What were the 'Bearns' of the other Major Navies? RM, IJN, USN, RN & Kreigsmarine

Bearn's three raised lifts disrupted airflow and presented rigid obstacles on a working carrier's flight deck.

Changing Bearn from all-turbine machinery to a mixed installation worked against a hull already designed for turbines.

Bearn defines a test of well-intended features that obstruct a ship's mission, with unused treaty tonnage distinguishing its compromises from those of French treaty cruisers.

Dupuy de Lome shows how packing new technology into an armoured cruiser could obstruct the presence and diplomatic work expected of the type.

Mogador's 39-knot and 35-knot torpedo settings constrained manoeuvres by a destroyer capable of nearly 40 knots.

Turbine's speed and torpedoes suited offensive attacks, while its limited gunpower weakened it as a general-purpose destroyer.

Its destroyers limited the fleet. Many were optimized for offensive torpedo attacks and lacked the gunpower and versatility needed to screen and defend a force.

Zara's attempt to improve on the Trento class traded away shafts, internal subdivision, and proposed armour while still exceeding treaty displacement.

Bow aircraft arrangements obstructed gun use during recovery and put aviation fuel in a lightly protected part of the early Condottieri cruisers.

Early Condottieri cruisers had only a brief maximum-range advantage over Le Fantasque in a head-on approach, followed by an expensive fight for a larger target.

Fubuki's formidable guns and torpedoes are weighed against topweight, sea-keeping, and the unused freedom available before treaty limits tightened.

A hypothetical larger Fubuki combines a fourth gun turret with heavy torpedo armament and raises the possibility of more generous destroyer-leader allowances.

Mogami was prepared to exchange six-inch for eight-inch guns without making the rest of the cruiser equally ready for its heavier intended role.

Ryujo shows how doubling aircraft capacity on a sub-10,000-ton carrier created topweight and sea-handling problems that repeated reconstruction could not erase.

A 24-aircraft Ryujo provides a counterfactual case for light carriers that could cover convoy and some fleet duties while reserving tonnage for strike carriers.

Pensacola's narrow scouting hull and elevated triple turrets produced rolling that directly interfered with its intended work in heavy seas.

Ranger achieved a large nominal air group on modest displacement, but its light flight deck, omitted torpedo facilities, and limited growth margin narrowed its wartime use.

A rejected major reconstruction and the smaller May 1944 refit explain Ranger's useful employment as a night-fighter training carrier.

Pre-war armament cuts and wartime additions expose the difficulty of fitting greater capability into the Sims class's lighter hull.

Texas and Maine appear as flawed early designs whose shortcomings were offset by their place in the US Navy's institutional and shipbuilding growth.

Dido's dense anti-aircraft battery made it a capable specialist while topweight and crowding reduced its broader cruiser qualities.

Steam propulsion imposed a heavy machinery installation and two funnels on the K-class cruising submarines despite the availability of diesels.

The York class cut one turret from the County pattern, leaving six eight-inch guns at a serious volume-of-fire disadvantage against modern light cruisers.

Twin turrets gave Arethusa less firepower than a triple-turret alternative but prolonged ammunition supply and freed space for distant operations.

Reducing a planned twelve-gun battery to ten left King George V dependent on complex quadruple turrets, with Prince of Wales's Denmark Strait difficulties as the example.

The preference for fourteen-inch guns sought international restraint while Japan left the treaty system and objections arose inside the Admiralty.

Bismarck remains a potent battleship despite a harsh efficiency judgment, while the hypothetical Littorio comparison depends on ammunition quality.

Königsberg's stern gun arrangement and minelaying system interfered with one another while sensitive loading made damage stability a serious concern.

Uncertain design intentions keep Type 1934 outside the chosen Bearn example, while Graf Zeppelin's gun-requirement anecdote illustrates the bureaucratic criticism.

Deutschland's eleven-inch guns came with light protection and about 28 knots, leaving it vulnerable to stronger ships capable of catching it.

Long endurance helped commerce raiding, but prize-rule stops and lightly built merchant targets gave little reason for Deutschland's eleven-inch guns.

Deutschland's heavy guns attracted capital-ship hunters, while Germany lacked the fleet needed to exploit the diversion of those enemy forces.

Six eleven-inch guns compare poorly with Gangut's twelve twelve-inch guns, while confined Baltic waters limit the value of Deutschland's speed advantage.

An alternative eight-inch cruiser and Admiral Graf Spee's fate at the River Plate sharpen the criticism of Deutschland's conflicting global and Baltic roles.
