Humvee unit cost: $50,000. Fuel efficiency: 14 MPG.
Black Hawk unit cost: $10,100,000. Fuel efficiency: 0.69 MPG. Cost per hour: $1285.82, not including crew.
So we could buy a thousand Blackhawks for ten billion. That's one every 22 miles of border. Assuming a life of 30 years that's 330 million a year. Multiply by ten for crew, maintenance and support, thats 3.3 billion a year.
Big deal.
