2008, three Plowshares activists entered the GCSB Waihopai base near Blenheim, New Zealand and punctured an inflated radome used in the ECHELON signal interception program, causing $1.2 million in damages. In March 2010 the three men stood trial by jury at the District Court in Wellington and were acquitted. The New Zealand Attorney-General then lodged a civil claim, on behalf of the GCSB, for $1.2 million. This claim was dropped in February 2014. On November 2, 2009, a Plowshares action took place in the U.S. at Naval Base Kitsap-Bangor, where Trident nuclear weapons are stored or deployed on Trident submarines. These weapons constitute the largest stockpile of nuclear weapons in the US. On July 28, 2012, three Plowshares activists, Sr Megan Rice, SHCJ, Greg Boertje-Obed, and Michael Walli, who compose the Transform Now Plowshares movement, breached security at the U.S. Department of Energy's Y-12 National Security Complex in Oak Ridge, Tennessee, causing the government to temporarily shut down the weapons facility. Once inside a "secure" area, the activists hung protest banners on a uranium storage site, poured human blood and spray-painted the walls with anti-war slogans. Following a controversial trial, the three activists were convicted in early May 2013 on the charges of damaging property in violation of 18 US Code 1363, damaging federal property in excess of $1000 in violation of 18 US Code 1361, and intending to injure, interfere with, or obstruct the national defense of the United States and willful damage of national security premises in violation of 18 US Code 2155. Megan Rice was sentenced to 35 months, or just under three years. The other two protesters, Greg Boertje-Obed and Michael Walli, both were sentenced to 62 months, or a little more than five years. The National Nuclear Security Administration has acknowledged the seriousness of the 2012 Plowshares action, which involved the protesters walking into a high-security zone of the plant, calling the security breach "unprecedented." Independent security contractor, WSI, has since had a weeklong "security stand-down," a halt to weapons production, and mandatory refresher training for all security staff. Non-proliferation policy experts are concerned about the relative ease with which these unarmed, unsophisticated protesters could cut through a fence and walk into the center of the facility. This is further evidence that nuclear security—the securing of highly enriched uranium and plutonium—should be a top priority to prevent terrorist groups from acquiring nuclear bomb-making material.
