Project 667A Navaga is a Soviet submarine design project initiated in the 1960s. It aimed to develop a new class of nuclear-powered submarines capable of carrying ballistic missiles. The design focused on enhancing stealth and operational capabilities during the Cold War. The Navaga submarines were characterized by their unique hull shape and advanced sonar systems. They were intended to improve the Soviet Navy's strategic deterrent capabilities against potential adversaries. Although only a few prototypes were built, the project contributed to the evolution of submarine technology during that era.
