I wonder if the trick is something like "launches in the same configuration" because that would really penalize older rockets that used to undergo upgrades once in a while.
- Rebelgecko 6y agoI don't know if there's an official definition, but I'd consider the Delta IV and Delta IV Heavy to be separate launch vehicles in the same family, akin to the Falcon 9 and Falcon Heavy. Whereas with the single-stick Delta IV Medium, the variations like 4m vs 5m fairings are just different configurations.
