KAZAN, May 10. /TASS/. The Amur Shipyard in Russia’s Far East and the Admiralty Wharves Shipyard in St. Petersburg in northwest Russia may accomplish an order for six Project 636.3 diesel-electric submarines, Head of the Navy’s Ship-Building Department Captain 1st Rank Vladimir Tryapichnikov said on Tuesday.

The submarines are designed for Russia’s Pacific Fleet, he added.

"Two shipyards are ready to build submarines of this type. The final decision has not been made yet. Probably, the order will be divided into several parts and the shipyards will accomplish each of the parts," Tryapichnikov said.

According to the official, this issue is currently under consideration.

"The decision will be made as soon as a discussion is held about whether the shipyards have the potential to fulfill the order and when they will be able to construct the submarines," he added.

As of today, the Russian Black Sea Fleet operates four Project 636.3 submarines. The Russian Navy received the lead submarine Novorossiysk in August 2014 and the second Project 636.3 submarine Rostov-on-Don on December 30, 2014.

In late 2015, the submarine Rostov-on-Don launched Kalibr cruise missiles from the Mediterranean Sea to destroy facilities of the Islamic State terrorist organization (outlawed in Russia) in Syria.

The third Project 636.3 submarine Stary Oskol joined the Russian Navy in July 2015.

The fourth submarine Krasnodar was delivered to the Navy on November 5, 2015.

All these submarines were built at the Admiralty Wharves Shipyard.

The fifth and the sixth submarines are planned to be delivered to Russia’s Black Sea Fleet this year.
