A regenerative liquid propellant rocket motor including a body having an integrally formed central tube. A primary combustion chamber is disposed in the body. A secondary combustion chamber is formed by the central tube of the body. A reservoir of liquid propellant is disposed in the body. A regenerative piston is slidably disposed in the body for delivering the liquid propellant to the primary and secondary combustion chambers. The piston includes a plurality of injection ports for injecting the liquid propellant. An ignitor is disposed in the body for initiating combustion of the liquid propellant. A nozzle is formed at a free end of the central tube for producing thrust, wherein upon ignition of the ignitor combustion occurs in the primary combustion chamber driving the piston into the liquid propellant reservoir and the liquid propellant is injected into the primary combustion chamber to produce combustion products which are channeled into the secondary combustion chamber and expanded through the nozzle.
