Bola api pada Roket Delta IV Heavy saat start. Pembakaran ini memang disengaja untuk membakar hidrogen yang dihasilkan dari mesin roket RS-68 agar tidak menjalar ke tempat lain.

Delta IV adalah sistem peluncuran sekali pakai aktif di keluarga roket Delta . Delta IV menggunakan roket yang dirancang oleh Boeing's Integrated Defense Systems division dan dibangun di fasilitas United Launch Alliance (ULA) di Decatur, Alabama . Perakitan akhir selesai di tempat peluncuran oleh ULA. Roket-roket yang dirancang untuk meluncurkan muatan ke orbit untuk program Angkatan Udara Amerika Serikat Evolved Launch Vehicle Expendable (EELV) dan bisnis satelit komersial. Delta IV roket tersedia dalam lima versi: Menengah, Menengah + (4,2), Medium + (5,2), Medium + (5,4), dan berat, yang disesuaikan dengan ukuran payload tertentu dan rentang berat. Delta IV terutama dirancang untuk memenuhi kebutuhan militer AS.

Roket dirakit di fasilitas Integrasi Horizontal untuk meluncurkan dari SLC-37B di Cape Canaveral , dan di fasilitas yang sama untuk peluncuran dari SLC-6 di Pangkalan Angkatan Udara Vandenberg .
