Of the original seven Delta IV submarines, how many are anticipated to remain in active service and available for patrol? I hear five.

No, I think it's six.

BS-64 will return in 2010. The rebuild of K-64 Delta IV began in 1999 according Project Standard 09774. This entails the elimination of rocket section and insert an additional section from KS-411 (Yankee Stretch) with a length of about 43 meters, which significantly increased the size of the unit to approx.175m.
Gained in this way the space would be used for the installation of research equipment, as well as Cabin and housing for researchers.
The entire structure has been adapted to carry a miniature underwater rescue vehicles Paltus project 1083.1. The ship will be based at Olenya Bay replacing KS-411 as mothership for the small research submarines.

I thought the sixth submarine had been converted for special-ops and the seventh de-commissioned and was being held for parts. Pavel, do you have a list of hull numbers and names for the six? Thanks as always.

Frank: It's all here - http://russianforces.org/navy/

K-18 Kareliya
K-51 Verkhoturie
K-84 Ekaterinburg
K-114 Tula
K-117 Bryansk
K-64 Vladimir (converting to BS-64 special missions)

Is the submarine I’m missing the K-407 Novomoskovsk?

My confusion was with the K-64 which was declared for scrap by the Admiralty in February 2001 long after it was taken into conversion for “special purposes” in 1999. I wasn’t sure if it was indeed the K-64 being converted or yet another of the Project 667BDRM (Delta IVs).

I think you forget K-407 Novomoskovsk. She is in Sevmash for overhaul (until 2010-2011.
