However, the needs of today?s military in the ever-changing worldwide environment have begun to reveal the C-141B?s age. In recent years, threats to the United States national security have increased the immediacy of replacing the C-141B with an aircraft that meets the current needs of our military, yet is flexible enough to meet future needs as well.

With its four engines each producing 40,500 pounds of thrust, the C-17 is capable of a maximum speed of 515 mph and a service ceiling of 45,000 feet. Its powerful engines allow the C-17 to use a runway only 3,000 feet long. By comparison, the C-141B?s four engines produce only 20,250 pounds of thrust. This limits the aircraft to
