What if Germany developed the V-3 cannon much earlier?

Would the posession of the the V-3 cannon in the war's earlier phases turn the war in Germany's favor? I'm thinking of positioning the V-3 cannons across the entire Atlantic Wall and then continously barrage southern Britain, London included, until the UK surrenders; or using them offensively and defensively on the Eastern front.

 

Nope, the multi-chamber "Centipede" was too difficult to get to work, even with today's computer control getting those danged ideas to function is cost prohibitive.

A non-starter as an concept, mcuh like the V-1 and V-2 ideas, too little return of impact on target for cost of investment in the system. The other problem with those darned things is they have to be established in place, a couple of shots toward the Isles, and they become targets that are frozen in place and cannot be moved.

 

They built quite a few of these in several sites but they were prohibitively expensive and costly in terms of material and diversion of engineers and scientists from more important projects.
The few used during December 1944 to January 1945 against Luxenbourg did nothing to influence the war (180lb of propellant to send a 210lb projectile with just 20lb of explosive nearly 30 miles). They failed to hit even a city accurately or consistently and were fired from a fixed position so could not be re-aimed without being dismantled and re-assembled in a new position. The only adjustment they had was varying the amount of propellent to adjust the distance or try to compensate for windage etc.

 

Firing "small" projectiles of that order compared to the one ton warheads of the V-2, it would have been almost impossible evaluate damage to London and its environs by the LW. The V-3 would, with its clumsy or non-existent aiming system, be entirely vulnerable to the disinformation techniques the British used to lure the Germans' targeting of the V-2 away from the heart of the city.

Also, lets' face it - none of the LW's blitz attempts on the capital or its surroundings did much to reduce its contribution to the war effort; there was a huge number of war factories in and around London, as well as it's administrative role - every day, throughout the war, the Southern Railway moved two million workers in and back out of the capital A few dozen projectiles of 210lbs with a 20lb burster charge....probably less than an early-war SC250 bomb!!!...isn't going to do anything towards destroying the capital if the Luftwaffe failed Meanwhile, by 1943-44, the many and various government ministries an departments all had their emergency plans to relocate out of the capital in the event of invasion still in place...
