CAPE CANAVERAL SPACE FORCE STATION, FL – After several weather related delays and for only the fourth time the ULA Vulcan Centaur rocket is planned to lift off on Thursday, Feb. 12 on a national security mission for the US Space Force from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida
The ULA Vulcan will be carrying the USSF-87 mission for the United States Space Force’s Space Systems Command (SSC) to a near-geosynchronous orbit supporting the U.S. Space Command space surveillance operations.

“GSSAP is a space-based capability operating in a near-geosynchronous orbit supporting the U.S. Space Command space surveillance operations as dedicated Space Surveillance Network (SSN) sensors. The demonstration system is designed to test new technologies to enhance resiliency and protection for future programs of record.”
A two-hour launch window is planned for Feb. 12, 2026 between 3:30-5:30 a.m. EST (12:30-2:30 a.m. PST).
