Why was the Graf Zeppelin built & never finished?

    There was a fire with a big Zappelin (probably started by static electricity). Probably that caused the retiremenr of Hygrogen filled Zappelins worldwide.

    Unfortunate.. aircraft carriers would have turned the tide of war for Germany, I like to imagine the Graf Zeppelin being deployed in large numbers within the Atlantic ocean, retro-fitted to launch refined Ho-229 stealth fighters. However a lack of experienced personnel for service and training as well infrastructure for the construction of such a vessel was the nail in the coffin sadly. Germany was developing many technologies and principles which were too far ahead of it’s time, revolutionary, yes albeit greatly restrained by period technology.

      Yes, they just had a bad timing. They showed again and again, that they had the potential for greatness. Having a full size hangar ship, is a big deal even today. I think, that USA have 10, Russia 1, France 1, China 1, UK is having 2 on their way and thats it (a few countries have smaller size hangar ships).

        That is an interesting article, quite amusing to see that other naval powers utilize little more but “showboats” for aircraft carriers. Japan of course had many before the U.S. forced the Nippon into capitulation which resulted in the disassembly of their entire naval fleet including scuttling the impressive I-400 Super submarines which were in fact the technical precursor to American and Russian strategic submarines. Yes Aircraft carriers play a pivotal role in modern warfare as do submarines in which case Germany also was unable to upgrade it’s existing U-Boats, strategically speaking Adolf Hitler underestimated the role of Submarines in Warfare and very slowly became acclimated to the notion of such a vessel.

      “Adolf Hitler underestimated the role of Submarines in Warfare and very slowly became acclimated to the notion of such a vessel”

      I agree, or dont know any better. I think, that German U-Boats might have had to work parallel with the rest of the Kriegsmarine and Luftwaffe to have been succesfull with large scale 1945 technology.

      German Type XVII submarine
      https://en.wikipedia.org/wiki/German_Type_XVII_submarine

      “During World War II, the Kriegsmarine produced many different types of U-boats as technology evolved. Most notable is the Type VII, known as the “workhorse” of the fleet, which was by far the most-produced type, and the Type IX boats, which were larger versions of the VII designed for long-range patrols, some traveling as far as Japan and the east coast of the United States.
      With the increasing sophistication of Allied detection and subsequent losses, German designers began to fully realise the potential for a truly submerged boat. The Type XXI “Elektroboot” was designed to favor submerged performance, both for combat effectiveness and survival. It was the first true submersible. The Type XXI featured an evolutionary design that combined several different strands of the U-Boat development program, most notably from the Walter U-boats, the Type XVII, which featured an unsuccessful yet revolutionary hydrogen peroxide air-independent propellant system. These boats featured a streamlined hull design, which formed the basis of the later USS Nautilus nuclear submarine, and was adapted for use with more conventional propulsion systems. The larger hull design allowed for a greatly increased battery capacity, which enabled the XXI to cruise submerged for longer periods and reach unprecedented submerged speeds for the time.
      Throughout the war, an arms race evolved between the Allies and the Kriegsmarine, especially in detection and counterdetection. Sonar (ASDIC in Britain) allowed Allied warships to detect submerged U-boats (and vice versa) beyond visual range, but was not effective against a surfaced vessel; thus, early in the war, a U-boat at night or in bad weather was actually safer on the surface. Advancements in radar became particularly deadly for the U-boat crews, especially once aircraft-mounted units were developed. As a countermeasure, U-boats were fitted with radar warning receivers, to give them ample time to dive before the enemy closed in, as well as more anti aircraft guns. However, by early to mid-1943, the Allies switched to centimetric radar (unbeknownst to Germany), which rendered the radar detectors ineffective. U-boat radar systems were also developed, but many captains chose not to use them for fear of broadcasting their position to enemy patrols and lack of sufficient electronic countermeasures.
      Early on, the Germans experimented with the idea of the Schnorchel (snorkel) from captured Dutch submarines, but saw no need for them until rather late in the war. The Schnorchel was a retractable pipe that supplied air to the diesel engines while submerged at periscope depth, allowing the boats to cruise and recharge their batteries while maintaining a degree of stealth. It was far from a perfect solution, however. Problems occurred with the device’s valve sticking shut or closing as it dunked in rough weather; since the system used the entire pressure hull as a buffer, the diesels would instantaneously suck huge volumes of air from the boat’s compartments, and the crew often suffered painful ear injuries. Waste disposal was a problem when the U-boats spent extended periods without surfacing, as it is today. Speed was limited to 8 knots (15 km/h), lest the device snap from stress. The Schnorchel also had the effect of making the boat essentially noisy and deaf in sonar terms. Finally, Allied radar eventually became sufficiently advanced that the Schnorchel mast could be detected beyond visual range.
      Several other pioneering innovations included acoustic- and electro-absorbent coatings to make them less of an ASDIC or RADAR target. The Germans also developed active countermeasures such as facilities to release artificial chemical bubble-making decoys, known as Bold, after the mythical kobold.”

        Ah yes, the “German submarine U-480 (stealth submarine)” The Japanese I-400 was outfitted with the very same rubber composite tiles which rendered their vessels undetected via American sonar systems. It fits considering all of their technology was originally German. Germany also suffered from the consequences of refueling it’s U-Boats resorting to using remote Arctic black-sites and specialized tanker subs dubbed “Milk Cows” which were virtually defenseless ticking time bombs. Again we have the limitations of period technology exposing the vulnerability of early Submarines which would have to resurface to expend waste, re-fuel, obtain air for breathing and diesel engines hence could not sufficiently deploy for long periods of time unlike modern subs.

        Of which we witness the marvels of innovation, one would be callous/ignorant to not admit cleaning water/air while creating electricity as a electro-chemical byproduct via oceanic salt water and hydrogen fuel cells to be astounding.

        I am not even going to bother mentioning Nuclear powered submarines as the rest of the world aside from the U.S. and Russia have avoided such a venture.

      I agree, that was new to me!

      Interesting, links. Thanks.
      I have made a post about “Kockums vs ThyssenKrupp – The submarine conflict” , you might find it amusing.

      German Type XIV submarine (a dangerous job)

      “In 1942, the milk cows allowed the smaller Type VIIC boats to raid the American coast during the “Second Happy Time” of the Battle of the Atlantic. The milk cows were priority targets for Allied forces, as sinking one milk cow would effectively curtail the operations of several regular U-Boats and force them to return home for supplies. Ultra intercepts provided information concerning sailing and routing, and this, coupled with improved Allied radar and air coverage in the North Atlantic, eliminated most of them during 1943. By the end of the war all ten had been sunk. Milk cow duty was especially hazardous; 289 sailors were killed out of an estimated complement of 530–576 men.”
