Just something fun to look at.
Victory I Star Destroyer:
Victory I -class Star Destroyers were 900 meters long, just over half the size of the later Imperial -class Star Destroyer.
A single Victory I -class Star Destroyer required 4,798 crew members and 402 gunners for optimal operation and could transport up to 2,040 troops, 8,100 metric tons of cargo, several ground vehicles like the AT-AT, and two squadrons of starfighters.

An aircraft carrier is about 330m long, so we will need about 3 of those and cost about 12.75b.
A squadron of starfighters can be based around the Joint Strike Fighter at roughly $325m each. A squadron is about 12 ships, so we need 24. Also, they need to fly in space so we will make each one also a space shuttle.
From what I can tell there are three main engines and four auxiliary engines on a Star Destroyer. I'm going to go with each of the big ones is an LHC and the aux's are about half that? So three main engines around 6.5b and the aux's are are 3.25b.
It seems like training costs for soliders and pilots range from a few tens of thousands to a couple million. There's roughly 7,500 on an SD fully loaded so lets go with about 750k for each one?
The navicomputer would be way better than anything we have so I went with 100 Tianhe-2's, which is the fastest supercomputer currently.
The Victory I-class also has about 50 armaments on it as well. These are all probably quite fancy and super cool and I'm going to go with something like the Zumwalt on this one. They are about 3.5b each.
(Hull) 3 aircraft carriers @ 12.75b = 38.25b
(Engines) 3 LHC @ 6.5b and 4 half LHC @ 3.25 = 32.5b
(Starfighters ) 24 Joint Strike Fighters @ 325m + 450m each = 18.6b
(Crew) 7,500 souls @ 750k each = 5.6b
(Weapons) 50 armaments at 3.5b each = 175b
(Navicomputer) 100 Tianhe-2 @ 390m each = 39b
So far we're at roughly 300b and we haven't even added a lot of the other stuff. In 2009, the US spent a little under this amount " to maintain troops, equipment, fleets, and bases overseas," as in for everything.
It definitely seems doable, though anything bigger would start bankrupting the world >.> So no Super Star Destroyers any time soon....
