The maximum safe diving depth of the I-400-class submarine was only 82% of its overall length, which presented problems if the submarine dived at too steep an angle in an emergency. [19] Because of their large aircraft hangars and conning tower, all I-400 -class boats had significant visual and radar signatures on the surface, and could be ...
Until the commissioning of the United States Navy ballistic missile submarine USS Benjamin Franklin (SSBN-640) in 1965, the I-400-class were the largest submarines ever commissioned. [3] U.S. Navy personnel inspect I-400′s aircraft hangar after World War II. U.S. Navy personnel examine I-400′s deck gun at Yokosuka, Japan, on 14 October 1945.
An I-400 class submarine, with its long plane hangar and forward catapult. The I-400-class submarines were the largest submarines of World War II and remained the largest ever built until the construction of nuclear ballistic missile submarines in the 1960s. It displaced 6,500 tons (5,900 tonnes) and was over 400 ft (120 m) long, three times ...
The Japanese applied the concept of the "submarine aircraft carrier" extensively, starting with the J3 type of 1937–38. Altogether 41 submarines were built with the capability to carry seaplanes. Most IJN submarine aircraft carriers could carry only one aircraft, but I-14 had hangar space for two, and the giant I-400 class, three.
I-400-class submarines had a rather noisy special trim system that allowed them to loiter submerged and stationary while awaiting the return of their aircraft; [2] [8] demagnetization cables meant to protect against magnetic mines by nullifying the submarine′s magnetic field; [9] an air search radar, two air/surface-search radar sets, and a ...
Type J1M scouting submarine (one built, I-5) The first IJN submarine to carry a floatplane, completed 1 July 1932. No catapult was fitted, the I-5 aircraft was assembled on deck and lowered into the water for takeoff. Had two hangars. Type J2 scouting submarine (one built, I-6) Carried one floatplane Type J3 scouting submarine (two built, I-7 ...
The I-400-class submarines had four 1,680 kW (2,250 hp) diesel engines and carried enough fuel to circumnavigate the world one-and-a-half times. Measuring 122 m (400 ft) long overall, they displaced 5,900 t (6,504 short tons), more than double their typical American contemporaries [3] and much larger than the most common Japanese submarine of the era, the Type B1, which was 109 meters (356 ft ...
