Austria-Hungary, AFAIK, doesn't exist in this timeline - it'd be the HRE.
So I take it you don't know about the German submarine-barge designs to load a fully-fueld V2 into a floating missile silo and then tow it to somewhere off the atlantic seaboard?The Submarine Dreadnoughts
As the second world war drew to a close, the peoples of Europe, pled with one voice to not let such slaughter occur again. Their generals and admirals understood, and vowed that next time, they would not be so unprepared. Their leaders and politicians, understood, and upon seeing the admiral's budget, vowed to give peace a chance. The resulting patchwork of treaties failed to the prevent the world sleepwalking into another war, even more destructive than the last, but the complex game of political restrictions, technical innovation and outright fraud created some of the strongest design pressures any navy ever faced. Great innovations were made to sneak devastating weapons of war under the treaties, and even greater mistakes of engineering were imagined that otherwise would have never seen the light of dawn.
Many would argue that the Submarine Dreadnoughts should fall in the latter category. The name is not an official military designation, nor was it ever used by any military in the war, but is instead taken from the speculative fiction novel of the same title in which they had their greatest successes, and which popularized them among the general population. Their origin finds itself in the Vienna Naval Treaty of 1921, and the exceptions the Holy Roman Empire secured therein. Among several more useful clauses restricting battleship and cruiser construction, the HRE expended significant political capital to secure an exception safeguarding the future of merchant submarines. Those storied vessels had run the british blockade, and were widely believed by both public and military establishment at the time to have been essential to keeping the empire in the war. As such, the final draft authorized all nations to maintain a fleet of large, largely demilitarized submarine cargo vessels. As civilian vessels, these vessels would not contribute to the arms race, and could greatly reduce civilian suffering.
U-220 Class (Austria Hungary)
A class of 3 vessels (SM U-220, SM U-221, SM U-222) of large cargo vessels, intended to maintain trade and communications with the overseas colonies and the HRE's Japanese allies during a second British blockade. Although a serviceable design in this original function, by the time of the war naval thinking had long shifted from a policy of enduring a second blockade, to one that sought to contest the seas and break through. Although this would ultimately proof less than successful, it did mean that most of the intended U-220 class were never laid down.
While SM U-220 and SM-U222 would perform their intended role through the war, SM-U221 would see new purpose under project Wotan. This attempt at militarization of the massive submarine saw the installation of a capital ship grade cannon on the bow, as well as the installation of torpedo tubes and mine laying equipment. While the latter was a fairly standard (if heavy) armament for a submarine, the forward gun was far heavier and far greater in caliber than any yet mounted on a submarine. Intended to destroy an enemy combat craft with a single surprise shot, the battleship cannon was upscaled several times during the vehicles troubled development. The final configuration envisioned a 300 mm canon capable of launching a nuclear shell.
Development was fraught. The U-220 class had never been designed for quick diving or underwater speed, and the addition of a massive cannon seriously worsened it's mediocre sea going capability, both above and below the water. Firing procedures on the weapon were incredibly troublesome, with loading the gun requiring the crew to first assemble a portable crane capable of lifting the warhead. As performing this action in combat was obviously infeasible, it was expected that the crew would load the warhead before approaching the convoy, with a watertight plug protecting the canon and extended battery allowing the shell to remain active and armed for up to two days. Further complicating this combat operation was a strict limitation on tolerable recoil, causing significant range limitations. While it was expected that the submarine could easily sneak within effective range, there was a considerable overlap between the warhead's area of effect and the gun's maximum range. Firing procedures optimistically called for the crew to take cover behind the ship's sail or in the water, while the gun itself was painted in heat resistant ablative paint.
Ultimately, SM-U221 would never see combat, as all nuclear warheads were instead deployed via bombers. The SM U-221 is sometimes known as the last HRE force, as it remained at sea for nearly a year after revolutionaries overthrew the HRE and captures it's home port. This historical myth, though popular, ignores the extensive communication between the SM U-221 and negotiating governmental remnants in Europe, which show that rather than an idealistic remnants, SM U-221 was part of a hight stakes political game where it's nuclear potential was used by various conservative aligned political groups to secure additional safeguards and concessions from more radical revolutionary members. Ultimately, SM U-221 would return to port without warhead or cannon, having disposed of them at sea, providing fertile soil for a litany of conspiracy theories, from those alleging the voyages were searching for or found the lost city of Atlantis, to those alleging the existence of an undersea nuclear arms depot, to those claiming that SM-U221 never had any nukes at all.
I-400N Class (Japan)
Although build under the Merchant Submarine exception, the I-400 was designed from the start as a military vessel. Taking advantage of the fact that regulations had never expected anyone to launch a plane from a submarine, the I-400 dove straight into the resulting legal loophole. In the process, Japanese naval engineers quickly discovered just why this had never been done.
The I-400N (and it's smaller predecessors) were among the largest submarines ever build, yet could only carry a scant handful of planes. With no ability to install either a runway or steam catapult, total bombload was incredibly limited, and the massive size of the resulting submarine made diving operations incredibly sluggish. The I-400M was categorically incapable of executing an emergency dive. The required diving angle would mean the tip of the bow would exceed the vehicles depth tolerance, while the aft was still lifted above the water.
Although the project languished in obscurity for a few years, the introduction of nuclear arms caused a brief resurgence in interest. Armed with a single nuclear warhead, and reliant on a solid rocket booster to get in the air, the I400's dive bomber finally achieved the firepower to do real damage. The cost was considerable. With far greater weight, reduced fuel capacity and still sluggish speed, the chances for the plane to evade air defenses were negligible. Although never enacted, final procedures for the deployement of nuclear warheads on the I-400N called for suicide missions.
Tortoise class (USA)
The only class to be build in full, and never militarized, the Tortoise class both faithfully represented the intended purpose of the submarine merchant exception, and also suffers from a complete lack of tactical or strategic purpose. Build entirely to keep up with similar developments in the HRE and Japan, and funded largely as a depression era jobs program, the Tortoise class found itself quickly and entirely without purpose.
Some of the vessels would be utilized to supply the United Kingdom, but the vessels slow speed, high cost and vulnerability to aerial attack near the british coast rendered it generally inferior to the cheaper Liberty ships. Attempt to utilize the vessels in the Pacific similarly failed, with local commanders preferring more combat submarines over trying to keep the sluggish cargo cruisers supplied and operational. Ultimately, the Tortoise class was reassigned to the similarly defunct US Army Airforce airship division, which converted some of the hulks into Barrack ships. Perennially unpopular with the anyone who had to sleep aboard, the practice was abandoned as soon as possible, and most of the ships spend the rest of the war in obscurity.
The only exception is Hull 17, which although never finished gained a great amount of notoriety for its use as a floating prison for dissidents in the early of the revolution, and it's dramatic capture.
I know of it. Just didn't feel like doing that particular bit of sillyness.So I take it you don't know about the German submarine-barge designs to load a fully-fueld V2 into a floating missile silo and then tow it to somewhere off the atlantic seaboard?
Check it out.
Bleh, I thought I fixed all of those.Austria-Hungary, AFAIK, doesn't exist in this timeline - it'd be the HRE.
