A payload ejection system (10) for ejecting a payload from a transport vehicle has an ejector mechanism (120) for applying an ejection force to the payload to urge the payload away from the transport vehicle, and a release mechanism for releasing the payload from a restrained state. The release mechanism has a payload mounting bolt (200) for holding the payload in the restrained state, and an actuator (210) that fractures the mounting bolt (200). The actuator (210) has a shape memory alloy, and an activator that transforms the shape memory alloy from a compressed state to an elongated state. The actuator fractures the mounting bolt (200) as the shape memory alloy transforms into the elongated shape.
