The TlAB(Translocation Anti Bounce) is a short-to-medium ranged TNT Cannon with an adjustible arc functional in vanilla Minecraft.

NOTE: Pasting the ship will cause the projectiles dispensers to activate, causing bye bye to guns!

Translocation is a 1.10 bug where you could use a piston to pull entities(well TNT in this case) from the piston head's side to the other side. The gun howerver does not have TRUE translocation as that was fixed in 1.16(I think I'm wrong..), rather, a pseudo-translocation of sorts. This p. translocation forces the projectiles up into a pj chamber with the help of a piston extending and retracting.

The turret shell(if there is any) and barrels(if there are any) are both for aesthetic purposes, to cover up unsightly redstone(if there are), and for protection if the turret is shot at by another TNT cannon.
