With as few as 15 more launches on the calendar over the next five years, the rocket name “Delta” that has been serving the U.S. and international customers since 1960 could permanently fade into history.

Launching the Wideband Global SATCOM 8 satellite for the U.S. military, a United Launch Alliance Delta 4 rocket thundered away from Cape Canaveral at 6:53 p.m. EST (2353 GMT).

The United States Space Force 51 (USSF-51) mission was the 58th and final time an Atlas 5 rocket launches a national security payload. Liftoff happened at Tuesday, July 30, during a three-hour window that opens at 6:45 a.m. EDT (1045 UTC).
