2008: Israel is desperate to get some
kind of anti-missile system in place to protect against rockets being fired out
of Gaza by Hamas. Right now, a top candidate is the U.S. land mobile version of
the Phalanx anti-ship-missile weapon. This system, called "Centurion" was originally developed four years ago,
as "C-RAM". That's why the Israelis want it now, because similar systems
developed in Israel will take several years to perfect, and angry voters will not
give politicians that much time. Centurion is ready now.
Centurion
is basically the Phalanx naval gun system with new software that enables it to take data from its own,
and other, radar systems, and shoot down just about any kind of artillery shell
or rocket within range (about 2,000 meters). It uses high explosive 20mm
shells, that detonate near the target, spraying it with fragments. By the time
these fragments reach the ground, they are generally too small and slow to
injure anyone. At least that's been the experience in Iraq.
The
original Phalanx used 20mm depleted uranium shells, to slice through incoming
missiles. Phalanx fires shells at the rate of 75 per second. Another advantage
of Centurion, is that it makes a distinctive noise when firing, warning people
nearby that a mortar or rocket attack is underway, giving people an opportunity
to duck inside if they are out and about.
The first
C-RAM/Centurion was sent to Iraq in late 2006, to protect the Green Zone (the
large area in Baghdad turned into an American base). It was found that C-RAM
could knock down 70-80 percent of the rockets and mortar shells fired within
range of its cannon. In the last two years, Centurion systems in Iraq have
intercepted over a hundred rockets or mortar shells aimed at the Green Zone.
Not bad, since it only took about a year to develop C-RAM. A Mobile Centurion
system, which can cover an area about four kilometers wide, costs $15 million.
The manufacturer will be turning out four a month.
The
Israelis are also intrigued with a version of Centurion that uses a laser, in
place of the 20mm cannon. This solid state laser has less range (about a
thousand meters) than the 20mm cannon, but can take down more targets in a
short time. Israel has been observed testing the laser itself along the Gaza
security fence, to detonate explosives Hamas has planted on their side of the
fence, to be used against Israeli troops who periodically enter to kill or
capture terrorist leaders.
The short
range of the laser Centurion is not a problem, because there are only a few
places (small towns) in southern Israel that need to be protected from most Hamas
rockets.
