Duquesne class Cruisers

France (1925)

Duquesne, Tourville

The Duquesne and Tourville were the first heavy cruisers from the Washington Treaty in France, and the first since 1906. Preceded in 1923-24 by the three Primauguets (light cruisers), these buildings were wider, had the artillery classic ” washington “of 8 pieces of 203 mm, all with a tonnage of less than 10 000 tons. In rivalry with the Italian Navy, the emphasis was on speed. From the start a speed of 32-33 knots was required. At the tests, it was possible to reach 34 knots, but the “normal” maximum speed was 33.5 knots. With a length of 191 meters, a length / width ratio of 1:10, it was possible to meet the standard 10,000 tonnes only at the cost of a very light construction, so much so that their action in the North Atlantic was not time not even considered …

The lack of armor screaming indicated that in case of a fight against other buildings of the same class, they would have cashed the shots without being able to support them. But their philosophy was primarily based on the tactical use of speed, as well as for battle cruisers. Their Creusot pieces just left the arsenals were 31,000 meters, which at the time put them “out of reach” of most cruisers. They fired up to four salutes a minute, which was also very honorable.

Be that as it may, they hardly had the opportunity to prove their military value. Indeed in June 1939, after having served with escorts in Mediterranean, the two ships were immobilized … (historical missing !!)
