Footage from the presentation during the AUSA 2018 conference in the USA.
The length of the barrel 58 calibers (was 39).
Test frames at the beginning of the report

Says longer barrel obviously you can see it in the pictures. Also includes auto-loader and reduce the crew to 3. Think its about time since the cancellation of the Crusader artillery program IMO.

For a minute I thought it was a modern day TD.
But well, it does look good for an arty and the longer the barrel the more precise the strikes would be...
