SpaceX Conducts Super Heavy Static Fire With 33 Raptor 3 Engines for Starship Flight 13

SpaceX completed a critical static fire test of its Starship Super Heavy Booster 20 on July 10, 2026, igniting all 33 upgraded Raptor 3 engines. This successful test marks a significant milestone, potentially clearing the path for the upcoming Starship Flight 13, which could launch as early as July 15. The event took place at SpaceX’s Starbase facility in Boca Chica, Texas, demonstrating the readiness of the booster for its next major flight.

The Super Heavy Booster 20, a crucial component of the Starship mega-rocket, underwent a roughly 25-second engine burn. This duration is designed to simulate the conditions of an actual launch while the booster remains secured to the launch stand. The test is a standard pre-flight procedure to verify the performance and health of the engines and associated systems.

Test Overview and Results

The static fire test of the **SpaceX Super Heavy Booster 20** involved the simultaneous ignition of all 33 Raptor 3 engines. This test aimed to validate the booster’s propulsion system and ensure its operational readiness for flight. The successful completion of the test on July 10, 2026, indicates that the booster performed as expected.

The 25-second burn allowed SpaceX engineers to collect extensive data on engine thrust, performance, and stability. This data is crucial for assessing the booster’s ability to withstand the stresses of launch and maintain control. It serves as a vital step in the rigorous testing regimen for Starship before it attempts orbital flight.

Raptor 3 Engine Upgrades

Booster 20 is equipped with SpaceX’s upgraded **Raptor 3 engines**, representing a significant advancement in propulsion technology. These engines are designed to provide increased thrust and efficiency compared to previous versions, contributing to the overall power of the Starship system. This particular booster is the second «Version 3» (V3) booster to undergo testing at Starbase.

The Raptor 3 engines are full-flow staged combustion cycle engines, using liquid methane and liquid oxygen as propellants. This design enables high performance and reusability, critical features for SpaceX’s long-term goals for lunar and Martian missions. The successful static fire confirms the functional integration of these advanced engines within the Super Heavy booster.

Starship Flight 13 Timeline and Launch Window

The successful static fire test has paved the way for Starship’s 13th test flight, designated as Flight 13. According to a notice from the Federal Aviation Administration (FAA), the earliest potential launch date for this mission is Wednesday, July 15. This rapid turnaround from static fire to potential launch highlights SpaceX’s agile development and testing philosophy.

The Starship system, comprising the Super Heavy booster and the Starship upper stage, is designed for rapid reusability and high payload capacity. Each test flight gathers crucial data to refine the vehicle’s design and operational procedures, moving closer to regular commercial and exploration missions. Further updates on the exact launch timing will be provided by SpaceX as approvals are finalized.

Pre-Launch Preparations

Preparations for the static fire test began well in advance, with Booster 20 transported to the launch pad at Starbase on July 9. The massive booster was then hoisted onto its support stand using the launch tower’s «Mechazilla» chopstick arms, a distinctive feature of the Starbase launch facility. These arms are designed to both stack the vehicle and catch it upon return.

On the day of the test, July 10, SpaceX initiated a series of prelaunch procedures. These included the closure of Boca Chica beach around 8 a.m. EDT (1200 GMT) and the transfer of fuel to the pad’s tank farm in preparation for propellant loading onto the vehicle. These measures are standard safety protocols implemented during critical test operations.

Mission Context: What’s Next for Starship

The successful static fire of **SpaceX Super Heavy Booster 20** is a crucial step for the ongoing development of the Starship program. Each test, including this static fire and the anticipated Flight 13, gathers vital data necessary for iterating on the design and operational sequences of the fully reusable launch system. The ultimate goal for Starship is to enable human missions to the Moon and Mars, as well as facilitate satellite deployment and rapid point-to-point travel on Earth.

The progress seen with the Raptor 3 engines and the V3 booster configuration demonstrates SpaceX’s sustained efforts to enhance Starship’s performance and reliability. The company’s transparency in testing, often shared via platforms like X, provides insight into these developments.

FAQ: What is a static fire test?

A static fire test is a critical pre-flight procedure where a rocket’s engines are ignited while the vehicle remains secured to the launch pad. The purpose is to verify engine performance, structural integrity, and system readiness without actually launching the rocket. This allows engineers to identify and address any issues before flight.

FAQ: What is «Mechazilla»?

«Mechazilla» is the informal name given to the large arm structure on the Starship launch tower at Starbase. These arms are used for stacking the Super Heavy booster and Starship upper stage components. In the future, they are also intended to catch the Super Heavy booster upon its return to the launch site, facilitating rapid reusability.
