Way too big. That’s Drydock 12 at Newport News Shipbuilding, which is some 2173 feet (~660 meters) long. 150 meters should be roughly 1/4 of that drydock, but the ship looks like it takes up closer to 2/3 of the available space, meaning it appears closer to about 400 meters in length.

150m

For the Tantive IV length? Wookiepedia says 126 meters.
