Delta History

[@scottmanley]

History of the delta is one of those projects I’ve never quite finished, great to see this version with all the archive footage.

[@MrHichammohsen1]

The centaur upper stage was introduced to me by you sir, thank you.

Scott, see my longer comment.

[@anonymousperson2110]

​@@orbitalair2103 In case OrbitalAir's comment gets buried, here's his comment: "I was there, in 1989 at LC17, as Thiokol Project engineer, I was there to help McDac fit the air start solids nozzle insulators. The SRBs were Thiokol CastorIVAs made in Huntsville Alabama by a team of dedicated engineers and manufacturing folks, with over 22,000lbs of solid propellant each. 6 were Ground started, 3 were lit in the air. I think Thiokol/McDonnel-Douglas and the Air Force were a great team then. " The above is a copy+paste of OrbitalAir's comment, not mine. BTW cool job orbitalair.

I just hate that when some famous KZbinr posts a comment everybody likes it even without reading

orbitalair, that is so cool

Great!

The Delta IV Heavy was an incredible rocket that has served it's purpose. Can't wait to see Vulcan fly!

[@peteparker7396]

MrMichaelXX one more launch to go for the heavy! It’s sitting on the pad at SLC 37A

[@MrAzazel666]

@@peteparker7396 Oh really? I wasn't aware of that. I though the Heavy was already retired. Thanks for the info!

[@javiervazquez2815]

MrMichaelXX only the Medium is retired. The Delta IV Heavy still has 5 more launches to go, 3 from The Cape and 2 from Vandenberg. Expected retirement is in 2024

[@MrAzazel666]

@@javiervazquez2815 Thanks for the info. I looked it up and I must've got confused about the Delta Medium. Definitely exciting that I've got 5 more launches to look forward to!

[@jk20404a]

Delta 4 Heavy is the coolest orange rocket !

[@pictobloxer5412]

Wait till u see sls >:]

[@alrightydave]

SLS: Am I a joke to you? Honestly though jokes aside I genuinely do like SLS a whole lot more than DIV H, 4 times more capable for only double the price

[@lovaravonimanantsoa8583]

All this could be realized without an outstanding Teamwork of highly skilled engineers, technicians, scientists and innovators.

[@toamastar]

Wow! Amazing video! I had no idea there was this much history attached to your rockets! Loved it! :)

[@Justin_Martin]

Delta History is awesome 🇺🇸👑💕

[@javiervazquez2815]

I love the Delta IV Heavy 🔥 the first rocket I ever watched launch then I got more interested in many rockets

[@MrHichammohsen1]

Amazing as usual. Go team space!

[@StarshipFairing]

Yay go ULA

[@starship1128]

Legendary

[@stevengaming3689]

ICE SAT is done. Delta II is no more. :(

[@danielalejandroochoaalvare590]

I like the Delta II.

[@aliciasematore4285]

6:24 First Delta 4 Rocket Launch!

[@itroll8638]

I really believe ULA has dinosaur age designs just my opinion

[@coffeespy1133]

So?

[@vvvvvvk6495]

I am waiting for the new Vulcan rocket fly! COME ON! ULA

[@cowboybob7093]

All the domestic competition in launch, but different abilities Is New Glenn going to become the space-station module vehicle? - Huge LEO and not hot GTO Falcon 9 similar but lower Vulcan with that centaur (efficient, flexible, reliable) may have GTO covered (but price?)

[@sevenrubberducks5450]

Can’t wait till 70 years later until we see Vulcan centaur history

[@williamduffy1227]

NASA should have used Delta IV to put Orion into orbit, but Mike Griffin was more interested in making money for his friends at ATK/Morton Thiokol.

[@tonk2629]

Delta IV heavy can only put it in orbit, not on a trans-lunar injection

[@williamduffy1227]

@@tonk2629 It wouldn't have to do the T.L.I. burn. Orion could have been launched on Delta IV Heavy, the Aquila lander and TLI booster could have been on SLS.

[@tonk2629]

@@williamduffy1227 You do realize the SLS Block 1B and Block 2 have rideshare payload capacity, right? they could easily fit a lander in it.

[@williamduffy1227]

@@tonk2629 - Yes, they do have extra capacity. By putting Orion on a separate rocket though you can put a larger 4 man lander and the "3rd" stage~ TLI booster on the SLS Block 2. I don't know if SLS could put even more mass than that in a GTO (?) orbit. This idea would be like the former Constellation program with a Delta 4 Heavy standing in for the ill-fated Ares 1 rocket. I do realize that they aren't making Delta 4 rockets anymore. I also don't know how to do the calculations that would be necessary to make this work. 😄 I'm just having fun day dreaming about other possible 'architectures'. ✌🖖

[@docnathan3959]

Basically an fully expendable version of the Falcon Heavy.

[@gunnykido7213]

Yea, but i think it either has slighly more or slightly less performance

[@gunnykido7213]

Falcon heavy has a lot better performance if used in fully expendable mode

[@emman.5995]

Nah. Falcon Heavy is a reusable Delta IV Heavy.

[@Delta-V-Heavy]

Falcon Heavy has more performance to Low Earth Orbit, however, Delta IV Heavy has a more efficient upper stage, giving it an advantage when launching to destinations beyond LEO. A somewhat moot point as there are only a few Delta launches left. Sad to see this orange beast go.

[@fratkara1445]

Koçum ben hep pozitifim ama rezaletlede karşılaşırsam çok sinirlenirim.

[@AsphaltAntelope]

My favourite one was when the ULA rocket landed!! And then was reused!!! I joke. My favourite was the fully original rocket that ULA designed from scratch. Edit... it's just a gentle joke guys. That was a good video :) What's the overall success rate of all Deltas? Must be high 90%s ?

Damn you hit ula hard Lol
