U.S. admits germ war tests in Britain & North America

WASHINGTON (Reuters) - The United States has acknowledged it carried out a sweeping Cold War-era test programme of chemical and germ warfare agents in Britain and North America.

An unknown number of civilians were exposed at the time to "simulants", or what were then thought to be harmless agents meant to stand in for deadlier ones, the Defense Department said. Some of those were later discovered to be dangerous.

"We do know that some civilians were exposed in tests that occurred in Hawaii, possibly in Alaska and possibly in Florida," said William Winkenwerder, assistant secretary of defense for health affairs.

Also exposed or possibly exposed were civilians in or around Vieques, Puerto Rico, and an unknown number of U.S. service personnel, said Michael Kilpatrick of the Pentagon's Deployment Health Support Directorate.

As many as 5,500 members of the U.S. armed forces were involved, including 5,000 who took part in previously disclosed ship-board experiments in the Pacific in the 1960s, the Pentagon said.

So far, more than 50 veterans have filed claims related to symptoms they associate with exposure to the tests, the Department of Veterans Affairs said.

The tests of such nerve agents as Sarin, Soman, Tabun and VX were carried out from 1962 to 1973 both on land and at sea "out of concern for our ability to protect and defend against these potential threats," a Pentagon statement said on Wednesday. The tests were co-ordinated by an outfit called the Deseret Test Center at Fort Douglas, Utah.

The reports amounted to an acknowledgement of much wider Cold War testing of toxic arms involving U.S. forces than earlier admitted by the Pentagon.

"During this period there were serious and legitimate concerns about the Soviet Union's chemical and biological warfare programme," Winkenwerder added at a Pentagon news briefing.

But the tests also had applications to the offensive chemical and biological weapons stocks then maintained by the United States, he said. President Richard Nixon ordered an end to U.S. offensive chemical and biological weapons programmes in 1970.

Britain and Canada joined the United States in a series of tests on their military proving grounds from July 1967 to September 1968, a document released by the Pentagon said.

These joint exercises, known as Rapid Tan 1, 2 and 3, were designed to investigate "the extent and duration of hazard" following a Tabun, Soman or other nerve agent attack, a fact sheet said. These agents, along with VX, were sprayed in both open grassland and wooded terrain at the Chemical Defence Establishment in Porton Down, Wiltshire, the document said.

Similar tests took place at the Suffield Defence Research Establishment in Ralston, Canada, the Pentagon said.

"The weapons systems germane to this test were explosive munitions (Soman-filled), aircraft spray, rain-type munitions (using both Tabun and Soman), and massive bombs (Tabun- and Soman-filled), the fact sheet said.
