Fusion Space is announcing the final iteration of Fusion Two ahead of its debut NET March 2026, designed to increase reliability, maximise performance, reduce operating costs, and prepare for Drood spaceflight missions to Luna with the upcoming Nebulon capsule.
F2LG - WIP
The GNC team has been working tirelessly to completely revamp the Fusion Two flight computers to fix several reliability issues and improve functionality. Between December 2025 and January 2026 we have conducted over 50 simulated landings with the new GNC.
The vehicle tanks have been completely redesigned to reduce dry mass and increase propellant capacity, eliminating several void spaces that were present on F2RE, taking us from 430 tons of propellant storage to 450.1 tons.
F2LG - WIP
The overall length of the vehicle has decreased, along with structural reinforcements seeing a reduction in presence, leading to a dry mass of 109 tons on F2RE going down to 75 tons on F2LG. The vehicle stands at 77.5 meters tall.
To accommodate F2LG, we are constructing a new factory that is on track for completion by February 2026 and a new horizontal launch platform is under construction to support the new GSE systems.
Another new addition to F2LG will be the newly upgraded Aeolus V1.7 engine. The vehicle will feature twelve on the first stage and two on the second stage. These engines should see increased reliability and improved lifespans over their predecessors.
F2LG - WIP
In the future, we aim to deploy a common diameter third stage for use with Luna Nebulon flights. This stage is being developed later to reduce the time to launch as teams are working simultaneously to launch both F2LG & Gryphon.
There will be an in-depth performance review released shortly before F2LG's first launch. Thank you for reading. We hope to see you at the launch pad soon!
