April 1967, project Phyllis Ann changed to become Compass Dart. On 1 April 1968, Compass Dart became Combat Cougar. Because of security concerns the operation's name changed two more times first to Combat Cross and then to Commando Forge. Project Drillpress also used modified C-47s, listening into VC/PAVN traffic and collected intelligence from it. This data gave insights into the plans and strategy of both the VC and the PAVN. Information from all three projects contributed in a major way to the intelligence picture of the battlefield in Vietnam. In fact about 95 percent of the Arc Light strikes conducted in South Vietnam were based, at least partially, on the data from these three programs. On 6 October 1967, Drillpress changed to Sentinel Sara. The US would go to great lengths to prevent this equipment from falling into enemy hands, when an EC-47 from the 362d TEWS crashed on 22 April 1970, members of an explosive ordnance unit policed the area destroying anything they found and six F-100 tactical air sorties hit the area to be sure. Detachments of these squadrons operated from different locations, including bases in Thailand. Each of the main squadrons and their detachments moved at least once due to operational and/or security reasons. Personnel operating the RDF and signal intelligence equipment in the back of the modified EC-47s were part of the 6994th Security Squadron. On 1 June 1969 the unit transferred to become 360th TEWS Det 1. Inactivation As the Vietnamization program began, Vietnamese crews began flying with EC-47 crews from the 360th TEWS and 6994th SS, on 8 May 1971, to get training on operating the aircraft and its systems. The wing was inactivated in-place on 31 August 1971.
