When a submarine launches a Torpedo the sensors in the weapon will seek the target and the weapon may seek over a wide area before locking on. It is important that the sensors do not home in on the launch vehicle so the anti-circling unit was developed to prevent this. The Mk 24 Tigerfish torpedo was a heavyweight acoustic homing torpedo used by the Royal Navy (RN) for several years and it is likely that this unit was developed for that programme. Marconi Avionics also developed the Attitude/Heading Reference System for both the UK Sting Ray and Spearfish heavyweight Torpedoes.
