US Congress again attacks stand-off weapon's reliability following technical problems Glitches are again threatening the future of the stealthy Lockheed Martin AGM-158 Joint Air-to-Surface Standoff Missile (JASSM), prompting a new showdown with Congress and a renewed US Air Force focus on manufacturing improvements. USAF officials earlier this year cleared the low-cost weapon to enter full-rate production, after overruling concerns raised in an annual report by the US Defense Department's office of test and evaluation by asserting that a series of technical problems that had reduced the missile's reliability had been fully resolved. A new string of unrelated technical glitches has surfaced during the three most recent tests. On 8 June, the mission planning system for a Northrop Grumman B-2A stealth bomber malfunctioned, aborting a JASSM live fire test before it could begin.
