Missile launch today

I can see there are one Delta 3 and five Delta 4 still in active service, servicelife is coming to an end with this very succesful class of SSBNs. The last will probably be decomissioned by the late 2020s, ie sometime 2027-2028.

IIRC Orenburg (BS-126) was converted to as a mini-sub tender, but Ryazan (K-44) is still in service?

Makes sense, those are delivery dates for Borei SSBNs

What happened to K-84 Yekaterinburg? withdrawn from service?

Well that sucks. Probably damage from the fire it had back in 2011 was not fully recovered and the navy has decided that another dry dock repair and refit is not feasible.

Deltas are old and Boreis are coming online, no need to drag out the inevitable

Delta IV is a well-regarded sub, home, and abroad. And given that the Layner missile is quite modern and formidable, I think Deltas will easily serve an additional decade-plus. I don't think there'll be a rush to decommission them.

Decade plus is about time until all Boreis come into service so it all fits

I hope they re-build it to some UUV carrier or something else.

Or an SSGN with a massive capacity to deliver a f*ck ton of hurt.

Neither, it's getting scrapped

One that could be getting converted to spy sub is K-44 Ryazan

This is consistent with maintaining a strategic submarine force of 12 SSBN

This year the 5th Borey, the Knyaz Oleg, has to enter the service.

Then the figure of 12 SSBN will have been reached in the ranks of the Russian Navy: 5 Borey's, 6 Delta IV and 1 Detla III


Since the 6th Borey will enter service in 2022, then a Delta must be decommissioned, probably a few months in advance, as the crew will transfer from the decommissioned submarine to the submarine that begins Navy testing.

Ryazan will be scrapped as soon as the new SSBNs arrive to the Pacific Fleet
May be used in the short term simply to train crews for new assignments.

For special missions, specific submarines of the projects 09851 and 09852 are also already being built (the Belgorod that is already in tests).

Belgorod is a spy sub but Khabarovsk is not, it's a dedicated Poseidon carrier

Interesting piccie of K-18 Karelia. An uncommon POV...

Quite a rare view as well - great pic!

Not sure where the Delta class sub thread is. Anyway Sub Brief just released his lectures on the Delta 2 sub and Delta 3 sub. The original lecture he did on the Delta was quality so I assume these would be pretty good too. Worth a watch if you are a sub geek

Great video. Here's the Delta-III link

Delta IV sub that used a torpedo to make a hole in the ice and then surfaced.
