Russian submarine Novomoskovsk
1990 Delta IV-class submarine
K-407 Novomoskovsk is a Project 667BDRM Delfin-class ballistic missile submarine (NATO reporting name Delta IV) of the Russian Navy's Northern Fleet.
Background
Construction of the nuclear submarine K-407 Novomoskovsk began at the Northern Machinebuilding Enterprise (Sevmash) in Severodvinsk on 2 February 1987, and it became part of the Soviet Navy on 27 November 1990. She was the last of seven 667BDRM Delfin submarines and the last SSBN submarine built in the USSR. This class of submarines was developed at the Rubin Design Bureau in 1975 and is considered one of the most successful Soviet submarine missile carrier designs.
Specification
The submarine has a submerged displacement of 18,200 tons and a surface displacement of 11,700 tons. It is 167 m (547 ft 11 in) long and 11.7 m (38 ft 5 in) wide. It is powered by two nuclear reactors with a total power of 180 MW (240,000 hp). The submarine's immersion depth is 400 m (1,300 ft); its surface speed is 14 knots (26 km/h; 16 mph), and its underwater speed is 24 knots (44 km/h; 28 mph). It carries a crew of 135. Armaments include a D-9RM missile system (16 RSM-54 ballistic missiles) and four 533 mm (21.0 in) torpedo tubes.
The RSM-54 missile (3M37, R-29RM, or SS-N-23 according to the NATO classification) is a liquid-propellant, three-stage missile with separable heads (it carries four or ten warheads depending on the modification).
This brief starts where responsible research should: with the source description of “Russian submarine Novomoskovsk” as 1990 Delta IV-class submarine. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1990 Delta IV-class submarine. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q4324578. Authority coordinates are 69.500, 34.200. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1987, 1990 and 1975.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
