should attach the ring directly to the towline, and then
to the target-release device of the aircraft.
Klein "Chicago" Grip
The Klein "Chicago" grip (fig. 8-7) provides a
means of transferring the target drag load from the reel
to a structural member of the towing aircraft. This
procedure is used to take the strain off the reel while the
target is streamed.
The grip is a standard commercial item. It is about
10 inches long and composed of a series of
spring-loaded linkages and a shackle. Compressing the
entire grip in line with the extended shackle opens the
jaws. It will grip bare wires, solid or stranded, from
0.081 to 0.162 inch in diameter.
A cable to the aircraft’s internal structure first
secures the grip. Then, it is attached to the tow cable
near the outrigger sheave. Slightly unwinding the reel
transfers the load from the reel to the grip. The greater
the drag load, the tighter the jaws grip the cable.
CAUTION
Do NOT apply loads greater than 1,500
pounds to the grip. It will accept cable with a
much greater breaking strength than that of
the grip itself. As a safety measure, set the
reel brake while the grip is in use, keep the
clutch in the IN position, and keep the slack
in the tow cable between the grip and reel at
a minimum.

AERIAL TARGETS
LEARNING OBJECTIVE: Identify aerial
targets to include the missile target, target
drone, and target system.
The Navy uses three aerial targets—the AQM-37C
missile
target,
BQM-74C/E
target
drone,
and
BQM-34A/S and BQM-34E/T target system. A
simplified discussion of aerial targets is presented in
this section of the NRTC.
