Today’s dismounted warfighter can be saddled with more than 100 pounds of gear, resulting in physical strain, fatigue and degraded performance. Reducing the load on dismounted warfighters has become a major point of emphasis for defense research and development, because the increasing weight of individual equipment has a negative impact on warfighter readiness. The Army has identified physical overburden as one of its top five science and technology challenges. To help alleviate physical weight on troops, DARPA is developing a four-legged robot, the Legged Squad Support System (LS3), to integrate with a squad of Marines or Soldiers.
The Seeker Cost Transformation (SECTR) program seeks to develop novel weapon terminal sensing and guidance technologies and systems for air-launched, air-delivered weapons. SECTR technologies would enable weapons to acquire fixed and moving targets with only minimal external support; achieve high navigation accuracy in a GPS-denied environment; and be low size, weight, and cost.
During natural or manmade disasters, the U.S. armed forces, with rapidly deployable sealift, airlift, logistics, and medical care capabilities, may be called to supplement lead agencies or organizations providing humanitarian assistance and disaster relief support.
In a target-dense environment, the adversary has the advantage of using sophisticated decoys and background traffic to degrade the effectiveness of existing automatic target recognition (ATR) solutions. Airborne strike operations against relocatable targets require that pilots fly close enough to obtain confirmatory visual identification before weapon release, putting the manned platform at extreme risk. Radar provides a means for imaging ground targets at safer and far greater standoff distances; but the false-alarm rate of both human and machine-based radar image recognition is unacceptably high. Existing ATR algorithms also require impractically large computing resources for airborne applications.  
Today, cost and complexity limit the Navy to fewer weapons systems and platforms, causing strain on resources that must operate over vast maritime areas. Unmanned systems and sensors are commonly envisioned to fill coverage gaps and take action at a distance. However, power and logistics to deliver these systems over vast ocean areas limit their utility. The Upward Falling Payload (UFP) program intends to overcome these barriers.
