Technical Details
All modifications of the Kairyu class are constructed from 3 sections of welded steel bolted together. The sections are the fore (warhead), mid (diesel engine, ballast, fuel, controls and batteries) and finally the aft (motor and control planes).
The bow section can be installed with or without a warhead.
Following on from the bow is the central section, first in this section are the batteries for the electric motor and the air flasks. Then is the pilot area. He has numerous controls including controls for the fore and aft dive planes and rudders, valves for oil, fuel and water and the periscope raise/lower controls. Behind the pilot are the main ballast tank and fuel tank.
Abaft the fuel tank and ballast tank is the in-line six diesel engine, followed by the aft trim tanks, gearbox and reduction motors and finally the electric motor and propellers.
In the conning tower there is usually a large magnetic compass however in some early models there is a gyrocompass in the boat itself.

“Anyone can see that to write Uncle Tom’s Cabin on the knee in the kitchen, with constant calls to cooking and other details of housework to punctuate the paragraphs, was a more difficult achievement than to write it at leisure in a quiet room.”
