Minotaur II rockets consist of the M55A1 first stage and SR19AJ1 second stage of a decommissioned Minuteman missile. The third stage varies depending on the configuration required for the payload: a Minuteman II M57A1 stage is used on the baseline configuration, whilst the Minotaur II+ uses an SR-73-AJ. The Minotaur II Lite is a two-stage configuration, without a third stage. A heavy configuration is also available, with an Orion 50XL third stage, as used on the Minotaur I. The baseline configuration can propel a payload downrange, whilst the heavy configuration can place onto an 8000km (5,000miles) trajectory.

Nine Minotaur II rockets have been launched as of July 2022, with six flights using the baseline configuration and three using the Minotaur II+ configuration. Launches are conducted from Launch Facility 06 (LF-06) and Test Pad 01 (TP-01).
