The Kaidai type submarine (海大型潜水艦 Kaidai-gata sensuikan) was a type of 1st class submarine operated by the Imperial Japanese Navy (IJN) before and during World War II. The type name, was shortened to Kaigun-shiki Ōgata Sensuikan (海軍式大型潜水艦 Navy Large Type Submarine).[1]
All Kaidai-class submarines originally had a two digit boat name, from I-51 onwards. On 20 May 1942, all Kaidai submarines added a '1' to their name. For example, I-52 became I-152. Ships are listed by the three digit boat name if they had one, two digit if they were not granted one or left service before 20 May 1942.
Class variants
The Kaidai type submarines were divided into seven classes and two sub-classes:
- Kaidai I (海大1型（伊五十一型） Kaidai-ichi-gata, I-51-class)
- Kaidai II (海大2型（伊五二型/伊百五十二型） Kaidai-ni-gata, I-52/I-152-class)
- Kaidai IIIa (海大3型a（伊五三型/伊百五十三型） Kaidai-san-gata-ē, I-53/I-153-class)
- Kaidai IIIb (海大3型b（伊五六型/伊百五十六型） Kaidai-san-gata-bī, I-56/I-156-class)
- Kaidai IV (海大4型（伊六一型/伊百六十二型） Kaidai-yon-gata, I-61/I-162-class)
- Kaidai V (海大5型（伊六五型/伊百六十五型） Kaidai-go-gata, I-65/I-165-class)
- Kaidai VIa (海大6型a（伊六八型/伊百六十八型） Kaidai-roku-gata-ē, I-68/I-168-class)

Kaidai I (I-51 class)
I-51 in 1924
Project number S22. The prototype for the class. The sole Kaidai I, I-51, was based on World War I-era German submarines. She was completed in 1924, refitted with new engines in 1932 and scrapped in 1941. I-51 never saw combat.[2]

Kaidai II (I-152 class)
I-152
Project number S25. There was only 1 Kaidai II, I-152 planned under the Eight-six fleet together with the I-51. She was completed in 1924, used as a training vessel until mid-1942, then struck from service. She was scrapped in 1946.

Kaidai IIIa/b (I-153 class and I-156 class)
I-158 in 1927
Project number S26 (Kaidai IIIa) and S27 (Kaidai IIIb). The nine Kaidai IIIs were based on earlier designs, but featured a strengthened hull. The "IIIb" types were 40 cm longer and had a different bow design. All nine boats were constructed between 1927 and 1930.[4]
Of the nine Kaidai IIIs, seven survived the war, as they spent much of their time as training vessels. These were scuttled or scrapped shortly after the end of World War II. I-63 was sunk in a collision with I-60 in 1939, the former losing all her crew. I-63 was refloated and scrapped in 1940. I-60 was later sunk by HMS Jupiter.[4]

Project number S29. Three Kaidai Vs were constructed; I-165, I-166, and I-67 which were all completed in 1932. The design saw the upgrade of the deck weapon from a 50 cal to a 65 cal dual-purpose gun. The submarine was also slightly wider and taller, with an increased crew complement of 75 and an increased maximum depth of 230 ft (70 m). I-165 was modified in 1945, her gun removed and two Kaiten midget submarines/manned torpedoes substituted.[7]
None of the Kaidai Vs survived World War II. I-67 was lost with all 87 crew during an exercise in 1940. I-165 was sunk on 27 June 1945, off the east coast of Saipan. I-166 was sunk by the British submarine HMS Telemachus on 17 July 1944, off the coast of Singapore.[7]

Kaidai VIa/b (I-168 class and I-174 class)
I-68/I-168 in 1934
Project number S31 (Kaidai VIa) and S34 (Kaidai VIb). They were built in 1931-34 under the Maru 1 Programme and the Maru 2 Programme. Constructed between 1934 and 1938, eight Kaidai VIs were built; I-168, I-169, I-70, I-171, I-172, I-73, I-174, and I-175. At 23 knots, this type had the fastest surface speed for any submarine at the time of construction, although the speed was bettered slightly by later Japanese submarines. I-174 and I-175 were of the Kaidai VIb sub-type. They were 30 cm longer, 25 tons heavier, and equipped with a 50 cal deck weapon instead of a 65 cal.[8]
Kaidai VIs contributed to the sinking of two American aircraft carriers during World War II. The destruction of these submarines also hold some milestones; I-70 was Japan's first major warship casualty in World War II, and the sinking of I-73 represented the first warship kill by a United States Navy submarine in the war.[8]

Project number S41. The final design in the Kaidai class, ten Kaidai VIIs were ordered in 1939 (I-176 I-185), and were completed over the course of 1942 and 1943.[9] They were built in 1939 under the Maru 4 Programme. The IJN called New Kaidai (新海大型 Shin Kaidai-gata) unofficially, and intended to replace this type with Kaidai III and Kaidai IV. Instead of possessing some aft-firing torpedo tubes as all other predecessors did, the Kaidai VII's six tubes all faced forward. They had an endurance of 75 days.[10]
Seven of the ten Kaidai VIIs were sunk within their first year of operation and all ten vessels were sunk by October 1944.[10]
