running torpedo with a magnetic influence detonator.The weapon's run to enable range (minimum
range) is 2000 yards.The Shkval is not a subtle weapon. Its use alerts all in the area to your
presence.When using this weapon, the hope is it will reach its target before the target can
respond. It is known that the Russians have this weapon, it is not known if it is actually carried by
the Akulas.
STRATEGIC WEAPONS
MINES: SEAWOLF AND 668(I)
MK 67 SLMM: The submarine-launched mobile mine is a modified Mk 37 torpedo whose warhead
was replaced by a Mk 13 mine warhead.The torpedo’s propulsion system is used to maneuver the
mine to the coordinates programmed into its guidance system.The SLMM has a 235 kg warhead,
a maximum speed of 26 kts and a maximum range of 11.5 n.m.
MINES: AKULA
Mobile Mine: The Akula’s mobile mine is a modified version of the 53-65K torpedo. Launched via a
53 cm torpedo tube it can travel up to 10 n.m. after leaving the ship.The mobile mine is effective
in depths from 4 – 150 meters and has a 480 kg warhead.
COUNTERMEASURES
Countermeasures are defensive weapons used to prevent an enemy’s torpedo from destroying your
sub.The two types of countermeasures available in Sub Command are active decoys and passive
decoys:
The passive decoy torpedo countermeasure is used against passive homing torpedoes.The passive
decoy emits sound (noise) across a broad spectrum of frequencies in an attempt to deceive the
torpedo into homing in on the decoy.
The active decoy torpedo countermeasure is used against active homing torpedoes.The active
decoy is a bubble generator that creates an area of bubbles in an attempt to provide a false echo
to the torpedo.
Decoys can be placed both deep and shallow when trying to ensure a decoy will be present to
deceive an inbound torpedo, and in order to have a decoy on both sides of the acoustic layer
because the depth of an inbound torpedo is usually not known. Many torpedoes employ both
passive and active homing; therefore, both passive and active countermeasure should be
employed.
BASIC STEPS FOR LAUNCHING COUNTERMEASURES
1. Decide which type of countermeasure is desirable for the situation.
2. Select a tube containing the desired countermeasure. Internal tubes can be reloaded with a
different CM if the supply of the desirable type has not been exhausted. (Check the weapon
inventory to determine how many of each countermeasure you have remaining.)
3. Determine the depth for the CM (Deep or Shallow). In the Seawolf you can set a specific depth
for each CM launched from the Countermeasure Launch Panel.
4. Launch the Countermeasure.
