Arms development refers to the process of designing, creating, and improving weapons and military technology. This includes everything from firearms and ammunition to advanced systems like drones and missile defense. Countries invest in arms development to enhance their national security and maintain a competitive edge in military capabilities. Governments often collaborate with private companies and research institutions to innovate and produce new military technologies. The process is influenced by factors such as international relations, defense budgets, and emerging threats. Arms development can also raise ethical concerns regarding the proliferation of weapons and their impact on global peace.
