Still, said Jordan, it would be a big mistake to stop producing tanks."Look, (the plant) is in the 4th Congressional District and my job is to represent the 4th Congressional District, so I understand that," he said. "But the fact remains, if it was not in the best interests of the national defense for the United States of America, then you would not see me supporting it like we do." The tanks that Congress is requiring the Army to buy aren't brand new. Earlier models are being outfitted with a sophisticated suite of electronics that gives the vehicles better microprocessors, color flat panel displays, a more capable communications system, and other improvements. The upgraded tanks cost about $7.5 million each, according to the Army. Out of a fleet of nearly 2,400 tanks, roughly two-thirds are the improved versions, which the Army refers to with a moniker that befits their heft: the M1A2SEPv2, and service officials said they have plenty of them. "The Army is on record saying we do not require any additional M1A2s," Davis Welch, deputy director of the Army budget office, said this month. The tank fleet, on average, is less than 3 years old. The Abrams is named after Gen. Creighton Abrams, one of the top tank commanders during World War II and a former Army chief of staff. The Army's plan was to stop buying tanks until 2017, when production of a newly designed Abrams would begin. Orders for Abrams tanks from U.S. allies help fill the gap created by the loss of tanks for the Army, according to service officials, but congressional proponents of the program feared there would not be enough international business to keep the Abrams line going. This pause in tank production for the U.S. would allow the Army to spend its money on research and development work for the new and improved model, said Ashley Givens, a spokeswoman for the Army's Ground Combat Systems office.
