The Royal Naval Air Forces, abbreviated as RNAF, is a historical term that refers to the naval air arm of the Royal Navy. Synonyms for RNAF are the Fleet Air Arm, the Royal Navy Air Service, or simply the Naval Air Service. These terms have been used interchangeably since the early days of aviation in the United Kingdom, when the naval aviation branch was formed to support the Royal Navy's operations at sea. Today, the Fleet Air Arm remains an integral part of the Royal Navy, providing air support and carrying out maritime operations across the globe. Thus, these synonyms for the RNAF are still relevant and used in the military context.
