Well, here's another one, then: the Ohka flying bomb.
It was kinda same idea as the Komet: a rocket propelled super-fast airplane... except it was pretty much a cruise missile. This time it didn't have a bomb attached to it. It WAS a bomb with wings.
Just like with the Tsurugi, the problems started in training. This thing was not designed to actually land, although you had to give trainees SOME time at the stick before sending them to their death, so eventually they have to land. So this one did get a landing skid. Just like the Komet, like I was saying. Also just like the Komet you'd try to "glide" it to land. It had a ridiculously high landing speed and, as I was saying, no engine at that point to help you correct if you didn't line up just right. Even the first test pilots died trying to land it. Not from peroxide like with the Komet, just sheer mechanical impact with the ground. You can imagine how it went for the poor conscripted kids being trained as kamikaze.
If you survived training, the problems just got worse. For a start because, as you'd expect from a rocket engine, it had VERY short range. About 20 nautical miles.
Needless to say, you couldn't just take off from Japan and make it even to Okinawa.
Solution 1: Let's put some on carriers. Which meant a carrier had to try to get very dangerously close to an enemy to launch these. Two carriers were lost that way, including the Shinano which I mentioned before, without actually managing to launch any. Both to submarines, but still, any carrier that got in range to actually launch it wouldn't have made it back,
Solution 2: let's load it under a medium bomber and have the bomber fly close enough to the enemy to launch it. Thing is, the whole thing was heavy, and made the bomber slow too. Combined with the short range, some hundreds of bomber pilots lost their lives trying to deliver this.
So just like the Kaiten, it tended to also get the craft carrying it killed.
And then it didn't actually do much. It sunk one US destroyer, damaged another beyond repair, and IIRC it also sunk a cargo ship. It hit a few more, and there were some near misses, but the next problem reared its head: coming at transonic speeds, it had an over-penetration problem. A few more hit a US vessel, went straight through and out the other side, and blew up at a safe distance.
There weren't that many hits though. In fact you could quite literally count them on your fingers.
And not just because of most getting shot down together with the bomber carrying them. You may have noticed the word "transonic" two paragraphs ago. Yeah, it came near the speed of sound in a dive. Something that wasn't tested either in training (you really couldn't recover and land safely if you went into that kinda dive) nor even in a wind tunnel. The problem is that the airspeed over the top of the wing could go from laminar to viscous, resulting in a massive drop in lift. The problem was only solved after the war, and is why so many post-war aircraft had back-swept or delta wings. The Ohka wings didn't have nearly enough sweep to solve it. (I think the version that actually saw use actually had no sweep.)
So just like with the Zero, an untrained kamikaze pilot would find that his airplane suddenly behaves very differently in a dive -- albeit in a very different way -- making the trajectory not exactly what one had planned.
But yeah, the impact it made on the US forces was negligible (though at least not zero like for the tsurugi) and it came at the expense of a LOT of bomber and their pilots being lost too, in addition to the unfortunate souls in the cockpit of it, and the countless kids it killed in training.
The US crews named it the Baka Bomb (Baka=idiot in Japanese), and that's really all you need to know as the short version
