I guess the logic is there's a certain chance an engine goes to poo poo. If you have one engine that's your chance to lose the plane. If you have two then both would have to die. But if you do vtlo then losing either engine will kill your plane so you're much worse off than with just one. genericnick has issued a correction as of 10:35 on Apr 24, 2023 |

The more expansive the goals of the US military, the more resources are needed to be "used efficiently," to the point where you eventually create a monster like the F-35.

How about instead of VTOL they just fire the jets straight up using a rocket sled or rail gun and then the jets land in the water and they pick em up with a crane? Seems like that would allow you to make the jets a lot cheaper plus the idea of shooting out jets like they were munitions is funny.

Seems like that would allow you to make the jets a lot cheaper plus the idea of shooting out jets like they were munitions is funny. one of the earlier ideas for a VTOL aircraft was simply having it stand on its tail for take-off - you'd just blast the regular engines hard enough to make the plane take off like a rocket the problem was how do you land it

https://en.m.wikipedia.org/wiki/Zero-length_launch These could land again fine, but the whole idea was abandoned as complicated and outpaced by offensive weapons. Mat testing was much more dangerous landing, due to the forces involved in landing a plane on high friction mats.

The ones that landed at regular airfields could land fine. vertical landing and mat landings, not so much.

A lot of drones use that slingshot to launch. I think a big one can work. I think the Marine should just shut up and ask for a electronic upgrade of the harrier. Harrier is cool because Arnold used it to push cop car and kill brown people in True Lies. F35 is not cool because Bruce Willis killed one with a truck in Die Hard.

Idk how much I'm supposed to post about explosives ITT, but black powder is usually used in detonators, fuses, ignitors, fuse lighters etc . It's a low explosive, so not used for warheads but for other parts of the explosive train, booster charges, pyrotechnics and the like.
