Hi Jesse,
Floating drydock lists plans for the "LSD-45 - Comstock",
G-LSD45 - USS LSD45 AS BUILT

However, I do not see the hull lines listed anywhere. So you ar kind of on your own for the hull. If you have images of any of the ships in drydock, or under construction, Or if you create a waterline scale model, the hull won't be to difficult to mock up.
