Based on the results of this month's Operational Evaluation trial of their new Low- Frequency Active Passive Sonar (LFAPS) aboard one of the Royal Netherlands Navy's
M class frigates, Lieutenant-General Rob Verkerk, Commander of the Royal Netherlands Navy, tweeted "Testing with Low Frequency Active Passive Sonar (LFAPS) onboard HMNS Van Amstel. Quantum Leap in the field of submarine warfare!"
The OPEVAL was conducted over several days in conjunction with a WALRUS class submarine and a NH-90 helicopter, which was fitted with a low frequency, dipping sonar. The trial demonstrated the LFAPS's abilities to mono-statically and bi-statically detect and track a diesel-electric submarine, in challenging environmental conditions, in littoral waters.
Ultra Electronics Maritime Systems is pleased to have supported the Dutch Defence Materiel Organisation (DMO) through the development of LFAPS hardware; the LFAPS processing software was developed by the Netherlands Organisation for Applied Scientific Research (TNO).
