Non-AIP conventional diesel-electric attack submarine Type-209 has been investigated. As it follows from HYPERLINK HYPERLINK the Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft (HDW) of Germany. Five variants of the Type 209/1100-1500 have been successfully exported to 13 countries, 61 submarines being built and commissioned between 1971 and 2008. One of the common drawbacks of this class submarines is absence of AIP system. Only one boat Type 209/1200 Poseidon class of the Greek Navy under the Neptune II upgrade program was equipped with AIP system. The 120 kW Siemens’s AIP system is located in separate 6.5 m section that was fitted into aft part of submarine Okeanos (S-118) that in 1979 was commissioned. We propose the new concept of CCD AIP system. Such system has simple and compact design. The system is intended to develop a brake power up to 300 or 600 kW. Existing non-AIP submarines can be fitted with new CCD AIP without cutting-in an additional AIP section in submarine’s hull.
