Somewhat interestingly in this regard, the German F125 frigates will have the planes of their MFR spread over both masts in order to both achieve full 360-degree coverage, and have redundancy in case of combat damage to one of the two masts.
The MFR will be optimized for short- to medium-range high-resolution surveillance, backed up by a 360-degree EO/IR system to reliably spot small-signature targets. All effectors will have their own EO/IR systems in addition to that, and not rely on the main radar systems.
