An interceptor missile test launched Sunday morning was the first successful test since 2008.

The missile launched out of Vanderberg Air Force Base in California intercepted a test missile launched. The interceptor collided with the test missile over the Pacific Ocean. The program has in the past, come under scrutinty for failed tests and high costs. Missile Defense Agency Spokesperson, Rick Lehrner said Sunday's success was key.

"It was a very important step in our efforts to improve the the reliability of our missile defense system," he said.

For Delta Junction near Ft. Greely, the missile defense program has brought in nearly a thousand jobs. According the public information website for Fort Greely, in 1995, the post was barely staffed. It had been downsized as a part of the base realignment and closure process or BRAC. In 2001, it was moved from BRAC status to support missile defense.

Lehner said Alaska has a unique position in the U.S. for missile defense.

"It's an important location of the ballistic system in terms of it's geography in the center of Alaska and it provides a defense from a limited ballistic attack from countries like North Lorea and Iran," Lehner said.

Sen. Lisa Murkowski, R-Alaska has been a proponent of defense missiles at Ft. Greely.

"It is still a challenge in Washington D.C. to make sure that the program and the full commitment moves forward we want to see a full compliment of 40 missiles at Greely," she said.

The most recent test marks what could be a milestone for the future of an Alaskan base.
