In testimony before lawmakers yesterday, David Duma, OSD’s Principal Deputy Director for Operational Testing and Evaluation (OT&E), detailed failings of the Army’s Non-Line of Sight Launch System (NLOS-LS).
During the most recent tests carried out in February, new navigation software caused six of seven total system aborts. Overall missile reliability is just 61 percent, well below the 85 percent requirement. The missile’s problems appear to be with its infrared seeker; missiles using the IR seeker hit only 5 out of 11 times during tests last year and again this year.
During limited user tests in February, the first operational flight test of the NLOS-LS, only two of the Precision Attack Munition missiles fired hit their targets; two missiles impacted more than 14 kilometers from the target.
The Army has identified some of the problems, including data misinterpretation by the missile’s onboard computer, motor problems and a circuit board failure. OSD recommended that the Army conduct more flight tests once the problems have been corrected.
Army Lt. Gen. Robert Lennox, Deputy Chief of Staff Army G-8, said needed fixes are being made and asked lawmakers for patience and to await further tests.
