April 3,2008:
The U.S. recently allowed its only Patriot battalion in Europe to hold a
live fire exercise at a firing range on the island of Crete. The targets were four missiles, and
two drone aircraft. All targets were destroyed. Seven PAC-3 missiles (costing $3.3
million each) were fired at the missiles, while three PAC-2 missiles (costing $2
million each) were fired at the unmanned aircraft. In most cases, two missiles
are fired at each target, to ensure a kill. These days, Patriot units are more
concerned with knocking down missiles, than aircraft.
Total
costs of the exercise was over $25 million. For most of the troops involved,
this was the first time they had ever fired an actual missile. Because of the high cost of the missiles,
most training is done with simulated missiles. At the end of the Cold War,
there were six U.S. Patriot battalions in Europe. Most of these have been sent
back to the U.S., or other hot spots (Middle East, Korea).
The
Patriot PAC 2 missiles have a range of 70 kilometers. The Patriot launchers
also fire the smaller (in diameter) PAC 3 anti-missile missiles. A Patriot
launcher can hold sixteen PAC 3 missiles, versus four PAC 2s. A PAC 2 missile
weighs about a ton, a PAC 3 weighs about a third of that. The PAC 3 has a
shorter range, of about 20 kilometers. Each Patriot battalion has 12-24
launchers (3-6 batteries). The PAC 3 was used for the first time during the
2003 invasion of Iraq. The Iraqis fired eleven long range ballistic missiles at
American targets (usually headquarters) and PAC 3 missiles took down eight of
them.
During the
1991 Gulf War, the larger, anti-aircraft version (PAC 2) of the Patriot
missile, modified for use against missiles, knocked down about 70 percent of
the missiles the Iraqis fired. There is still some dispute over this, largely
because the Iraqis had modified their SCUD missiles to give them longer range.
This made the missiles less accurate, and it was difficult to tell if a SCUD
missed because an exploding Patriot warhead
was involved, or simply because that was where the inaccurate missile came
down.
The
Patriot missiles would often hit something, but it was difficult to tell if the
target hit was the warhead or fuselage. That's one reason why two PAC 3s are
fired at each target. In any event, the longer range SCUDs are so inaccurate
that, unless they are being fired at a large target (like a city) they are
unlikely to hit anything valuable. The Iraqis made the increased range
modification during their 1980s war with Iran, when the missiles were fired at
the Iranian capital, Tehran. It's still unclear if the Iraqis even knew of the
"breaking up on re-entry" problem, not that it mattered. As long as their
missile hit somewhere inside Tehran, it was a success.
Shorter
range ballistic missiles rarely use any kind of deceptions, and Pac-3 is pretty
good at stopping them. Longer range missiles come in too fast and sometimes accompanied
by deceptions.
