Battlecruiser
Terran's flagship the Battlecruiser is back with new weapons, popularly known in the voice of Russian accent "Battlcruiser operational". This heavily armored combat ships are virtual flying fortresses, built to keep the peace and dominate the space lanes of the Koprulu sector. Outfitted with bristling laser batteries and thick neosteel armor, these imposing vessels are among the most powerful to be found in terran space. Many commanders use battlecruisers as their command vessels during extended campaigns.
Research has led to the development of two alternative weapon upgrades that can be retrofitted into a battlecruiser hull to supplement its already formidable armament.
Plasma Torpedos:
For me it just similar to The Banshee's cluster rockets which is an anti-ground bombardment.
Yamato Cannon:
The Yamato cannon is a terrifying weapon that uses an intense magnetic field to focus a nuclear detonation into a cohesive beam of energy. The cannon requires a huge reserve of energy to fire, but its effects on the target are impressive, to say the least.
