“The construction of the ’90-meter OPV’ and ‘OPV’ is a form of promoting the national defense industry to increase the capacity and expertise in the construction of warships in the future, as well as encourage the recovery of the national economy.”Head of the Defense Facilities Agency (Kabaranahan), Kemhan Marsda TNI Yusuf Jauhari.
This still needs to be confirmed formally, but according to our information, both OPVs are set to have a length of 90 meters, a width of 13.5 meters and will be powered by four 7,280 KW diesel engines. Both should be able to reach a maximum speed of 28 knots. However one is expected to feature equipment to accommodate a helicopter (helideck and hangar) while the other OPV will lack such facilities.
