Intermediate range ballistic missiles, or IRBMs, are missiles that can travel distances between 3,000 and 5,500 kilometers. These missiles are designed to provide a balance between short-range and long-range missiles, and can be used for a variety of purposes, such as conventional or nuclear attacks. Synonyms for IRBMs could include mid-range missiles, intermediate missiles, or mid-range ballistic missiles. These terms all refer to missiles that are capable of traveling a distance between short-range and long-range missiles, and are often used interchangeably with the term IRBM. Understanding the nuances between these synonyms can help military and defense experts better communicate about sophisticated missile systems.
