The ATACMS Block 2 initially had problems with the submunition's (BAT) acoustic sensors picking up too much background noise and causing less than
adequate performance during tests and evaluations. (Something like a 50% kill ratio)
Although there were some discussions to change from the BATs to the LOCAAS submunition which uses a LADAR instead of acoustic and IR sensors, it
seems most of the issues with the BAT submunition have been successfully handled.
The poor performance mixed with the ATACMS's cost which is just shy of 1 million dollars for a missile fully loaded with 13 BATs, nearly got it
cancelled, but the system somehow survived.
The First Unit Equipped (FUE) is on schedule for early 2005, upgraded software for AFATDS to calculate fire missions for ATACMS block II and block IIa
became available in spring of 2004. The BAT has been upgraded to BAT P3I.
