Ultra in the Battle of Britain: the Real Key to Sucess.

摘要

The basic question is whether or not Ultra intelligence contributed more to the British victory in the Battle of Britain than other sources of intelligence. Possible future uses of the historical lessons learned are examined. Data was gathered through an extensive literary review, a trip to England, and personal interviews with British authorities on the subject. The role of Ultra in the Battle of Britain was significant to the outcome of the battle; however, insufficient evidence exists to determine if it was more important than other sources of intelligence. Radar and lower-grade radio intercepts also made a significant contribution; thus, until more Ultra files are declassified and released to the Public Record Office, final determination of findings must be held in abeyance. However, numerous lessons learned are applicable to the United States' current domestic and international situation. Actions to be taken include: continuation of study when appropriate Ultra files are released; development of SIGINT means should be given highest priority; reduce military use of radios and 'secure' devices; improve collation of strategic and tactical intelligence--provide to division level; improve COMSEC; acquaint military and national leaders with lessons of the Battle of Britain; immediately improve CONUS air defense; most importantly, review and update contingency plans for defense of CONUS.
