What is the concept of a formidable warship (the one in Singapore)?

Singapore's powerful multi-functional missile frigate, judging from its published relevant information.

It should be a follow-up research and development plan of "NATO frigate replacement plan in the 1990s" (NFR-90).

A series of products of European "Next-generation * * * frigate plan" (Horizon).

Belonging to an air defense missile frigate.

The performance of the cattle class is obviously reduced. The air defense missile uses "Ziyuan-15" instead of (horizon) standard "Ziyuan -30". "Ziyuan-15" is a short-range air defense missile and cannot support "surface" air defense. Therefore, the operational performance of Niubi class as an air defense missile frigate is questionable.
