Defense production refers to the manufacturing and supply of military equipment, weapons, and other materials necessary for national defense. This process involves various industries, including aerospace, electronics, and materials science, working together to create products that meet the needs of the armed forces. Governments often play a significant role in defense production by funding research and development, establishing contracts with private companies, and ensuring that the military has access to the latest technology. This collaboration helps maintain a country's readiness and capability to respond to potential threats, ensuring national security and stability.
