When Tory Bruno, the CEO of [United Launch Alliance](https://www.ulalaunch.com/) ([ULA](https://www.ulalaunch.com/)), talks about optimizing rockets for “high-energy” versus being optimized for “low-energy”, [he is referring to the capabilities and design priorities of different launch vehicles.](https://medium.com/@ToryBrunoULA/the-secrets-of-rocket-design-revealed-e2c7fc89694c)

[Key points:](https://spacenews.com/bruno-trumpets-transformation-of-ula-after-vulcan-launch/)

- Bruno argues that [ULA](https://www.ulalaunch.com/)’s Vulcan rocket is a “high-energy” rocket designed for demanding missions like direct injection of payloads into geostationary orbit. He contrasts this with “low-energy” rockets that he says are “hyperoptimized” for launching spacecraft into low Earth orbit (LEO).
- He claims that for high-energy missions, Vulcan is about 34% cheaper than [SpaceX](https://www.spacex.com/)’s offerings, implying [SpaceX](https://www.spacex.com/)’s rockets are more optimized for LEO.
- However, Bruno also acknowledges that nearly half of Vulcan’s current launch backlog is for Amazon’s Project Kuiper, which is a large LEO constellation. This seems to contradict his point about Vulcan being mainly for high-energy missions.
- Bruno emphasizes that rockets are engineering machines targeted at specific tasks, and that different rockets are suited for different applications, cautioning against having a “favorite rocket”.

When discussing optimizing for “high-energy” vs “low-energy”, Tory Bruno is highlighting that [ULA](https://www.ulalaunch.com/) has designed Vulcan to excel at challenging high-energy trajectories to distant orbits, while suggesting that competitors like [SpaceX](https://www.spacex.com/) have rockets more optimized for high-volume LEO satellite deployments. However, Vulcan will still serve a mix of high-energy and LEO missions.
