Russian submarines are going to be outfitted with new unique piezoceramic coating antennas capable of intercepting and distorting signals emitted by enemy sonars.
The new invention, developed by OceanPribor Concern and the Krylov Research Center under the auspices of the Foundation for Advanced Research Projects, is essentially a polymer membrane designed to cover the entire hull of a submarine. These new antennas are expected to be installed both on the next generation submarines and on the submersibles that are already employed by the Russian Navy.
A source in the Defense Ministry privy to the development of the new antenna told Russian newspaper Izvestia that the work is proceeding as planned, and that testing is expected to begin soon.
“We’re talking about a polymer membrane based on lead, titanium and zirconium oxides that can both absorb and transmit a signal. Essentially, this piezorubber coating transforms the submarine’s entire hull into a hydroacoustic antenna,” the source explained.
