Of course, the round for extreme ranges will include additional propulsion and terminal guidance. A prototype munition exists but I do not know if it has been fired.
BTW, the first picture in Popular Mechanics is a display piece at Ft. Sill, OK. 1950’s era weapon.
Yeah, I didn’t read the article, actually.
;-)
Why bother using an artillery tube? Unless the exotic munition can be fired from an already-fielded cannon.
Anyways, it sounds like a science project t.
