The departure at dawn of a United Launch Alliance Atlas 5 rocket from Cape Canaveral Thursday sent aloft the U.S. military’s last Space Based Infrared System missile warning satellite, a $1.2 billion mission billed by the Space Force as a stepping stone to a new generation of more sensitive sentinels in the sky.

United Launch Alliance’s fifth mission of the year lifted off from Cape Canaveral at 6:29 a.m. EDT (1029 GMT) Thursday. An Atlas 5 rocket launched on a $1.2 billion mission with a U.S. Space Force missile warning satellite.

A United Launch Alliance Atlas 5 rocket fired off its launch pad at Cape Canaveral Friday on a six-hour climb to geosynchronous orbit, deploying a classified payload and a U.S. Space Force satellite to test an improved infrared heat-sensitive sensor design that could help detect and track enemy hypersonic missiles.

Officials scrubbed the launch of an Atlas 5 rocket for the U.S. Space Force Thursday due to the risk of lightning from nearby thunderstorms, delaying the liftoff of the $1.1 billon mission until Friday evening.
