Mystery Behind The Sinking Of The Moskva

The symbolism of the sinking of a major naval ship is deeply complex and military history is replete with tales of how the loss of a single high value war ship perhaps impacted the larger war that the nation in question was engaged in, points out Commodore Venugopal Menon (retd).

The sinking of the Russian navy’s Black Sea fleet flagship, Moskva, on Thursday, April 14, is a major setback for Russian President Vladimir Putin and the ill-advised war launched by Moscow against Ukraine on February 24.

The symbolism of the sinking of a major naval ship is deeply complex and military history is replete with tales of major naval battles and how the loss of a single high value war ship altered the dimension of that particular operation and perhaps impacted the larger war that the nation in question was engaged in.

The last major warship to sink was the Argentinian cruiser Belgrano during the Falklands war which was torpedoed by HMS Conqueror.

The sinking of the Moskva, whether due to a strike by a Ukrainian anti-ship missile R360 Neptune or a raging fire and the sympathetic explosion of ammunition, still remains a topic for discussion, This will remain a mystery with the ship somewhere deep in the Black Sea.

Many tactical lessons will be discussed by experts from the sinking of the Moskva when more credible information is available.

However, a preliminary analysis can reveal a wide range of scenarios that fit the narrative to the causes for its sinking.

Based on available open source information and photographs, I would depict the following scenarios.

Scenario 1

Moskva hit by a Neptune Anti-Ship Missile

It is important to examine the technical and tactical data of the missile at the outset.

The R 360 Neptune Anti-Ship missile is sub sonic with following characteristics: Mass: 870 kg;
Weight of warhead: 150 kg;
Operational range: 190 nautical miles;
Capable of destroying vessels with 5,000 tonnes displacement;
Housed in TLC (Transport and Launch Containers);
Designed to operate 16 nautical miles from coastline as part of coastal battery;
Guidance: Inertial Navigation system;
Altitude during transit Phase to target: 10-15 M above surface;
Altitude during Terminal phase: 3-10 M above surface

Photographs available on the media are restricted to port side of the superstructure which is damaged considerably.

In addition, there is extensive damage on the port side hull near the waterline below the super structure.

Since the Neptune is a sea skimmer, the likelihood of the missile causing damage to the superstructure is very likely.

However it does not explain the damage to the hull near the waterline.

As per norms followed in warship construction, there is no ammunition stowage space below the super structure which is occupied by the Bridge, Operations room, CIC (Combat Information Center), Communication & EW (Electronic Warfare) suites, Sonar room, Fire control system of missiles/Anti Submarine weapons & living spaces.

Hence, the missile hit causing a sympathetic explosion of ammunition leading to sinking the ship is unlikely considering the layout of magazines on a warship.

It may also be noted that only small quantities of ready use ammunition is generally stowed on the upper decks forward of the superstructure as a standard operating procedure.

Any explosion of ready use ammunition can only cause local damage which can be contained by the crew, Another point to note is that the quantity of warhead in a Neptune missile is only 150 kg and even a salvo of two missiles is grossly inadequate to sink a ship of the size of the Moskva.

Scenario 2

This assumption is based on the premise that the Neptune missiles stuck the ship at the bridge and CIC which practically made the ship ‘Not under Command’.

Thereafter, a torpedo attack by a lurking submarine would have followed to seal the ship s fate to dispatch her to Davy Jones’s locker.

It is a possibility which cannot be ruled out as the extensive damage on the port side hull below the super structure near the waterline could be attributed to the torpedo attack which caused the ship to subsequently list heavily to port side prior to sinking.

An effective coordination by a long range maritime aircraft patrolling in the area providing target coordinates to the coast battery and the submarine is a distinct possibility.

This is not a figment of my imagination, but a proven naval tactic which cannot be ruled out.

Scenario 3

The Russian claim that the sinking of the ship was caused by internal fire on board due to an accidental explosion is very unlikely considering the location of damage sustained by the ship as interpreted from the photographs and videos in circulation.

Moreover, crews on a warship are well trained to fight fires caused by accidents and the major fire fighting system covers all compartments in a ship.

In addition, the main system is backed by secondary systems in an emergency.

Summary:

Following points are relevant in this analysis and merit attention.

  • The Moskva was commissioned in 1983 and thereafter given an extension of life in 2000 by an upgradation to onboard electronics and weapon systems.
    No work was undertaken on the ship’s hull which was laid in 1976 (46 years old).
    Hence, one can assume that the state of the hull may not be satisfactory to meet combat requirements.
  • Warships are constructed with a high degree of stability, watertight integrity and reserve of buoyancy.
    A missile hit cannot sink a warship which in this case had an armor protection for the hull as well.
  • Considering the terminal altitude of the Neptune missile, it can be assumed that the missile hit the superstructure which was damaged extensively as depicted in the photographs.
    However that alone is not enough to support an argument that the ship sank solely due to the missile attack.
  • The gaping hole near the water line could be attributed to an explosion below the water line.
    As stated earlier, the location does not correspond to an ammunition magazine.

    Hence the author would attribute that damage below water line to a torpedo attack which immediately followed the missile attack.
    Any hit at the waterline or below would cause extensive ingress of sea water which would affect stability resulting in listing of the ship to one side leading to her sinking.
    In the case of the Moskva, the poor water tight integrity made things worse.
    It is also likely that a Long Range Maritime Patrol Aircraft could have orchestrated a coordinated attack on the Russian navy’s high value flag ship.

  • As per available information, the ship’s damage control system was a weak area which could be the reason why the crew could not control the damage sustained due to series of explosions and keep the ship afloat after the attack.

Conclusion

The aim of this column has been to analyse the possible causes for the sinking of the biggest naval ship since World War II from different angles and available information.

Assumptions have been made to build different scenarios for a meaningful analysis.

It is very unlikely that the truth would emerge even if the Russian navy conducts a thorough investigation into the possible causes for the sinking of their flag ship.

Submarines are silent warriors at sea and their deployment, success or kills will always remain a closely guarded secret and in this case the nationality of the boat too (based on assumption).

This aspect has not been highlighted in any of the analysis on the subject in the media thus far and rightly so as the realms of underwater warfare will always remain a mystery.
