Warning: contains spoilers for Star Trek #6!V'Ger, the "villain" of Star Trek: The Motion Picture, has left a long-lasting impression on Starfleet and the Federation. In IDW Publishing’s Star Trek #6, the God City of T'Kon, awakened from a long slumber, is on a collision course for Earth – where it plans to destroy the planet. As the threat approaches, Starfleet mobilizes the fleet, and readers learn of the existence of the "V'Ger Protocols," created for situations just like this.
The text piece does not reveal the V'Ger Protocols in their entirety, but it does share enough details to see they're extreme. When the V'Ger Protocols are enacted, all ships are recalled and all missions canceled; the briefing singles out peacekeeping and research missions. These two types are extremely common for Starfleet vessels, so to suspend them speaks volumes to the wide-ranging nature of the V'Ger Protocols. The V'Ger Protocols are so dire that it takes no one less than the Federation President to enact them.
