Production Notes:
-
Surface Naval Gunnery Targets (NavTGTs)
are made from 260 LB rolls of heavy duty 12-mil PVC vinyl film in Orange,
Yellow and Lime Green colors. Submerged skirt bases use Black PVC
film.
-
Each NavTGT balloon is basically a single
very large cell filled with AIR. NavTGTs with a skirt base, water
floods the base to stabilize and anchor the balloon to the surface when
afloat. There is little internal structure.
-
NavTGT balloons are not practical to
be filled with any other substance, particularly not with a chemical foam
which would severely complicate disposal after use.
-
NavTGT balloons are filled using a standard
"leaf blower" type of device or any HVAC, pump, or engine exhaust duct
which can be channeled into the balloon.
-
All air chambers are made using PVC
film. PVC film segments are assembled with a Radio Frequency (RF) welder.
-
Killer Banana™ NavTGTs also have a 2-inch
wide 18-foot long nylon webbing stitched into the multi-layer PolyVinyl
fabric keel attached to the parachute harness D-ring by which it is towed.
Air chambers are then RF welded onto the keel.
-
Bogie Blimp™ airbourne NavTGTs are made
from lightweight PolyUrethane film and are filled with Helium or Hydrogen
gas.
-
NOTICE:
Spent NavTGTs on the surface are a hazard to navigation. After use,
any NavTGT remaining on the surface of the sea must be recovered and recycled.
