weapon platforms

[Barnacle Bill]

There is another way - "lend-lease". Load them up on some old clunker of a transport and give the ship as a gift to a weak & technologically backwards AI (like maybe a neutral). The obsolete WP's (or any other cargo on board when the AI accepts the gift) go to the AI as well. You get brownie points for giving them a gift, and your old junk is off your hands. The superpowers do this in real life.
