BattleCorps had a few aerospace fighter centric stories. Off the top of my head, the list includes Pitcairn Star and Half of a Warrior.
WarShip centric BC stories include The Last Full Measure, The Theseus Knot and Stars in the Time of Dreaming, the latter being set aboard a dying WarShip.
Generally space/zero-g centric BC stories include Echoes in the Void and McKenna Station. Pirates of Penance and Sore Loser are BattleMech stories in space, set on a space station and a JumpShip, respectively.
25 Years of Art and Fiction included a good aerospace fighter story too but the name eludes me.
And for laughs I'll also mention And Then There Was The Time... from Shrapnel.
