For a navy that once ruled the sea in the service of one of the mightiest empires ever created, Royal Navy is today a mere shadow of its former glory. Once the greatest navy in history, it only ranks 5th in 2017 rankings of the strongest navies in the world. Royal Navy’s only aircraft carrier, HMS Queen Elisabeth, will be commissioned in May 2017, while her sister ship HMS Prince of Wales, currently under construction, will enter the active service in 2020. Until then, the only power projection capabilities Royal Navy possesses are summed up in HMS Ocean.
