Recasting the Harwich Force for modern warfare

What would a modern force performing the Harwich Force role look like?

Its functions would be distributed among submarines, aircraft and frigates rather than concentrated in one historical-style force.

No single modern formation directly replaces the Harwich Force because blockade, minefield and bombardment functions are now divided among different platforms. Submarines can contest access and attack shipping covertly. Aircraft add surveillance and rapid strike options. Type 23 and Type 26 frigates provide the surface-force element of the distributed mission.
