Cancellation of the Army's Autonomous Navigation System

August 3, 2012

What GAO Found

Almost all ANS hardware and most software development were completed prior to its cancellation, according to the Army and GDRS. The software for the most advanced capabilities was not completed, which potentially presented the greatest complexities. GDRS had demonstrated many of ANS’s capabilities to some extent, including its capability to avoid obstacles and follow a leading vehicle through varying terrain. ANS had not yet progressed to the independent testing phase, however. In cancelling ANS and MM-UGV, the Army estimated that approximately $2.5 billion in planned funding for fiscal years 2013 to 2017 could be made available for other Army efforts. According to Army officials, the government owns the work completed on ANS to date.

To compare ANS to other alternatives, the Army engaged a team (the Red Team) to perform a functional comparison of the demonstrated capabilities of ANS and six other military and commercial systems. The Red Team, comprised of robotics experts with prior knowledge of the systems, found that ANS did not provide a unique capability relative to the other systems evaluated with respect to basic navigation functionality. However, the Red Team noted that ANS was designed for and had demonstrated capabilities for operating in an off-road environment, unlike some of the other systems. The Red Team, which had previously witnessed demonstrations of some of the systems, did not conduct field evaluations for the study due to time constraints, nor did the team rely on testing data and reports on the different systems.
