So, as one of my many musings, I had a thought about why the Imperial-class was as vaunted as it was by the Imperial Navy. obviously her weapons-loadout, size, and physical dimensions are sufficient enough to deal with most of the enemies that the Galactic Empire, pre-4 ABY would deal with.
but despite her size, cost, and crew-requirements, she is still seen as the de-facto Gold Standard, to which all other Warships are compared.
To sum it up, i believe that having 2 Imperial-1 class Star Destroyers is the rough equivalent of having at least 3 smaller vessels, an Acclamator-1, Venator (1), and Victory (1 or 2.), in most respects.
Armaments: an Imperial-1 has about as much fire-power as a Victory and an Acclamator. 135 weapon emplacements of various types, compared to the 50 emplacements on the Victory-2 (used because the Missile Launchers have limited utility in terms of how long they can be used or to what purposes. you can either use them up quickly in massive salvos, or use them only a few launchers at a time, which seems rather inefficient for such a large and otherwise powerful platform) and the more defensively oriented 36 emplacements on a Acclamator, and/or the 62 emplacements on a Venator. again i dont include the torpedo launchers because of their reload issues, although i would be willing to include the Acclamator's torpedoes because she carries a hundred per launcher.
