Inert propellant pours into P120C

The first full-scale model of the P120C rocket motor that will propel Ariane 6 and Vega-C into orbit was cast and filled with inert propellant for intensive testing in Europe’s Spaceport in French Guiana in September 2017.

It is the largest single casting of a solid propellant motor ever achieved.

The photo was taken by a camera inside the casing.
