Imperial-II class Star Destroyer

The Imperial-II class Star Destroyer, shortened to the Imperial-II also known as the ISD-II (Imperial Star Destroyer-II) is a Star Destroyer model that was derived from the Imperial-I class Star Destroyer. In some cases the Imperial-II can be referred to as the Imperial Star Destroyer and Star Destroyer which can be easily confused with the Imperial-I.

Weapons, Design, and Complement
There are differences between the Imperial-I and the Imperial-II, such as the tractor beam globes being replaced with a communications tower. The ship is built to have more firepower than the Imperial-I a stronger hull, and stronger defensive shields. Rather than the Dual Laser Cannons and the heavy ion cannons that flanked the first ship, the Imperial II has batteries of eight-barreled turbolasers or ions in Octuple barbette turbolasers. Another new feature includes two parallel "claws" for grappling smaller starships placed in the ventral secondary docking bay. They carry the exact same complement of Stormtroopers and TIE starfighters.

Weakness
Despite these weapons, the Imperial-II has numerous problems, such as breaking down easily. Though there are many more problems that have yet to be exploited by the CIS and Rebels, the ship continues to be formidable against other enemies.

Identification
The 2 Star Destroyers can easily be confused by the sensor array on top of the Imperial-class Star Destroyers towers. The Imperial-I has support beams running diagonally across it. These are later substituted for vertical ones during a minor refit, which make the array look similar to the one on Imperial-II vessels. To identify them, the Imperial-I has Dual Laser Cannons flanking the tower's side while the Imperial-II has octuple barbette turbolasers flanking tower.
