TIGERFISH

The Marconi Mark 24 (Tigerfish) torpedo has an acoustic seeker in the nose. The torpedo is wire-guided and both the submarine and torpedo are fitted with wire dispensers. Data is downloaded from the submarine weapon control station to the torpedo's onboard computer. The torpedo is armed with a 134 kg PBXN 105 warhead from BAe Royal Ordnance Division. As the torpedo reaches the closest distance to the target, a magnetic proximity fuse and an impact fuse detonates the warhead. The speed of the torpedo is 25 knots in passive mode and 35 to 50 knots in active seeker mode. The range of Tigerfish is within 14 to 40 kilometres.
