The Mission

Where ground radar goes blind and satellites have gaps,
an aerostat stays on station.

Borders are vast. Oceans are featureless. Crewed aircraft go home. A tethered aerostat holds a radar at altitude continuously — for days, not sorties — delivering the one thing persistent surveillance actually requires: it never leaves.

What We Build

Aerostats, airships and the radar that rides them.

We do not integrate somebody else's platform. We design, build, fly and sustain our own — including the L-88 radar.

In the Field

“PTDS has come to be a jewel of the collection assets employed.”

LTC David Clonts · Deputy G3 (Acting G3), 1st Cavalry Division

The 74K aerostat carried the Army's persistent surveillance mission through more than a decade of combat operations — flying without propulsion, holding station into the wind, and giving troops on the ground a view that never blinked.
