New submitter ripvlan writes: CNN reports that a $700 million mine hunting system created by Lockheed Martin doesn't perform as expected. From the article: "The Remote Minehunting System, or RMS, was developed for the Navy's new littoral combat ship. But the Defense Department's Office of Operational Test & Evaluation says the drone hunting technology was unable to consistently identify and destroy underwater explosives during tests dating back to September 2014. ... In theory, the drone is deployed from the LCS towing sonar detection into suspected underwater minefields. The drone should then identify mines and communicate information about their whereabouts to the ship in real time so the explosives can be avoided or destroyed. But the program has come under fire from lawmakers after a series of testing failures, including continued performance issues and "RMS mission package integration challenges," according to the Defense Department's Office of Operational Test & Evaluation's 2014 annual report."
