Size matters!

[CINDERS]

Here is a pic of the rear end of a Typhon submarine the size of the two submariners in the picture gives you the sense of scale of these massive subs.
Yes they were big which did not matter as they stayed under the polar icecap hiding from US subs ready for the command.
Which would see them break through the ice and deliver a devastating nuclear attack on their adversary.
The Typhoon had 2 separate hulls made of titanium with a 6" layer of rubber covering the whole lot they even had a small swimming pool for the crew to use!
Interesting thing on the Typhoon the missile launchers are situated down the centre line of the twin hulls in front of the sail unlike conventional subs which had them inboard along, basically the centerline of the submarine at the rear of the sail.
Type Ballistic missile submarine
Displacement
23,200 t (22,830 long tons) surfaced
48,000 t (47,240 long tons) submerged

Another cool feature of the pic is you can see the propellers and their blade design & pitch which is unusual from a censors point of view not scrubbing them out.
They are a closely guarded thing and you'll never see pics of a US propeller on their submarine such is their classified nature.
Normally they are odd numbered bladed with I.E 5-7-9 blades which may have to do with harmonics and tracking noise from them, one thing the Typhoon is a big sub.
I think there is only one left in service now.

Interesting thing on the Typhoon the missile launchers are situated down each side Port/Starboard unlike conventional subs which had them inboard along, basically the centerline of the submarine.

I thought Typhoons had two main pressure hulls with the missiles in between.

Yes, the Typhoons were massive, around 23,000 tons surfaced. MAC is correct, the missile tube pairs were on the centerline of the sub and the last one was decommissioned some years ago when the U.S. and apparently Canada offered to pay the bulk of the cost of the decommissioning.

two main pressure hulls

You're correct Mac my error (corrected thread)
I'll search around as I am sure I saw pics of a sub with the launchers along each side.

It does seem familiar, and now you've got me wondering which it was!

I knew I had seen one it is the Russian OSCAR II sub that they are calling the aircraft carrier killer.
