The V4 or \"Rheinbote\" missile is undoubtedly the least known weapon that had to serve as a weapon of retaliation. In the end it was only used against Antwerp, for strategic reasons just like the more famous V1 and V2 at that time.<\/h3>\n

The principle of the multi-stage rocket has existed in the Far East since the Middle Ages and was already researched in the years before WW2.<\/b><\/p>

To increase the range of artillery without the mobility problems of increasingly heavier guns, the Rheinmetall-Borsig company from 1943 developed a design with 4 separate drives or \"stages\". The great distance that could be bridged and the potential to deploy them in large numbers meant that this weapon was also considered a useful tool for those planning retaliation against England. Despite the plans for the production of thousands of units, 220 were eventually produced.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

To deliver a projectile of 40 kg (of which about 30 kg were explosives) over the desired 160 km, a combination of 4 missiles more than 11 m long was used.\nThe first stage with 6 exhausts fired for only 1 second with the rocket rocketing into the air at 20m per second. Despite the short time for its decoupling, this stage already fell about 3 km from the launch point. Subsequent stages fired at 2, 12 (duration 5 seconds), and 22 seconds (3 seconds). The last stage remained attached to the charge after firing. With a top speed of almost 6000 km\/h and an altitude of about 80 km, the right parabola could hit a target at a great distance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Despite the low impact as a weapon and the high cost of materials with each shot, the order came to prepare for operational deployment.<\/b><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tIn December 1944, Artillerie-Abteilung 709 arrived in Nunspeet (NL) and fired the first \u201cRheinboten\u201d at Antwerp, 165 km away. This first deployment on 24.12.1944 started promptly at 12 noon and consisted of a pre-salvo of 4 missiles, after which the planned 6 similar salvos could be fired within the hour.\nAlthough the launches succeeded, it was far from certain that the correct distance had been covered, verifying this was almost impossible.\nThe preparation of a correct firing table, which indicated the correct degree of inclination for a certain distance, was not yet completed at this first deployment, so that a theoretical calculation had to be used. Locating the relatively small impact crater of about a meter after each shot to determine its accuracy was a challenge in tests carried out in area's under German control and virtually impossible in enemy territory.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

After a few more launches towards Antwerp from near Nunspeet in January 1945, the entire project was halted a few weeks later.<\/b>
In the meantime, additional tests had shown that all previous shots landed well beyond the target. The 64 degrees that was calculated and used as a setting did not give the projectiles the expected range of 165 km, but an average of about 230 km.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

On February 6, 1945 it was decided to stop the Rheinbote project which would be the fastest missile in WW2.<\/b><\/p>\n

In the press the name V4 was regularly used incorrectly for the Re4 \u201cReichenberg\u201d from 1945, which causes confusion to this day.
\nAfter the V3 (multi-stage gun), the multi-stage missile was the \u201cVengeance weapon 4\u201d, the Re4 evolved from a V1 but was not one itself.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
