How numerous is the Imperial Fleet (Star Wars) and what sort of ships does it consist of?
gpt
For a full summery i would suggest checking out the Imperal Navy page on the Wookiepedia holonet site, but the short version is alot. starwars(dot)wikia(dot)com(slash)wiki(slash)Imperial_Navy

The Imperial Navy was one of the most formidable militaries ever assembled, consisting of millions of warships, fighters and transports, manned by trillions of fleet crew. The mainstays of its fleets - the Star Destroyer and Super Star Destroyer capital ships and the TIE fighter series of starfighters - became some of the most visible symbols of Imperial rule to the galaxy's civilian populace.

There were close to 10 diffrent modles of the Imperal Star destroyers serving functions from missile ship to scout to tackling pirates. Where all previous units were generally bound to specific system or set of systems, the Imperial Navy designated a fleet as a "sector resource", allowing it to operate on a sector-wide scale. A fleet was the smallest unit transferred between sectors. With such a large number of units, there were thousands of potential types of fleet alignments. Common fleet deployment types included superiority fleets, assault fleets, and bombard fleets. Other examples of alignments that a fleet might have taken included a deepdock fleet, support fleet, or ordinance fleet.

Superiority fleets maintained space superiority in sectors with "four or fewer world confirmed hostile to the New Order, and no more than 16 additional worlds with confirmed significant hostile elements", a superiority fleet was deployed. With six Imperial-class Star Destroyers and almost 400 other starships, a superiority fleet was presumed to be a sufficient force for relatively calm sectors.

Assault fleets transported huge numbers of Imperial Army and Navy troops to coordinate ground operations, while maintaining space superiority around the targeted systems. With two transport forces and two force escorts, an assault fleet engaged in massive planetary and system-wide ground campaigns.

Bombard fleets contained an average of 416 ships, allocated between two system bombards and two force escorts. Bombard fleets were assigned to sectors where the Empire had determined the probability of repressing the Rebellion in the sector to be less than even. System bombards were used when the Empire would rather completely destroy a world than see it fall into Rebel hands.

17 dreadnought types
11 battle cruiser types
21 types of destroyers
22 crusier types
11 carriers
13 frigates
14 corvettes
60+ fighter and scout ships
all of these filled specfic rolls in their fleets or units.
