Not sure why an MPA also needs to be AT/AAR.
e.g. expand range for SAR operations, move fuel between MPA, support e.g. strike aircraft.
It's a big machine with big fuel tanks. The days of a tanker is a tanker, a transport a transport and a MPA a MPA are probably gone.
If the dutch MPA's would have had the above capabilities, being smalller /cheaper, having operational flexibility instead of stubborn sticking to cold war ASW, the squadron probably would have still existed.
