Seriously, this thing has always underperformed tests, and now the lot 6 acceptance tests for the Joint Air-to-Surface Standoff Missile (JASSM) have been deferred. (paid subscription required)
This thing has never performed as reliably as the specs require, and cancellation for cause would be a good way to kick a defense contractor in the teeth for delivering crap, and then expecting the taxpayer to fund the fixes.
Sometimes, you have to do stuff like this prevent this sort of behavior from becoming endemic in the defense procurement process.
