A recent Naval News report of the choice of an Electronic Warfare System for new Indonesian OPVs, with the illustration above, prompted me to find out more about these unusually fast and apparently well armed OPVs being built for the Indonesian Navy.
Steel was cut for the first of class on 26 August, 2021. (This report may be a bit confusing in that steel was cut for two OPVs of two different classes.) This report indicates these ships will be powered by four Diesel engines developing 7,280 kW (29,120KW total). That would equate to about 39,000 HP which sounds about right for 28 knots. It is not clear from any of the illustrations where the air intakes and engine exhausts are.
Defense Indonesia provides some specifications:
- Length: 90 meters
- Beam: 13.5 meters
- Draft: 4 meters
- Speed: 28 knots
- Accomodations: 70 + 24 troops
A 2021 Janes report provides information on their weapons, combat management system, and ASW capability. If they emerge fully armed as illustrated, with an ASW capability, some would consider them corvettes or even light frigates.
