054B/next generation frigate

[Kejora]

True DP capability?
5-inchers are more on the anti-surface/gunfire support side of things, 3" is essentially a self-defense asset.

On the other hand US' Constellation class is moving to 57mm cannon. Also if this 100mm cannon has higher recoil than 76mm does that mean type 054b's hull might be bigger than 054a? It will be great if PLAN has a 6000-7000ton class frigate.

I don't think anybody really needs a DP gun that actually aren't good at either job. If the 054B can grow up to 6000mt, maybe they should go for the 130mm.

Do remember that the Type 054 uses the 100mm Type 210 gun, which it still keeps after the refit. So this ship hull is intended for the 100mm gun in the first place.

76mm feels like it would be less troublesome and more versatile than 100mm, seeing as it is much lighter and can even be used as a CIWS

Maybe they decided they need the land attack power? For a scenario in Taiwan/Korea/Japan maybe

For example, Russian A-190.01 has >80 RPM with 15.6kg shells, with ~twice the effective danger zone of the 76mm gun against both air and surface targets.
Unless you're specifically choosing gunfire support and surface targets - it may very well be the better of both worlds.

That is just a cost-savings measure as USA does not have a domestic modern naval gun between their 57mm and their 127mm.

They used OTO Melara 76mm on OHP Class

This is true - (1)it's sometimes forgotten, but 5"/62 is actually a very expensive weapon system. You can buy 056a corvette for the price of that gun - and it doesn't even have smart munitions yet.
(2)I suspect they were already ordered when LCS was still expected to be a 50-hull program(or at least such order was promised).
(3)Furthermore, US invests a lot in this gun(MAD FIRES, for example). They like that gun.
(4)For some important functions, it's probably indeed superior(close-in air defense, defeating swarms). If these functions are important enough for the customer - it's a logical choice. Burkes in particular are known to be less than ideal against swarms - so adding constellation to the mix brings a clear improvement.
(5)Finally - USN has more 5" guns afloat than anyone else anyways. If anything - it's in their institutional interest to clearly draw a line between burkes and constellations - or someone unnecessarily smart may ask what they're paying for(Burke).

I was thinking about this very gun which equips Russian corvettes to frigates.



You don't need to be a big ship to use this.

It depends on how large the 054B will be. If it's just around 5000t, I can see the point. For 6000+t, I still feel 130mm should be the better choice.
