The K-114 Tula submarine of the Delta IV/Project 667BDRM class returned to the Northern Fleet after an overhaul and sea trials.

However, it is probably too early to say it's back in service - it may have to wait till it gets its complement of missiles. Flight tests of the R-29RM Sineva missile, which will be deployed on Tula, have been completed relatively recently, in June 2004, and Tula is the third in line to get them - after K-51 Verkhoturie and K-84 Ekaterinburg. To have all these submarines equipped with missiles, the Krasnoyarsk Mashinie-Building Plant would have to manufacture about two missiles a month. Not impossible, of course, but unlikely.
