The United States Department of Defense (DoD) is engaged in a mission to unify its software systems towards a “net-centric” vision— where commanders gain advantage by rapidly producing, consuming, and sharing information using service oriented architectures (SOAs). In this paper, we study the cyber survivability of mission-critical net-centric systems, focusing on Ballistic-Missile-Defense (BMD...

To ensure that the missile is safely separated from internal weapons bay, jet used to control process of separation, which mounted on front edge bay. The length-to-depth ratio bay was L/D=8, diameter d1 =0.178 m, d2 =0.05 m . FLUENT software combined with our group-developed code under platform a user-defined function (UDF) solve flow field and six-degrees-of-freedom (6DOF) missile. detached ed...

Since the Gulf war, defense missile systems against tactical ballistic missiles have been highlighted and the author also have published some studies. Recently some studies also have appeared, however, it seems that the threat of anti-surface-missiles (ASMs) to current ground sites and its countermeasures have not been sufficiently studied to date.
