A properly designed COPV is about half the weight of a state of the art (titanium) propellant tank of the same volume and pressure rating. Can't beat carbon fiber!
Impulse Space@GoToImpulse· 6 sept. 2024That’s a wrap – another 240-liter composite overwrapped pressure vessel (COPV) meticulously wound with carbon fiber, ready to be cured in our ovens on site. 🔥
COPV tanks are crucial for storing and transporting propellant efficiently. Wrapping them with carbon fiber

Definitely for super high pressure tanks, but a stainless steel Starship is roughly similar in mass to a carbon fiber version (which is where we started out) and way cheaper/easier to make.
Stainless gets that massive bump in strength at cryo and needs much less shielding for hypersonic entry. Hats off to Charlie Bossart and the OG Atlas engineers!
