US military conducts SUCCESSFUL TEST of missile defence system
The US military missile defense agency conducted another successful test of their missile defense system.
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and destruction of attacking missiles.
Originally conceived as a defence against nuclear-armed
Intercontinental ballistic missiles (
ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.
The United States,
Russia,
France,
India, and
Israel have all developed such air defense systems.[1] In the
United States, missile defense was originally the responsibility of the
Army.
The U.S. Missile Defense Agency has developed maritime systems and command and control that will eventually be transferred to the
Navy and
Air Force for operation and sustainment.
History
In the
1950s and
1960s, the term meant defense against strategic (usually nuclear-armed) missiles. The technology mostly centered around detecting offensive launch events and tracking inbound ballistic missiles, but with limited ability to actually defend against the missile.
The Soviet Union achieved the first nonnuclear intercept of a ballistic missile warhead by a missile at the
Sary Shagan antiballistic missile defense test range on 4
March 1961.
Throughout the 1950s and 1960s, the
United States Project Nike air defense program focused initially on bombers, then ballistic missiles. In the 1950s, the first United States anti-ballistic missile system was the
Nike Hercules, which had a limited ability to intercept incoming ballistic missiles, although not ICBMs. This was followed by
Nike Zeus, which using a nuclear warhead could intercept ICBMs. However Nike Zeus had other limitations which prevented it being deployed.[citation needed] In any case, by the early 1960s the Nike Zeus was the first anti-ballistic missile to achieve hit-to-kill (physically colliding with the incoming warhead).
The
Zeus missile was enhanced, and the shorter range
Sprint missile was added to the
Nike defense system, then called Nike-X.
The system included large powerful radars and a computer complex.
Eventually, the Nike-X program was realigned and renamed
Sentinel. This program's goal was to protect major
U.S. cities from a limited
ICBM attack, especially focusing on
China.[2] This in turn reduced tensions with the
Soviet Union, which retained the offensive capability to overwhelm any
U.S. defense.
The Soviet Union deployed the
A-35 anti-ballistic missile system around
Moscow in 1966, which also defended nearby ICBM sites. That system has been upgraded several times and is still operational. The United States announced an
ABM program to protect twelve ICBM sites in 1967.
In 1967, then-Secretary of
Defense Robert McNamara stated: "Let me emphasize – and I cannot do so too strongly – that our decision to go ahead with a limited ABM deployment in no way indicates that we feel an agreement with the Soviet Union on the limitation of strategic nuclear offensive and defensive forces is in any way less urgent or desirable."[3]
The
SALT I talks began in
1969, and led to the
Anti-Ballistic Missile Treaty in
1972, which ultimately limited the U.S. and U.S.
S.R. to one defensive missile site each, with no more than
100 missiles per site.
As a result of the treaty and of technical limitations, along with public opposition to nearby nuclear-armed defensive missiles, the U.S. Sentinel program was redesignated the
Safeguard Program, with the new goal of defending U.S. ICBM sites, not cities. The U.S.
Safeguard system was deployed to defend the
LGM-30 Minuteman ICBMs near
Grand Forks, North Dakota. It was deactivated in
1976 after being operational for less than four months due to a changing political climate plus concern over limited effectiveness, low strategic value, and high operational cost.[citation needed]
In the early
1980s, technology had matured to consider space based missile defense options.
Precision hit-to-kill systems more reliable than the early Nike Zeus were thought possible. With these improvements, the
Reagan Administration promoted the
Strategic Defense Initiative, an ambitious plan to provide a comprehensive defense against an all-out ICBM attack.
Reagan established the
Strategic Defense Initiative Organization (
SDIO), which was later changed to the
Ballistic Missile Defense Organization (
BMDO). In
2002, BMDO's name was changed to its current title, the Missile Defense Agency (
MDA). See
National Missile Defense for additional details. In the early
1990s, missile defense expanded to include tactical missile defense, as seen in the first Gulf War. Although not designed from the outset to intercept tactical missiles, upgrades gave the
Patriot system a limited missile defense capability. The effectiveness of the Patriot system in disabling or destroying incoming Scuds was the subject of
Congressional hearings and reports in 1992.[4]
