February 10, 2008: Maritime
reconnaissance has been revolutionized with the introduction, and combining, of
lightweight search radars and targeting pods. Two years ago the U.S. Navy began
equipping its carrier based S-3 patrol aircraft with Lantirn targeting pods.
The S-3 was originally designed as an anti-submarine aircraft, and served in
that capacity from its introduction in the mid 1970s, to the late 1990s. The
end of the Cold War ended most of the submarine threat, and since 1999, the S-3
has served as a patrol aircraft, and aerial tanker. In the next decade, the S-3
will be retired, and replaced (for patrol and taker duties) by F-18F aircraft.
But for now, the S-3, with the long range (ten hours per sortie), day/night
video capability of the Lantirn, and lightweight search radar, make it a much
more effective maritime patrol aircraft. The Lantirn pod costs two million
dollars, and is hung off a hard point like a bomb or fuel tank.
The search radar, that can spot ships
fifty or more kilometers away, enable an S-3 to quickly scan a huge chunk of
ocean in a few hours. But the key element here is the targeting pod, which
eliminates the need to fly down low to visually confirm what the ship (that is
easily spotted by the radar) is. With the targeting pod, you can stay high
(20,000 feet) and far away (over twenty kilometers) and still get a close look.
The S-3 can also carry Harpoon anti-ship missiles, in case the ship below is
hostile.
This combination is being used in the
P-3 maritime reconnaissance aircraft, as well as U.S. Air Force B-52 bombers.
The S-3's advantage is that it can operate from an aircraft carrier, enabling a
carrier to quickly establish a detailed picture of what ships are moving in the
vicinity (meaning anything several hundred kilometers from the carrier).
