The latest THAAD missile flight test out at the Pacific Missile Range Facility (PMRF) on Hawaii has unfortunately had yet another target failure preventing the testing of the system:

A planned test of the Terminal High Altitude Area Defense (THAAD) system scheduled to be conducted from the Pacific Missile Range Facility, Barking Sands, Kauai, Hawaii, was not able to be completed today due to an anomaly with the target missile.

The target missile was successfully deployed from a C-17 transport aircraft but the target’s rocket motor did not ignite. The THAAD interceptor missile was not launched; however, the system’s fire control system conducted a number of successful simulations. All THAAD system components were verified to be in working order, and the system was ready to conduct the mission.

Program officials will conduct an extensive investigation to determine the cause of the anomaly.  [MDA Webpage]

THAAD FTT-10 was cancelled back in September 2008 due to a target failure and the FTT was rescheduled and this time successfully executed back in April 2009.  No word from MDA when FTT-11 will be rescheduled.
