DC/AC-converters
Because of this the classic drive for propulsion and auxiliary machinery is the DC-motor (Direct Current) together with necessary equipment for start and speed control.

Sound travels far in water, and underwater loudspeakers and hydrophones can cover quite a gap. Apparently, both the American (SOSUS) and the Russian navies have placed sonic communication equipment in the seabed of areas frequently travelled by their submarines and connected it by underwater communications cables to their land stations. If a submarine hides near such a device, it can stay in contact with its headquarters. An underwater telephone sometimes called Gertrude is also used
APPENDIX A SHIPBOARD COMMUNICATIONS EQUIPMENT
The first thrust, Joint Interoperable High Data Rate Communications, includes the research in submarine communications architectures to permit the submarine to participate in Navy and Joint forces networks.

DC/AC Inverter Family for Naval Applications
The inverter family was especially designed for the 209 Submarine Class. s consist of static power conversion equipment of the lates available technology. All components fulfill the requirements of
Submarine Communications
Submarine shipboard communications systems consist of RF antennas and radio room equipment, both RF transmitters/receivers and baseband suites. Submarines require a suite of
Submarine Electrical Systems
Interior communication (I.C.) systems in a submarine provide the means of maintaining contact, transmitting orders, and relaying indications of the condition of certain machinery or other parts of the
