So, as a follow on from my previous post lets consider two more classes of frigates (for theoretical purposes at least). You guys can review these two designs as they are up and coming and pretty well regarded by experts in the field. These displace between 3500 and 4500 tons and are well equipped and armed. Sensor suites wise - I believe the Korean choice beats the Russian choice simply because Korea more or less copied the Raytheon systems (even AEGIS system in their much larger destroyers).
Cost is very reasonable for both (say about 250 to 300 million for each example). The Indians have asked the Russians for design ToT on the latter.
Please read the material (may be boring at first). But without reviewing the choices and options offered we cannot discuss.
I am _NOT_ going to discuss FREMM frigates or Germany's F125 frigate here, these at 600 to 700 million a copy are way out of our price range.

Daegu (Taegu) Republic of Korea Navy FFX-II class
South Korea's defense procurement agency Defense Acquisition Program Administration (DAPA) placed an order with Hyundai Heavy & Industries (HHI) on Tuesday to build two Daegu-class FFX-II frigates ahead of schedule to support the ailing local shipbuilding industry.

The two FFX-II vessels will be the third and fourth in the series. Daewoo Shipbuilding & Marine Engineering (DSME) launched the lead ship of the new Daegu-class FFX-II (also known as FFX batch II) frigate for the Republic of Korea Navy (ROK Navy) on June 2, 2016. Key updates of the Batch II over the
ASW-focused Batch I include VLS and full electric propulsion system, as well as a larger hangar that can accomodate a 10-ton helicopter.
FFX-II batch II is the first South Korean warship to be fitted with
DRS Hybrid Electric Drive system, coupled with Rolls-Royce MT-30 gas turbine engine for CODLAG integrated full-electric propulsion. This configuration is shared with the US Navy's LCS and Zumwalt destroyers, as well as with the Royal Navy's QE aircraft carriers and future Type 26 GCS. In terms of engine technology and acoustic reduction technology, this makes FFX-II one of the most advanced and 'reduced accoustic signature' ASW frigates among western navies.
Contacted in June by
Navy Recognition, a DSME reprensentative said that first ship of the class ROKS-818,
Daegu will be delivered to ROK Navy in late 2017 and will be commissioned in late 2018.
FFX-II batch II is not fitted with Mk 41 VLS but with KVLS meaning it will deploy Korean missiles (most probably designed by LIG Nex 1 such as the Cheolmae-2 medium-range air defense missile, Hong Sang Eo anti-submarine rocket, and possibly the Hyunmoo-3 series of land attack cruise missiles). The Korean guided munitions were 'inspired' by their American counterparts, some licensed and some not.
Daegu-class FFX-II frigate main specifications:
Displacement (Full): Abt. 2800 (3,600)
Length/ Beam: 122m / 14m
Max. Speed: 30 kts
Complement: 120 sailors
Major weapons: 5” Main gun (K Mk.45 Mod 4) / 20mm CIWS (Phalanx Block 1B) / KVLS (16 cells)
Propulsion: CODLOG

DSME[5] Building
The Daegu-class is a development of the
Incheon-class frigate (FFX-1), with many similarities, and many improvements. The FFX-1 itself was a follow on from the Ulsan class (Our lead ship BNS BangaBandhu was a modified Ulsan class). Modifications to the Incheon-class include a 16-cell
Korean Vertical Launching System (K-VLS) that will be able to deploy the
Cheolmae-2 air defense missile,
Hong Sang Eo anti-submarine missile, and
Haeseong-II and
Hyunmoo-3 land attack
cruise missiles.

There will be a larger hangar for a 10-ton helicopter.

all-electric, with the twin gas turbine layout replaced with a single
Rolls Royce MT30 turbine engine.

There are variations on this design. Thai and Philippine navy frigates are being built by Daewoo and Hyundai to a slightly different superstructure.
I will cover the Admiral Grigorovich-class in a follow on post later.
Admiral Grigorovich-class (Project 11356) guided-missile stealth frigate
Russia to resume the construction of the "last three" Project 11356 frigates in 2018
The United Shipbuilding Corporation (USC) will resume the construction of the last three Project 11356 frigates in 2018 (Project 11356 Admiral Grigorovich class is slightly modified for export compared to Project 11350 Admiral Gorshkov class).
Earlier, the construction of these ships was suspended due to Kiev's refusal to supply gas turbine power plants. The decision to resume the work was made following the preliminary testing of the latest Russian gas turbine units M70FRU and M90FR. According to experts, the advent of these ships will significantly expand the Navy’s capabilities in the Mediterranean Sea, the Central and North Atlantic, and the Arctic zone, the newspaper Izvestia writes.

At present, two of the six ordered ships of this class are operational with the Navy. The frigates Admiral Grigorovich and Admiral Essen are part of the Black Sea Fleet. Admiral Makarov is undergoing the official tests. The remaining three frigates of the "Admiral" series - Butakov, Istomin, and Kornilov - are currently mothballed in varying degrees of completion at the Kaliningrad-based Yantar Shipyard. They were intended for the Baltic Fleet. Their construction was frozen because of Ukraine's refusal to supply the DS71 and D090 power plants manufactured by Zorya-Mashproekt, Nikolaev, Ukraine and previously paid by Russia. It was assumed that the "Admirals" would be sold to the Indian Navy because of the inability to complete them. Aleksey Rakhmanov, the head of the United Shipbuilding Corporation, told Izvestia that the construction of the ships will be resumed in 2018, after the appropriate tests and follow-on development to accommodate the new power plants.
"The decision has been made and R&D work will be required," explained Rakhmanov. However, due to the fact that design proceeded with regard to the groundwork laid by Russian gas turbine builders, no major modifications to the architecture of the ships will be needed. "We do not think that these R&D works will be so significant as to throw us back a few years ago."

As noted by Rakhmanov, the timing depends not only on gas turbine units - the shipbuilders will have to resume contracts on all major systems.
"Therefore, it is very important here that we are able to comply with the warranty periods, the service life of equipment and the corresponding storage life," the head of USC said.
As Izvestia was told at the Navy's Main HQ, the tandem power plant configuration of two M70FRU gas turbine engines is being considered as the core project. According to preliminary calculations, this should ensure the maximum power output of 14,000 hp. In this case, the ship will be able to move at a speed of 30 knots and the cruising range will be 4850 nautical miles (9,000 km). This is quite enough to go from the Baltic Fleet’s main base at Baltiysk to Russia’s Tartus naval base in Syria without fuel replenishment.

Expert Alexander Mozgovoy told Izvestia that the decision to complete the Project 11356 frigates was welcome.
"Our Navy really needs them and we would have lost three good ships in case of selling them to India," said the expert.
"These are general-purpose ships that can operate in the Mediterranean, in the central Atlantic and in the north. We are in desperate need of such ships today as all the large Soviet-era ships are badly worn and their service life is nearing the end. In fact, there is no alternative to the Project 11356 frigates."
Project 11356 frigates are designed to attack enemy surface ships and submarines both in the near and far maritime zones, counter air targets, both independently and as part of a task force. Frigates of this type are armed with a 100mm A-190 gun, strike and air defense missile systems, including Kalibr and Shtil, torpedoes. The ship can carry a Kamov Ka-27 helicopter and its versions. The ship's displacement is 3620 tons and its length is 124.8 meters. The full speed is 30 knots and the cruising range is 4850 miles.
Comment -
According to available information, the completion for the Russian Navy of three frigates of the modified project 11356 with the Russian all-mode main power plant based on gas turbine engines M70FRU is included in the draft State Armament Program for 2018-2025.
