Sandown-class minehunters in Ukrainian service

How useful might Sandown-class minehunters be against submarines in Ukrainian service?

They are not oceanic ASW ships, but their minehunting sensors could be useful against submarines in shallow littoral waters.

Sandown-class sensors are optimized for finding mines rather than conducting blue-water submarine hunts. That specialization limits the class as a substitute for a purpose-built oceanic ASW platform. In littoral and shallow-water conditions, however, its sensor fit could still make it troublesome for submarines. Local water depth and mission environment can let a specialized minehunter contribute beyond its primary role.
