Guidance Wire For Torpedoes

Guidance Wire For TorpedoesThe guidance wire acts as a medium for communication of data between the torpedo and the firing platform (ship or a submarine}. The wire is also a medium for communicating data for the guidance of the torpedo towards target during its underwater run.

DRDO has developed guidance wire spools for wire-guided torpedoes. The guidance wire of 26 km length has been divided into two spools of different lengths. Each spool has a two-core copper cable, wound with a special criss-cross winding technique for free unreeling of the cable during the underwater run of the torpedo.The entire length of the cable is free from pin holes. The two spools are interconnected by an underwater connector and can withstand a pressure of40 bar.

This system has undergone sea trials and performed satisfactorily. The system can be used for all future wire guided torpedoes having copper cable as medium of communication.
