During this phase you can share your known ship designs (either those you created or those salvaged from other ships) with any other empire with whom you are in message contact.  The recipient(s) will receive the designs immediately and will be able to build ships of those classes on the same turn.

Allies: Alled empires always share any designs salvaged on this turn.  New ship designs created by your empire are not shared with your allies automatically; you must share them explicitly.
