United Launch Alliance is set to kick off its year of 11 planned launches with a mission Friday afternoon for the U.S. Space Force.

The company’s Atlas V rocket is launching two identical satellites into orbit for the Space Force and Department of Defense.

The two satellites will keep a watchful eye on other satellites in space. The Geosynchronous Space Situational Awareness Program (GSSAP) is helping the military track orbital traffic from some 22,300 miles above Earth. The program tracks orbital objects and warns satellite operators if any will pass too closely together, which could be hazardous for orbiting spacecraft.

The launch is targeting a 2 p.m. ET launch window from Cape Canaveral Space Force Station. Forecasters say weather is favorable but meteorologists will keep an eye on cloud cover during the launch window.

ULA says there are 11 launches on its manifest this year. Last year the company launched five missions with a 100 percent success rate.
