The Imperial-class Star Destroyer II Hammer was manufactured in 1 BBY at Kuat Drive Yards. Its
crew has joined and trained with it for about 6 standard months, before being placed in the 37th
fleet, patrolling the Mid-Rim.
In 0 BBY, the ISD Hammer, under the command of Captain Olin Miurt, participated in its first major
operation in the Pacification of the Polia Sector, a region near Naboo. Several attacks occurred on
civilian ships in the sector, which prompted the Imperial Navy to send the 37th in the region to
defend the Imperial citizens. After 2 months of cat and mouse game, the Imperial fleet managed
to trap the pirates responsible for the attacks, destroying them. The ISDII Hammer successfully
engaged its TIE against pirate starfighters, and Captain Miurt even had the audacity to get into
ship to ship combat, destroying an old Carack Cruiser.
After the Battle of Yavin, the Imperial Fleet was reorganized, and Miurt was promoted to Admiral.
Replacing him was Frisia Warten, a young and ambitious Captain from Corellia. The Hammer was
then placed under the 12th fleet, patrolling once again the Mid-Rim, but this time near the Hutt
sector. For two years, the fleet patrolled the system, fighting periodically against Hutt criminals.
The only event of note during that time was the Hammer being dispatched to participate in a relief
effort to save Imperial colonists in the Sarriat system, where a giant meteor struck the planet Vell,
making it uninhabitable. The Hammer's stormtroopers helped to reestablish contact with the
colonists and evacuate them from the colony.
In 3 ABY, the 12th fleet was moved in the Parmic system to fight against Admiral Harkov's forces.
Warten, impatient to get noticed by the Imperial High Command, made several bold moves in the
campaign, severely crippling the Hammer and her TIE squadrons. The ship had to be repaired at
the Kuat Drive Yards, but Warten was finally promoted somewhere else in the Empire.
The Hammer was modified while being under repair to be able to accommodate two prototypes
being tested in the Empire, the TIE Defender and the Missile boat. The ship was placed in the
Emperor's Hammer Strike Fleet, under the command of the newly promoted Grand Admiral
Ronin. The Hammer fought at the Battle of Endor with the Emperor's Hammer, where it managed
to successfully repulse several attacks by Rebel starfighters, thanks to its complement of TIE
Defenders and Missile Boats.
It wasn't enough to win the battle though, and when the Death Star exploded, along with the
death of the Emperor and Lord Vader, the Hammer left the battlefield on its own. Hopefully,
Grand Admiral Ronin survived the battle, and he hailed all Imperial ships to follow him in the Outer
Rim. The Hammer rejoined with the Emperor's Hammer Strike Fleet, and is still fighting for the
Empire since that day.
