SURTASS LFA
SURTASS LFA
  • The Navy Fleet Commanders in Chief (CINCs) have determined that SURTASS LFA sonar is a crucial element of the Navy's anti-submarine warfare (ASW) force and is an asset required for our national security. 
       
  • SURTASS LFA sonar will be employed in compliance with the National Environmental Policy Act, Marine Mammal Protection Act, Endangered Species Act, Coastal Zone Management Act, and Presidential Executive Order 12114 (Environmental Effects Abroad of Major Federal Actions).
       
  • LFA sonar must transmit high intensity sound in order to detect submarines at long range.
       
  • LFA sonar uses sound levels similar to the mid-frequency tactical sonars, which have been used worldwide for over 50 years.
       
  • It is highly unlikely that sound levels below 180 dB will cause injury to marine mammals or other marine life. Click here to read a paper explaining this in more detail.
       
  • Undersea earthquakes and even lightning strikes generate powerful low frequency sounds. Many whale species also produce loud, low frequency sounds. These natural phenomena were part of the environment in which marine mammals evolved. This helps to explain why the whales exposed to LFA sonar signals during the Low Frequency Sound Scientific Research Program exhibited less response than the scientific team anticipated. 
       
  • To provide an objective analysis of potential effects from LFA sonar on marine life, a team of independent marine biologists was engaged to conduct research and provide technical evaluations. The Navy provided no direction to their scientific protocols. Their scientific findings were published with no Navy review in advance. 
       
  • The Navy has spent over $16 million conducting scientific research and developing an Environmental Impact Statement, including the development of a state-of-the-art marine mammal mitigation system.
       
  • Monitoring and mitigation measures will reduce to a negligible level the risk of harm to any marine mammal from LFA sonar.
