Devastator Class Star Destroyer

The Devastator class star destroyer was a heavy frigate that was constructed by Kuat Drive Yards, and served in the Imperial navy, being used as  a frontline vessel, able to take down fighter squadrons and larger ships with ease. The ship was popular among Imperial officers for its' ability to take on ships almost twice its' size, and survive, due to its' heavy armour plating and shields.

Dimensions
The Devastator class star destroyer was a front line battleship, not a true star destroyer, but thanks to its' complement of heavy weapons and reinforced hull, it could fight alongside star destroyers with very little differences. They were classified as 'heavy frigates' to mark their difference in combat abilities to the Maximus class frigate.

They were just under a kilometer in length, and had a broad, triangular shape. The bridge, like most Imperial ships, was situated just ahead of the engine compartments, and presented one of the Devastators greatest weaknesses. Despite this, the frigate had superb shields, almost as strong as an Imperial III class star destroyer, which allowed it to go up against larger ships, for a time, anyways.

Offensive and defensive systems
A Devastator class star destroyer was designed to go toe to toe with enemy ships. They were equipped with 4 quad turbolaser batteries, 12 heavy turbolaser cannons, 24 laser cannons, 20 Ion cannons, and 80 concussion missile tubes. The weaponry of a Devastator was designed to cause maximum damage to the shields and hull of enemy ships. It was often designated a capital ship killer, as a single volley of concussion missiles were enough to rip through the hulls of most large ships it faced off against.

Devastators were also chosen for orbital bombardments, due to the fact that only a few missiles could destroy a city, or tear open most bunkers. In addition, the volley of concussion missiles could be used to great affect against light corvette-class vessels, or starfighters in tight formation. After the concussion missiles had shredded the starfighters, the destroyer would launch its' squadrons of TIEs. Due to this strategy, the Devastator-class was one of the only ships known to launch a fighter screen after its' initial assault.

A major weakness of the Devastator was that most of its' weapons, except its quad laser batteries, were more forwards on the hull. This meant that the destroyers were extremely vulnerable from a rear attack, and they relied on their shields and fighter complements to defend them.

Defense wise, the Devastator-class had very strong shields, compared to other ships of its' class. Due to these shields, Devastators could hold out against numerous smaller ships, and sometimes several larger ships. They also relied on the shields to protect their rears from enemy assaults. The hull of the Devastator class was considerably weaker. Though it could hold out for a time against ships of the same or lesser classes. A determined assault by large numbers of ships or a capital ship would likely punch through the hull.
