Kilo's with propulsors

[Kapitan]

562 feet in length (not far off the modern day HMS ark royal)
82.2 feet wide (almost twice as wide as a ohio SSBN)
48,000 tonnes (almost 2 and a half times the wieght of HMS Ark royal

So yup she is massive by any scale, infact there was planns to convert the submarine into a gas carrying transport submarine once they had decomissioned them.

In comparison though the reason why the typhoon only carrys 20 missiles instead of 24 is because of the sheer size.

The SS-N-20 missile is alot larger than a trident, and almost 30 tonnes heavier, to compair the SS-N-20 is 93 tonnes compaired to the trident's 59 tonnes. (http://www.fas.org/nuke/guide/usa/slbm/d-5.htm)

Sadly all typhoons will be laid up pending disposal by 2010 the last is the TK208 Dmitri Donskoy which is being used as a trials submarine, however TK20 Severstal and TK13 Simbrisk remain active all are based at Zapadnya Litsa.

When construction was approved The typhoons were to number 12 but only 7 were built (7th being broken up before completion).

A sobering note is that these submarines have enough nuclear warheads to destroy europe (main citys and towns), due to START and SALT treatys the number of warhead carried have been reduced to 200 per boat.

Up untill 1998 all the typhoon submarines names and penant numbers remained a state seacret.

In essence the OK-650B has been surpassed that reactor is now far obsolete and is only kept on the submarines because they only have a few more years to go before they retire, the eldest submarine being over 30 years old and the youngest nearing 20.
