The next flight of United Launch Alliance’s triple-barrel Delta 4-Heavy rocket has been delayed from June to late August, military officials said Friday.

A United Launch Alliance Atlas 5 rocket, flying in its basic two-stage configuration with no strap-on solids, was stacked aboard a mobile launch platform at Cape Canaveral’s Vertical Integration Facility on Feb. 22 and 23 in preparation to send Orbital ATK’s S.S. John Glenn cargo ship into orbit for the International Space Station.
