The Royal Naval Air Service (RNAS) was the air arm of the British Royal Navy, established in 1914. It played a crucial role during World War I, providing aerial support for naval operations and conducting reconnaissance missions. The RNAS operated various aircraft, including seaplanes and landplanes, to enhance naval capabilities. In 1918, the RNAS merged with the Royal Flying Corps to form the Royal Air Force (RAF), marking a significant shift in military aviation. The RNAS's contributions laid the groundwork for modern naval aviation and influenced the development of future air services within the British military.
