French Rocket identification help

[Fr05ty]

I'm trying to find out any information on the 5" rocket and the 180mm rocket mentioned here. The picture is for the Matra Type 13 rocket launcher platform for aircraft. The full document is here: https://www.3af.fr/sites/default/files/comaero_08.tugaye_armements.pdf (the image is on page 31). From what I can see, the 5" rocket has a 60kg mass and the 180mm rocket is mentioned as being "180 CEP Type 301" rocket with a mass of 80kg. Any information on this would be very appreciated!

CEP stands for CHIMIE ET PROPULSION (CHEMISTRY AND PROPULSION).
According to "L’industrie aéronautique et spatiale française 1907-1982", Vol.3
«This 180 mm rocket was made of a 127 mm diameter motor with a cruciform grain that was directly inspired by the 5 inch American rocket. The warhead, on the other hand, had a mass of 50 kg and a diameter of 180 mm. The explosive mass/metal mass ratio was approximately 1. An order for 10,000 rockets planned before the Algerian War was not executed. »
