A vice admiral is a high-ranking officer in the naval forces, typically positioned just below an admiral. This rank is often denoted by a two-star insignia and is responsible for commanding large naval fleets or significant naval operations. Vice admirals play a crucial role in strategic planning and decision-making within their respective navies. In many countries, including the United States Navy and Royal Navy, the rank of vice admiral is part of a structured hierarchy that includes ranks such as rear admiral and admiral. Vice admirals may also oversee various naval bases and ensure the readiness of their forces for deployment.
