I-16 submarine

I-16 submarine. The I-16 was a Type C1 submarine of the Imperial Japanese Navy constructed during the late 1930s. It served as a long-range fleet submarine and transport during the Pacific War, most notably in operations supporting I-8 and conducting supply runs to Guadalcanal. The vessel was ultimately lost in combat with United States Navy forces near the Solomon Islands in 1944.

Design and development

The I-16 was developed as part of the Junsen or "Cruiser Submarine" program, specifically the C1-type designed for long-range offensive patrols. Its design was overseen by Captain Kiyoshi Hasegawa and built at the Kure Naval Arsenal, sharing characteristics with the earlier Type B1 submarine. Key features included a powerful diesel-electric propulsion system, a high surface speed, and a substantial operational range intended for extended missions across the Pacific Ocean. The submarine was also equipped with a Yokosuka E14Y reconnaissance seaplane, housed in a forward deck hangar, for scouting purposes. Armament consisted of eight 533 mm torpedo tubes and a single 14 cm/40 11th Year Type naval gun mounted on the foredeck.

Service history

Commissioned in March 1940, the I-16 initially conducted training exercises in home waters before the outbreak of the Pacific War. Following the attack on Pearl Harbor, it was deployed to support Japanese advances, participating in operations during the Battle of Midway as part of the submarine screening force. In late 1942, its role shifted significantly to that of a transport submarine, undertaking perilous supply runs to beleaguered Japanese garrisons, particularly during the Guadalcanal Campaign. A notable operation in December 1942 involved a coordinated mission with the I-20 to retrieve personnel from Guadalcanal. The I-16 later supported the infamous I-8 on its voyage to Europe, providing fuel and supplies during a rendezvous in the Indian Ocean. Throughout 1943 and early 1944, it continued dangerous transport missions to points like Buka Island and Rabaul under increasing pressure from Allied forces.

Specifications

As a Type C1 submarine, the I-16 had a standard surface displacement of 2,184 tons, increasing to 3,561 tons when submerged. It measured 109.3 meters in length overall, with a beam of 9.1 meters and a draft of 5.3 meters. Propulsion was provided by two Kampon diesel engines generating 12,400 horsepower for surface running and electric motors producing 2,000 horsepower while submerged. This gave it a maximum surface speed of 23.5 knots and a submerged speed of 8 knots. Its operational range was an impressive 14,000 nautical miles at 16 knots on the surface. The boat carried a complement of 95 officers and enlisted men. Its armament, aside from torpedo tubes, included a 14 cm deck gun and two twin-mounted Type 96 anti-aircraft guns added later in the war.

Fate

The operational career of the I-16 ended on 19 May 1944. While on a transport run from Rabaul to Buka Island, it was intercepted approximately 150 nautical miles south-southeast of Green Island by elements of the United States Navy. The destroyer escort USS ''England'', part of Captain Hamilton Hains's hunter-killer group, made sonar contact and commenced a series of depth charge attacks. After a sustained assault, the I-16 was sunk with all hands, including its commanding officer, Commander Yoshitaka Takezaki. The sinking was one of several achieved by England during a remarkable patrol that devastated a Japanese submarine reconnaissance line. The wreck of the I-16 remains on the seabed near the Solomon Islands.
