Naval Surface Warfare Center Crane Division - Strategic Missions

Strategic Missions

"Deter - Defend - Defeat"

The Strategic Missions Focus Area encompasses the full range of DoD activities that alter an adversary’s will and ability to attack the United States and its interests.

Critical Infrastructure Protection: Crane is the acquisition engineering & technical support agent for the Navy’s Strategic Programs Office for fielding of the Integrated Nuclear Weapons Security System

Full Spectrum Radar Engineering Support: Crane provides a broad range of systems engineering expertise for the sustainment and modernization of the Air Forces Ballistic Missile Early Warning Systems

Flight Systems: Crane supports systems engineering design, analysis, test and evaluation of flight systems for Strategic platforms

Launcher Systems: Crane provides high reliability product and subsystem engineering and logistics to the Navy’s Strategic Systems Programs Strategic Weapons System and Attack Weapon Control System

Famous quotes containing the words strategic and/or missions:

    If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.
    Shoshana Zuboff (b. 1951)

    There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.
    Joseph Heller (b. 1923)
