The U.S. Navy released its highly anticipated solicitation Jan. 28 to purchase a new training helicopter to replace the aging TH-57B/C fleet.

The USAF may not buy a next-generation low-observable tanker that would support fifth-gen. fighters like the F-35 and F-22, the service’s chief of staff says.
