tube bomb

For guided munitions, it is possible to build tubes into aircraft from which bombs can be ejected; this provides a more streamlined aircraft with a smaller radar signature.

I can't remember where I read this but it was discarded after testing showed the bomb could follow in the slipstream for a long distance and not be dropped accurately.
