Exos Aerospace is focused on suborbital research rockets with an intent of initially launching micro satellites and eventually progressing to autonomous spaceflight.

The SARGE vehicle employs a LOX-ethanol propulsion module based on the LE23000FC series engines, producing approximately 5500 lbs of thrust.

Pressurized helium cold gas thrusters provide attitude control for pitch-roll-yaw and pointing capability.

Exos plans to use this technology as the design basis for a reusable (first stage) launch vehicle capable of carrying 100 kg to low Earth orbit.

On 14 February 2018, the Federal Aviation Administration issued Exos Aerospace a Reusable Vehicle Mission Launch License.

On 25 August 2018, Exos flew an unsuccessful Pathfinder Mission proving SARGE as a reusable launch vehicle.

Due to a malfunction of an onboard GPS receiver, the flight was terminated with an engine shutdown prematurely.

On 29 June 2019, at 18:00, UTC Exos Aerospace conducted a SARGE launch at the Spaceport America in New Mexico.

Second, the rocket appears to have disintegrated to some degree as several pieces of debris fell back to the ground.
