[Block Suggestion]Solid fuel rocket engine

A rather simple block suggestion really, with 2 distinct uses I can think of.

The Idea is fairly self explanatory, an extremely powerful single use rocket engine with a limited burn time.

Going into a little more detail, the idea would be to add a thruster that would be fully fueled when built but which could not be re fueled. I'm suggesting it be a somewhat narrow, maybe only 1 block for a small one and 2x2 for a large one, but it would be long, say 5 block for a small one and 7 for a large one, the length would simulate the onboard fuel supply.

The purpose of such a thruster would be as follows, to be used in played made missiles and torpedoes which seem already quite popular but are often made either very bulky or very lacking in terms of thrust by the current solutions available in game. And to be used as solid fuel rocket engines in early game orbital ships in case a player wants to make a quick exit off of a planet and doesn't want to spend resources on a more long term shuttle. (A third use would be rocket assisted take off if wings with lift ever make it to the game, this again inspired by how such thrusters are used in real life.)

if you have ideas that extend upon this or can see obvious flaws with the idea, please let me know.
