How accurate are military missiles?

The missiles in many Western militaries can get within a meter of a target with 90 percent accuracy. Precision technology is important because it converts missiles that mainly have psychological impact into cost-effective and more accurate weapons.

How fast are ICBMs?

around 7 km/s.
DEFENSE AGAINST ICBMS. A typical intercontinental ballistic missile (ICBM) will have a range of 8000-10,000 km and a speed of around 7 km/s. Minimum propulsion for a given range is achieved with a reentry angle closer to 22 deg than to 45 deg because the range is not small compared with the radius of the Earth.

Why did the Atlas missile stop being used?

After that time, the Atlas was phased out in favor of Minuteman and Titan ICBM’s. Atlas missiles had to be pressurized while on alert, because the stainless steel shell was so thin—a requirement of flight—that only pressure kept it in place while on the ground.

How accurate was the Atlas D’s guidance system?

The radio guidance system was accurate to one and one-half miles. An Atlas D had a launch response time of approximately fifteen minutes. The Atlas D had two different shelter configurations. The first held the missiles vertically in gantry launchers. The second held the missiles in above ground “coffin” shelters.

Why wasn’t the Atlas ICBM successful?

No prototype had been flight tested, and some skeptics feared that when Atlas’s powerful engines were fired for the first time, the missile’s thin-skinned airframe would buckle in on itself, leaving America’s hopes for an ICBM lying on the launch pad like a gigantic ball of tin foil. General Schriever and his staff were aware of these concerns.

How many stages does the Atlas D missile have?

It was the only one and a half stage missile (for example, the Minuteman has three stages). The Atlas D was 75 feet tall, had a range of 5,500 miles and carried a warhead of 1.44 megatons.
