Blackwater Blimps

The Blackwater Airships team completed design work at the end of 2006 and is now building the Polar 400 airship. This highly capable RPAV will provide a platform ready to accomodate a wide variety of state-of-the-art surveillance, communications and detection equipment that can record and store events and downlink them in real-time to ground operators.

We've all heard of black helicopters. The video in the previous post actually contains footage of one. But black airships? This whole article is most informative.
