Design plan of a self-propelled rocket launcher on the chassis of the German HKL6p half-track transporter (ex. Sd.Kfz.251) dated 1 February 1949 (documentation Zb 170174P). The drawing in the source of information below shows a platform with an automobile cab (it is possible that it was intended to be an unarmored HKl 6p base, i.e. an artillery tractor Sd.Kfz.11 ?). In the rear of the platform a 32 multiple rocket launcher (4x8 rocket launcher bundle) is armed. The rockets fired were rotationally stabilized 130 mm calibre rockets. Behind the cabin was a magazine for 64 missiles. The project did not go beyond the plane of considerations. In 1950, a conceptual design for a self-propelled rocket launcher in a slightly different configuration was developed. Although the source of the information states that the platform was to be the HKl 6p, again it looks like an unarmored artillery tractor platform Sd.Kfz.11).
Development of the 130mm rocket continued further, resulting in mass production and introduction into armament as vz. 51.
