Ballistic Missiles

What is Ballistic Missiles?

A ballistic missile is a rocket-propelled weapon that follows a ballistic trajectory to deliver a payload, often an explosive warhead, to a target. These missiles are guided during their initial powered phase but then follow a free-falling trajectory influenced by gravity and air resistance. Ballistic missiles are categorized by their range: short-range (less than 1,000 km), medium-range (1,000-3,000 km), intermediate-range (3,000-5,500 km), and intercontinental (over 5,500 km). They can be launched from land-based platforms, submarines, or aircraft. The accuracy of a ballistic missile is measured by its Circular Error Probable (CEP), which is the radius around the target within which the missile is expected to land 50% of the time. Ballistic missiles are a key component of many nations' defense strategies.

Historical Background

The development of ballistic missiles began in the 1930s with Nazi Germany's V-2 rocket during World War II. After the war, the United States and the Soviet Union captured German scientists and technology, leading to rapid advancements in missile technology during the Cold War. The development of Intercontinental Ballistic Missiles (ICBMs) in the 1950s and 1960s created a nuclear standoff between the superpowers. The Strategic Arms Limitation Talks (SALT) and Strategic Arms Reduction Treaties (START) aimed to limit the production and deployment of these weapons. In recent decades, countries like China, India, and North Korea have developed their own ballistic missile capabilities. The ongoing development and proliferation of ballistic missiles remain a significant concern for international security.
