The Admiralteyskiye Verfi ship-yard is to conduct the St. Petersburg fourth-generation non-nuclear submarine's trial run late this May.

Talking to RIA Novosti here today, people at the ship-yard's press center noted that mooring tests would be completed by that time. Such tests involve the ship-yard's specialists, as well as those from the Rubin naval design bureau (that had developed the submarine).

The Russian Navy will receive the St. Petersburg submarine in late 2005, that is, after all tests are completed. This submarine's keel was laid in 1997.

The new submarine's improved specifications will make it possible to effectively hit underwater and surface targets alike. She will also launch missile salvos. The submarine features new-generation radio-electronic equipment replete with a modern elements base, a permanent-magnet electric propulsion unit (that can operate in just about any mode), as well as a storage battery with an extended service life.

Noise levels have been reduced several times over. The submarine hull also features a new and effective anti-sonar coating. She boasts a comprehensive automated-control system for her weaponry and technical systems, too.

The submarine's sonar complex features a highly sensitive sound locator in the bow section. The sound locator's area exceeds that of previous-generation subs' sound locators several-fold. The navigation complex ensures navigation safety, also making it possible to launch cruise missiles, while the submarine remains underwater for a long time. All retractable systems, except the commander's periscope, do not penetrate the submarine's pressure hull.

Peter the Great had established Admiralteiskye Verfi, which is Russia's oldest ship-yard, November 5, 1704. As of today, this enterprise designs, produces and upgrades civilian ships and warships, too. It has built more than 2,600 ships over the last 300 years.
