This one is confusing.
It is undoubtedly an anti aircraft weapon. But why? Could it be an amalgamation of test? (doubtful) or the rockets aren’t as advanced as they should be.
It is moveable, and the frame intricate. The removalable wheels, as they are shown, is no mean feet. These alone would require a fair amount of engineer work, and this could have been achieved without this work.
It is clearly designed for speedy erection by soldiers. The launcher is one piece when attached to the “turret” and there appears to be no small carefull work to fit it.
The range finder doesn’t appear to move, and wouldn’t be able to traverse up much. from it’s existing apetures.
At first, watching the video I wondered if was for bombardment of a naval/beach landing.
The rockets that explode, if that is what they were supposed to do in battle. The Germans already had shells that did this. And more shells could be fired from the existing guns in the same time as only 2 from this device.
The one thing that keeps coming up in my mind is that this is NOT a dedicated Anti-Aircraft weapon.
I am wondering if it is a replacement for large guns? It is far more moveable than a larger artillery piece, and could even be carried (i feel) short distances. You could put one of these on top of a bunker/building. The damage/effects of launch were important to someone, as they ahavebeen filmed.
The daylight shots don’t seem to explode, the night shots do.
