The launch infrastructure supporting the Delta IV rocket is about two decades old. Will it ever leave? The company has already retired its basic Boeing Delta IV rocket. And with the launch complex sitting dormant for 364 days a year, there aren't a lot of opportunities to put it through its paces and detect (and fix) launch-canceling glitches before they happen.
On average, ULA has only launched about one Delta IV rocket per year for the past four years. You must login or create an account to comment. See you at the top! Join the Ars Orbital Transmission mailing list to get weekly updates delivered to your inbox.

Pepperidge Farms Remembers. On Tuesday evening, just hours before the company's latest attempt to launch the large Delta IV Heavy booster, the mission was scrubbed again. The company took a few days to fix this problem before setting a new launch date on September 29—Tuesday evening just before midnight.
With the Delta IV's curtain call so near, ULA is said to be focusing on getting nearby LC-41 ready to launch the new Vulcan-Centaur rockets that will replace Delta IV, rather than on keeping LC-37B in tip-top shape. The company has an admirable safety record, and we can be sure they will only launch when everything is ready to go.
Only two of those four flights will take place from Space Launch Complex-37, so the company does not have a great incentive to invest heavily in infrastructure. Since Boeing designed it in 1960, 385 Deltas have launched successfully, including nearly a dozen Delta IV Heavy rockets. Then, a day before the September 26 launch date, the company delayed liftoff again.
"The Delta IV Heavy has only a few launches left, and Space Launch Complex-37 is headed to the graveyard," one Florida-based launch source said. Then, disaster struck again. However, on August 29, everything seemed nominal as the three-core rocket counted down to liftoff from its Florida-based launch pad. Ars notes a few big-picture issues behind the series of nagging little glitches that have kept the NROL-44 grounded.

It only plans to launch three more triple-core Delta IV Heavies (including NROL-44) from LC-37B before that rocket gets retired as well. One launch was scrubbed because of a failed "ground systems regulator," and another for a "pad side stuck regulator" and "torn diaphragm," which ULA CEO Tory Bruno admitted "can occur over time.". ULA initially planned to launch the rocket from Launch Complex-37B (LC-37B) at Cape Canaveral, carrying a spy satellite payload dubbed "NROL-44," back in June 2020.

The good news for Boeing fans is that there's nothing wrong with its Delta rocket design per se -- the contrary is more like it. Local storms caused a delay in pre-launch preparations. A series of technical glitches and weather delays, however, have kept the rocket grounded. Finally, there is the question of the launch pad's future. The weather on Tuesday delayed launch preparations. And when the mobile service tower that supports the rocket began to roll away a few hours before launch, it too had a problem.
The last Delta IV rocket flew from this launch site in August 2019, and the flight rate has only been about one rocket a year since late 2016.
