first I've heard of this.
The V-3 (Vergeltungswaffe 3) was a German World War II supergun working on the multi-charge principle whereby secondary propellant charges are fired to add velocity to a projectile. (multi-chambered)
The weapon was planned to be used to bombard London from two large bunkers in the Pas-de-Calais region of northern France, but they were rendered unusable by Allied bombing raids before completion. Two similar guns were used to bombard Luxembourg from December 1944 to February 1945.
The gun used multiple propellant charges placed along the barrel's length and timed to fire as soon as the projectile passed them in order to provide an additional boost. Solid-fuel rocket boosters were used instead of explosive charges because of their greater suitability and ease of use. These were arranged in symmetrical pairs along the length of the barrel, angled to project their thrust against the base of the projectile as it passed.

original prototype - long before the Nazi's refined it:

Trials were held at Misdroy from 20–24 May 1944 with ranges of up to 88 km (55 mi) being attained.
