The ACTD will be conducted in two parts: Phase III proposals address adverse-weather, precision guidance technologies as well as advanced sensor technologies to support target characterization and battle damage assessment (BDA); Phase IV will address development of alternative payloads, including high-temperature incendiaries and agent defeat warheads, to mitigate chemical and biological agents. (Phases I and II are conducted under Counterproliferation I ACTD). Both phases will continue to enhance the capabilities of the integrated weapons of mass destruction (WMD) planning tools developed during CP ACTD I. The specific WMD targets to be addressed during the CP II ACTD will be based on the supported CINC's priorities within his area of responsibility. CP ACTD Phases I and II provided basic WMD planning tools, a hard-target smart fuse, and an advanced penetration bomb that essentially provided the capability to deliver an effective high-explosive warhead against soft to moderately hard WMD targets from the surface down to approximately 20 ft below the surface. Phase III (FY98-FY00) will provide sensor and weapon technologies to more accurately characterize the WMD target to allow more precise selection of a three-dimensional aimpoint, allow precision delivery of the weapon under adverse weather conditions, and provide more accurate and timely BDA data for restrike decisions. The weapon technology is precision delivery using inertial terrain-aided guidance to provide highly accurate standoff delivery to selected aimpoints under almost all weather conditions. The sensor technologies involve chemical, biological, and electromagnetic unattended ground sensors (UGS) as well as three-dimensional seismic/acoustic UGS for both target characterization and BDA. They also include FLIR pod modifications that more accurately provide hitpoint determination, high/low order and in/out of cavity detonation determination, potential size of cavity, and type of agent expelled data for BDA. A weapon-borne sensor is also envisioned that will provide underground structural data as well as fuze function data. Phase IV (FY00-02) will provide alternative payloads to provide options other than high explosive to functionally defeat WMD chemical and biological material.

Under DOE sponsorship, Lawrence Livermore National Laboratory has already developed the critical enabling technologies for this DTO: sensors capable of detecting clandestinely transported nuclear weapons/materials, and the algorithms needed to reliably detect (with low false alarm rates) and track the movement of such threats. Initial priorities in this DTO are to develop and demonstrate fieldable prototypes of these capabilities. This will include work on system engineering design for the initial fielded capability and refinement of a concept of operation for use of this capability by a warfighting organization. The key technical challenge in the field will be to achieve high levels of detection and tracking with low levels of false alarms. Sensor technologies are highly sensitive; there is more background and point-specific radiation in the environment than is sometimes appreciated.

Follow-on phases will refine the fielded capability, and include tests against simulated clandestine threats. The leave-behind capability will be a system for wide-area detection of clandestine nuclear/radiological threats. Depending on what is learned during field trials, this capability may be integrated with the Airbase/Port Bio Detection ACTD product or the DSWA Corral Monitoring System.

As a new capability redressing a major shortfall in current warfighter resources, this effort does not lend itself to quantification of benefits; the baseline is zero. The Joint Staff is involved in the effort as a customer representative. The identity of specific warfighting organization customers is sensitive information.
