For security purposes, the "pennant numbers" of Soviet submarines were not sequential, any more than those of Soviet surface vessels were. The names are the radiotelephonic alphabet call sign of a letter of the alphabet.
Russian biggest submarine serial number#
The NATO reporting names were based on the British (and later American) habit of naming submarines with a letter of the alphabet indicating the class, followed by a serial number of that class.
Russian biggest submarine upgrade#
The Russian Navy canceled the Typhoon submarines upgrade program because modernizing one would be as expensive as building two new Borei-class submarines,i.e.

They are powered by two nuclear water reactors, four 3,200KW turbogenerators and two 50,000hp steam turbines- that’s enough to power a small city.

It is also equipped with six 533mm (21in) torpedo tubes and type 53 torpedoes The submarine carries 20 RSM-52 SLBM (Submarine-Launched intercontinental Ballistic Missiles) each with a maximum of 10 MIRV (multiple independently targetable reentry vehicle) nuclear warheads (i.e each one is strong enough to destroy a city the size of New York.

It can sail at a speed of 22.22 knots( 25.57 mph) on the surface and 27 knots ( 31 mph) under water. The Typhoon Class submarines were known for its complete stealth and soundlessness while moving under water. They are so big that the over 150 crews can stay underneath the water for up to 120 days in normal conditions.
