19th Century Airship Technology for Port Security

fenimor writes "Airships - known today mainly for advertising flyovers at football games - are the core of a new coastal surveillance system in development for the the U.S. Department of Defense. These stationary platforms 25 times the size of a Goodyear blimp will be equipped with an array of cutting-edge equipment for remote sensing, communications, and risk analysis, providing surveillance coverage over a surface area of 500,000 square miles from an altitude of 70,000 feet."

Almost as good as Anatidocphobia

2005: Somewhere, somehow a blimp is watching YOU!

Currently the USCG employes a pair of blimps "Fat Albert" on Cudjoe Key to watch for dope smugglers, air traffic, etc.

Ob: SovietRussia: For Soviet Russia YOU spy on the blimp!

Cheaper Solutions

[Lev13than]

There are much cheaper alternatives in the works, such as the High Frequency Surface Wave Radar being developed by Raytheon Canada and Defence Research Development Canada.

The big problem with conventional radar is that it only works in line-of-site, but Raytheon's SWR-503 Surface Wave Radar uses high-frequency radar waves that "wrap" around the curvature of the earth. The system has been proven to detect and track aircraft, surface vessels and icebergs out to 500 km from the shore in a sector of up to 120 degrees. Suspicious objects can be investigated by satellite, surface ship, patrol aircraft or very cheaply & covertly via unmanned drone.

Canada plans to install an array of radar installations along the East Coast in order to provide a seamless picture of all maritime activity occuring in the country's economic zone. Similar research is being carried out in the US, Australia and other countries. This seems like a much more effective use of resources than a massive blimp installation
