The U.S Navy uses 1 lb density expanded polystyrene as the base structure for their PETT vessels. The tow targets are pulled behind a remote control boat and used for weapons testing and training. EPS foam is used for buoyancy so the target will stay afloat after multiple hits. The foam is fabricated such that it is removable when it is desired that the boat would sink after being hit. Universal foam Products provides the 1 lb virgin EPS in precut shapes to simplify construction of the realistic looking targets. The Polyethylene Tow Target (PETT) is towed behind a powered remote control boat, and used for weapons testing and training.
