Booster 7 and Ship 24 launched for a first integrated flight test on 20 April 2023, planned to fly 3/4 of an orbit and reenter over the ocean near Hawaii. The rocket cleared the launch pad and flew for three minutes but several booster engines failed during the flight and the rocket eventually lost control before stage separation, reaching a maximum altitude of {{Cvt|39|km|mi}}. The [[flight termination system]] was triggered and a subsequent explosion destroyed the vehicle.<ref>{{Cite web |last1=Malik |first1=Tariq |last2=Wall |first2=Mike |date=2023-04-20 |title=SpaceX's 1st Starship launches on epic test flight, explodes in 'rapid unscheduled disassembly' |url=https://www.space.com/spacex-starship-first-space-launch |access-date=2023-11-15 |website=Space.com |language=en}}</ref> The launch broke the concrete pad under the launch mount, resulting in SpaceX replacing it with a water-cooled steel plate for subsequent launches.<ref>{{cite web |title=Why did SpaceX Starship's debut launch cause so much damage to the pad?|website=[[Space.com]] |date=April 24, 2023 |url=https://www.space.com/spacex-starship-damage-starbase-launch-pad|access-date=2023-11-15}}</ref>
