Comment: All of the sources here are directly connected to the subject. We require editorially independent sources to demonstrate notability (e.g. a news article or academic journal article).
This page may be helpful in identifying what sources are best. From a cursory search I have identified a few reliable sources (though not many): please use these instead as citations. – Isochrone (talk) 22:04, 2 August 2024 (UTC)

Stoke Space's Full-Flow Staged Combustion (FFSC) Engine is a rocket engine currently under development by Stoke Space. It is planned to be used on the Nova reusable medium lift launch vehicle which will use 7 engines to reach orbit. The engine is a full-flow staged combustion cycle (FFSC) powered by cryogenic liquid methane and liquid oxygen ("methalox")^[1] The Stoke team designed and manufactured the engine within 18 months.^[2]

The engine is comparable in design and intended purpose as SpaceX's Raptor engines.^[3] When flown it is anticipated to be the second full-flow engine ever flown after Raptor.^[4]

Development

In Febuary 2023, Stoke was nearing completion on the test cells for the first stage of Nova in their test facility at Moses Lake, Washington. At this time, Stoke was testing the engine at the component level and anticipating a "Breadboard Engine" test then subsequently assembling the engine into a full package.^[5]

In April 2024, Stoke Space shared photos of the fully assembled engine installed in the test facility. Stoke said the engine went from checkout tests in Kent, Washington to being fully installed at the testing facility in Moses Lake within a single day.^[6]

In June 2024, Stoke Space completed a hotfire test where the engine successfully ramped to it's target power, held power levels, and shutdown without major incident. During the test the engine went from rest to production the equivalent of 350,000 Hp in less than one second. The rest of 2024 was said to be focused on maturing engine and vehicle design while scaling operations for orbital launch.^[7]
