The RAN submachine gun is a Belgian prototype submachine gun.
The RAN submachine gun was developed in 1950, and was one of a few contenders in a series of tests to find a new modern, and if possible, Belgian, design for a submachine gun. The RAN submachine gun lost out to the Vigneron submachine gun and it faded into history.
The RAN used blowback similar to most submachine guns of the time. It, interestingly, had a bipod.
