After North Korea failed satellite launch is more calls for ballistic missile defence system.
Frank Rose, Deputy Assistant Secretary of State for space and defence policy in the US said: "There is a need for a phased adaptive approach to missile defence."
"Missile defence plays an important role in the broader US international security strategy, supporting both deterrence and diplomacy." Rose said:
"This missile defence architecture will feature deployments of increasingly-capable sea- and land-based missile interceptors, primarily upgraded versions of the Standard Missile-3 (SM-3), and a range of sensors in Europe to defend against the growing ballistic missile threats," added Rose.
He pointed out: "This phased approach develops the capability to augment protection against long-range ballistic missile threats, and to offer more effective defences against more near-term ballistic missile threats."
North Korea fired a long-range rocket Friday and aborted 90-second flight of a three-stage rocket far shy of what’s necessary to reach orbit suggested that North Korea hasn’t yet perfected a weapons system capable of reaching the United States.
