Since November 2002, rockets from the Delta IV Medium family have been launched 29 times, all of which were successful. Its last flight was with a 3rd generation GPS satellite in August 2019.
The Delta IV Medium (also referred to as 'single stick' [1] [2]) was available in four configurations: Medium, Medium+ (4,2), Medium+ (5,2), and Medium+ (5,4). [3]
To encapsulate the satellite payload, a variety of different payload fairings were available. A stretched Delta III 4-meter diameter composite payload fairing was used on 4-meter Medium versions, while an enlarged, 5-meter diameter composite fairing was used on 5-meter Medium versions.
The Medium (4,2) version last flew on 22 August 2019, marking the retirement of the Delta IV Medium variants. [3] [5]
