Project Excalibur was a Lawrence Livermore National Laboratory (LLNL) Cold War–era research program to develop an X-ray laser system as a ballistic missile defense (BMD) for the United States. The concept involved packing large numbers of expendable X-ray lasers around a nuclear device, which would orbit in space.
The missile warhead detonated at 23:30 GMT on May 6, 1962, approximately 1.2 miles (2 km) from the designated target point, and at the target altitude of 11,000 ft (3,400 m). The detonation was successful and had the full design yield of the W47Y1 at approximately 600 kilotons. The shot was designed to improve confidence in the US ballistic ...
Topol-M launch from silo Minuteman III launch from Vandenberg Space Force Base, California, United States of America on 9 February 2023.. An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than 5,500 kilometres (3,400 mi), [1] primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads).
A test-fire of a Hwasong-17 intercontinental ballistic missile (AP) What is a RS-26 Rubezh? According to the Arms Control Association, the RS-26 has a range of 5,800 km and can reach supersonic ...
When Hawaii's ballistic missile threat system blared across the state on January 13, many people didn't know where to go, what to do, or if they could even survive a nuclear attack.
The experiment, part of the Operation Grommet nuclear test series, tested the unique W71 warhead design for the LIM-49 Spartan anti-ballistic missile. [2] [3] With an explosive yield of almost 5 megatons of TNT (21 PJ), the test was the largest underground explosion ever detonated by the United States. [4]
The USA also conducted one live weapons test involving a missile launched nuclear depth charge: Test of the RUR-5 ASROC during the Dominic-Swordfish test on May 11, 1962. The Soviet Union tested nuclear explosives on rockets as part of their development of a localized anti-ballistic missile system in the 1960s. Some of the Soviet nuclear tests ...
The rocket hit speeds of nearly 8,500 miles per hour after it was launched from the 4th Missile Test Range in Russia’s Astrakhan region last month, decimating a military site in Dnipro.
