Russian submarines to receive new sonar absorbent composites


Russia’s Krylov State Research Center (KSRC) has developed innovative new technologies, which will reduce the ability of sonar to detect Russian submarines, according to Valeriy Shaposhnikov, chief of KSRC’s endurance and shipping hull construction unit.

“We have developed the appropriate technologies and constructions made of composites,” Shaposhnikov said. These new multilayer composites the company is using have a structure and consistency that absorb sonar signals, thereby preventing the detection of a submarine via hydroacoustics. “Such effect is provided by the extremely complex inner structure of the composite developed by KSRC,” he added.

The innovative developments are currently undergoing stand trials, which include strength tests. According to Shaposhnikov, the control surfaces of a submarine can be made from the new composites.
