Not an expert, but I'm betting NONE of the Delta IV is reusable.

IOW, 16 different rockets of the design "Delta IV" have flown, not the same rocket 16 times.

Scrubbed.

Problem at T-3:58.

High pucker factor.

Tune in tomorrow.

Right, it’s not reusable. This is not the 16th launch of one rocket, but the 16th launch of this model.

But I’m curious how they developed a new model and only launched that model 16 times.

That's why the Delta IV is a failure. Lots of negative reporting on SpaceX when their first few flights of Starship and its booster ended up in the ships being lost, calling the flights failures.

According to that type of reporting, then most other rockets flown were failures, because they were all expendable, not reusable, and were lost. SpaceX changed the game, but reporters don't realize it.
