With HMS Severn being decommissioned after only 14 years of service and HMS Mersey and Clyde to follow in 2019 is there a future for these ships.

I think if the 3 early ships were upgraded in line with Clyde as far as radar and all 4 ships were given a weapons upgrade they could make a very good addition to any small or mid sized navy. But who if anyone is in the running for these ships?
