Members of Division C of the Army Contracting Command - Aberdeen Proving Ground, Md. and the Program Executive Office, Intelligence Electronic Warfare and Sensors, celebrated a milestone - one million flight hours with the Persistent Threat Detection System in support of combat missions in Iraq and Afghanistan.

The ACC-APG members made this milestone possible through the award of multiple PTDS contracts and task orders valued at more than $1 billion. Contracts awarded and administered by ACC-APG enabled assembly and testing of the integrated aerostats, sensors, ground stations and mooring systems in support of PEO- IEW&S and its product manager for meteorological and target identification capabilities, located at APG.

The one million mission hours supported the Department of Defense in Operations Iraqi Freedom, New Dawn, and Enduring Freedom. The flight hours were recorded from 2004 to February 2014.

"The PTDS is a large aerostat-based system tethered to a mooring platform and is equipped with both visual and audio surveillance technology," said Gregory L. Davies, Chief of ACC-APG's Division C. "PTDS acts as a force multiplier for commanders on the ground and can be used to scan large areas of terrain for potential insurgent activity while interacting with various other sensors to give a complete picture of potential threats. Aerostats are lighter-than-air systems that provide long-endurance communications and surveillance capabilities."
