A "wonder weapon" would certainly be a "game changer"...but if we put WW2 into your context, every other day saw a "wonder weapon" when they issued the next mark of the Spitfire, or upgunned a B-25 or issued semi-automatic carbines instead of bolt-action rifles.I suppose it depends on whose definition of "wonder deapon" we are using. I have my own and everyone else doubtless has theirs. I think o the proverbial wonder weapon as a "game changer," and tehre most certaily WERE a few of those.

There is a considerable difference between a person's opinion and actual circumstances.
On the battle field, the introduction of the bow arrow was a "wonder weapon" because it all of a sudden allowed an army the ability to stand off and engage the enemy, however, as fearsome as it was, the longbow was only a technological leap foreward in the bow arrow's evolution. Just because the longbow gave the archers a tremendous advantage over the standard archers does not make it a "wonder weapon", it makes it a new threat to be countered. And the countermeasure for the longbow was...black powder, which was a "wonder weapon".
I don't believe that the Bf 109, Spitfire or T-34 were really game changers. Not in the sense that they really caused a break in the development of their type of weapon or a major change in tactics.
There weren't enough type XXI subs in action (if the war cruises of the German type XXI subs can even be called action) to change the "game" during WW II but they (or their level of performance) were certainly a "game changer" as they rendered not only hundreds of anti-sub vessels (some fairly new) obsolete but required new or different tactics and weapons to counter. Fortunately the west and Russia never came to direct blows in the late 40s or 50s but the threat of Soviet submarines of similar performance to the type XXI had NATO naval commanders going near crazy for quite a while. Subs that can go as fast or faster underwater than the AS ships that are supposed to 'catch' them certainly changed the game. Please remember that subs under water didn't have to slow down for sea conditions. Granted they could not do it for long but how long was needed to avoid a depth charge attack or even a hedgehog attack or to break contact with the sonar of the day? Much longer under water endurance and even the ability to 'cruise' at double the speed while snorkeling compared to earlier subs significantly altered the detection problem.
One can say that most all weapons are evolutionary but when you can take a line of weapons and break it into pre-XXX models and post-XXX models you can make a case for a game changing model. The Bf 109 and Spitfire didn't do that, many other countries were working on similar aircraft at the same time. There is no pre-109/Spit and post-109/Spit break in the development of fighter planes. A case might be made for the T-34 but it is on thin ice.
If it's new technology that hasn't been employed before, then the Me 262 qualifies, as do the XXI and XIII U-Boats. The Panzer was new technology. The B-29 was by virtue of being so much faster while carrying a LOT of load. The V-1 and V-2 qualify, too.
But this isn't something I want to drag on about. I can accept a definition and Graugeist's definition is OK. And he is right, a sharkmouth doesn't change a Bf 110 by much except to make it more easily seen in daylight.
Happy Holidays, Graugeist.
There were honestly several innovations that appeared in WWII that were "wonder weapons", the A-Bomb being one, of course.Point being, nothing was really a "wonder weapon" minus the A-Bomb.
As it stands, the Ta 152 was the final development of the Fw 190 due to the war ending. The potential of this aircraft had not been reached, but it was by no means revolutionary.
Actually the Long Bow was a 'game changer' even if not quite a "wonder weapon" in that it gave a 'peasant' army the chance to stand up in battle to 'traditional' forces ( the warrior class/nobility). It certainly did not guarantee success but it shifted the power (at least somewhat) away from the armored men at arms. It was replaced by black powder muskets because it took much less time to train a man to use a musket (a few weeks?) than to use a long bow ( a few, or not so few, years).
If we are talking about the English/Welsh armies of the 100 Years War just to be picky they werent a peasant army but were the sons of Land Owning farmers Artisan craftsmen and the Literate classes like Scribes, Lawyers and Businessmen. What today would be called the aspirational Middle class. Peasants had neither the time nor the money to go and spend time at the shooting butts to become a proficent Bowman they were too busy working. The Bowmen were volunteers mostly young in there late teens early twenties and went to war not particulary for any dynastic nationalistic reasons but for the pay and the chance of plunder.
Anyway your right the Welsh Longbow was a game changer but was no more than an evolution of a hunting bow. A Spitfire compared to a Sopwith Camel.
The advantage of a longbow was its range and rate of fire, the disadvantage was its inaccuracy and most of all the time taken to train. Longbow men took years to get the strength needed, archeologists can tell a longbowman because their skeletons are deformed.
