Coinciding with increased tensions with Iran over the resumption of illicit uranium enrichment, the U.S. Air Force has dispatched additional warplanes to the region in a not-so-subtle sign, military sources say. An entire wing of F-16s, the Air National Guard's 122nd Fighter Wing based in Fort Wayne, Ind., left for a base in southwest Asia. A wing is usually about 72 aircraft and several hundred support personnel. F-16s and support personnel from the 4th Fighter Squadron of the 388th Fighter Wing based at Hill Air Force Base, Utah, also deployed recently to Iraq. The squadron has 12 F-16s. Both units' F-16s could be used in any military operation to take out Iranian nuclear facilities. A spokesman for the U.S. Central Command Air Forces, which runs air operations in the region, said the F-16 deployment of about 80 jets is part of a rotation and is not related to Iran's uranium reprocessing.
