The superconducting quantum interference device (SQUID) program at the Defence Research Establishment Pacific began in the mid-1970’s and continued until 1995. At that time the program was shifted to the Defence Research Establishment Atlantic where it continued until July 2000. The goal of this program was to develop and demonstrate a next-generation airborne magnetic gradient sensor for use in anti-submarine warfare. Almost all of the sensor development and a large portion of developing the data acquisition software was done under contract, but most of the research on characterizing noise sources in moving gradiometers, and designing/building the electronics and tow-body were done in-house. In June 1998, a flight test of the entire system was conducted using a Canadian Coast Guard helicopter. Although the results looked promising, the program was eventually terminated due to lack of personnel and resources. This report gives a brief history of the airborne SQUID program, the results achieved, and the unresolved issues at the time of termination. It also presents the status of other mobile SQUID sensor programs in the US, Germany, the UK, and Australia as of August 2001 for comparison.
