On 23 December 1918 the Naval Ordnance Store Department was renamed the Armament Supply Department and its depots were likewise renamed Royal Naval Armament Depots (RNAD) in 1920. The change of nomenclature recognised the inclusion of torpedoes and naval mines (which had been managed separately during the war) alongside ordnance as part of the new department's responsibilities.
The Royal Standard is also flown from aircraft and water vessels, including HMY Britannia and MV Spirit of Chartwell during the Thames Diamond Jubilee Pageant. When the monarch is aboard a British naval ship, the flag is flown from the main mast of the ship and is lowered upon his/her departure.
