amphibs use them for. Although I'd be curious as to how often they can actually land. Sea State 3 is actually pretty restrictive and you can pretty easily find yourself outside of it in the open ocean. Depending on the sea state scale you use the wave heights are between 2-4' (ish, it varies) and wind speed is around 10kts. Which is pretty much every day in the open ocean. In the past large sea planes got around this by operating from protected atolls and anchorages like Midway. So if you're flying around in your amphib doing SAR I'd imagine in many cases you'd be restricted to dropping stuff or a landing that you don't takeoff after like the PBY that rescued the USS Indianapolis survivors.I thought you meant they might get stuck with no where to land if sea states unexpectedly were bad.

Outside of special ops, it would be a great SAR asset for both military and civilian. I did a few SAR flights in the P-3 where the best we could do was drop life rafts in the vicinity and hope the survivors could get to them while we looked for a ship (most like hours away at a minimum) to pick them up. USCG SAR C-130s and USAF SAR C-130s have the same problem although the USAF will put a PJ or 2 in the water to help.
I'm just sniping at the JCIDS process, but wasn't the lack of a supersonic, hovering, stealthy jet fighter a capability gap back in WWII? Imagine how fast we could have whupped up on the Axis with a few of those.The way it's supposed to work is that if a capability gap is identified in planning...

Instant transporters are a capability gap too. Although would they make a copy and delete the original, or actually move the atoms?
Regarding the C-130 Seaplane variant, we should convince some billionaire to fund the development and then use it to get to his private island chain. We can benefit from his non-recurrent R&D.
I feel like this idea died back in the early 60s with the P6M. I mean, who doesn't love a seaplane and maybe some seaplane tenders? But otherwise this just seems like AFSOC trying to figure out how to stay relevant in the Pacific in a way that doesn't involve boats.
I know Japan has a few amphibians with their US-2s. Are there any other countries that actively fly large amphibians?

Those Clippers have a rich history. The kind of story that makes you say "wow," the ditching of Pan Am Flight 6 halfway across the Pacific Ocean.

I also noted that the US-2 has a technical and corporate pedigree that goes back to Kawanishi and their flying boats from WWII. Which is worth noting that that level of corporate technical knowledge on the subject of large flying boats is long dead in the US so any new start big flying boat would take a fair amount of reinventing the wheel. Even if LM does have archival data from Martin that's only a piece of the puzzle as it's not the same as your grandma writing down her recipe for cookies.This really strikes me as a solution in search of a problem and a command reaching for more relevance against a particular target.
Instead of shoveling money into a new program they only have to look to the US-2's as a solution if they want. They are very expensive and seem to be more of a make work project than anything else, but they are an off the shelf solution that fits the bill for this 'bright' idea and the Japanese are looking for buyers as they can only make so many for themselves.
Fun fact, the manufacturer of the US-2 is ShinMaywa which is nothing more than a 'reorganized' and renamed Kawanishi, manufacturer of the H6K 'Mavis' and H8K 'Emily' flying boats of WWII.
As a SAR platform the modern flying boat is a pretty niche asset compared to helicopters and ships, and might not be worth the return on investment given how few rescues they could likely be used for.
