The Hatsuharus
were completed in 1933-35, primarily
in naval yards. They had the distinction of being the first
Japanese destroyers
to enter service armed with the Long
Lance torpedo.
The London Naval Treaty
of 1930 allowed each navy to build a maximum of 16% of its destroyers
with a displacement of up to 1850 tons. The remainder could not exceed
1500 tons. By the time the Hatsuharus
were under design, Japan had reached its quota for the heavier
destroyers, and the new class attempted to fit as much of the
capability of the 1850 ton destroyers as possible onto a 1500 ton
displacement. Considerable ingenuity went into weight savings, but the
design attempted too much, and the final weight was greater than hoped
for. The ships were also quite top heavy.
After the Tomozuru
capsized in a typhoon,
the Hatsuharus were thoroughly
redesigned to reduce top weight. The superstructure was cut down, a
single 5" gun and one bank of torpedoes was removed, and displacement
increased to 2099 tons. (Japan had by this point renounced the naval
treaty system.) Thus stabilized, the ships became capable units.
However, six additional units planned were redesigned as the Shiratsuyu class to incorporate the
lessons learned from the first six units.
