Highlights

GAO completed a followup review to a 1978 report on navigation planning. The report concluded that, because the Department of Defense (DOD) planned to replace the Tactical Air Navigation System (TACAN) with the NAVSTAR/Global Positioning System (GPS), expenditures to modernize and buy new TACAN equipment were questionable. The report also pointed out that interim fielding of new TACAN equipment could result in unnecessary expenditures and duplication and that, to maximize the GPS cost effectiveness, DOD should avoid buying new equipment that GPS could replace. Despite this, the Navy and the Air Force plan to spend approximately $49 million in the next 4 years on additional replacement TACAN equipment.
