Bureau of Ships, 19-N-9957

Design

The Yubari was designed by Lieutenant Commander Fujimoto Kikuo and Captain Hiraga / Captain Hiraga Yuzuru / Vice-Admiral Y. Hiraga / and was ordered under the 1917 Program / 8-4 Fleet Completion Program. The intent of the design was to have the same armament (six 5.5" guns and four torpedoes) available for a broadside as was found on a 5,000 ton cruiser with the same speed.

By having a flush deck the Yubari could operate its main armament better in rough seas.

Armament

Name Elevation Range Rate of Fire
5.5" Nendo Shiki Type 3
14 cm L/50 Type 3
30° 19,100 m 6 - 10 rpm

Armor

The side armor was used as a key part of the structure which extra stiffness to the hull which was used in later cruisers.

Engines

The engines were the same as the ones used in the Minekaze class destroyers.

The two boilers in the forward boiler room were mixed firing. Four boilers were installed in the center space. The uptakes went through one funnel.

Aft of the boilers were the turbines which were split between two engine rooms.
