Euronaval, 24 October 2012 – The official qualification trials of the sonars for the FREMM frigate programme took place over a six-week period in June and July 2012 on the FREMM frigate Aquitaine in the Bay of Biscay. The successful trials are the culmination of nine months of testing with the UMS 4110 CL bow-mounted sonar and CAPTAS 4249 towed-array sonar, which have now achieved Level 1 at-sea qualification.
