Arcturus Half Electric Engine

The Arcturus Half Electric Engine (aka Arcturus Engine or Arcturus Half Electric Engine) is an engine that uses methalox and electricity at the same time. It will be implemented in future rockets, like Alpha Delta Gen III. It will be implemented in the Antares Half Electric Rocket. Starting on January 14th, 2026, we will go fully electric with the Achernar Electric Rocket and then the Alpha Delta Gen IV, however, we will still but rarely use non electric rockets until their End of Support date on October 14th, 2027, and also half electric rockets until late 2028. We will conduct simulations and experiments with the Arcturus Engine 2 days before it's release.
