In German, the word "Senkrechtstarter" could be both a V/STOL aircraft and a vertical launcher.

DeepL and ChatGPT were able to translate correctly.

Thank you very much for the link to the instructions of the Tamiya kit! I have thought to buy it to build both a Mogami class with VLS and one without, but I am not sure if that is worth the effort (still very similar ships). Tamiya is a bit cheaper than Pit-Road.
