Destroyer
From Planetarion Wiki
The Destroyer, 1 of only 2 vessels in the Destroyer class, this ship was the first to be designed solely by the War Scientists. Extremely effective against 'Pirates' this relatively well-armoured craft (due to the metal/crystal bonded plating) is also the only vessel that can take on a Battleship successfully. Its manoeuvrability is hampered due to mass increase, a side effect of the use of crystal technology, but its recently upgraded weaponry makes it a favourite choice for the average warmonger.
^The above refers to 'Destroyer' and 'Pirate' as they were during earlier rounds of Planterion. Right now, the Destroyer is a ship class, and the pirate is a Zikonian BS-DE Steal ship.
