ULA has announced a planned date for the next Vulcan mission, return to service nine months after the Space Force grounded the vehicle after the February 12, 2026 launch of the fourth Vulcan mission. The date is Friday, November 13th - yes, "Friday the 13th."
The return-to-flight mission will launch 40 satellites for the Amazon Leo broadband constellation, the first of 38 Vulcan flights Amazon has booked to deploy the bulk of its network. The mission will lift off from Cape Canaveral Space Force Station, Florida, and ULA said the launch date is pending range approval.
The launch is critical for ULA after its new flagship rocket suffered nozzle failures on its solid rocket boosters on two of its first four missions, most recently during a flight in February. In both cases, the rocket overcame the nozzle failure and completed its mission, but officials at the US Space Force, ULA’s primary customer, lost confidence in Vulcan.
The mission is in the NextSpaceflight line up already (IIRC, earlier in the week, it said, "NET November") where NET is the standard abbreviation for No Earlier Than. It does not include a liftoff time.
As much as this mission is critical for ULA, demonstrating that their vehicle is trustworthy, it's critical for their customers - both Amazon Leo and US Space Force. The Pentagon has tasked ULA with around half of their classified launches through the early 2030s. The Space Force certified the Vulcan in 2025, then flew the two missions on which the Solid Rocket Boosters' nozzle failures occurred. The second failure triggered grounding the vehicle until it passes tests.
In a statement, United Launch Alliance said engineers “made great strides” in understanding the booster anomaly that occurred in February. Engineers “have identified several potential contributors, which have been mitigated through design and process improvements to the nozzle,” ULA said.
ULA also said, “To support our customers, this upcoming launch will utilize the improved nozzle design, and additional testing and analysis will continue in parallel with the mission. By flying the improved design, ULA gains valuable flight data that validates these improvements and is the most beneficial path in support of all our customers.”
Vulcan has a very full agenda in front of it. The Amazon LEO constellation is far from the extent of it - you might recall that SpaceX and ULA were chosen by Space Force to launch classified missions, with a contract that will actively swap missions between the two providers. That means in a case like this, Space Force may be moving payloads that they view as more critical to SpaceX and they'll tell SpaceX which future mission on their schedule to move to ULA in trade - more or less.
For example:
A launch carrying the Air Force Research Laboratory’s Oracle-M lunar mission will now fly on SpaceX’s Falcon Heavy rocket instead of ULA’s Vulcan, which will receive a future SpaceX-assigned launch in compensation. Space Systems Command completed a similar swap to move a large strategic missile warning satellite from Vulcan to Falcon Heavy.
So far the swaps have had no effect on the number of missions the Space Force has awarded to ULA and SpaceX. The trades are separate from the Space Force’s assignment of unallocated future missions to launch providers, which may already be hamstrung by SpaceX’s plans to retire the Falcon rocket family.

The next launch (two weeks from this Friday) will be the first Vulcan to fly with six SRBs. That increases the chances of getting a bad booster nozzle (if it really was a random 1 of 4 chance on the previous two failures). They plan on two flights before Vulcan could be certified again.
