'Who Shoots First Wins': Russian Submarines
Receive Advanced 'Duel' Torpedoes

Russia’s nuclear-powered Borei- and
Yasen-class submarines will be capable of hitting a target from any depth,
before being detected by the enemy. The submarines will be armed with the UGST
modernized thermal torpedo known as Fizik-2.
Despite the fact that the technical specifications
of the new weapons are kept secret, it is reported that the torpedo
outperforms the Mk 48 Mod 7 Spiral torpedo of the United States Navy,
in terms of noise level, velocity and hitting range. The Fizik-2 can
travel 10 km longer than its American analogue and hit any type
of target, including submarines and aircraft carriers.
The torpedo was developed by Research & Design
Institute "Morteplotekhnika," a part of Tactical Missiles Corp.
One of its engineers Alexei Grigoryev told the
Russian newspaper Izvestia that the new torpedo has already entered
service with the Russian Naval Force.
"In the long run the torpedo will replace
all electric-propelled torpedoes with the Russian Navy," Grigoryev
said.
The Fizik-2 is a so-called duel torpedo. It has a length
of 7.2 meters. It has a flattened nose cone and control surfaces. However
the main feature of the UGST torpedo is an axial internal-combustion
engine which has its pistons moving parallel to the shaft.
The Fizik-2 uses a water jet instead of a propeller.
This allows for reducing noise and increasing its maximum speed,
up to 60 knots (over 110 kph).
According to Vadim Kozyulin, a professor at the
Russian Academy of Military Sciences, the US Navy no longer uses
electric-propelled torpedoes.
"Currently, the main torpedo of the US Navy is
the Mk 48 heated torpedo. It is powered by an internal-combustion engine.
This allows for higher speeds and a larger traveling range. Until
recently, Russia did not have such a torpedo suitable for a 533-mm
launcher," Kozyulin told Izvestia.
According to the expert, modern torpedo combat is
like a "knife fight in a telephone box."
"Who shoots first wins," Kozyulin
said, adding that the Fizik-2 torpedo gives the Russian Navy a serious
advantage over its potential rivals.
Unlike its predecessors, the Fizik-2 can be launched
from a depth of up to 500 meters, which is nearly the critical
operational depth for modern nuclear submarines. The torpedo has pullout
control surfaces, which pop up right after the launch. Such a design
allows for reducing noise and providing a greater maneuverability.
The Fizik-2 acquires a target with the use of a
dual-channel target seeker. It is based on an active-passive hydroacoustic
system capable of detecting the target’s wake at a distance
of 1.2-2.5 km. The torpedo has a hitting range of up to 50 km
and can carry a warhead of up to 300 kilograms.

UNIVERSAL DEEP-WATER HOMING TORPEDO UGST

First torpedo UGST demonstrated in 2003 in the seaside
cabin IMDS-2003 in St. Petersburg. Moreover, when a torpedo like the first time
publicly present a wide range of experts, because of some problems with special
services UGST on the second day to hide from spectators, wrapped it in a carpet
and rewinding the tape. 533-mm torpedo UGST equipped with a warhead weighing
300 kilograms and is designed to destroy warships and submarines at a distance
of 50 kilometers. The torpedo is equipped with a combination of acoustic homing
system also allowed remote control (from a board of the submarine).

Power plant torpedo UGST based on the axial piston motor
ADF Development Research Institute "Morteplotehnika" 1995. Engine
feature - a rotating combustion chamber in which fuel is supplied to a
high-pressure plunger pump under pressure up to 35 MPa. It uses established
liquid monopropellant. The starting powder charge that is placed in the
combustion chamber, allows to rapidly increase the power that along with high
performance engine is important in the initial portion of movement of the
torpedo. In the engine as in the torpedo generally applied modern technologies
improve vibroacoustic characteristics, thereby reducing the external noise to
the required level of the torpedo and provided optimal conditions homing
operation.

For similar torpedoes intended UGST in SRI
"Morteplotehnika" created thermal propulsion SCC-53 system for
universal torpedo caliber of 533 mm.
SCC-53 CHARACTERISTICS:
Caliber RTD, mm: 533
TPN Length, mm: 4100 ... 5500
TPN Weight kg to 1400
Engine Type TPS: turbine
of open cycle
Maximum TPN engine power kV, up to: 800
Type propulsor TPN: the jet
fuel composition TPN: liquid fuel type Otto-fuel;
Otto-fuel + oxidizer NAR
Quiet water jets UGST directly without gearbox connected
to the engine. Hydrodynamic circuit UGST distinguish biplanar rudders.
Retractable for bypass torpedo after it emerges from the torpedo tubes. This
scheme reduces the noise of the torpedo. Structure tail part provides an
interface to the carrier placement na¬vesnyh telecontrol systems and data
entry.

High torpedo "Physicist-1" (product 2534) and
the advanced version "Physicist-2" or "Physicist-2000"
(name of export UGST-M) have been created for the Russian Navy using UGST
developments of the torpedo. At the end of 2014 after the successful completion
of state tests was adopted by a new deep-sea thermal homing torpedo
"Physicist". This torpedo will be rearmed with all submarine of
project 955 "Borey", 885 "Ash", as well as their
modifications. Other submarines of the Russian Navy will be rearmed with an
increase in the release of data torpedoes. Series production is planned to
establish a new torpedoes at the "Dagdizel". For these purposes in
2015 will be allocated 1 billion rubles, according to the Ministry of Industry,
Trade and Investment Dagestan.
