The Delta IV submarines are strategic nuclear missile submarines designed to carry out strikes on military and industrial installations and naval bases. The smaller submarines are carried in special recesses under the keel of the Host Submarine beneath … She is the fourth submarine in the Project 667BDRM class (referred to as Delfin-class in Russian, Delta-IV is the NATO classification). During a modernization refit in 2004, Tula was upgraded with the capability to carry the R-29RMU Sineva liquid-fueled submarine-launched ballistic missile.

The Delta IV submarines are strategic nuclear missile submarines designed to carry out strikes on military and industrial installations and naval bases. This missile is referred by the START nuclear arms reduction treaty as the RSM-54. The submarines were originally fitted with R-29RM (Western designation SS-N-18 Skif) missiles.

It has the subtlety of a T-34 tank, in that it has simple assembly but gets the job done in an efficient manner.

The Delta IV submarines employs the D- 9RM launch system and carries 16 R-29RM liquid-fueled missiles which carry four multiple independently targetable reentry vehicles.Unlike previous modifications, the Delta IV submarine is able to fire missiles in any direction from a constant course in a circular sector. "The Russian Navy operates seven Delta IV Class strategic missile submarines."
