HMS Glatton (1871)

HMS Glatton was a breastwork monitor which served in the Victorian Royal Navy.

Design
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 ft at the bow.

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 G.A. 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.

Service history
She was commissioned in 1872 immediately into the Dockyard reserve, as tender to the gunnery school Excellent. She was a part of the 1878 Particular Service Squadron. In July of that year she was fired upon during live firing trials. In 1881 she was fitted to discharge 14 in torpedoes. At the same time three QF 6 pounder Hotchkiss and 4 machine guns were added to her armament. In 1887 she was specially commissioned for the manoeuvres, and with HMS Prince Albert (1864) allocated to the defence of the Thames estuary. This is her only recorded operational sea-time. Thereafter she passed through second class reserve, fleet reserve and dockyard reserve status, until she was sold in 1903.
