In collaboration with the Department of Defense’s Joint Improvised Explosive Device Defeat Organization (JIEDDO), DARPA initiated the Vehicle and Dismount Exploitation Radar (VADER) program to design and deploy a radar system for unmanned aerial vehicles (UAVs) or small manned aircraft. Developed for DARPA by Northrop Grumman Electronic Systems, VADER provided synthetic aperture radar and ground moving-target indicator data to detect, localize, and track vehicles and dismounted troops.

The ARPA Vela program developed sensors to detect nuclear explosions in space, the upper atmosphere, and underwater to support the 1963 Limited Nuclear Test Ban Treaty, under which the United States, Great Britain, and the Soviet Union banned atmospheric tests of nuclear weapons. The first VELA sensors, deployed on a pair of satellites launched three days after the treaty was signed, were designed to monitor for optical and electromagnetic signatures of nuclear explosions in the atmosphere.

Later in the 1960s and 1970s, DARPA oversaw the development of the World Wide Standardized Seismograph Network (WWSSN) for detecting underground nuclear tests. The Agency also helped expand detection technologies globally and internationally by running workshops, funding research projects in other countries, and championing community-building initiatives.

Traumatic Brain Injury (TBI) is the signature wound of conflicts in Iraq and Afghanistan. Conservative estimates put the number of U.S. warfighters who have experienced TBI at more than 200,000. Battlefield medical personnel today rely on visual signs and the personal accounts of patients to alert them to the possibility of TBI. The DARPA Blast Gauge provides a quantitative means for measuring blast related exposure, thus providing a mechanism for medical personnel to better identify those at risk for TBI. The gauge collects quantitative data to provide medics with a screening tool and data for uncovering the mechanisms of TBI.

Today, cost and complexity limit the Navy to fewer weapons systems and platforms, so resources are strained to operate over vast maritime areas. Unmanned systems and sensors are commonly envisioned to fill coverage gaps and deliver action at a distance. However, for all of the advances in sensing, autonomy, and unmanned platforms in recent years, the usefulness of such technology becomes academic when faced with the question, “How do you get the systems there?” DARPA’s Upward Falling Payloads program seeks to address that challenge.
