Abstract
A recoilless projectile launcher system has a projectile residing in a launch tube with a propellant charge coupled to the aft end of the projectile. A first tube is slidingly fitted in the launch tube, is coupled to the aft end of the projectile, and encases the propellant charge. The first tube has a first portion extending from the propellant charge and a second portion extending from the first portion towards the breech end. The first portion has a constant inside diameter while the second portion has a reduced inside diameter relative to the constant inside diameter of the first portion. A piston, slidingly fitted in the first portion of the first tube, is positioned adjacent the propellant charge. A second tube is coupled to the piston and extends towards the launch tube's breech end. The second tube has a constant inside diameter and a constant outside diameter with the constant outside diameter forming a sliding fit with the second portion of the first tube. A dispersible countermass resides in the second tube and is dimensionally stable independent of the second tube.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
