Abstract: A "float-up" launching system for launching missiles from submerged submarines or other submerged launchers utilizing a lightweight rigid cylindrical tube telescoped over the missile while stored in the launcher so as to not take up additional volume. On launching, the tube is extended forward of the missile by a gas generator to form a floatation chamber which creates extra buoyance forward of the missile center of gravity, but still connected to the water surface, nose upwardly, where it is disconnected and the missile booster is ignited.

Abstract: A solid fuel rocket in which the rocket casing acts as a warhead. Solid propellant rocket motors require relatively heavy cases to contain the 1000-2000 psi combustion pressure needed for efficient performance. This casing can be used as a fragmentation warhead by forming longitudinal grooves in the elongated rocket casing, causing the casing to fracture along the grooves and allowing the pressure within the casing to disperse the fragments. The resulting strip-like fragments are particularly useful against "soft" equipment targets, such as anti-vehicle and anti-radar applications. Several different methods for rupturing the case along spaced, parallel longitudinal lines are disclosed. This system eliminates the need for a separate warhead including case and explosive at the cost of a slight increase in propellant case thickness and weight.
