THE LATEST IN SHIP WEAPON LA UNCHERS ‐ THE VERTICAL LAUNCHING SYSTEM

Abstract

ABSTRACTThe primary features of the Vertical Launching System (VLS) planned for initial installation aboard the CG 47 Class (beginning with the CG‐52) and for retrofitting into the DD 963 Class Ships are described in detail. Although modular in construction, the magazine sizes planned replace, with 61 missile cells and an integral strikedown system, the 44 missile MK26 Mod 1 Guided Missile Launching System. The modular concept of the launcher design and the certified round concept, utilizing a sealed canister to protect the missile from weapon station to launch, are described. Design features and development of both the gas management system and the strikedown system are discussed.The engineering development tests which have successfully demonstrated the ability of the launcher to withstand the ignition pressure pulse and absorb the heat of an accidental restrained firing are included as well as those tests which demonstrated performance of the radome after “flythrough” of the exhaust plume.A major advantage of the Vertical Launching System is its ability to engage simultaneously air, surface, and underwater targets. Demonstration tests confirming this capability through vertical launches of the STANDARD, HARPOON, TOMAHAWK, and a modified ASROC missiles are discussed. Two unique test facilities built to minimize development costs are described ‐ one is used to launch and catch the missile intact, providing post test examination and re‐use, and the other duplicates the ship's deck and launcher as well as roll and pitch motion to develop the strikedown equipment and to train the crew.Finally, performance and reliability comparisons are drawn between the Vertical Launching System and current rail‐type launchers.
