An Air Force ballistic missile warning satellite was encapsulated in a protective fairing this week ahead of its Thursday launch from the Space Coast on a United Launch Alliance Atlas V rocket, according to builder Lockheed Martin.

The fourth Space Based Infrared System satellite, labeled SBIRS GEO Flight 4, is scheduled to launch from Cape Canaveral Air Force Station's Launch Complex 41 during a 40-minute window that opens at 7:52 p.m.

The roughly 10,000-pound spacecraft will join a constellation of three other SBIRS satellites more than 22,000 miles above the equator, bolstering the Air Force's ability to detect missile launches and support ballistic missile defense.

Lockheed Martin built SBIRS GEO Flight 4 at its facility in Sunnyvale, California before it was shipped to the Space Coast on Oct. 31.
