"The E2 evaluation was conducted in October 2002 using a D5 missile. The modified Mk4 reentry body had an added flap actuator system for control and a GPS-aided Inertial Navigation System (INS). During a substantial part of reentry, GPS reception was lost owing to a plasma-induced blackout. Nevertheless, the flaps deployed and operated as predicted to provide three-axis flight control (roll, yaw, and pitch). Under flap control, the reentry body (RB; see footnote 5, above) was able to turn to its target, and guidance and control were sufficient to steer the RB to the target within several meters of the onboard navigation solution. In other words, the RB came within several meters of where the navigation system calculated that the target was located"

The E2 and LETB flight tests had inert warheads and had a CEP about that of a JDAM.
More interesting is what was proposed for CTM-2. Interesting little UAV stuffed in there.
