Marconi Avionics PLC
Marconi Avionics developed a high accuracy Digital Strapdown Attitude/Heading Reference System for the UK Spearfish heavyweight Torpedo. The system has its origins in the AHRS developed for the lightweight Sting Ray Torpedo.
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.
This unit however is a further modification of the Spearfish design which was adapted by the company research laboratory, FARL, for the MACHAN unmanned aircraft . The unit is boxed in a perspex case and does not have a Identification Plate.
