Seals made from neoprene rubber were developed for use in the launching system of advanced-design Polaris missiles. The function of the seals is to contain the gas pressure in the annular space between the missile and the tube during launching. Ten different cross-sectional contours were studied by tests on reduced-size seals, and the contour best meeting the requirements for load versus clearance and sealing ability was selected for large scale testing. Seals of the selected contour and neoprene stock were manufactured and installed in the 57 inch-ID Peashooter launch tube at San Francisco Naval Shipyard. The seals functioned very satsifactorily during a trial launching of a dummy Polaris missile.
