Defence comparison of Indian Kolkata class destroyer and Chinese Type 054A+ Frigate
Defence is one of the most important parameters of any Naval ship. A ship quality is mostly based on it defence not its attack.
For defence against fighter jets Surface to air missiles are mounted on the ship and to protect against the incoming missiles Close in weapon system (CIWS) are mounted on it.
Here is a comparison of Indian front line ship Kolata class destroyer and Chinese Type 054A+ Frigate which Pakistan ordered (4 of them)
Remind you we are comparing a destroyer with a frigate so you would expect that in every case the destroyers must overcome the frigate by far margin but the result is something else. Not much difference. Either the modern Chinese frigate is close to destroyer or Indian Destroyer is less armed for a destroyer
∆.Displacement
Kolkata class destroyer: 7500 tons
Type 054A+ Frigate: 4100 tons
∆.Surface to air Missiles
Indian Kolkata class destroyer uses Israel made Barak 8 missiles. 4x8 cells (32) are mounted on the ship. Barak 8 has a max range of 90 km.
Chinese Type 054A+ is mounted with 1x32 cells HQ-16 missiles of Naval variant. HQ-16 (Naval variant) has a max range of 75 km.
Conclusion:
As a destroyer you expect Kolkata class to be equipped with more than 32 missiles with range more than 120-130 km. While Type 054A+ Frigate to be equipped with 35-40 km range with less than 32 missiles but it ant happening here.
Close in Weapon System (CIWS)
CIWS engaged upcoming antiship missiles
Kolkata class:
Kolkata class consists of 1x4 Soviet/Russian made 1ST generation AK-630 CIWS. Develop in the 1970. Russia now uses Kashtan (Chestnut) CIWS which is the best CIWS in the world. AK-630 1st Generation is still exported to other countries like India and it is also used by Russia to protect its smaller ships like corvettes. It can effectively detect upcoming missile traveling at a speed of mach 2.
Fire rate: 5000 rounds per minute
Range: 4 km
Develop: 1970
Type 054A+
Type 054A+ is mounted with Type 1130 Third generation CIWS which is one of the best CIWS that it is able to intercept incoming anti-ship missiles up to a speed of Mach 4 with a 96% success rate.
Fire rate: 11,000 rounds per minute
Range: 3 km
Develop: late 2000
Type 054 consists of 3 variants. The early Type 054 consists of same type of CIWS which is mounted on Kolkata class i.e. 4x 1ST generation AK-630 CIWS. Later in Type 054A Chinese made 2nd generation Type 730 CIWS were used. 2x type 730. These 2 can provide more safety than those old 1st generation 4 AK-630 CIWS. Later in Type 054A+ 3rd generation Type 1130 CIWS is used.
Not only 2 x type 1130 ciws are mounted on type 054A+ frigate 2 × Type 726-4 18-tube decoy rocket launchers are also mounted on it. decoy launching system provide 360° coverage, and will effectively counter advanced threats like small range gate Radio Frequency (RF) missiles, imaging Infra-Red (IR) seekers missiles, and advanced next generation torpedoes. Defense against multiple missiles and torpedoes requires fast response and utilization of advanced tactics supporting the latest in decoy technologies
Conclusion
Despite being a frigate Type054A+ CIWS are better than Kolkata class destroyer. Not in quality but also in quantity

Article failed to mention that the Kolkata class carries Brahmos the world's most deadly cruise missile.
