There was a certain 21 cm R Spr Gr 4401 rocket apparently to be produced in late 1944, 5000 pieces per month.
It consisted of a ballistic cap drawn from sheet metal, forged closure plate, machined (war)head, body of yet unspecified technology, cast fuel support ring, nozzles machined from seamless tubes, forged nozzle plate and cast rear body.
Production problems eventually lead to manufacturing the ballistic cap of three longitudinally welded segments.
It can be clearly seen, it was not the 21 cm Wgr 42 rocket, which did not have separate nozzles or a two piece body.
There were 21 cm rockets with separately mounted nozzles surrounded by a sleeve, which could be called the "rear body" - e.g. naval 21 cm RLg or some early 21 cm Fla-Rakete, but it is clearly none of these...
So what was the 21 cm R Spr Gr 4401? Some HE variant of the 21 cm RLg? Kriegsmarine did in fact use some 21 cm HE rockets for their 21 cm R Ag M 42 launchers, but I've never encountered any closer information about them. On the other hand, "21 cm R Spr Gr 4401" is clearly not a Kriegsmarine designation.
Any ideas, please?
Kind regards
