That, or something similar, has been around conceptually since the 60's or early 70's. It is one of several concepts my dad priced for the DOD numerous times over his 30+ years at Lockheed Georgia, knowing that the DOD wasn't ever gonna order it... Lotsa wasted money trying to put numbers to the DOD's wish list.

This is what I came up with today on the AFSOC C-130J that showed up in my Aviation Week Online Daily Briefing and earlier related concepts.

Why not just buy (or have Lockheed-Martin license-build) some of these?

Here are my thoughts:

1. I doubt there is a budget to do this.

2. I would be curious to understand the missions the US can't currently do that SOCOM believes could be accomplished with a nautical Herk.

3. Infrastructure? The Herk typically carries palletized or rolling cargo handled by forklifts or K-loaders. How does DoD plan to do that on water?

4. Depending on mission requirements, the Japanese US-2 looks like a feasible alternative. Wikipedia says it carries 20 pax or 12 stretchers. The Herk, IIRC, is 96/72. US-2 gross takeoff weight is listed as 105,000, the Herk (peacetime) is 155,000.

5. See #1.

Great idea. Unfortunately, the DOD almost never buys something "off the shelf". They customize and upgrade it to meet their spec's, which adds a huge layer of cost and makes anything (even things that appear reasonable on the surface) cost an unreasonable amount. Now, a spec-op's amphib would certainly need a new avionics suite and defensive measures, but the history of the DOD shows it would probably need to have new engines, a span reduction or increase (whichever is more expensive) and 14 other changes.

For reference, see the Slingsby T-3A trainer. A simple and effective piston trainer for the Brits, but we took it, upgraded the engine, and it ended up so screwed up we scrapped the whole fleet...

My guess is that they are wanting this capability for the same military reasons as the Japanese have their flying boats. It would make sense to buy from the Japanese or better yet, buy up a couple dozen HU-16's and remanufacture them with Turbo-Prop engines. The HU-16 has once of the best hull designs and was the ultimate Grumman seaplane. When you take something like the C-130 and say, put it on floats, think about how long the takeoff run would be on water at gross weight. it would have very limited applications.

I like the model of the Hercules "boat" but I expect all it would do is sink as soon as you unsealed the ramp! I love the Herc and flew them for years, but I don't think you'll ever see one in the water like those drawings and model. Cool model though, whoever kitbashed that.

Bit smaller but easy to modify and flown by many countries around the world.

I note in the latest rendering of our floaty-Herk the inner sides of the floats appear flat. Perhaps they telescope in to from a single unit under the fuselage to reduce drag a bit while in transit?

Or maybe they can go up the sides of the fuselage allowing conventional wheels and ramp for hard surfaces? The nose mount does not seem to support that, but found it interesting with the flat inner surfaces.
