Launcher was acquired by Vast in February 2023.

Launcher’s operations are now focused on developing the E-2 liquid rocket engine as a product available for sale to launch vehicle companies. E-2 is a LOX/Kerosene oxidizer-rich staged combustion engine that is expected to be the most efficient rocket engine for small launch vehicles.
