Perry Technologies, an operating unit of Lockheed & Martin, built
a DIVE TANK to conduct underwater filming and studies in complete darkness by lowering a
submersible though the top of the 55 foot diameter tank.
D.S. Sewing worked closely with Perry Technologies to build the
right cover for their Dive Tank. We used durable 40 oz. vinyl coated polyester fabric,
designed with a slit for a submersible to enter the tank with a crane.
