The IJN copied , one of the six, producing the ''I-21''-class minelayer submarine. The IJN could not find an optimal design of fleet submarine, so they and Kawasaki Heavy Industries sent many technical officers to the United Kingdom and Germany and got drawings of advanced submarines. The British L class became the Kaidai I, the K class became the Kaidai II and ''U-142'' become Junsen I. Junsen I Mod (''I-5'' class) This is a type which added a floatplane to the Junsen I.

Kure Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy.

Construction was supervised by the French engineer Louis-Émile Bertin. The first warship constructed at Kure, '' Miyako'', was launched in 1897. The "Kure Shipyards" were officially renamed the "Kure Naval Arsenal" in 1903. Kure developed into one of the largest shipbuilding facilities in the Empire of Japan, capable of working with the largest vessels. The Arsenal included a major steel works (built with British assistance), and also facilities for producing naval artillery and projectiles.

Floatplane
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call floatplanes "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, has greatly reduced the number of flying boats being built. However, many modern civilian aircraft have floatplane variants, most offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found their niche as one type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rabaul
Rabaul () is a township in the East New Britain province of Papua New Guinea, on the island of New Britain. It lies about to the east of the island of New Guinea. Rabaul was the provincial capital and most important settlement in the province until it was destroyed in 1994 by falling ash from a volcanic eruption in its harbor. During the eruption, ash was sent thousands of metres into the air, and the subsequent rain of ash caused 80% of the buildings in Rabaul to collapse. After the eruption the capital was moved to Kokopo, about away. Rabaul is continually threatened by volcanic activity, because it is on the edge of the Rabaul caldera, a flooded caldera of a large pyroclastic shield volcano. Rabaul was planned and built around the harbour area known as Simpsonhafen (Simpson Harbour) during the German New Guinea administration, which controlled the region from 1884 and formally through 1919. Rabaul was selected as the capital of the German New Guinea administration in 1905, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intended as large, fast vessels with the endurance and speed to operate with the Naval fleet, battle fleet, they gained notoriety and the nickname of "Kalamity class" for being involved in many accidents. Of the 18 built, none were lost through enemy action, but six sank, with significant loss of life, in accidents. Only one ever engaged an enemy vessel, ''K-7'' hitting a U-boat amidships, though the torpedo failed to explode with what has been described as typical "K" luck; ''K-7'' escaped retaliation by steaming away at speed. The class found favour with Commodore Roger Keyes, then Inspector Captain of Submarines, and with admirals Sir John Jellicoe, Commander-in-Chief British Grand Fleet, and Sir David Beatty, Commander-in-Chief Battlecruiser Squadrons.

British L-class Submarine

The scale of change allowed the L class to become a separate class. The armament was increased when the British 21 inch torpedo, 21-inch torpedoes came into service. The Group 3 boats had two QF 4 inch naval gun Mk IV, XII, XXII, QF 4-inch guns fore and aft of the lengthened conning tower. Also, 76 tons of fuel oil was carried in external wing tanks for the first time in British submarines. Several of the Group 1 boats were configured as minelayers including ''L11'' and ''L12''. In the Group 2 boats, ''L14'', ''L17'' and ''L24'' to ''L27'' were built as minelayers carrying 16 Naval mine, mines but without the two beam torpedo tubes. The introduction of the L class came too late to contribute significantly in World War I. was accidentally depth-charged by three American destroyers in early 1918. torpedoed the German submarine . torpe ...
