It will then issue a command to turn towards the target. Two acoustic transducers will react upon sound and the torpedo will detect that the signal comes from one of the side. Acoustic torpedoes are usually designed for medium-range use. How do Modern Warships Defend Themselves Against Torpedoes? 14 Acoustic Homing TorpedoesĪn acoustic torpedo is a torpedo that aims itself by listening for characteristic sounds of its target or by searching for it using sonar (acoustic homing). The high-capacity guidewire system (in some fiber optic wire), specifically designed to match the torpedoes’ maneuver and speed envelope, provides two-way data exchange between the torpedo and launch submarine, maximizing the submarine’s organic sensor and combat control capabilities. In a typical engagement, the torpedo will run out wire-guided to the target’s general vicinity and then conduct a covert passive and after active search. Mark 23 Straight Runner Torpedo Wire homing Torpedoes All nations have their own tactics for maneuvers. They can only be countered by maneuvers or hardkill defense. In terms of acoustic signatures, they produce a high radiated noise level and are comparatively easy to detect. They are launched at Short to Medium ranges run in pre-designed patterns and don’t have the re-attack capability. Modern Torpedoes Straight Runners (Some navies still use them) To understand the torpedo countermeasures system, we should start with the features of modern torpedoes. The attacker could layer the attack with smaller weapons and a standard heavyweight torpedo, as well. ![]() ![]() It approaches its target with zig zag movement in terminal phase.Ī single submarine could also launch a flurry of the mini-torpedoes at a single surface or sub-surface target, which would help overwhelm its defenses. Like some missiles, they approach the ship with random movements like zig-zag in their terminal phase, making them harder to track or target. Most of them have re-attack capabilities. Some of them do not explode until detecting the hull of the real ship. Torpedoes are becoming more dangerous day by day with new capabilities. The fact that very few countries have the decent capability to develop an effective torpedo defense and there is no single effective system deployed (both Hard Kill & Soft Kill) that can claim to be highly effective against a broad range of Torpedoes (Wake Homing, Active/Passive Homing, Straight Runners, Multiple torpedoes). Artist rendering Submarine firing heavyweight torpedoes Torpedo detection is difficult due to large launching distances and unfavorable sound propagation conditions, particularly in littoral waters. They are quiet and radiate little noise therefore, ASW forces must use active sonar for torpedo detection. HWT typically launched from submarines at a large distance of 10,000-15000 m. In this article, we will focus on submarine-launched torpedoes and their countermeasures systems. ![]() ![]() Torpedo boats are also carrying anti-ship torpedoes against warships. Heavyweight submarine-launched torpedoes (HWT) are the main torpedo threat for warships. ![]()
