Japanese Submarines.
Photographs and history of Japanese Submarines.
Japanese naval thoughts of the use
of the submarine in squadrons and as part of the battle fleets. this
purpose was not the best use, as later it was proven that there best use
was in the sinking of naval ships and merchant ships during patrols.

KD1 class.
ordered in 1919 and completed in June 1924 at the Kure naval yard. when
launched the I51 outclassed all other submarines afloat. Powered initially
with 4 diesel engines then reduced to two. The I51 had a range of over
20,000 nautical miles at 10 knots on the surface or
100 miles at 4 knots submerged. The I51 was a experimental submarine
and was removed from service in 1941 and was used as a training submarine
at Kure.

KD2 class In
1920 as part of that years naval building programme the Japanese
imperial navy ordered a second experimental submarine built along the
designs of the German "cruiser Submarines" which were built at
the end of world war one. I52 was a larger submarine compared to I51 although
her displacement was about the same. Completed in 1925 she joined the
the naval fleet and carried out many experiments which were the base of
future submarine development and building. In 1940 the I52
was used for training at the Kure Naval district. and became obsolete in
1942 and was scrapped between 1944 and 1945.

J1 class
Developed from the German Cruiser type submarine design. This
design was an excellent design and fulfilled all its role. These were
the first Japanese submarines armed with two 5.,5 inch gun. It had
the capability to be at sea for 60 days. it had a range of 24,000
nautical miles at 10 knots and 60 mile submerged at 3 knots.
During 1942 I 1 and I 2 were modified to a transport submarine role. it
had the 5.5 inch guns removed and a reduction of torpedo carrying capability.
In its place it could carry a 46 ft Daihatsu landing craft
or Amphibious tank or other forms of stores.

J1M class
Designed as a long range scouting submarine. When completed I5 had
a aircraft hanger which retracted into the deck when aircraft was not in
use. There were two hangers which carried the aircraft one
contained the main fuselage and the floats and the other held the wings.
this system was not satisfactory way to carry an aircraft as it had to
be assembled on the catapult and during this process the submarine was very
vulnerable as it took along time to assemble the aircraft. The seaplane
was remove din 1940 and the submarine was altered to become a attack submarine
and a 5.5 inch gun was fitted instead of the hanger. The submarine had similar
performance as the I class. During the war the submarine did
not inflict any damage on shipping before she was sunk by American DE east of Guam, 19.7.44

J3 class Designed
entirely in Japan it was a development from the Kaidai 3 type submarine
at the time of joining the Fleet they were the largest submarines
built in Japan. As
in the previous design of the I5 they carried a seaplane. and between
them they became the scouting force of thru submarine fleet. At
the end of 1944 they had there hangers and seaplane removed, and
replaced with Kaiten midget submarines. Between the class they
sunk 7 Allied merchant ships.

A1 class
Developed from the J3 submarine this was a specialized design. it
carried extra communication facilities. This was the first design
to have the seaplane hanger fitted to the Hull casing in front of
the conning tower. and a 5.5 inch gun fitted behind the conning
tower. They could remain at sea for 90 days. it had a range
of 16,000 miles at a cruising speed of 16 knots. During the war I
11 damaged a light cruiser and the whole class sunk 19
allied merchant ships. and seriously damaged three others.

A2 class
was built at the Kawasaki (Kobe) naval yard. it was designed as a
headquarters submarine. and had a radius of 22 nautical miles.
Although alot heavier than the I9 class it had the dimensions as
I9. during the war I12 sunk a merchant ship of 7,176 tons.
the loss of the submarine is not sure but her last signal was on the 5ht
of January 1945 and she probably was lost in the following few
days.
