wrote in :: Larry -- instead of arguing vague costs and such, can you put numbers on any of this? You claim that a fleet of Cessnas is cheaper than the UAVs, by an order of magnitude. Actually, several orders of magnitude. What are you basing this on? I am curious how you arrived at your conclusion. It's a matter of common sense. It takes only one or two people to operate a Cessna C-182, not SEVEN like it does to operate a UAV. (I am acutally interested in how much these UAVs really cost -- your "several million dollars" figure sounds quite high to me. Then, perhaps you should do some research: http://www.uavforum.com/library/librarian.htm Q: What does a UAV cost to buy? to operate? A: UAVs flying today range in price from $1000 to $14 million. [For comparison, manned aircraft range in price from $20,000 to $500 million.] Examples: The developmental version of the Air Force/Teledyne Ryan RQ-4/Global Hawk costs nearly $14 million with payload, the Air Force/General Atomics RQ-1/Predator $3.3 million with payload, the Navy/PUI RQ-2/Pioneer just over $900,000 with payload. Tactical size UAVs are commercially available in the $250,000 range with payload, the Aerosonde Robotic Aircraft's Atlantic-crossing Aerosonde runs $35,000, and MLB offers mini (not micro) UAVs for around $1000 per aircraft. It is a common mistake to focus on the price of the individual aircraft and confuse it for the price of the UAV system, which includes its ground control station and shelter, launching mechanism, and typically three or more additional aircraft. These can make the price of an UAV system two to ten times the price of its individual aircraft. Once bought and deployed, operating costs are reportedly (Aviation Week & Space Technology, 22 Jun 98, p.23) in the hundreds of dollars an hour for Predator and tactical size UAVs. [For comparison, commercial helicopters cost $600-800 an hour and a Boeing 747 airliner some $7400 an hour.] $10 million unit flyaway price: http://www.rand.org/pubs/monograph_r...1474.chap3.pdf http://www.dtic.mil/descriptivesum/Y...y/0305204N.pdf http://www.rand.org/pubs/monograph_r...1473.chap2.pdf .... Larry Dighera writes: Regardless, the expensive high-tech equipment installed on the UAV is not necessary to locate people illegally entering the US as is born out by the current successful use of video camera equipped model aircraft. Why use model aircraft, when we have seen the successful use of cowboys on horses? First, I'm not suggesting actually using model aircraft for border surveillance. Rather, I am pointing out that cheap, low-tech solutions are currently working, and contrasting that with the obviously dangerous and costly overkill of employing UAVs domestically for this mission. This argument holds no weight unless you can state: That is not the argument I am making. |
