Large AOE about the size of the Sacramento class ships.
Just 3 in the class

Do you have a name or identification for this group of ships?
I observe that the first differs from the other two (smaller helo pad, different superstructure shape and spacing of masts). Are the three ships considered to constitute a single class or a single ship plus class of two?
What information is available about displacements, capacities, power/speed, armament, electronics, etc.?

Hmm.... That's a good question
I didn't real think about names
Open to any suggestions

All the same class. I made one then decided to change the superstructure on the other two.
Each measure 10 1/2 cm X1.3 cm
Would you be able to figure out the displacement ? CHI naval department has an opening......lol interested?

Thanks for the offer, but I'm going to stick with my current job for a few more years, and then retire. My skill in marine engineering is mostly in propulsion plants rather than hull design, but I'll try on this.

Based on your information:
- Large AOE about the size of Sacramento class ships
- Each measure 10 1/2 cm x 1.3 cm

10 1/2 cm x 1.3 cm scales to 252 m by 31.2 m.

Sacramento class displaced 53 000 t (US ton) with dimensions of 242 m by 32.6 m.

Your ships are slightly longer and narrower than Sacramento class, so a similar displacement is reasonable. Assuming equal draught and block coefficient, I calculate a displacement of 52 820 t.

Narrower beam and increased waterline length should allow slightly higher speed at an equal power.(26 kt from 100 000 hp or 75 MW for Sacramento class). Downside is that cargo capacity would be slightly smaller, may be less resistant to rolling, and may be susceptible to hogging or sagging stresses, requiring heavier framing.

For names: All the Sacramento class were named after US cities. As a traditionalist, I believe that, in the US Navy, city names should be used for cruisers (or their equivalent). As the first of their type, Sacramento class had no direct predecessor. Previously, fleet oilers were named after rivers with Native American names and ammunition ships were named after volcanos or terms associated with fire.

The subsequent Supply class had a mixture of names: Supply (the descriptive word), Rainier (North American volcano), Arctic (the geographical area) and Bridge (name of naval officer in charge of supply during American Civil War). Of these, Supply is a good choice, but I can't think of similar names for the other two that wouldn't be better suited for a hospital ship. I don't like Arctic; this would better be applied to an icebreaker. Are there any volcanoes in your imagi-nation? I don't suppose you have enough of an historical back-story to produce names of notable supply officers in your navy.
