Time notes
- 0:45Why HMS Shannon failed as an armoured cruiserChapter
The Royal Navy's first armoured cruiser combined ambitious mid-Victorian ideas in a deeply unsuccessful design.
- 3:23An armoured citadel that left the guns exposedNotable Point
Shannon's belt stayed above water, but its unusual placement protected none of her gun positions.
- 4:42Heavy guns without a Pacific ammunition supplyNotable Point
The Pacific Station held no replacement ten-inch ammunition for Shannon, preventing routine practice with her largest guns after deployment.
- 4:42The ramming charge and electric broadside conceptChapter
Shannon was meant to charge bow-on behind ten-inch guns, ram her opponent, and electrically fire a nine-inch broadside while passing.
- 8:42One cruiser asked to counter several fleetsNotable Point
Shannon combined responses to Russian and French armoured ships with commerce-raiding and commerce-protection duties.
- 9:21Sail area that threatened stabilityChapter
A full ship rig insisted upon by Captain Arthur Hood proved excessive and was reduced to a barque rig after service trials.
- 10:19Slow machinery and the last lifting screwChapter
Shannon missed her thirteen-knot target, doubled her coal capacity, and retained a lifting propeller to improve performance under sail.
- 11:41Muzzle-loaders, partial rearmament, and torpedoesChapter
Shannon began with two ten-inch and seven nine-inch muzzle-loaders before receiving an incomplete breech-loader refit and four torpedo tubes.
- 12:35Belt, deck, teak, and coal protectionChapter
Shannon concentrated iron and teak around a forward citadel, with a submerged armoured deck and coal stores intended to limit bow flooding.
- 15:24A Victorian cruiser designed to refight TrafalgarNotable Point
Shannon's bow-heavy protection appears to have been an iron-hulled attempt to survive the head-on line-breaking tactics associated with Trafalgar.
- 17:52Too slow for the overseas cruiser roleNotable Point
Although intended as a foreign-station ironclad and cruiser, Shannon's roughly twelve-knot maximum undermined her ability to perform cruiser missions.
- 18:52Delayed commissioning and brief Pacific serviceChapter
Weight and machinery defects delayed Shannon, interrupted her China Station dispatch, and limited her eventual Pacific deployment to 1879-1881.
- 20:54From cruiser to Warrior's tenderChapter
After refit Shannon became tender to the older HMS Warrior and ranked near the bottom of the reserve mobilization during the Panjdeh crisis.
- 23:06An expensive failure the Royal Navy could learn fromChapter
Shannon cost roughly £304,000-£306,000 with armament, but Britain's industrial capacity allowed later cruiser designs to improve beyond this costly experiment.
- 26:02The institutional problem of a failed warshipNotable Point
The closing prompt asks how an 1880s naval power should acknowledge, employ, or quietly dispose of a warship that has proved a complete failure.
