When the war broke out the Naval Wing of the Royal Flying Corps had already been separated from the Military Wing, and had become the Royal Naval Air Service. Captain Murray Sueter was Director of the Air Department, and Captain G. M. Paine was Commandant of the Central Flying School. Six officers, all pioneers of the air, held the rank of wing commander, and nineteen held the rank of squadron commander. There were twelve flight commanders, and, with the addition of some few who joined on the 5th and 6th of August, there were ninety-one flight lieutenants, flight sub-lieutenants, and warrant officers. The number of petty officers and men was approximately seven hundred. Some of the officers and men had been appointed for special duties in connexion with gunnery, torpedo work, navigation, wireless telegraphy, and engineering. The duties which fell to the Royal Naval Air Service were naturally more various and more complicated than those which fell to the Royal Flying Corps. The Naval Air Service had to fly seaplanes and airships, as well as aeroplanes. They had made more progress than the Military Wing in fitting wireless telegraphy and in arming aircraft. They had in their possession, when war broke out, thirty-nine aeroplanes and fifty-two seaplanes, of which about half were ready for immediate use. They had also seven airships, of which one, the little Willows airship, may be left out of the reckoning, but of the others, the _Parseval_, _Astra-Torres_, and _Beta_ did good work in the war. Some of the aeroplanes and most of the seaplanes were fitted with more powerful engines than any that were used by the Royal Flying Corps. Engines of two hundred horse-power were being installed in Short, Wight, and Sopwith seaplanes, with a view not chiefly to speed but to the carrying of torpedoes. These machines were not successful at first, but experiment was active. Two aeroplanes and one airship had been fitted with machine-guns; petrol incendiary bombs had been tried with success; and gear for the release of bombs was being gradually improved. More important still, wireless telegraphy plants had been set up at the various seaplane stations on the coast, and sixteen seaplanes, operating in connexion with these stations, had been fitted with transmitting apparatus.
