Air Force certified Falcon Heavy for national security launch but more work needed to meet...

A SpaceX Falcon Heavy on June 25 launched the Defense Department’s Space Test Program-2 mission with 24 satellites.

Although STP-2 was a U.S.government-funded space launch managed by the Air Force, it was not a National Security Space Launch mission. The NSSL program launches the nation’s most valuable and least risk-tolerant satellites for the military and the intelligence community.
