AAW: pretty even as far as medium range missilery and AAW sensor fit are concerned. Delhi's have 2 more Orekh fire control radars which should give them a bit of an advantage in some scenarios. For close in work, against close, although the combination 2xAK630 plus 2x16 Barak may be superior to 2 Type 730 gun CIWS (although these guns are obviously superior to AK 630s).
AShW: 16 uran vice 16 C802, both have a single 100mm. Delhi's could possibly fire AShW torpedos from their quintuple 533mm tubes, 052B does not have similar capability given its lightweight torpodo tubes. Sensor fit: pretty even.
ASW: IMHO Delhi's have superior sensor fit plus the benefit of 2 helicopters versus the single helicopter of the 052B. Not sure whether 533mm heavy ASW torpedos of Delhi offer advantages over lightweight ASW torpedos of 052B. Delhi's 2 RBU 6000 seem a better close in ASW weapon than the Chinese ASW rocket launchers, but I don't know much specifics of the latter so that's just a gut feeling.
Hull: overall I thinks the 052B is a more modern platform, with lower RCS probably than Delhi
Machinery: entirely combarable. Delhi is all GTU and may be quieter are a result, which may be an advantages in ASW operations.
Just my 2c :coffee
For AAW I think 52B wins it, it has SA-N-12 Grizzly with has a range of 35 km against 38km against aircraft and 20km against anti-ship cruise missile. While the Delhi has the SA-N-7 Gadfly with max range at 25km. However
Navel Tech stated that the Gadfly will be replaced by the Trishul which has a range of 500m to 9km (any reasons for this?). 52B wins this one.
AshW 52B carries 16 YJ-83 (C-803) with has a max range of 150 km at Mach 1.5. the Delhi carries 16 SS-N-25 which has a range of 130 km at 300 meters per second.The Delhi carries two Sea King Mk.42B which can fire Sea Eagles at Mach 1.1+ with a 110 km range. Their single barrel guns seems equal with the Delhi one being able to fire at 30-50 rounds per min. and the 52B gun firing at 90 rounds per min. I think the 52B's wins this one.
For anti-missile the 52B carries 2 Type 730 CIWS with a max firing rate of ,600~5,800 rounds/min. while the Delhi is armed with four AK-630 with a firing rate of 5500 to 6000 rounds per minute out to about 2.5 to 5 km. The Delhi CIWS are going to be replace by the Barak point air defence missile system which has a range of 500m to 10km. Delhi wins this.
For ASW 52B's are fitted with 6 Yu-7 (Mk-46 Mod 1), two Type 75 twelve-barrel 240mm antisubmarine rocket launchers, four MRLs, and one KA-28. The Delhi's are fitted with 5 SET-65E, two RBU-6000, and two Sea King Mk.42B. Delhi wins this.
I don't know for surface strike and AAW the 52B's seems to have the better hand however for ASW and defence the Delhi is better. They both designs came out of the Sovremenny Class...
