The Fairbanks Daily News-Miner reported Thursday the missile installed last month is the 22nd at the Missile Defense Agency site outside Delta Junction.
The Pentagon plans to install 26 of the missiles at Fort Greely by October.
The missiles are part of the Ballistic Missile Defense System and are designed to shoot down enemy warheads in mid-flight outside the Earth's atmosphere.
Fort Greely is one of two sites for the missiles, with three installed at Vandenberg Air Force Base in California, the Missile Defense Agency says.
The new missiles are being installed in silos at Missile Fields No. 2 and No. 3 at Fort Greely. Missiles at the original field, which held six interceptors, are being moved to those fields because of plumbing problems and other reliability concerns at the hastily built early silos, the newspaper said.
