A platform for servicing of vertically positioned missiles in a ballistic ssile submarine. The platform includes a vertically inclined rail and a horizontal frame. In the frame there is a first element having a first and a second end superimposed over the inclined rail. This first element is movably mounted directly on the rail at the first end and movably mounted in vertically spaced relation above said inclined rail at said second end. At least one second element is spaced laterally from the first element to enclose a missile tube access opening. A vertical support means is also positioned in opposed relation to the inclined rail. The vertical support means is adjustable to the curved hull surface of the submarine to maintain the frame horizontal. The platform is constructed from a lightweight material such as aluminum, and it can be carried and assembled by two men for the efficient servicing of VLS equipped submarines and other similar vessels.

Two man loading platform for use on submarines

The present invention relates to a method for preparing a titanium or titum alloy surface and a primer for use in the method. The method broadly comprises the steps of grit blasting portions of the surface to which an adhesive will be applied and thereafter applying an acid wash primer to the surface portions. The acid wash primer preferably consists essentially of 70% by weight isopropyl alcohol, 5% by weight ethyl alcohol, 15% by weight n-butyl alcohol, 5% by weight zinc chromate and 5% by weight phosphoric acid.
