At 1,600 meters (5,200 ft) long, Imperial-class Star Destroyers are crewed by 9,235 Officers, 27,850 enlisted personnel, and 275 Gunners. The Imperial I is armed with 60 turbolasers, 60 ion cannons, and 10 tractor beam projectors for space combat.

Star Wars: Uprising states that the Empire had 25,000 Imperial Star Destroyer with 45,000 Stormtroopers aboard the vessel. Now if we do simple math, that would come out to 1.1 billion. The Galactic Empire never revealed the true number of Stormtroopers. As far as we know, there were billions.

Is A Star Destroyer bigger than a Venator?
Although Venators were still active at the time of the Galactic Civil War, they had mostly been replaced by the Imperial-class Star Destroyer, a larger warship modeled on its Republic predecessor.
The Executor serves as Darth Vader's flagship during the events of The Empire Strikes Back, leading the Death Squadron against the Rebel Alliance on Hoth and in pursuit of the Millennium Falcon.
Description. One of the largest and most powerful Imperial vessels ever created, the Executor was 19,000 meters long, eclipsing its escorting Imperial-class Star Destroyers, and boasted more than 5,000 turbolasers and ion cannons.
These engines add to the fear factor of the ship, glowing blood-red, rather than the more normal blue. The Executor-class's bridge, which contains large deflection/communication spheres, is at its rear; another common feature throughout the Star Destroyer range.
A Star Destroyer will cost $636 billion to build the parts on Earth, plus $44.4 trillion to get it all off Earth and to Mars. At that launch cost, it's definitely worth investing in asteroid mining and refining technologies first.
Depending on the size of the scouts and platoons, it may reach as high as 3,669 units, composed of 3,200 troopers and 468 officers. Battalion—613 units: 4 companies (612 units: 512 troopers and 100 officers) led by a major.
A capital ship built on a nearly unimaginable scale, the Supremacy is a vast flying wing more than 60 kilometers wide. In addition to being a warship with enormous firepower, it serves Supreme Leader Snoke as throne room and the First Order as mobile capital.
In these cases, Star Dreadnoughts were noted as being the largest Super Star Destroyers. In turn, the lower-case term star dreadnought could be used to describe Super Star Destroyers in general.
Sensor globes used on top of Star Destroyers and Super Star Destroyers contained hyperwave transceiver coils and long-range scanners, part of the com-scan system of the ship.
"The Eclipse." The Eclipse was an Executor-class Star Dreadnought in service of the Galactic Empire. It also served as the flagship of Emperor Sheev Palpatine during the Age of the Empire.
Yes, he lost some of his connection to the force when he lost his limbs, but that doesn't change the fact that he is the most powerful. Pulling down that star destroyer would've been child's play for him.
According to one source, a single Class-I Imperial Star Destroyer would cost around $636 billion apiece. And that's just for the basic parts. Getting all that stuff into space would likely push the budget into the many trillions using conventional means like rockets.
The term "Super Star Destroyer" described some of the largest warships ever designed and fielded, and covered various warship classes that served primarily as command ships. All the known models were at least several kilometers long in order to support their increasingly heavy power generators and armaments.
Although the Xyston-class Star Destroyer successfully raided and obliterated the planet Kijimi, it would not see action until the climactic Battle of Exegol in 35 ABY, where the 1,080 Sith Star Destroyers faced overwhelming odds.
