Flotilla Leaders were generally named after famed historical (and generally, naval) characters and vessels building for other countries that had been commandeered for the Royal Navy were not allocated into the letter system (e.g. ex-Turkish ships received "T" names and ex-Greek ships "M" names with a Greek mythology theme).
