Provides a persistent surveillance and situational awareness capability, allowing quick reaction forces to find, fix, track, target and engage direct or indirect fire threats. PSS-T provides warfighters with an effective intelligence, surveillance and reconnaissance (ISR) capability. In addition to ISR, PSS-T systems provide support to force protection and serve as platforms to extend communications networks beyond line of sight.


Persistent Surveillance Systems-Tethered (PSS-T) is a critical program consisting of tethered aerostats equipped with dual sensor capability that provides high-resolution electro-optic/infrared (EO/IR) capability with dual MX-15 or 20/STARLite /Kestrel payloads and a wide array of other sensors. Video collected by PSS-T is distributed to the forward operating base and division commander information center, as well as to quick reaction forces via personal digital assistant displays, providing tactical commanders enhanced battlefield situational awareness. These systems provide real-time eyes-on-target. PSS-T also provides communications with the command, control, communications, computers, combat systems, intelligence, surveillance, and reconnaissance (C5ISR) aerial layer. The Army provided PSS-T capabilities in support of joint urgent operational needs via overseas contingency operations funding.
