Last refreshed: Apr 16, 2025, 6:33 PM PDT. T-Minus Zero keeps this as the canonical launch record and reconciles schedule, mission, payload, media, and provider signals when those records are available.
Alternate mission URLs consolidate to this canonical launch record so exact mission timing, status, media, and source context stay on one page.
Premium keeps the launch-by-launch change log visible so you can review slips, window edits, and status changes without waiting for an error-driven upgrade prompt.

Use these internal paths to move from this exact launch record into the provider, vehicle, launch-site, schedule, and mission-family pages that own broader context.
This launch currently has no dedicated mission-family hub, so provider, vehicle, site, and canonical record links are the primary internal paths.
Some high-demand launch records carry specialized search intent. These profiles explain what can be verified from the published record without filling gaps that upstream sources have not published.
Published fields only: this page surfaces provider, vehicle, pad, timing, status, source links, and public mission metadata. Payload details may be limited when public sources do not publish them.
Key structured fields for this launch record are grouped here so the page answers mission, payload, orbit, provider, source, and timing questions before the deeper tracking and media sections.
This record is preserved as historical launch context. The page emphasizes what was launched, the vehicle and pad involved, published outcome/status fields, linked programs, and source records instead of treating the mission like an upcoming countdown.

The Minotaur IV launch system is derived from the Peacekeeper ICBM. The first three stages are taken directly from decommissioned Peacekeeper missiles. A fourth stage, the Orion-38, is taken from the Pegasus family of air-launched rockets.
Northrup Grumman Space Systems designs, builds and delivers space, defence and aviation-related systems to customers around the world. They aquired Orbital ATK in 2018 along with its launchers and ongoing missions.
