Warships Can Actually Be Built Like This

Warship design, manufacturing, and sales + Terra + farming + Eve + 40k + Lagrange + Star Wars + Angels

Development direction: Transport - Destroyer - Cruiser - Aircraft Carrier - Battleship - Titan - Megaship (some other ships may be added along the way, such as carrier-based aircraft).

Reference warships: Lagrange + 40k + Eve, etc.

The combat mode is 40k. If you can't accept that or want to see some awesome space battles, then forget it.
