context_page_description: The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedoes are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A increased its shallow-water performance. The Mark 46 was initially developed as REsearch TORpedo Concept I, one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare.
