The ISD is variably used as a destroyer, cruiser, battlecruiser, carrier, troopship, and commandship.
Its typical EU use is in the battleship role.
However, in the canon movies, it serves as a destroyer in the first and second films, and a cruiser in the third.
In High Command-sanctioned Imperial fleets, such as the Deep Core Reserve Fleets, Death Squadron, and Giel's Armada, as well as the various personal vessels utilized by Lord Darth Vader, suggests indeed that the
Imperial-class Star Destroyer is purchased by the Imperial Navy as a multi-purpose destroyer designed to support and escort larger vessels.
For Lord Vader,
Imperial-class ships are seen forming blockades and screening for blockade runners, as well as deploying minor "police role" forces to small worlds. They escort a supercarrier/commandship in deploying a major assault on a relatively small base and also form pursuit and blockade duties. For Giel, a large Imperial battleship/commandship and several cruisers and carriers are escorted by many dozens of Imperial-class ships, again, as destroyers. At Byss they serve as customs vessels, screening in coming shipping, and escorting larger craft. At Mon Calamari, they act as support and escort vessels for the much larger World Devestators and
Allegiance-class ships as cruisers at best, and still, easily destroyers.
I think this fits in perfectly with the Navy/Starfleet dichotomy theorized by Marina. The
Imperial-class, originally designed and marketed as a destroyer for the Navy's large scale-type fleets also has a repitoire of other mission capabilities.
Sectorial Moff Governors purchased the
Imperial-class for their own Starfleets, making them
the ship-of-the-line for the Imperial Sector Groups. However, the needs of these local permanent occupation and anti-rebel forces did not require massive, seventeen-kilometer commandships, eight-kilometer battleships, tweleve-kilometer battlecruisers; rather, the multi-role ISD could fill the roles of fast battleship and light carrier/troopship in most situations a Sector Group would encounter, and thus centered their forces around this excellent spacecraft, filling the remainder of their orders-of-battle with cheaper small-scale support and picket craft such as the
Nebulon-B as a frigate or destroyer, the
Victory-class as a battlecruiser, the
CR90 as a Corvette, and the
Dreadnought as a cruiser and the
Lancers and
Carracks as destroyers and picket ships, and even the small
Escort Carrier as a tiny picket carrier vessel.
Quite simply, the ISD was intended and sold to the central government as a destroyer, but circumstance and convienence ended up utilizing it often other ways (particularly against the absurdly small NR ships).
I also think you have some confusion about the destroyer role, which Ender can explain in depth.
Alyeska wrote:And 1 billion Imperial ships is absurd. The biggest estimates for the NR was 30,000 ships and Thrawn had 25% of the Empire at his point. He didn't have even 1% of the fleet size you indicate.
Where do we get 30,000 ships for the Empire when Thrawn was around? And you neglect that the Emperor recalled nearly the entire Imperial Navy and much of the local Starfleets to the Deep Core, faciliating his massive blitzkrieg known as Operation SHADOWHAND a year later.
The Navy/Starfleet dichotomy fixes the scale and WEG number contradictions while relying on canon implication and WEG information to reach that conclusion.
Alyeska wrote:Oh yes, the far larger ships classes which were built in such stunning numbers I can practicaly count ALL of them on two hands. Then there is the fact that the ISD was built at 25K tops. Given its stature and its numbers the ship filled the role of cruiser.
Really? All of the High Command-sanctioned fleet commands were of the "Saxtonian" large-scale, with ISDs as destroyers. The Byss Reserve Fleet easily had a 1000+ of the larger craft.
Alyeska wrote:PS, the Empire loved big ships and tried using them against enemies when possible. Your argument fails because the Empire wasn't using ISDs because they could get away with it. They were using ISDs because those were the biggest ships they could afford to send after the enemies.
Bullshit. The mere existance of the Death Stars proves the Empire was actually quite minimalistic and undermilitarized. Their military forces were usually quite appropriate for their targets. (ie., the Death Squadron detachment at Hoth VI was quite small compared to the force the Navy could've fielded when compared with commands at Endor and Giel's command; merely a textbook Imperial Sourcebook-style assault as called for on any industrialized world, substituting one ISD for the
Executor).
You also ignore that the ISD is not really a large ship. The Trade Federation easily fielded tens of thousands of much larger fleet carriers (don't use the weak "converted freighter" cop-out; they were still military vessels and each had to be powerfully modified and refitted, not to mention having thousands upon thousands of war droids, armored vehicles, fighters, and nearly 50 TL turrets of ISD I-scale).
