The French submarine Monge
“One of 18 Pluviôse-class submarines built for the French Navy (Marine Nationale) in the first decade in the 20th century.(…) The first six boats completed were armed with a single 450-millimeter (17.7 in) internal bow torpedo tube, but this was deleted from the rest of the submarines after an accident with their sister Fresnel in 1909. All of the boats were fitted with six 450 mm external torpedo launchers; the pair firing forward were fixed outwards at an angle of seven degrees and the rear pair had an angle of five degrees. (…) Monge, named after the 18th-century mathematician and Minister of Marine Gaspard Monge, was ordered on 24 August 1905 from the Arsenal de Toulon. (…) At the outbreak of the First World War Monge was part of the French Mediterranean Fleet and sailed with that force to the Adriatic tasked with bringing the Austro-Hungarian Fleet to battle or blockading it in its home ports.”

“D” Class Submarine, UK 1908
“The Royal Navy’s eight ‘D’ Class Submarines entered service between 1908 and 1911. The Royal Navy considered these to be ‘patrol’ (as opposed to coastal or fleet) submarines. They were significantly larger than the preceding classes and, with twice the endurance offered the British their first plausible ocean-going submarines. The Grand Fleet Battle Orders specified that the top speed on the surface was 13 knots, but that a more realistic ‘sea-going speed’ was 11 knots. The two forward tubes were mounted one atop the other, which allowed a sleeker hullform but which complicated the loading arrangements in the confined space. A single cap for the forward tubes rotated 90° in ‘roll’ to uncover both tubes at once. In effect, this piece was the prow of the submarine.”
The Dreadnought Project
Pochtovyy, Russia 1905
“Drzewiecki design, construction funded by public subscription between workers of Russian mail service, so the submarine was named Pochtovyy [i.e. Mail]. The chief aim of the design was to provide a submarine with a single diesel propulsion when surfaced and submerged. Because of the lack of a suitable diesel engine in 1905 gasoline ones were fitted instead. These were supplied with oxygen from 45 air cylinders (10m3 of air under 500kgf/cm2 was carried) when submerged. Exhaust gases were ejected overboard by compressor jointed to a perforated pipe under the keel. With only 1 engine running she was able to cover 28 miles when submerged and 350 miles on two another engines when on the surface. The whole system proved reliable enough but further refinement was abandoned because of steam collecting inside the hull when the boat was submerged and the bubble wake on the surface.”
