ULA celebrates the legacy of Delta and salutes the current and former Delta teammates who designed, built, assembled and launched this incredible family of rockets.
My dad, Larry Bradford, worked on the first Deltas through the beginnings of the Delta lV. 44 years beginning with Douglas Aircraft, McDonnell Douglas and Boeing. Over 200 successful Delta 2 launches. Sad to see it come to an end.
Congrats ULA on the tremendous success that (still) is the Delta program and it's successor, the Vulcan. It's great to see so many talented engineer pros work together on such a well designed vehicle :)
I couldn’t agree more. ULA has so many incredibly talented engineers… and they do work really well together. This is a really amazing group, they’ve done so much - and when the final Delta IV launches, they can focus on the remaining Atlas V launches and the ramp up of Vulcan Centaur.
Fair well delta We will tell stories of your heroism and service for many generations to come and we shall wait for your return in popularity in the hall of the heavy lift rockets For a champion has fallen A heavy lifter, a rocket, a friend Long live delta 🫡
They really did my boy Delta 4 like this on its last launch, i am extremely dissapointed wtf, there was no telemetry data, speed, altitute, anything.. Nice going ULA. Treated your best rocket's last launch like💩
ULA isn’t going anywhere… ULA still has some Atlas V vehicles to launch, plus the new Vulcan Centaur, which had its maiden flight on January 8 (a success).
The engines will be saved on Vulcan, but reusable boosters are not always a good idea. The tanks can only take so many pressure cycles, plus the stresses they will endure upon flight and then re-entry will likely lead to failure one day. Also, because reusable booster stages have to carry all that extra weight of the landing equipment (the guide paddles, etc) plus the extra fuel needed to slow the booster descent, really hurts the vehicle performance. The empty tankage is not a big deal, those are easy to manufacture and are not the most expensive part of the rocket. However, Vulcan will be recovering the most expensive part of the entire vehicle - the booster engines - and reusing them. This is a wonderful compromise… it cuts costs significantly and allows the vehicle performance to be maximized. I have never been a fan of reusable booster stages, mainly because as an engineer for decades in the US aerospace industry, I want to see the rocket maximize its performance. This is what will allow ULA to stay one step ahead of its competition… the ability to go farther, higher, etc.

First launch i remember was the Orion test mission, i even had a poster. Can't believe it's going. You'll never be forgotten❤

So much for the team members, past and present, to be proud of when looking at the successes of this program. We will miss you Delta!
Sad to see it go 😭
Delta will still launch cargo from Kerbin.
Fair well delta

For a champion has fallen
A heavy lifter, a rocket, a friend
Long live delta

so cool
godspeed big boi 🫡
Farewell, Delta.

bro, we need reusable boosters!

It's not where you start, it's where you finish.
The rocket is cool, but the nationalistic and militaristic circle-jerk is not.
Farewell Delta IV
Awesome rocket it was🚀, please create an fully reusable SpaceX Starship equivalent ULA 😘🍒
