It’s obviously a great idea, but

(why has no one said this yet?)

Ackshually 🤓 - those things in the image of the A-4 that you flipped around are fuel tanks, not weapons.

The missile would have to cancel out the speed of the plane before achieving any meaningful acceleration.

To be fair, speed is relative. Imagine a plane flies at 500 km/h and is pursued by another plane at the same speed. If the first plane fires a rocket backwards that accelerates for a total of 200 km/h, then for an observer on the ground the rocket will still do 300 km/h, in the same direction as the planes. However, the guys in the second plane will see a rocket approaching them at 200 km/h.

Wind resistance, aerodynamics, etc. will have an impact, but it can work.

To be fair, speed is relative.

Sure, but the relevant speed up there is relative to the air around you. The missile will have a negative air speed at first, than accelerate to positive, briefly passing through 0 in between, which comes with weird consequences for lift and steering.

Thrust vectoring though

It’s against the standards set down in Strunk and White’s Elements of Dogfighting

Their rocket exhaust as they’re being fired would slow the planes down, rather than providing a boost

For the same reason, cars have exhaust on the rear so that they can go much faster forward than backward

Edit: /s since you apparently need it after every joke. I know that missiles aren’t really fired, they detach and then propel themselves. Also, anyone who’s ever idled their car on a flat surface knows that the exhaust thrust cannot even overcome rolling resistance.

The exhaust doesn’t propel a car forward

Let’s agree on that the effect is of negligible magnitude.

I’m going to start a meme crackpot theory.

Torque doesn’t exist.
Cars move because of the exhaust gasses.

“What about trucks with an exhaust that points up?” I hear you ask, well why are they always bent over at the top to point backwards?

Tractors that have an exhaust on the top use it to keep the tractor on the ground, otherwise the forces of dragging things would cause the tractor to float off the ground. But the exhaust is pointed backwards slightly, other wise it wouldn’t move. The small backwards pointing force explains why tractors are so slow.

Electric cars are CGI, and part of the conspiracy to hide the fact that torque doesn’t exist.

dutchkimble ,

My god, you’re onto something here. That must also be why we evolved with backward facing asses, to ease our walks when we fart. Ventilated seats in your car? They help channel your farts to add nitro boost to your car’s exhaust.

Fucking hell, the air vents in the dashboard are all blowing backwards against the direction of travel, too. We been living a lie.

I forgot you need “/s” after every joke, even in joke communities. It is a reference to this greentext:

anon drives a car

Let’s give anon the benefit of the doubt. Perhaps they’re an alien engineer from a planet that only knows rockets, disguised as a teenager to learn about our modes of transportation.

Yes, there is a short film with just about this plot

Successful_Try543 ,

OK. I didn’t know that one.

Successful_Try543 ,

The rockets would need to accelerate in the opposite direction of their initial motion, thus a lot more energy would be needed to reach design velocity. That makes it necessary to carry a lot more fuel for the propellant and thus, the rocket can carry less explosives. For some moment the rocket would also have zero velocity.

On the analogy with the car: The exhaust gases do not carry enough momentum to actually have a nonneglibile effect.

StereoTrespasser ,

For the same reason, cars have exhaust on the rear so that they can go much faster forward than backward

Where do people come up with this nonsense

ChaoticNeutralCzech ,

It’s a reference to the greentext I posted in another comment. I know it makes no sense.

Submarines used to have torpedo tubes in the back.
