HMS Glatton was a breastwork monitor which served in the Victorian Royal Navy.
She was designed by Sir Edward Reed to a specific formula determined by the Board of Admiralty, and her purpose was never made wholly clear. Reed himself said "there is no vessel with the objects of which I am less well acquainted than the Glatton. She was designed strictly upon orders which I received and upon the object of which I was never informed". The Controller, the Fourth Sea Lord, stated that she was to be used for "the defence of our own harbours and roadsteads, and for attacking those of the enemy". In reality, her lack of freeboard would appear to have precluded any operations whatsoever except those in calm weather and smooth water. Her freeboard was no more than three feet amidships, and 4 feet 6 inches (1.37 m) at the bow. This must, however, be viewed in the context of U.S. monitors which served at sea and weathered heavy storms, such as the USS Weehawken. Glatton's raised amidships breastwork granted improved height above the waves for both her gun turret and hatches when compared to the U.S. model and it should be further noted that the Royal Navy successfully deployed the twin-turret breastwork monitors HMS Devastation and HMS Thunderer at sea with the fleet.
The ship was designed so that, although the main armament was mounted in a single turret, there would in theory be no point on the horizon to which at least one gun could not point, whatever the orientation of the ship. To achieve this the superstructure was made to be very narrow, so that at least one of the guns in the turret could fire on targets to the after aspect of the ship. It would appear that the blast effects on the superstructure from firing abaft the beam were not regarded as important.
According to Admiral George Alexander Ballard, who served on board as a junior officer, stops were fitted to prevent the firing of the main artillery much past the beam, but not until some years after the ship was launched.
Glatton was the best protected ship of her day, with some 35% of her displacement being devoted to armour.
Glatton, named for a village in Cambridgeshire,[1] was laid down at Chatham Dockyard on 10 August 1868, was launched on 8 March 1871 and completed on 24 February 1872.[2]
