The XLR gun is a high energy, high-pressure, large chamber volume, chemical vertical gun system. The gun is capable of 100,000 psi chamber operating pressure; typical guns nominal operate at 60,000 psi. The energy level achievable is 3 times that of fielded guns today. The gun can launch a projectile at speeds above 4,500 mph. (MACH 6).The XLR possesses many features which produce a unique design. The design innovations resulted in a modular gun design; long, segmented barrel; top chamber loading; a turntable for support two chambers; a separable chamber, and a replaceable chambrage sealing cartridge.The gun system consists of two major assemblies. The first is the cannon assembly, which comprises of the barrel/chamber connector, recoil cylinders, barrel support structure and barrel segments. The second is the turntable, which contains the chambers and projectile rammersSeparable Chamber (shown in yellow)Chambrage Seal Cartridge
8Design - Modular Test Gun Upgrades During Phase III, the XLR design became modular. Since the design used a separable chamber and segmented barrels, a variety of gun configurations are permissible. Different volume chambers could be used to optimize a prop charge for a given projectile and increase gun performance. Mono-bloc barrels are used so that varying barrels could be used and to make the barrels interchangeable.Three configurations were designed. Gun performance could be increased by adding additional (modular) hardware.The recoil cylinders are sized to handle the recoiling forces of each configuration; replacing them is not necessary.

The XLR innovations and unique features resulted in a modular gun design. Its modular provides its flexibility and adaptability to an ever-changing DoD environment. The XLR’s modularity is its advantage over other test guns. The table below briefly describes the XLR’s features, advantages and benefits.
