Delta IV Heavy NROL-44 Launch Highlights 

Its first flight was in 2004. It's basically still brand new. Just insanely expensive and obsolete. Falcon heavy can lift 2x more payload mass.

@@jonjonsson4270 the Delta IV Heavy is much cleaner because it burns hydrogen, it's only significant emmision being water

@@theairaccumulator7144 water vapor is also a greenhouse gas

@@belikepanda. but much less then the stuff from falcon 9, infact, it only does water vapor and another stuff which i forgot but is very little

@@theairaccumulator7144 But what about the amount of “rocket” and related toxins that burns up, breaks up and is scattered into the sea? I don’t really care about rocket launch pollutants as I think they are a drop in the bucket in the grand scheme of things. Just wanted to add that to your “is much cleaner” argument.

It’s not that it will run out of engines, it’s going to retire. My top two favorite rockets are AtlasV and Detla, then FH and F9

Finally!

not sure how this was straight to the point🤔

I thought I was the only one who noticed. 😂

@@compi653 I now edited the comment in your name

Two long known problem still exist with SpaceX, one is fairing size, the other is vertical integration. So more reason then just the Air Force love ULA.

@@epsiloneridani7737 These problems are cheap to fix, 300M and you are good to go. I included that in my calculations.

@@muzero2642 if fairing is that cheap to fix then why Elon is not doing it. Also NRO satellites are typically around 1-2B, if it is that cheap why NRO not doing it either? I don’t think they are that dumb.

@@epsiloneridani7737 The returns are not good if you don't have a DoD contract. The sats are built by Lockheed Martin, and ULA is owned by Lockehhed Martin, and the AF is dumb enough not to care. There is no incentive to enable HI.

After the loss of the challenger, the Air Force decided to never rely on one launch vehicle again. This is why the air force bought flights on delta Iv and atlas v. To keep two rocket systems running in case one has a problem. This is the same reason nasa picked two companies for crs, and commercial crew as well.

In the future they might be asking.. "Why didnt they bellyflop down at landing?"

NROL-101 already launched on November 13th

@@javiervazquez2815 sorry I mean NROL-82

Neither, the rocket is moved via rails (between the launchpad and VAB) or via transport.

It's the VAB that moves.

It’s classified so broadcast kind of just stop after stage separation.

@@epsiloneridani7737 I wonder what kind of secret we could discover by watching 2 seconds of 2nd stage ignition. Unless it's super-secret alien technology or Hydrogen atom throwing nanotechnology?

@@Grama04 Their customer requested it. The customer is the NRO, who paid hundreds of millions of dollars for their satellite to be launched. So I believe the ULA will prioritize their desires over that of a few nerds on the internet who want to see a second stage ignition. If you really want to see that for this rocket, just look up the Parker Solar Probe mission.

@@Jazzmaster1992 I didn't ask why they didn't show ignition. also, trust me there was no such request from NRO. And finally, I watched the Parker Solar Probe mission. Its actually better to succeed at least on 2nd attempt when you got that hundreds of millions of dollars first then think about confidentiality.

Only took 4 tries to get NROL 44 off the pad. NROL 101 did it one it's first try. But that used a different rocket.

17 is the new 44. L17 has been scrubbed ~7 times atm

No, the boosters are not reusable

I see what you you did there. Lol The reason these videos are (to quote someone in these comments) “straight to the point” is that ULA doesn’t care about the boosters since they have these government contracts up the wazoo.
