The Sims were
completed in 1939-40. Their design was initially based on the Benhams, but the signing of
the London Treaty
in 1936 raised the tonnage limit on individual destroyers to 3000 tons
and opened new design possibilities. The final design had one more 5"
gun and one less torpedo bank than the Benhams on a stronger and more
seaworthy hull. They also introduced the Mark 37 fire control computer.
However, the first units came out 120 tons over the
design weight and had serious stability problems, requiring removal of
one bank of torpedoes and the splinter protection around the bridge and the
addition of 60 tons of ballast.
They cost about
$7,000,000 apiece (1940 dollars).
