This was pretty much the impulse behind carrier aviation. While scouting and spotting were important functions the ability to actually sink other ships with a ship borne aircraft relied on air dropped torpedoes.
Actually it goes back even further than this; the Italians were the first to drop a torpedo like object from an aircraft, although it wasn't an actual torpedo and the RNAS did it the same year, 1914 in June - Arthur Longmore, an Aussie (Oi oi oi!) was piloting the Short seaplane, and senior RNAS and Admiralty staff, including and at the forefront of enthusiasm for the idea, Winston Churchill, who was First Lord at the time. The first proposals for ships carrying torpedo carrying aeroplanes came about in discussions held in 1914 at the time Longmore made his torpedo drop, Churchill even coining the term 'seaplane' as opposed to 'hydro-aeroplane', which was a lot more cumbersome and in use at the time. This is where the navy's use of fast picket steamers for carrying aeroplanes came about and at the outbreak of war, the RN had a number of seaplane tenders that were designed for carrying offensive as well as observation aircraft.
At Christmas time in 1914, the RN launched a raid against German facilities at Cuxhafen using seaplane tenders - although not an entire success, the raid was the first combined air and sea op, which was let down by technology rather than the concept. The aircraft used were Short Folder seaplanes, so called because, well, you work it out... Which was the same type used by Longmore to drop the torpedo, although they were used as bombers, not for carrying torpedoes.
Edmonds, who was the first person in history to sink a ship at sea with an air launched torpedo took part in the Cuxhafen raid and the captain of the tender HMS Ben-My-Chree, which carried the Short 184s in the Dardanelles, Cecil L'Estrange Malone was also at Cuxhafen.
In 1914 the first proposals for sinking the German High Seas Fleet at anchor in Wilhelmshafen were also written. Churchill (there he is again with extraordinary foresight) suggested removing the floats from a seaplane and fitting wheeled undercarriage to lighten the aircraft and enable them to carry a heavier torpedo to be carried aboard the ships, but his idea was shot down as being impracticable, although in 1915 and 1916, letters were written expressing the same idea and from these came the world's first aircraft carrier based warplane with a conventional undercarriage - odd, because the first aircraft carrier as we know it hadn't been built at that time, the Sopwith Torpedoplane, named the Cuckoo after the Armistice.
