Admiralty Shipyards, a subsidiary of Russia’s United Shipbuilding Corporation (USC), has completed the second phase of sea trials of the second Project 677 Lada-class submarine Kronstadt (B-586).
As informed, the second phase of sea trials took place in the Gulf of Finland and lasted for nine days. During the tests, the submarine dived, and the ship’s systems were tested. After completing the trials, the company’s employees began preparing the submarine for the next third stage of factory sea trials.
The vessel completed the first phase of sea tests in December last year.
The keel for the second submarine Kronstadt was laid in July 2005 and the launching ceremony was held in September 2018, 13 years after the construction started.
Project 677 or Lada-class submarines are the fourth generation of the Russian Navy’s diesel-electric submarines, measuring 66.8 meters in length. They can dive to a maximum depth of 300 meters and can operate for 45 days with a crew of 35. They displace 1,765 tons while surfaced and have six torpedo tubes.
The Lada-class submarines were designed at the Robin Naval Design Bureau using the latest technologies, including radar stealth technologies. Thanks to this, the submarines are almost completely silent, the company noted.
