The Gepard is 2200 tons.
The definitions are not written in stone, Each Navy follows its own criteria. The Indian navy considers the Kamorta ASW ships with more than 3000 tons as corvettes. Blue water navies normally tend to consider those classifications by using heavier tonnage. Littoral navies will do the opposite. Another way to define the ship is according to the weapon systems.
In my opinion light frigate fits well since the Vietnamese navy is a littoral navy and the weapon systems of the Gepard are typical of a frigate and includes a helicopter also. Full frigate I would say is for 3000 tons and up and a corvette should be less than 2000 tons.
Very interesting development. I'd love to see Vietnam's Navy conducting more naval exercises with JMSDF.
At 2200 tonnes, its at the same level as our Abukuma Class Light Destroyer Escorts, which has a tonnage displacement of around 2500.
Abukuma Class,
