The stealth capabilities of the Project 677 Lada non-nuclear submarines are significantly superior to those of their predecessors, said Igor Vilnit, general director of the submarine's developer, the Rubin Central Design Bureau of Marine Engineering.
The first serial-produced Project 677 Lada submarine, the Kronstadt, built at the Admiralty shipyards in St. Petersburg, is being readied for delivery to the Russian Navy.
"In terms of stealth parameters, this submarine is several times superior to its predecessors. The boat maintains an extremely low noise level thanks to its specially designed equipment. Additionally, it extensively incorporates modern acoustic protection equipment, an external anti-hydrolocation coating, and carefully designed hull contours to ensure low visibility," Vilnit said in an interview.
Rubin's general director highlighted that Project 677 submarines have a "very powerful" hydroacoustic system. What's more, he spotlighted the impressive missile-torpedo arsenal, and radio-electronic weaponry found in these subs.
"I would like to emphasize the hydroacoustics of the Lada: it is not only a wider range of acoustic waves, it is a significantly longer range of target detection. It took a lot of effort to achieve this result," Vilnit specified.
A "high-speed" hydroacoustic data processing system is required to distinguish a useful signal from interference. In addition, it is necessary to classify a target, determine its speed, depth, and direction of travel.
