HMS Victory was a First Rate Ship of the Line. This means that she had to have at least 100 guns-in fact at the time of Trafalgar she had 104.
Ships like HMS Victory did not have 'cannons' at sea these large weapons are always known as guns. Sailors also had small arms such as rifles and muskets.
Her Majesty’s Ship Victory is the only surviving naval warship that represents the skill of naval dockyard shipwrights, ship designers and the industrial ability of Britain during the mid 18th century.
More than this the Victory is equally a classic example of warship construction techniques used by all maritime powers of that period including Denmark, France, Holland and Spain, also the lesser naval powers of Russia, Naples, Sweden and Turkey.
Besides her historic role serving as Admiral Lord Nelson’s flagship at the battle of Trafalgar, the Victory stands in the line of technical advances made between the 16th century Tudor warship Mary Rose, the Victorian built iron warship Warrior of the mid 19th century and the steel built monitor M33 of the early 20 century.
Simply just a manoeuvrable floating weapons platform, the Victory is likewise historically comparable with the modern naval warships of the 21st century.
As Victory has been commissioned for over 200 years she has had many Commanding Officers and Flag Officers.
All ships have Commanding Officers, they are the captains and are responsible for that particular ship and its crew. Flag Officers are Admirals and are in charge of whole fleets of ships. They have a Flagship from where they command their fleet. HMS Victory is the flagship of the Second Sea Lord.
