B-28 survival is the central check. Improve Sith Marauder and Darth Malgus if their ships repeatedly collapse; no universal minimum relic level is asserted here.
Equip all six pilot mod slots and level the mods to 15; use six-dot mods where available. Ship contribution depends on mod level and dots, not on a Speed primary, set bonus or secondary stat.
Check ship and reinforcement ability upgrades. Pilot gear, relics and abilities also affect crewed ships; a pilotless ship cannot be improved by remodding a character.

Kill order

Keep B-28 alive with Fury's recovery. Early single-target attacks into Hound's Tooth avoid feeding its turn meter by hitting other ships.
Use the available sabotage abilities; choose B-28 for an ally-targeted recovery or Breach-immunity effect. Do not assume every version of the ability has the same targeting.
Call Sith Fighter first, then Mark VI. On Mark VI's own turn with more than 40 swarm stacks, use the basic to remove Hound's Tooth.
Finish Razor Crest and the exposed attackers. Delay debuff-dependent area attacks while Tenacity Up blocks their purpose; use the bridge takeover if it becomes available.
Bring Scimitar if another reinforcement is needed. A fighter wipe can win before a bridge takeover; preserve your surviving damage dealers instead of forcing one exact ending.

Restarts & further notes

B-28 and Fury fall before the first reinforcement can stabilize the battle, or Mark VI cannot reach a useful execution turn.
