A projectile includes forward and rearward stage motors 12 and 10 respectively, and a boost separation device 11 releasably connecting the two together. The boost separation device includes an impingement plate 17 slidably mounted on the rearward stage motor 10, and a cruciform shaped locking strip element 20 is secured to the deflector plate. The free ends of the arms 21 of the element 20 are received in a groove 27 provided in a rearward portion of the casing of the forward motor. On ignition of the forward motor, its propulsion gases drive plate 17 rearwardly, thus drawing the ends of arms 21 out of the groove 27, thus to allow separation of the rearward stage motor.
