Centaur integrated on Vulcan as launch-site work advances

  • A LEO-optimized Centaur upper stage has been integrated on a Vulcan rocket.
  • VLP-A is on the pad and undergoing a second phase of technical testing.
  • SLC-3 construction is more than 83% complete, with fuel support tanks installed.
  • VIF-A has achieved Initial Operating Capability, and the OVI cell is structurally complete.
  • A Wet Dress Rehearsal is planned as part of the launch-site work.

What happened

A Centaur upper stage has been integrated on a Vulcan rocket as launch-site preparations advanced.

The Vulcan booster is vertical in VIF-A, while VLP-A is at the pad and undergoing a second phase of technical testing.

What we know

The Centaur upper stage is integrated on the Vulcan rocket and is LEO-optimized.

The Vulcan booster is vertical in VIF-A, and VIF-A has achieved Initial Operating Capability.

VLP-A is positioned on the pad, and the second phase of technical testing is underway.

The VLP has 4 launch heads, and the launch heads are installed.

SLC-3 is more than 83% complete, and construction is well underway.

Fuel support tanks are installed at SLC-3. The smaller tanks are 2 repurposed Atlas ICBM tanks.

The OVI cell is structurally complete. The structural portion of a new roof is complete, and the VIF-A roof is 45 ft.

Why it matters

The updates cover rocket integration, launch-platform testing, and SLC-3 construction, which are key parts of Vulcan launch infrastructure.

For readers tracking the lunar industry, these milestones show progress across the Vulcan vehicle stack, launch platform, and SLC-3 facilities.

What's next

A Wet Dress Rehearsal is planned.
