When the Royal Flying Corps was established it was intended to be a joint service. Owing to the rivalry between the British Army and Royal Navy, new terminology was thought necessary in order to avoid marking the Corps out as having a particularly Army or Navy ethos. Accordingly, the Corps was originally split into two wings: a Military Wing (i.e. an army wing) and a Naval Wing. By 1914, the Naval Wing had become the Royal Naval Air Service, having gained its independence from the Royal Flying Corps.
