X-Battlecarrier before first completion
Kill 1000 transports.
Easiest way near the biginning of the game is at level a-4. Keep entering and destroy all transports (34 total). Game only allows 999 of each kill. At 999 transports, you will recieve an x-battlecarrier hull.
The only other way to get this hull is to pick up as an enemy weapon around c-4 to c-9 after completing the game once.
