In addition, it also applies to new construction and operational platforms (ships, submarines, craft, and aircraft etc.), including associated weapon systems and components, as well as shore-based systems that require nuclear survivability. Its nuclear survivability and hardening initiatives encompass development, acquisition, deployment, and support of systems and equipment improvements to prevent or minimize the broad degrading effects of nuclear engagement on mission performance.
