Design[edit]

The ship originated as an experimental scout cruiser that would have the combat potential of the standard 5,000 t (4,900 long tons) Japanese light cruisers on a much lighter ship. The ship was designed by Lt. Cmdr. Fujimoto Kikuo under the direction of the head of the IJN Shipbuilding Section, Constructor Captain Yuzuru Hiraga. The entire main battery was mounted on the centre line in turrets. To save weight, the armor was integrated into the hull structure. The forecastle was given significant flare to improve seakeeping. Destroyer-type machinery was used to save weight, with eight oil-fired Kanpon boilers trunked into a single large funnel.[1]

Many of Yubari's design features were used in the contemporaneous Furutaka-class heavy cruisers, and in subsequent Japanese warships.

The ship was completed 419 t (412 long tons) (13%) over the designed displacement, resulting in an extra foot of draft and a loss of 1.5 kn (2.8 km/h; 1.7 mph) in designed speed.[2]

The ship had a significant refit in early 1944 when the two single 140 mm (5.5 in) guns were removed, one 120 mm (4.7 in) gun (in the "A" position) and six twin and one triple 25 mm anti-aircraft guns were added together with a search radar and depth charges.[3]

Service history[edit]

Yubari was based out of Truk from late 1941 through 1942.[4] Yubari was the flagship of the Japanese invasion force during the invasion of Wake Island. She led both invasion attempts on 11 and 23 December 1941.[5]

Subsequently, Yubari and her destroyers participated in the capture of Rabaul. She was next assigned as the flagship of the Port Moresby Attack Force during Operation MO, returning to Truk when the operation was cancelled.[6]

Beginning in mid-1942, she took part in the Solomon Islands Campaign, including landing personnel on Guadalcanal to construct an airfield, and later participated in the Battle of Savo Island.[7][8] One of the torpedoes which sank the heavy cruiser USS Vincennes has been attributed to her.

Yubari was sunk on 27 April 1944 off Palau by the US submarine Bluegill.[9]
