    Hard to say given units requested for ships and ribs.Most likely the transponders are for ribs say 6 ships and one for a rib on each and poss one transponder for diving unit operating from shore.Again it may be the P50s already have the same compatible units.
    I would have thought a unit also needed for NS ops centre and one for training.
    Most likely ship units to be fitted in ops control as the helmsman will have enough VDUs wrecking his/her night vision and data repeated onto existing radar/gps display.
