Gigantic spaceship, thin and long. It reminds me of a submarine

gigantic spaceship, thin and long. It reminds me of a submarine. At the top we have huge 2-gun turrets. The main command tower is located towards the rear of the ship.. It is formed by a block, the command section and on the sides we have the spherical antennas. The propulsion system is double, i.e., a huge propulsion system on each side of the ship at the back. The ship is white with red details. Below the ship we have the entrance and exit deck for the smaller ships..
