A rocket delivered by cargo ship to Vandenberg Air Force Base was unloaded on Thursday.
The United Launch Alliance Delta IV rocket came from a production facility in Alabama via the MV Mariner.
The 30th Space Wing posted a time-lapse video of the rocket's arrival and the subsequent offloading by Air Force personnel at Vandenberg's dock, which was specially built to receive deliveries from the ship.
Officials say the rocket had to be delivered by boat because it's so large. No word on a launch date for the massive rocket.
