(by William Cole, Honolulu Star Advertiser) — The Sea-Based X-Band Radar (SBX)* has deployed out of Pearl Harbor after North Korean dictator Kim Jong Un recently said his country was in the “final stages” of test-launching an intercontinental ballistic missile (ICBM). [*The SBX is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the Missile Defense Agency’s Ballistic Missile Defense System.]
Dispatching the “SBX” out to sea sends “a very clear strategic message of deterrence to the ICBM threat of the North Korean leader that has intensified since first announced on Jan. 1,” said Riki Ellison, chairman of the Missile Defense Advocacy Alliance, a Virginia-based nonprofit that advocates a strong U.S. missile defense.
Media sources reported that the SBX was being sent about 2,000 miles northwest of Hawaii to watch for a possible North Korean launch in coming months. The Pentagon downplayed the floating radar’s Monday departure.
“The SBX’s current deployment is not based on any credible threat; however, we cannot discuss specifics for this particular mission while it is underway,” Navy Cmdr. Gary Ross, a Defense Department spokesman, said in an email.
Kim Jong Un said in a Jan. 1 speech that North Korea was prepping for an ICBM test launch.
“The SBX deployed in the Pacific Ocean enhances and boosts the probability of kill for each of the current 37 and soon to be 44 (ground-based interceptors) in both Alaska and California, if fired at a North Korean ICBM,” Ellison said Thursday in an MDAA release.
If the North Korean test ICBM does not target U.S. or allied territory, the SBX would be in a position “to collect invaluable precision data on the warhead and debris of a North Korean ICBM test-flying in space,” the release said.
Defense Secretary Ash Carter also suggested this week that the United States might just monitor the launch if it didn’t appear to be a threat.
The more than 280-foot-tall SBX is topped by a golf ball-like dome containing a phased array radar and is a hard-to-miss sight at its mooring off Ford Island. The powerful radar, which is only operated at sea, acquires, tracks and discriminates the flight characteristics of ballistic missiles.
Both the White House and State Department have said that North Korea hasn’t yet demonstrated the ability to miniaturize a nuclear warhead and put it on an ICBM.
“But we do know that he (Kim) continues to want to have those capabilities” and that his programs “continue to march in that direction,” State Department spokesman John Kirby said Jan. 3.
South Korean media previously reported that the SBX radar was deployed in late September to an area off the Korean Peninsula. Concerns over North Korea’s nuclear program led to the deployment of the SBX in 2009 and 2013, according to the Union of Concerned Scientists.
The group said in a July report that the $2.2 billion SBX is designed for long-range precision tracking and discrimination of warheads from other objects, but it “has a number of serious limitations, including a very limited electronic field of view.”
Based on shortcomings of the SBX, the U.S. Department of Defense’s Missile Defense Agency announced plans to develop by 2020 a long-range discrimination radar in Alaska, the scientific group said.
Ellison said North Korea has tested six long-range rockets since 1998 with speeds similar to an ICBM. North Korea said a launch in February 2016 was intended to put a satellite in orbit.
“North Korea most likely wants to demonstrate through this (upcoming) test its warhead design and the re-entry capability of a successful ICBM launch in order to validate its strategic nuclear force,” Ellison said.

BALLISTIC MISSILE and DEFENSE:
A ballistic missile is a missile that follows a sub-orbital ballistic flightpath with the objective of delivering one or more warheads (often nuclear) to a predetermined target. The missile is only guided during the relatively brief initial powered phase of flight and its course is subsequently governed by the laws of orbital mechanics and ballistics. To date, ballistic missiles have been propelled during powered flight by chemical rocket engines of various types. (from wikipedia/Ballistic_missile)
An intercontinental ballistic missile (ICBM) is a guided ballistic missile with a minimum range of 3,400 miles – primarily designed for nuclear weapons delivery [delivering one or more thermonuclear warheads] wikipedia/Intercontinental_ballistic_missile
- National missile defense (NMD) as a generic term is a type of missile defense: a military strategy and associated systems to shield an entire country against incoming Intercontinental Ballistic Missiles (ICBMs) or alternately more short-range ballistic missiles. The missiles could be intercepted by anti-ballistic missiles, or possibly by lasers. They could be intercepted near the launch point (boost phase), during flight through space (mid-course phase), or during atmospheric descent (terminal phase).
- Missile defense is a system, weapon, or technology involved in the detection, tracking, interception and destruction of attacking missiles. Originally conceived as a defense against nuclear-armed ICBMs, its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.
- an anti-ballistic missile (ABM) is a missile designed to counter ballistic missiles (a missile for missile defense; an interceptor). A ballistic missile is used to deliver nuclear, chemical, biological or conventional warheads in a ballistic flight trajectory. The term “anti-ballistic missile” [interceptor] describes any antimissile system designed to counter ballistic missiles. However the term is used more commonly for ABM systems designed to counter long range, nuclear-armed Intercontinental ballistic missiles (ICBMs). (from wikipedia)
THE U.S. MISSILE-DEFENSE SYSTEM:
The Strategic Defense Initiative (SDI) was proposed by U.S. President Ronald Reagan on March 23, 1983 to use ground-based and space-based systems to protect the United States from attack by strategic nuclear ballistic missiles. The SDI was intended to defend the United States from attack from Soviet ICBMs by intercepting the missiles at various phases of their flight.
The initiative focused on strategic defense rather than the prior strategic offense doctrine of mutual assured destruction (MAD), that assumed that neither side would start a nuclear war because it would not be able to avoid imminent destruction. Reagan’s “Star Wars” program drew the Soviets into a costly effort to mount a response. The race depleted Soviet funds and triggered the economic difficulties that led to the collapse of the Soviet Union in 1991. (Many in the media and liberal circles ridiculed President Reagan for being a warmonger AND a dunce; they did not understand the necessity of a missile defense system).
