Mk-48 and Mk-48 ADCAP torpedoes can be guided from a submarine by wires attached to the torpedo. They can also use their own active or passive sensors to execute programmed target search, acquisition, and attack procedures. The torpedo is designed to detonate under the keel of a surface ship, breaking the keel and destroying its structural ...
However, with only a hydrostat controlling the depth fins in a negative feedback loop, the torpedo tends to oscillate around the desired depth rather than settling to the desired depth. The addition of a pendulum allows the torpedo to sense the pitch of the torpedo. The pitch information is combined with the depth information to set the torpedo ...
Figure 2: Illustration of general torpedo fire-control problem. A straight-running torpedo has a gyroscope-based control system that ensures that the torpedo will run a straight course. [26] The torpedo can run on a course different from that of the submarine by adjusting a parameter called the gyro angle, which sets the course of the torpedo ...
The Mark 32 has been the standard anti-submarine torpedo launching system aboard United States Navy surface vessels since its introduction [3] in 1960, [citation needed] and is in use aboard the warships of several other navies.
In 2012, the AN/SLQ-25D program became a part of the Surface Ship Torpedo Defense (SSTD) program, a US Navy effort to field a system that could detect and destroy incoming torpedoes. The AN/SLQ-25D was redesignated as the AN/SLQ-25X, and it was intended to be the tow point for the torpedo detection sensors. [9]
Reflecting this change of mission, the final design of Project 627 was developed with eight 533 mm torpedo tubes instead of the initial plan for one 1,550 mm and two 533 mm torpedo tubes. Project 627/627A submarines could launch torpedoes from 100 m depth. By 1963 this class was still in service but had been overtaken by later technology. [8]
The United Kingdom Surface Ship Torpedo Defence (SSTD) system entered into service with the Royal Navy in 2004. The system is produced by Ultra Electronics [ 1 ] and is known as S2170 or Sonar 2170 [ 2 ] by the Royal Navy and as Sea Sentor in the export market.
It is now typically fitted to newer Russian vessels, though often the 650 mm torpedo tube is fitted with a 533 mm converter to enable firing of SS-N-15 missiles or Type 53 torpedoes. Russian officials have stated that a 65-76A modification of this torpedo is responsible for the 12 August 2000 explosion of the Russian submarine Kursk. [1] [2]
