510 Offshore Patrol Vessel
From WikiAlpha
The 510 OPV is a class of patrol vessels offered by the Abu Dhabi Ship Building consortium. The vessel's hulls will be 51 meters long. They are designed to operate in rough seas.
The class was first introduced at the Indo Defence Expo & Forum 2022 in Jakarta.
The vessels will carry at least two fast interception daughter craft, and can be configured to have a helipad large enough to launch and retrieve small unarmed surviellance drones.
