I am not saying they should keep the Metel launchers at all. I am saying they probably won't use the Medvedka ASW missiles - as you suggested
And I am saying even the original Udaloy used Metel missiles... the later models had IR backup guidance for hitting ships as well as subs... the rocket that carried the torpedo to the location of the Submarine target also included a 300kg HE warhead so when a ship was the target it did not drop the torpedo and the combined 300kg missile warhead together with the torpedo warhead would be sufficient to deal with ships as well as subs. When subs were attacked the warhead and IR seeker on the carrier portion had no function.
Even the Udaloy was multifunction and could defend itself from enemy surface ships.
The new build ships and upgraded ships are all intended to be fully multirole, and I don't agree that the upgraded Udaloys will be anti sub only.
Even a corvette with a UKSK launcher can carry anti sub weapons, what it lacks is a decent Sonar because of its size even though it will have a helicopter able to perform the role an upgraded Udaloy together with corvettes would be excellent at hunting subs, but equally could be loaded with anti ship missiles or land attack missiles and perform a range of missions either with other ships or on its own.
In terms of air defence like a frigate or a corvette it is really only intended to defend itself, though a grouping of corvettes and/or frigates could work together and form a rather good defenceive group, a destroyer or cruiser is intended to defend itself and provide air defence for other ships nearby.
- as they are meant for small patrol boats.
And I am saying Uran was meant for small patrol boats too because at the time the alternative standard anti ship missiles were enormous... these days they are smaller and can be carried by small corvettes and patrol boats.
Despite being reclassified as frigates, the Udaloy frigates are still considered to be principal ships and will be armed as principal ships.
All their new ships and upgraded old ships are multirole now.
The days of dedicated ship types are over because of the unification of attack missiles into semi unified launchers.
They can also launch the RPK-6 Vodopad ASW missile from their 533mm torpedo tubes.
The 91ER1 and 91ER2 are torpedo tube and vertical launcher capable missiles... both are 533mm calibre, but the 91ER2 is designed for the UKSK launcher on ships and subs, while the 91ER1 is for launching from torpedo tubes in subs and on ships.
The Otvet is replacing the 91ER2... I don't know a lot about it other than its torpedo has a range of 20km which is about double the range of the old torpedo used... not sure if there are two model Otvets or they will keep using the 91ER1 from torpedo tubes.
Together with the two helicopters they will have a formidable long range ASW capability.
It already had an excellent sonar system so I would expect it would be upgraded and likely be a new system they will fit to their new Destroyers to make them fully multirole anti sub capable...
[quute]Being fitted with the UKSK launchers (probably UKSK-M) gives them even more options and can easily use Tsirkon and Oniks missiles if required. But as Big_Gazza suggested those new missile launcher fittings on the Chabanenko could be for something far more sinister! Smile[/quote]
There are two mounts on either side and the article said the Uran load out has been doubled from the previous 8 missiles (one quad launcher on each side) to 16 missiles (presumably two quad launchers on each side)... which explains the two launch mounts...
The Harpoon pattern of flight is straight ahead towards it's target, and the highest sophistication it can present is making a jump&attack from the angle while descending.
Ch-35 shoot in salvos is preprogrammed for a different approach to the target, maneuver, change the path&altitude, and the salvo communicates itself and adjusts the flight path to attack from multiple directions at the same time. They even share the aiming points together, so a salvo can be distributed in a way that some attack engine room, the others weapon or radar systems, etc.
The amusing thing is that the Americans go on about how their carriers are impossible to find because they don't turn on their radar.... the wolf pack attack method of Soviet and Russian attack missiles means only one missile uses its radar to scan for targets and passes on target data to other missiles flying in radio silence so the fleet will detect one missile via radar and datalink emissions... even if they shoot it down the missiles will send up a replacement, but that replacement missile and all the other missiles in the attack don't need to scan for targets again... they already know what they are attacking and will attack in radar silence till they get very close... their operational height is reported to be between 2 and 3 metres above the wave crests... it is one of the reasons the naval Pantsir-M is required to hit targets as low as 2m above the water with missiles...
