I am sure that many of the existing metal jerry cans might still be in use 50 years in the future from now.
However the cancellation notice for the military standard that was posted above mandated that all military procurement after June 1994 must be done only with plastic cans.
I have been using a couple of traditional jerry cans for several decades, but I have seen the new military plastic cans only in photos. They must be obviously much lighter, but I have no idea if besides this advantage they have disadvantages when compared with the metal cans that they have replaced.
