I would think that perhaps they could...but on the other hand, they have never been billed as real ocean going vessels either. Therefore they would not normally have the need, and so perhaps the answer is just a simple no to UNREP.Partially OT, but can the type 056s conduct RAS with these fleet supply vessels? So I'm wondering how the type 056 would resupply at sea. I can see helo for goods but not fuel.
In addition, I have not seen any UNREP stations on them, but I haven't looked real hard either.
They can certainly perform VREP on them.
