A Short History of Thor/Delta Rocket Evolution

A short history of the evolution of the Thor-Delta family of rockets from Thor-Able to Delta II.

Good evolutionary explanation. I've always admired Thor as a missile and SLV.

[Mike-kron]

Wow, what an amazing video Tyler, loved seeing the changes to the Thor remade in ksp

[cdw]

Those first stage tanks really got to be a mouthful

[eannamcnamara]

I'm designing a stock delta series of rockets and this video is more helpful than any Google search I did. Thanks!

Very well done, I would only add Delta III as well as it had Thor based core, but still, great video

[foxmccloud]

As a young pup, I first heard about the Delta II from a very unusual source. It came from ABC Sports coverage of the PBA Pro Bowlers Tour when they were covering the 1989 Florida Bowlers Journal nearby KSC.

[Earle]

Well done. As one that was there, 1957-1979, That was the best overview I've seen.

Thanks for this informative Video. I think i'll start a Rocket-Line with boosters in my rp-0 game, to compare cost and ability...

One could argue this to be the penultimate American second generation standard rocket; a rocket that was larger in diameter than the 1.65m booster cores on the first generation of rockets (which were directly descended from the German V-2) with new engines, but still needed a very simple, far smaller second stage with storable or solid propellant to reach orbit. The Atlas and Titan did not have that limitation, and thus are arguably third generation, alongside the R-7 (which although still used a Hydrogen Peroxide decomposition startup mechanism, had orbital capability in two stages and employed Kerosene as a fuel instead of Ethanol.

Delta IV would arguably be the world’s first Fourth generation standard rocket, employing a wider core of 5m, being a completely new rocket employing a lighter fuel as a propellant. I’m not sure this is entirely fair however, since Long March 5 has a 5m booster core and Terran R, Neutron and Vulcan all intend to use booster cores with a diameter around 5m. I’m not sure what fuel Neutron uses yet but I’m fairly sure it’s not going to be Kerosene as Beck claimed, and I’m fairly sure he lied about any company actually trying to copy Neutron’s design after Rocket Lab released it.

I have asked this in an older video but idk of you saw it so... can you do a tutorial on how to install ro in 1.3.1 and rp-1?

[jaycemacinnis]

1989-2018 were the years of service for Delta II

[hwce]

Just a quite heads up Altair and Grand Central are diffrent Solid Rocket Motors.

[rkornilo]

Thanks that was really cool.
I just wish Kerbal would upgrade their rocket exhaust visuals. Some of them literally look like the exhaust is leaking out the nozzle (the early Thor).

[Grand-Massive]

So the soviets only started doing hot staging after the US had done in flight ignitions with the AJ-10?

[geryz]

If there was a 5th Delta, it would fittingly also be called Delta-V

[rolfkarlstad]

Can't quite figure out if you are Russian, Finnish, German, or what, but my bet is on the left side. Am I right? =D

[lauratacderan]

IT HAS 9 BOASTERS AND A THOR CORE AND ITS THE TRUE LAST THOR

I want to like this, but it has 69 likes, so, sorry tyler
