Steer seems to be military vessels for USS - would war state help? Alas, not readily turning up any mission rewwars options while tootling in and around Archon Delaine territoryThermic alloys? As usual, signal sources (forgot which ones) or high level cargo missions - the ones where the competition sends assassins after you. After killing them, collect whatever they leave floating around.
And RES sites - combat aftermath can result in thermic alloys being part of the blown up ship.

it was why I went RESLo, but all low grade mats from the popped balloons - might have to step up a tier and see if I can still survive...
