I don't understand how a fully loaded plane like that can have enough power to take off from the surface even in calm seas, never mind sea state 4.



"The new X-plane will be a large flying boat similar in size and capacity to the C-17.
The Defense Advanced Research Projects Agency is working on a new X-plane under the Liberty Lifter Seaplane Wing-in-Ground Effect full-scale demonstrator program. Two teams, General Atomics working with Maritime Applied Physics Corporation and Aurora Flight Sciences working with Gibbs & Cox and ReconCraft, have been selected to develop designs to create a long-range, low-cost X-Plane capable of seaborne strategic and tactical heavy lift, similar in size and capacity to the C-17 Globemaster III transport aircraft.

The aircraft needs to be able to takeoff and land in Sea State 4, operate efficiently at less than 100 feet above the surface for sustained on-water operation up to Sea State 5 (up to 13 ft wave height), fly out of ground effect at altitudes of up to 10,000 feet and transport huge payloads at speeds faster than current sea lift platforms. The ferry range required is greater than 6,500 nm, while the cargo capacity should be enough for two USMC Amphibious Combat Vehicles (ACV) or six twenty-foot container units."

AFSOC just stopped work on the MC-130J on floats.  Sometimes the juice just ain’t worth the squeeze. This was one of those times.

I want to believe The USA can and will do this, I'm a huge fan of large designs and amphibians as well as the amazing Akranoplan.
Unfortunately, this will be looked at and probably go through the preliminary desgn work only to come to a screeching halt once the money is gone.
An aircraft like this would be a game-changer in so many ways, it is too bad nobody has already built one like this.

I still think they should just buy US-2's and be done with that exercise.

The potential for this erkanoplane thing will be worth following, but I seriously doubt anything will come of it.

If there was any advantage, they would be everywhere already.  Flying at high altitude is much more efficient.

The C-130 float thing had a lot of basic problems to deal with. Like the floats putting it really high off the water and ridiculously high off the ground to actually use it for cargo stuff.

Not quite that simple. There are plenty of better ideas and concepts out there that don't exist yet. The objective here is to carry heavy weight at faster speeds than conventional sealift. It's competing with ships, not planes.

Why is "sea state 4" take off/landing capabilities even needed?

If you need to blow shit up in bad weather just send a C17 with a full Rapid Dragon Load out.

I knew this would be a wing-in-ground effect design before opening the thread.

They've been talking about these things for decades, but for some reason the design never made it off the ground.


Okay, I'll see myself out...

If planes can do the same job, it's competing with planes.  What can it do that a "conventional" plane can't?

Land in high seas. The Earth is 3/4's water. In theory, anyway.

DARPA is a Research Agency, i.e. there are no current plans to actually build anything, just see if a design can even be done. Yes, it's a lot of money for just a design, but figuring out if a thing can be built before you decide to build it is far better, and much cheaper,  than trying to build something and find out that lack of proper materials, physics etc prevents your new thing from even being built.

It's a seaborne C-17 with some out-of-ground effect capability. They'll use it for strategic and tactical matters when conventional aircraft are unavailable or impractical. These will be able to land at sea where traditional aircraft can't due to no airfields, airfields bombed out etc. It is intended to supplement and improve strategic and tactical sealift, not airlift.

That is a capability that has nothing to do with the ability to remain in ground effect.

ETA: Landing in high seas is easy.  Not sinking, then taking off again is the challenge.

So build a sea plane that's intended to fly.  The ground effect crap is silly.  The only advantage is slightly less drag.  Big deal.  Modern jet engines have so much power, it's not even much of an advantage.
