Only one built, and it’s still on the shore of the Caspian sea:

There’s something to be said for the aesthetic of old Soviet technology. It feels almost surreal, like an engineer’s fever dream.
This is like the Endgame of hovercrafts lmao
I love it. It looks like it shouldn’t work, but it did and it did it well
It would be scary as shit to see this mf approaching
At 300 miles per hour top speed, I think you’ll just hear the jet engines and then either see a gray blur or die.
Unless you happen to be behind a decent sized hill, then you’ll just go deaf and wonder what the fuck that noise was. A 5 meter service ceiling is impressively low for a craft that is 19 meters tall.
I just found it funny they put service ceiling in the specs. Look at other aircraft
42,000m
38,000m

It is technically an aircraft.
I just can’t think of any use for this thing that an actual airplane or conventional truck couldn’t accomplish. A truck can transport equipment and personnel over long distances. And an airplane can provide much better close air support by overflying the enemy.
But giant hovercraft is really cool.
It was preliminary conceived as a platform for anti ship missiles. Because it was so low, it could get within 10 to 20 miles before showing up on ship based radar. Basically think of it as a ship but with the speed of an aircraft. When the Americans first photographed it with a satellite they called it the Caspian sea monster. They had no idea what it could do and were genuinely worried at first.
Ultimately it proved too hard to fly. It had to be hand flown with a vertical margin of error of just a meter or two.
I can’t imagine how sweaty my hands would be having to hand fly that monster over water.
One good gust of wind and now you’re trying to swim at 300 miles an hour
Yeah I was watching a video about these things a little bit ago. If I am remembering correctly in rough weather the pilots had to switch every 20-30 minutes due to exhaustion.
Was half the crew pilots?
It gets better fuel efficiency than an airplane and goes 5x faster than a truck. Essentially you’re sacrificing the ability to go high for a more efficient way of staying off the ground.
Iran uses modern tiny ones. Presumably they’re cheaper than helicoptors or planes that could carry a similar payload.
wow, could only fly a few meters above sea level, so anytime the water was choppy, this thing just… wouldn’t be able to fly. Such an odd design
It was probably developed to push the limits of ground effect, since it can provide such a great advantage to travel efficiency. Think min-maxing to find the meta in a new competitive game.
This and other older ekranoplanes were only used on the Caspian, Black and Baltic sea, where huge waves are rare.
This looks like something that would chase after Mel Gibson in a modded GT falcon.
Kind of reminds me of the Yamato from Star Blazers.
Choo choo!
Would be interesting to see how that thing would fare in a modern war. On the one hand, it can deliver a shit ton of missiles very quickly. On the other hand it has a radar echo like, well, nothing like it I guess, and it certainly flies slower than any missile.
I would guess that it would survive about as long as it would take a $200 fpv drone to collide with one of the engine arrays. Then nautical drones would do their thing to turn it into an artificial reef.
In flight it’s way faster than any FPV or naval drone.
Sure, in a dead heat and as long as there aren’t any big waves. Also, you do realize that it’s possible to attack this thing from other directions than directly behind it while it’s at full speed, right?
If you attack it head on you have a very short window of opportunity before it’s past you and if you try from the side you’ll have to be really really good at geometry. And that thing won’t go in a straight line while it’s in enemy range.

So, you have to be accurate. Like we’ve been doing for hundreds of years with projectiles, even non-guided ones. Check.

So… good like as in a computer doing the math? Check.

Bad news friend, they can’t turn for shit due to ground effect, and they can’t ascend or descend either. There’s a reason these things were immediately abandoned as a viable concept after only 3 years in operation and without seeing any combat.
Definitely thought this was AI at first.
