High pressure air compressors consisted of an opposed piston two stroke Diesel driving reciprocating multi-stage compressors, were developed by Junkers AG in Germany around 1935. It was introduced to Japan by the Imperial Japanese Navy for generating high pressure air to launch torpedos and to produce oxygen for propulsion agent of torpedos. Kobe Steel, Ltd. and Mitsui Seiki, Ltd. were appointed by the navy to be their manufacturers under license of Junkers. The contract was made and actual machineries were imported. After it was adopted officially by the Navy, some hundreds of units were manufactured and supplied to the Navy for military use. The application of the compressor was later widened to lower pressure for general purpose, and manufacturing and supplying to open customers continued nearly 20 years. The history was traced inside of Kobe Steel, Ltd. and reported.
