This mission will refuel all ships which are in orbit of the planet, to which this planet is friendly: your own ships, ships with matching friendly codes, and ships whom you have offered the planet level of alliance.
Ships are processed in Id order. It does not matter whether they are cloaked or not. This mission is particularly useful because it happens after movement but before combat. You can thus refuel a dry ship in order to have it fight anyway.
