The Russian Navy's Project 677 Lada-class submarine (Russian: Лада) is a class designed by the Russian Rubin Design Bureau. The class is also referred to as the Petersburg (or Sankt Peterburg or Peterburg) class, after the lead ship. A program to develop a "fourth generation" diesel-electric submarine, it aimed to produce a highly improved version of the Project 636 Kilo class with much quieter, new combat systems, and possibly air-independent propulsion.

History

The lead ship of the class, named Sankt Peterburg, was launched in October 2004 and began sea trials in November 2005. The submarine was transferred to the Russian Navy in April 2010.[1] Another two vessels are under construction at the Admiralty Shipyard with plans to launch four to six submarines by 2015. The Russian Navy had set out a requirement for a total of eight Lada-class submarines.[2]

However, in November 2011 the Russian Navy decided that this class of submarines would not be accepted into service, as the lead boat had fallen far short of requirements during tests.[3] The lead boat was retained as a test vessel to experiment with various systems, the construction of the remaining boats of the class were frozen.

On 27 July 2012, the Russian Navy commander-in-chief announced the resumption of the construction of the Lada-class submarines, having undergone design changes.[4]

Characteristics

The project 677 Lada is a Russian diesel-electric submarine developed in the late 1990s.

The submarine is designed for anti-submarine and anti-surface warfare, defense of naval bases, seashore and sea lanes, as well as for conducting reconnaissance. The class marks the first usage of the Russian navy of a mono-hull design since the 1940s.

Displacement is 25% lower than that of its predecessor, the Kilo-class submarine. Top speed submerged is 21 knots (39 km/h), up from 19 for the Kilo class. The class is designed for an endurance of 45 days with a complement of 34.

The submarine is equipped with automated combat control system Litiy, (eng. Lithium).

A model, designated as the project 1650 Amur-class submarine is offered as an export model.
