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 ...
After hearing of the deep-running torpedo problem, most submarine skippers simply set their torpedoes' running depth to zero, [54] which risked the torpedo broaching the surface. Torpedo depth is a control problem; good depth control requires more than just measuring the torpedo's depth. A depth control system that used just depth (measured by ...
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 ...
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 ...
Control surfaces are essential for a torpedo to maintain its course and depth. A homing torpedo also needs to be able to outmaneuver a target. Good hydrodynamics are needed for it to attain high speed efficiently and also to give a long range since the torpedo has limited stored energy.
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. [3]
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.
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]
