In addition to USSOCOM, both the Army and Marine Corps have explored using UA to deliver material in high threat/risk environments. The Army's Medical Corps examined employing small UA to deliver urgent medical supplies to forward areas in a recent ACTD (Quick Meds).  The Marine Corps converted a K-Max helicopter to unmanned operation for its Broad-area Unmanned Responsive Resupply Operations (BURRO) project that tested ship-to-shore and ship-to-ship resupply in 2000-2002.  Both projects demonstrate that, as forces transition to being more mobile and independent (i.e., less tied to traditional logistics chains), UA offer a viable solution to their accompanying requirement for just-in-time logistics. 
Aerial delivery/resupply summary.  Covert delivery of supplies into denied areas certainly qualifies as an ideal mission for UA under the 'dangerous' rubric.  The mission requirements to fly low and quietly to avoid detection over significant standoff distances and land unaided and precisely can be met with available technologies.  Future technology could best be applied to reducing such systems' probability of detection. In the larger sense, UA could serve as a transformation enabler for the focused logistics needed by future forces.

APPENDIX B:  SENSORS
OVERVIEW
Sensors now represent one of the single largest cost items in an unmanned aircraft; for example, the MTS-A EO/IR sensor, currently being retrofitted to the MQ-1 Predator aircraft, costs nearly as much as the aircraft alone. In a similar fashion, today Global Hawk’s RQ-4 Block 10 Integrated Sensor Suite (ISS) represents over 33 percent of the aircraft’s total cost; with the integration of a multi-int sensor package into the RQ-4 Block 20 model of Global Hawk, the estimated percentage rises to 54 percent.  More demanding operational information needs, such as identifying an individual from standoff distances or detecting subtle, man-made environmental changes that indicate recent enemy activity, demand a higher level of performance than that provided by the current generation of fielded UA sensors.  At the same time the demands placed on UA sensors increase, with commensurate cost increase, UA are also being employed in those exact situations where UA should be used – where there is significant risk for loss of the sensor. As the demand for sensor performance continues to grow, coupled with operational risk to the platform, the need to take steps to control cost growth, as well as to efficiently plan future sensor payloads that take advantage of commonality wherever possible, becomes a “must” for UA acquisition.
Ideally, wherever possible, different UA should use the same sensor systems for similar mission requirements.  When actual system commonality is not possible, perhaps due to size, weight, or power considerations, commonality at the high valued subcomponent level, such as focal arrays, optics, apertures (antennas) or receive/transmit elements for radar systems, can reduce overall sensor costs by increasing the quantity buys of these critical, often high cost items.
