The A/A47U-3A tow target reeling machine-launcher system is an airborne weapon training system. It is used to tow aerial targets for gunnery and aircraft missile firing exercises. The system is a semiautomatic tow-reel and target-launching mechanism externally mounted on the aircraft. The A/A47U-3A system consists of an RMK-19A/A47U-3 reeling machine launcher, a PEK-84/A47U-3 reeling machine-launcher control, and the applicable interconnection cable assemblies. The system uses saddle-mounted aerial targets from 7 to 12.5 inches in diameter that weigh up to 225 pounds. Target towlines, which have constant diameters or stepped diameters with combinations of monofilament and/or stranded wire, are used. The system operates with various towline splices,  ranging in diameter up to 0.250 inch and with flexible lengths up to 106 inches. Typical towlines consist of 10,000 feet of 0.190-inch diameter 3 by 7 stranded steel cable (5,400-pound tensile strength) or 42,000 feet of 0.097-inch diameter 1 by 7 stranded steel cable (2,060-pound tensile strength). The reeling machine-launcher system has a nominal reeling speed capability of 3,500 feet of towline per minute. Adjusting the power unit blade angle limitations increases the speed to a maximum of 5,000 feet per minute. The operator manually controls the system, and it provides launcher up/down, brake on/off, and reel in/out functions. You can control target reeling and recovery speeds by manually adjusting the power unit blade angle. Operation of the system is controlled from the PEK, which is located in the cockpit of the launching aircraft. The A/A47U-4 tow target reeling machine-launcher system is identical to the A/A74U-3A except for weight and size. The lighter weight and smaller size design of the A/A47U-4 was developed to adapt this towing system to a variety of aircraft.
