Developed by GEC Marconi, originally for the Batch 2 Leander Class frigates. A very low frequency, passive, 500m long towed array, it underwent trials, initially on HMS Matapan, then on HMS Lowestoft (a Type 12 Rothesay Class frigate) around 1977/78. First conversions to Leander Class began in 1980.
