>From deep-ecology-L: Subj: USA Sound Warfare Systems Date: 00-08-08 03:24:40 EDT To: [EMAIL PROTECTED] Hi, There are two US systems under development: LFAS (Low Freq. Active Sonar) and, LWAD (Littoral Weapons Acoustic Development). The first is an aggressive probe that relates to the news articles appended below. The second is less well known and I have struggled to source information as it's still under wraps. LFAS is properly known as LFAS - SURTASS, but is often erroneously referred to as LFA. A look at the photographs of this system is telling, but LWAD is LWAD and I have yet to see images of this system, if anyone does have pics please contact me. LWAD relates to the use of intense sound to destroy enemy troops as they incur across beach (littoral) regions. If these weapons are perfected it remains to be seen if they are placed in the same category as blinding weapons - primarily lasers that are designed to blind enemy troops permanently but effect no other damage. This follows the classic military strategy that a dead soldier doesn't impede the enemy but an incapacitated one drains the enemy as they have to look after their own. Either way, the LFAS and LWAD systems are clearly destructive to marine ecosystems and so should be opposed. Remember the Chinese knew about explosive a 1000 years before Westerners but declared them forbidden for warfare as they were too nasty and violent and destructive. The Chinese restricted explosives to fireworks. However, the brilliant minds of Western military institutions thought; 'Whoo-Hoo!!' Jon _________________________________________________ OCEANS An intense underwater noise or explosive pressure led to the strandings of five beaked whales in March, federal marine biologists said. The strandings occurred while the U.S. Navy was conducting tests of a powerful sonar system. Biologists reported on autopsies performed on four Cuvier's beaked whales, and one Blainville's dense beaked whale, which all showed evidence of severe trauma to their ears and other areas. "The injuries were not consistent with a nearby explosion (there were no bone fractures), but could have been caused by a distant explosion, or an intense acoustic event." The findings are the first to link a distant noise or explosion with whale strandings. In March, the Navy was testing the Littoral Warfare Advanced Development (LWAD) system. That system uses active sonar to send out loud sounds that bounce off nearly silent submarines and other underwater targets. It uses middle frequencies, which are believed to be less harmful to marine species than the low frequency sonar used in some newer systems, like the Surveillance Towed Array Sonar System (SURTASS) Low Frequency Active (LFA) Sonar. The Navy seeks to deploy SURTASS in 80 percent of the world's oceans. The $350 million system emits sounds at decibel levels known to cause trauma to nearby listeners, both human and animal. Little is known about deep sea whales. Ten environmental groups began arguments before the Federal District Court in Honolulu challenging the Navy's plan to deploy LFA sonar systems. The case is led by the Hawai'i County Green Party, and by Julie Jacobson, a Green Party member of the Hawai'i County Council. The key allegation in the challenge is that the Navy is preparing to deploy the LFA sonar system before completing an environmental impact statement (EIS). http://www.ilhawaii.net/~light/lfaindex.html (ENS -06 15/6) * * * A study published in today's "Nature" finds that male humpback whales changed their mating songs under the influence of the Navy's experimental Low Frequency Active (LFA) Sonar. A team of U.S. scientists carried on a Navy research vessel broadcast 10, 42-second-long LFA signals at 16 humpback whales off the coast of Hawaii in 1998. The sonar transmissions were weaker than those used in normal LFA sonar operations. Miller said: "The sonar was turned down quite a bit from the actual level they use when they're looking for submarines." During the transmissions, five of the whales stopped singing altogether. The songs of the remaining whales lasted about 30% longer than normal. "We didn't observe any sorts of extreme reactions."
