If you look at PN, it has a strategy of having a diverse fleet, with a few of each weight-class. From 200 tons, 500 tons, 1900 tons, 2400 tons, 3000 tons, and about 4000 tons (Type 54A in the pipeline).
This is a very standard position, except there is a gap. The gap is between the 500-600 ton Azmat and the ships 1900 ton Damen ships.
It will be interesting to see how this gap is fulfilled. Could a 1000-1200 ton ship close this gap?
An interesting issue here is that such a tonnage of ships would be relatively cheap as it would probably not have a helicopter or a helicopter deck and have local SSMs.
Could PN be looking to build an indigenous boat in this class? Something perhaps with:
1. torpedoes and sonar
2. 8x AShMs
3. Korkut CIWS
4. Indigenous SAM (rumored?)
This would be a very cheap solution, and would fit in near the middle of the tonnage classes in the PN fleet. The downside would be no helicopter, a cost-wise upside. But then, who needs helicopters when you have so many ASW aircraft and an increasing number of drones?
