  Didn't someone do a very cheap KEAP missile according to the megatraveller
rules? It might have changed now of course. I'll put in a higher overhead for
the engine in the missiles, but then there has been an opening for solid
fuel missiles with a low amount of Gturns for close in work.

  Actually I imagined something more shotgun-like. All elements are fixed
mounted with minuscle differences in direction, and the entire missile is
pointed towards the target.

  Ok ok I've already corrected that.
