Below a schematic for the Meko 360 H1 and an Thales image of H2. When compared to a graphic of the basic MEKO A200, the similarities are apparent.
More on MEKO here
IIRC, one the MEKOs with an Aspide launcher in the rear, these could carry up to 24 rounds: 8 in the launcher, 2×8 reloads stored vertically in a loading system underneath the launcher. I think that whole package was the size of a single weapons container. This space fits 2×1 8-cell Mk41 tactical.
Keeping in mind the eventual F123 has 4x Mk41, the stretched Meko 360 in the artist impression may well have a similar fit, which makes 2 forward of the bridge and 2 more in the rear sound plausible to me, possibly more so then 2 forward and 4 in the rear. F123 is designed for 2 helicopters, so I would expect the stretched Meko 360 to be like the 360H2 variant, with a large hangar. Which would seem at odds with using that space in the superstructure for an extra couple of Mk41 (even with a stretch).
But this is just reasoning, not evident. May I suggest both gentlemen attempt to upload the drawing/image they are referring to onto the board?
Anyway just a correction, Aradu has a single helo where as the Argentine vessels are actually a two helo carrier, the last pic is how this works, rather interesting.
I thought that’s what I said.
H1 > single-door hangar for one helicopter > Nigeria
H2 > single-door hangar for two helcopters > Argentina
Below: evolutionary step from MEKO360 to F123/F124/Meko200TN. Note the APAR-like antennea on the forward mainmast (which isn’t APAR because else there would be no need for 2 Signaal STIR.)

Deliverer it is then :p
The MEKO® 360 can be supplied in two versions. The H1 version has a hangar for an on-board helicopter whilst the hangar on the H2 version is large enough to accommodate two helicopters, which can be maintained on board.

The Argentinian MKEO 360 ARA is the H2 version, the Nigerian MEKO 360 NN is the H1 version.

Both Nigerian and Argentinian vessels have a single hangar door. The rear superstructure of the Nigerian H1 is much narrower (to accommodate several single Otomat launchers next to the rear superstructure) than that of the Argentinian H2 (which had 2×4 MM40 on top of the midship-superstructure.)

I apologize if I have offended South Korean sensitivities. Now, lets get back to the Mosaic corvette design.
Just as a sidenote, Okpo is the name of the yard. It’s neither the project name or the shipname.
Gwanggaeto the Great class destroyers (at the time of their delivery known as KDX-1 Okpo class)
I was more concerned with the cost amounts for the P17
Its tarantuls not tarantulas. My point is even if adding the 8 Uran/Klub costs 25 million. The total cost of the P-28 would only rise to 200 million per ship. The ship would have a decent AShW capabilty, a modest AAW capability (Barak-1+Ak-630’s) and A terrific ASW capability. The F-22p costs something like 187.5 mil per ship with ToT (I am not sure whats the purpose of one ship ToT but even otherwise it would not cost less than 130-140 mil per ship.) and is not as capable while the milgem corvettes are smaller boats with broadly similar AAW and AShW capabilities and weaker ASW capabilities also cost 200 mil. 200 mil per ship is nothing when the GOI is ready to spend upto 800 mil per P-17a.
From what I understand a lot of the money for P28 has gone into singnature reduction (radar, thermal, noise etc). In that area – and probably in areas such as damage control, it should compared much more favoarably to F22P. Making it much harder to find, to target and to sink. Thus allowing it greater surviability even in the the absense of AShM. Look at the Italian Commandante class: no AShM, no SAM, limited ASW. It may be better to do one thing proper (e.g. ASW) than a lot of things so-so.
With respect to these dollar amounts, are they in any kind of constant dollar figure? Or are we comparing dollar cost in 2000 with that in 2008 straight up (while the dollar has gone down a lot e.g. relative to euro, which may lead to inflated unit prices if expressed in dollar.)
The kora and kukri class were also designed by NDB. They were supposed to be for ASW purposes but ended up being long ranged tarantuls and little else. Without urans P-28 will require P-25 as escort and completely beats the purpose of the ship. The Pauk class was good enough otherwise.
If P28 are optimized for ASW then one should look at how e.g. the US Navy used the Spruances in combination with other (more noisy) combat ships. Escorting – at least in the traditional sense – is not going to happen as Kukri’s/Kora’s would be load and noisy compared to the P28. More likely they would be somewhere ‘nearby’, this being within 130km Uran missile range (but most likely some 30-60km away).
I have a question guys…
I believe we would have to know more about the acoustic signature reduction methods employed in this vessel as well as the kind of sonar and countermeasures it has on board. Would also like to know about the kind of torpedoes it would carry. Remember that this vessel’s primary threat comes from underwater than the surface ships.
In primary weapons fit, it seems to follow the pattern of the russian Grisha class: DP gun, light guns, SAM, 2x RBU, 2x twin 533mm TR-ASW. Modern day equivalents for the ASW weapons can be identified from the Talwar class:
– the RPK-8 system, with a 12 barreled RBU-6000 ASW rocket launcher to fire 212mm homing 90R anti-submarine rockets or unguided RGB-60 depth charges.
– 2 twin 533mm DTA-53-11356 fixed torpedo tube launchers are fitted amidships and fire the SET-65E/53-65KE torpedoes.
– Purga anti-submarine fire-control system provides control for both the RBU-6000 and DTA-53 launchers.
Clearly, in P28, Larsen & Tubro built derivatives of the RBU and the torpedo-tubes will be used. Their website says these tubes can fire russian torpedoes (CET 65E [sic] anti submarine and CET 53-65 KE [sic] anti ship) as well as indigenous torpedoes such as Takshak, Kazind, etc. See here The DRDO with the help of Larsen & Toubro also developed a microprocessor controlled Triple tube torpedo launcher for the Indian Navy’s ships as well as Towed torpedo decoy (TOTED)
The 533mm torpedo tubes should be able to fire ss-n-15 (starfish) and this possibiliy is mentioned with the Delhi class, together with information on the russian torpedoes in use:
SET-65E: anti-submarine, active & passive homing torpedo to 8.1n miles; 15 km at 40 knots with a 205 kg warhead
SET 53-65KE; passive wake homing torpedo to 10.3n miles; 19 km at 45 knots with a 305 kg warhead.
Incidentally, Delhi carries up to 192 rockets for its 2 RBU-6000 (2x 96). A smaller ship like Grisha would carry 144 rounds (2x 72) The unguided RGB-60 does 500-5800m to a depth of 500m and has a 25-31kg HE warhead. It can also be used for shore bombardment. The homing 90RE does 600-4300m but to a depth of 1000m with a smaller 19,5 kg shaped charge warhead.
For the P17, it was mentioned in relation to the torpedo tubes that it was entirely possible that 91RE2 ASW missile would be employed for anti-submarine operations, given the flexibility of the Klub system. (Also mentioned for Delhi, by the way.) Obviously, if indeed torpedo tube launched, then this should be 91RE1. If this is so, then that’s also a possibiliy for P28.
Sonars: likely BEL HUMSA (Hull Mounted Sonar Array) and either the HUMVAAD Variable depth sonar or the NAGAN towed array sonar. Alternatively e.g. Thales Advanced Towed Array System or SSN-137 VDS (French)
I believe those torpedo tubes are 324 mm similar to Brahmaptura’s?
http://drdo.org/pub/techfocus/oct2000/underwater.htm
The model has twin tubes and they look relatively long. Much like the twin 533mm tubes on the ABHAY {PAUK II} and TALWAR {KRIVAK III} classes. Rajput and Delhi classes also employ heavyweights, but in a single quintuple mount.
Incidentally, even if the torpedo tubes were not used to fire missiles, she could still fire torpedoes in anti-ship role. Even something like Shkval. I.e. it doesn’t necessarily need antiship missiles to be dangerous.
Excuse me if I’m missing some cynicism here since caffein in my blood had dropped radically, but that’s a hard to imagine, let alone consider, way of launching surface-to-surface missiles; especially for a ship which has a much orthodox design with minimum or no innovation.
AShM launchers are not visible on Neustrashimy, because there is none. The ships are fitted-but-not-with Kh-35 Uran’s.
SS-N-15 (Starfish) ? Both sub-launched and surface-launched versions exist. The surface-launched versions are used by the Slava, Kirov, Neustrashimyy and Udaloy classes, while the sub-launched versions are used by the Akula, Oscar, Typhoon, Kilo and Borei classes.
(Neustrashimy: only 1 ship in service, one other possibly being completed)
Have any of you considered the possibility that it has some AShMs but that these are launched from the torpedo tubes (they look like 533mm heavyweight DP tubes, not the 324mm ASW tubes, and so should be able to handle Klub-S variants)? :diablo:
Compare e.g. Neustrashimy > no visible AShM launchers
