well i did some research the other day and found out that maritime patrol aircraft are usually large and
slow machine capable of flying continuously for hours and most of this maritime aircraft are running on turboprop engines. The OV 10 fit that category, it may not compete with other crafts in terms of flight time but duol ra man pud ang spratly sa Palawan.
it is really not that bad considering pud mas older ang P-3 Orion (almost 50 years) and still active today and in fact the Chinese Navy are buying P-3s by 2012 for maritime duties.
