So ULA has reduced Vulcan's upper stage to "only" 18,000 hand welds

 

SpaceX uses automated friction stir welding.

Well ... it's an improvement.

 

Baby steps?

BE-4 troubles would fit with the leaks they couldn't get past ~70% throttle.

Boeing-Lockheed's Vulcan rocket design 'nearly fully mature'

 

CAPE CANAVERAL, Fla. (Reuters) - A joint venture between Boeing Co and Lockheed Martin Corp will conduct the final design review for its new flagship Vulcan rocket within months, it said on Wednesday, as the aerospace company heads for a showdown with Elon Musk's SpaceX and others in the launch services market.

The final design review is a crucial milestone as the company, United Launch Alliance (ULA), tries to move into full production ahead of a first flight in spring 2021 after slipping from its initial 2019 timetable.

"The design is nearly fully mature,"  ULA systems test engineer Dane Drefke told Reuters during a tour of Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

Meanwhile, Blue Origin has hit "a few minor setbacks" during rigorous BE-4 testing but was "progressing nominally" and was expected to live up to delivery targets, Drefke said.

Blue Origin did not immediately respond to a request for comment.
