Marconi Avionics developed the Attitude/Heading Reference System for both the UK Sting Ray and Spearfish heavyweight Torpedoes. The Spearfish torpedo is a dual-purpose wire-guided weapon and provides both anti-submarine warfare (ASW) and anti-surface ship warfare (ASuW) capability, replacing the Tigerfish torpedo which was withdrawn in 2004. The production contract for the Spearfish Torpedo was placed with Marconi Underwater Systems Ltd (now BAE Systems) in 1983, following a development programme lasting for several years. Spearfish entered full production in 1988, with deliveries completed in 2003.
