In the annals of naval history, the Redoutable stands as a revolutionary vessel, marking the advent of steel as the principal building material for warships. Commissioned in 1878, this central battery and barbette ship ushered in a new era of maritime engineering, offering greater structural strength with a reduced weight compared to its iron counterparts.
The defining feature of the Redoutable was its ground-breaking use of steel, a material that redefined the parameters of naval architecture. The adoption of steel allowed for a formidable belt armour of 360 mm, complemented by a 380 mm backing, enhancing the ship's overall durability. The central battery boasted 240 mm plates, showcasing the versatility and strength that steel introduced to naval construction.
With an engine producing over 6000 horsepower, the Redoutable achieved a speed of 14.66 knots during its trial trip, setting a benchmark for naval propulsion in its time. The ship's operational range was equally impressive, covering 2,800 nautical miles at a speed of 10 knots. Torpedo defense netting underscored the commitment to defensive capabilities, and three masts with military tops carried Hotchkiss revolver machine guns for added security.
The Redoutable's offensive prowess lay in its weaponry, featuring seven breechloading
rifled guns of 270mm, each weighing 24 tons, and six breechloading rifled guns
of 140mm. Additionally, the ship was equipped with four torpedo discharge tubes, two on each side, further diversifying its strategic capabilities. As a key component of the French Mediterranean squadron, the Redoutable demonstrated its combat readiness and effectiveness.
In 1900, responding to the Boxer revolt in China, the Redoutable embarked on a significant journey to the far east, showcasing its enduring operational capabilities. The ship was present at the negotiation of the Boxer Protocol, a treaty signed on 7 September 1901 with China, solidifying its contribution to diplomatic endeavours. Transitioning to the Indochina naval division in 1905, the Redoutable continued its service until 1909 when it entered reserve status. Finally stricken on 9 March 1910 in Saigon, the ship's longevity was remarkable, owing in part to its partial steel hull. The dismantling process took place in situ from 1912 to 1913, concluding the chapter of the Redoutable's illustrious service to maritime history.
In retrospect, the Redoutable's pioneering use of steel not only propelled naval technology forward but also left an indelible mark on the evolution of warships, setting standards that influenced future designs and constructions.
