The Starship Spacecraft SN25 combined with Super Heavy Booster B20 stood on the launch pad, it was the fourth Starship prepared for the full-stack launch test.
According to the latest naming standards issued by SpaceX, the complete system will be named as SS (StarShip) + number, so this one should be called SS-4.

Including the first-stage SL-X rocket delivered to NACA, they produced a total of 301 Raptor V1 engines this year, averaging a Raptor engine coming off the assembly line every 29 hours.
All of this, apart from Musk's bold slogan "one Starship a month," was more importantly due to the covert technical support and large number of orders from NACA since last year, with the Starship Town manufacturing Starships about to complete its second major upgrade.
