As far as I can remember, use of this large fairing was previously on physically large payioads, like the X-37, or when 3 or more solids were used because the exposed Centaur stage couldn't sustain the aerodynamic loads if I understand correctly.  Are the payloads that big and require the big fairing?

The last 4-meter Atlas V fairing launched aboard the JPSS-2 mission last year, so there were no 4-meter fairings left to utilize for this launch. (If the 2 satellites could fit in a 4-meter fairing)

Launch at 18:06:00?  Seeking launch time to the second or fraction thereof; I realize that Amazon is being secretive.

T+40 minutes. The Centaur upper stage should now be reigniting its RL-10 engine to head to a solar disposal orbit.

With this much excessive secrecy, what would have the coverage been like for Cert-1?

United Launch Alliance Successfully Launches First Mission in Partnership with Amazon
October 6, 2023

Atlas V precisely delivers initial Project Kuiper prototype satellites.

Cape Canaveral Space Force Station, Fla., (October 6, 2023) – A United Launch Alliance (ULA) Atlas V rocket carrying the Protoflight mission for Amazon’s Project Kuiper lifted off on Oct. 6 at 2:06 p.m. EDT from Space Launch Complex-41 at Cape Canaveral Space Force Station. To date, ULA has launched 158 times with 100 percent mission success. The Protoflight launch is the first mission in a broader commercial partnership between ULA and Amazon to launch the majority of the Project Kuiper constellation.   

“This initial launch is the first step in support of deployment of Amazon’s initiative to provide fast, affordable broadband service to unserved and underserved communities around the world,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “We have worked diligently in partnership with the Project Kuiper team to launch this important mission that will help connect the world. We look forward to continuing and building on the partnership for future missions.”

ULA’s next launch is the inaugural Vulcan mission from Cape Canaveral Space Force Station in Florida. The next generation Vulcan rocket will offer unprecedented flexibility in a single system with streamlined operations and greater affordability, while continuing to provide unmatched reliability and orbital precision.

As far as I can remember, use of this large fairing was previously on physically large payioads, like the X-37, or when 3 or more solids were used because the exposed Centaur stage couldn't sustain the aerodynamic loads if I understand correctly.  Are the payloads that big and require the big fairing?

I don’t think they have any 4 meter fairing left after JPSS-2 launch last November. Would not be surprised if the production line is already closed.

Launch at 18:06:00?  Seeking launch time to the second or fraction thereof; I realize that Amazon is being secretive.

From my memory regarding ULA launches, if the Launch Director doesn’t specify the seconds while instructing the “Timer” team member to set the clock post-polling, it’s assumed the T-0 is set at :00.

Looking through my images and this shot is just the chef’s kiss.

I can only imagine what a Vulcan rocket would look like inflight.

Liftoff of the Atlas V 501 carrying Amazon’s first prototype Kuiper satellites into orbit!

Seeing the Atlas V without its solids was a little strange, but it’s slow ascent was really something to take in!

Congrats to ULA on another professional "making it look easy" launch and Amazon on finally getting their first two Kuiper satellites into space!

The secrecy thing is whatever, I imagine ULA folks were keeping an expressionless face while mentally rolling their eyes.

I love seeing nature meet machine. And what a machine the Atlas V is, successfully sending the first Amazon Kuiper internet satellites into space!
