Does TERCOM become less accurate with range?
A TERCOM system considerably increases the accuracy of a missile compared with inertial navigation systems (INS). The increased accuracy allows a TERCOM-equipped missile to fly closer to obstacles and generally lower altitudes, making it harder to detect by ground radar.
How do fire and forget missiles work?
The missile has a “fire and forget” principle of operation. It means the missile guidance does not require further guidance after the launch and still hit the target without the launcher being in line-of-sight of the target. So now you know why India’s obvious enemies do not want to wage a war with the country.
What is the range for a Tomahawk missile?
about 1,500 miles
The Tomahawk is a long-range, unmanned weapon with an accuracy of about 5 metres (16 feet). The 5.6-metre- (18.4-foot-) long missile has a range of up to approximately 2,400 km (about 1,500 miles) and can travel as fast as 885 km (550 miles) per hour.
How does a TERCOM system improve missile accuracy?
It uses a pre-recorded contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter. A TERCOM system considerably increases the accuracy of a missile compared with inertial navigation systems (INS).
When was the Tomahawk cruise missile launched in Yemen?
On 13 October 2016 five Tomahawk cruise missiles were launched by USS Nitze at three radar sites in Yemen held by Houthi rebels in response to anti-ship missiles fired at US Navy ships the day before.
When was the ground launched cruise missile withdrawn from service?
Ground-launched cruise missiles (GLCM) and their truck-like launch vehicles were employed at bases in Europe; they were withdrawn from service to comply with the 1987 Intermediate-Range Nuclear Forces Treaty. Many of the anti-ship versions were converted into TLAMs at the end of the Cold War.
How is Terrain Contour Matching used in cruise missiles?
Terrain Contour Matching, or TERCOM, is a navigation system used primarily by cruise missiles. It uses a pre-recorded contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter.
