This is what happens when there is too much centralization at the top. This is a cool technology that gets all the big wigs excited, but what possible use can it be? The article says to “protect the Northern Sea Route where infrastructure is weakly protected.”. Huh? Protect it against what? Aircraft Carriers? Submarines? How’s it going to do that? It’s a sitting duck.

In Russian double-speak, “protect the Northern Sea Route where infrastructure is weakly protected.” is code for "preparing to re-take Latvia, Estonia, and Lithuania. You DO remember Georgia and Ukraine, right?".

It is great Tech. Very efficient.

But it is also a fare weather craft They can not operate in rough weather.

Heavy seas will either drown the engines or wreck the propellers. Since the craft depends on ground effect for lift they can’t climb above the weather.

Fast invasion craft.

Like Nuclear powered aircraft. They developed all the technology needed to make them but there was no useful niche that matched their cost per flight hour. It turns out that no one needs a plane that can fly around the world 3 or 4 times without refueling (at the expense of payload).
