What Does FSF Stand For?

FSF stands for First Static Firing

FSF, or First Static Firing, refers to the initial test of a rocket engine or propulsion system while it is securely mounted to a test stand. This critical phase assesses the engine's performance and stability without the risk of flight, allowing engineers to gather essential data on thrust, fuel flow, and combustion characteristics. The results from the FSF are fundamental to validating design specifications and ensuring the reliability of the propulsion system for future launches.
