Specifications of the U.S.S. Neosho
When it was built in 1939, the U.S.S. Neosho (AO-23) was the largest tanker in the world. With the probability of America participating
in World War II looming ever closer, the Navy wanted this to be a fast ship, able to keep up with aircraft carriers and cruisers when refueling them at
high speed on the open ocean, so they cancelled the original plan of having only a single propeller and instead redesigned it with two propellers.
It was the second Navy ship named U.S.S. Neosho (see The Four U.S.S. Neoshos).
Here are the specifications of the U.S.S. Neosho:

By comparison, here are the specifications for a modern oil tanker, the Exxon Valdez. The Exxon Valdez is
perhaps the most famous (infamous?) tanker in the world, having ran aground in Alaska in 1989 and causing a massive
oil spill. The Exxon Valdez, which was repaired and now has a different name, is about twice as long, twice as wide, and
twice as deep as was the Neosho and has about 10 times the capacity:
Length: 987 feet
Beam: 166 feet
Draft: 64 feet
Displacement: 211,469 tons
Maximum Speed: 16 knots
