Work on the U.S.S. Kentucky was stopped when that ship was about 75% complete.
It was _officially_ scrapped in 1950.  Another Iowa-class ship, the U.S.S.
Illinois, was scrapped at 20% complete. 

Interestingly, the four G.E. steam turbines intended for the Kentucky ended up
in the first two units of the Sacramento-class Fast Combat Support ships
(Sacramento and Camden, launched in '64 and '67.)  While the Iowas used 600
p.s.i. Babcock & Wilcox boilers to supply the four turbines, producing a total
of 212,000 horsepower, the Sacramentos used Combustion Engineering boilers with
two turbines each, for 100,000 horsepower total. The Iowas, with twice the
power, 4 screws, not much more tonnage, and a longer hull, could manage 33
knots, while the Sacramentos could do 27.5 knots. (This just illustrates how
non-linear the effects of increased power are - of course, there are other
variables!) 

The Sacramento class is noteworthy - they are the world's largest at-sea
replenishment vessels, at 53000 tons full load. (The closest rival is the
Soviet Berezina, at 40000 tons.) They have three helicopter hangars and operate
two CH-46 Sea Knights for VERTREP (vertical replenishment) operations. 

A defensive armament of one NATA Sea Sparrow launcher and two Phalanx mountings
is shipped. Inexplicably, the ships are equipped for sonar, although it has
never been mounted.
