According to USS Enterprise Owners' Workshop Manual, the Magellan was a Galaxy-class sister ship of the USS Enterprise-D, with a registry of NCC-71820. Dialogue and footage in "Sacrifice of Angels" also supports this, as the USS Venture was previously established as a Galaxy-class ship:
- Sisko: "Ensign, have Galaxy-wings 91 and 93 engage those destroyers. All other ships, head for that opening. Anyone who makes it through doesn't stop until they reach Deep Space 9."
The sebsequent shot was of two Galaxy-class starships attacking a Cardassian destroyer at close range.
- Elim Garak: "Congratulations, Captain. You wanted them angry. They're angry."
- Sisko: "The Magellan and the Venture are supposed to be protecting our starboard flank. They're in too tight..."
