Kuma (ship)

was a light cruiser in the Imperial Japanese Navy. The lead vessel of the five ship class, she was named after the Kuma River in Kumamoto prefecture, Japan.

Background

After the construction of the s, the demerits of the small cruiser concept became apparent. At the end of 1917, plans for an additional six ''Tenryū''-class vessels, plus three new-design 7,200 ton-class scout cruisers were shelved, in place of an intermediate 5,500 ton-class vessel which could be used as both a long-range, high speed reconnaissance ship, and also as a command vessel for destroyer or submarine flotillas. ''Kuma'' was laid down at Sasebo Naval Arsenal on 29 August 1918, launched on 14 July 1919 and commissioned on 31 August 1920.

Design

The ''Kuma''-class vessels were essentially enlarged versions of the ''Tenryū''-class cruisers, with greater speed, range, and weaponry.Gardner, ''Conway's All the World's Fighting Ships 1906–1921''; page 238 With improvements in geared-turbine engine technology, the ''Kuma''-class vessels were capable of the high speed of , and a range of at .

The number of 14 cm/50 3rd Year Type naval guns was increased from four on the ''Tenryū'' class to seven on ''Kuma'': two forward, two on each side of the superstructure and three aft, which meant that only six guns could be brought to bear on a broadside. The torpedo launchers were also increased to four double launchers: however, the ''Kuma'' class remained highly deficient in anti-aircraft protection, with only two 8 cm/40 3rd Year Type naval guns and two 6.5 mm machine guns.Stille, '' Imperial Japanese Navy Light Cruisers 1941-45 '', pages 14-18;
''Kuma'' could be distinguished from her sister ships by the addition of funnel caps from 1929.Jentsura, p. 107.

Service career

Early career

Immediately after commissioning, ''Kuma'' was assigned to cover the landings of Japanese troops during the Japanese intervention in Siberia against the Bolshevik Red Army. She was subsequently based at Port Arthur, and patrolled the northern China coast between the Kwantung Leased Territory and Tsingtao.

''Kuma'' was refit in late 1934 with a tripod mast, two rotatable quadruple torpedo launchers, and an aircraft catapult for launching a reconnaissance floatplane, typically a Kawanishi E7K1 "Alf". As the Second Sino-Japanese War began to escalate, ''Kuma'' patrolled the China coast, and covered the landings of Japanese forces in central China. She was captained by Captain Tadashige Daigo from November 1935 to December 1936. In December 1937, ''Kuma'' served as flagship for a squadron of minelaying submarines through based out of Tsingtao until fall of 1938.Boyd, ''The Japanese Submarine Force''; page 54

Invasion of the Philippines

On 10 April 1941, ''Kuma'' was assigned to Vice Admiral Ibo Takahashi's CruDiv 16 in the Japanese 3rd Fleet. At the time of the attack on Pearl Harbor on 8 December 1941, ''Kuma'' was participating in the invasion of the northern Philippines, having departed from its base in Mako, Pescadores Islands with the , and destroyers and . From 10–11 December, ''Kuma'' covered landings at Aparri and Vigan; off Vigan, ''Kuma'' was attacked unsuccessfully by five USAAF Boeing B-17 Flying Fortress bombers of the 14th Squadron. On 22 December, ''Kuma'' covered further landings at Lingayen Gulf, Philippines.

On 3 January 1942, ''Kuma'' was reassigned to Vice Admiral Rokuzō Sugiyama's Third Southern Expeditionary Fleet. She was assigned to patrols around the Philippine islands from 10 January to 27 February 1942.

In March, ''Kuma'' was assigned to cover the invasion of the southern Philippines, shelling Cebu harbor on 1 March, sinking two coastal transports, and covering the landings at Zamboanga, Mindanao on 3 March. Special Naval Landing Forces (SNLF) from ''Kuma'' rescued about 80 Japanese nationals who had been interned. ''Kuma'' is also credited with sinking twelve transport vessels in the Sulu Sea off of Cebu the same night.

On 9 April 1942, off Cebu, ''Kuma'' and the torpedo boat ''Kiji'' were attacked by U.S. torpedo boats ''PT-34'' and '' PT-41''. ''Kuma'' was hit in the bow by one of eight Mark 8 torpedoes fired, but it was a dud. ''PT-34'' was destroyed by Mitsubishi F1M "Petes" launched from the seaplane tender '' Sanuki Maru''.Goodspeed, ''US Navy''; page 413

On 10 April, ''Kuma'' covered landings on Cebu by the Kawaguchi Detachment's 35th Infantry Brigade HQ and the 124th Infantry Regiment, and on 16 April landings on Panay by the Kawamura Detachment's 9th Infantry Brigade HQ and the 41st Infantry Regiment. On 6 May, ''Kuma'' covered the final assault on the American bastion on Corregidor Island in Manila Bay. Afterwards, ''Kuma'' remained on patrol at Manila until 12 August 1942.

Dutch East Indies and New Guinea campaigns

After a refit at Kure Naval Arsenal in September, ''Kuma'' returned to Manila on 20 September 1942 and was reassigned to Vice Admiral Shirō Takasu's Second Southern Expeditionary Fleet (Dutch East Indies Force). She was sent to Hong Kong to embark troops of the 38th Infantry Division, which she disembarked at Rabaul, New Britain on 10 October. ''Kuma'' then proceeded to Makassar, Celebes where she began patrols under the command of Captain Ichiro Yokoyama, with occasional embarkation of reinforcements for Rabaul, Kaimana, New Guinea and Kabui, New Guinea until 13 April 1943.

From late April through the end of May 1943, ''Kuma'' was refitted at the Seletar Naval Base Singapore, and afterwards resumed patrols around the Dutch East Indies to 23 June.

On 23 June 1943, while at Makassar with CruDiv 16's , , and , ''Kuma'' was attacked by seventeen Consolidated Aircraft B-24 Liberator bombers of the 319th Squadron/90th Bomb Group (H) of the 5th Air Force. All four light cruisers were straddled by near-misses, but suffered only slight damage.

On 24 June 1943, CruDiv 16's flag was transferred from ''Kinu'' to ''Kuma''. Both cruisers then departed Makassar for patrols around the Dutch East Indies until 23 October. From 1 November, ''Kuma'' was refit in Singapore. Her No. 5 140-mm gun was removed as were her aircraft catapult and derrick. Two triple mount Type 96 25-mm AA guns were fitted. This brought the total number of ''Kuma''s 25-mm AA guns to ten barrels (2x3, 2x2). Refit was completed by 12 November, and patrols/transport runs around the Dutch East Indies resumed, extending occasionally to Port Blair, Andaman Islands, Penang, Mergui, Burma through 9 January 1944.

On 11 January 1944, after departing from Penang with the destroyer on anti-submarine warfare exercises, ''Kuma'' was sighted by Royal Navy submarine based out of Trincomalee, Ceylon. Approximately northwest of Penang, ''Tally-Ho'' fired a seven-torpedo salvo from . ''Kuma''s lookouts spotted the torpedoes' wakes, and although the rudder was sent hard over, ''Kuma'' was hit starboard aft by two torpedoes, setting the ship on fire. ''Kuma'' sank by the stern in the vicinity of detonating her own depth charges. ''Uranami'' took on survivors, including Captain Sugino, but 138 crewmen perished with the ship.O’Connell, ''Submarine Operational Effectiveness in the 20th Century ''; page 94

''Kuma'' was removed from the navy list on 10 March 1944.

The wreck

''Kuma''s wreck was discovered in March 2004 by a group of divers including Australian explorer Kevin Denlay operating off the research vessel MV ''Empress'', based out of Singapore. The wreck was found to be on its starboard side in of water, covered in fishing nets and snagged fishing lines. The bridge structure was fairly intact, although half-buried in bottom silt, and her funnels had fallen off. The port side waist 5.5-inch gun was basically intact, as were the two on the fore-deck, although the top of the waist mount enclosure had partially disintegrated. The circular rotating base of the forward port torpedo rack was intact, but there were no torpedo tubes mounted on it. However, the aft port rotating torpedo tube mount had completely fallen off the ship. The glass in many of the portholes, especially amidships, has been melted and fused due to the intensity of the fire that raged while the vessel was sinking. The ship's stern was missing completely aft of where the torpedoes hit; all that remained was a jagged edge, although the outboard port propeller and shaft were still visible protruding from the wreck.

In 2014 it was reported that illegal salvagers recovered scrap metal from several shipwrecks, including ''Kuma''. Subsequent reports state that the wreck is almost completely gone now.
