They are two different projects, but it seems more emphasis has been put on Project 20380 Steregushchy. It more or less symbolizes Russian Navy's new doctrine, i.e maintaining a smaller but more effective force by reducing number of combattants while introducing more automated systems and more modern C4ISR elements, under hands of less but professional, well trained personnel. Project 22350 heavily depends on the success of Steregushchy, since it will take a lot of technology from him.
By the way, for now Yakhont is only a "future option" for Steregushchy -let alone Pr 22350 Gorshkov-
meaning waiting for funding and solving integration issues. First Steregushchy class corvettes will use 3M24E Uran (SS-N-25 "Switchblade") anti ship missiles in two quad KT-184 launchers (similar to Mk141 launchers of RGM-84 Harpoon).
As for the main gun, 130mm/?? AK-130 will be used in Project 22350, while 100mm/70 A-190 was selected for Project 20380 Steregushchy. Today 57mm/70 Bofors and 76mm/62 Oto Melara are almost standard guns for western built corvette and patrol boats, the latter even installed on some succesful frigate designs.
I'm not sure about Project 22350, but Project 20380 Steregushchy uses one Kashtan CIWS. There are future plans to install a second Kashtan abaft helicopter hangar.
I'm very skeptical about Project 20380 Steregushchy's living conditions for personnel, since he operates a good load of weapon systems, such as a large caliber (100mm) gun with two 30mm gatling guns plus two 14.5mm, 8 x SSM's ASROCsky rockets (RPK-9 Medvedka-E), Kashtan, 2 gas turbines and two diesels and a helicopter hangar on a 1,900t hull. Today's corvette design trends put heavy emphasis on personnel living and operating standards, since these boats may well remain on patrol for 2-3 weeks without replenishment. Russians are not famous for putting ergonomy on top of design requirements, but it is a "must" for a navy undergoing modernization, reconstruction and rehabilitation, not to mention introducing voluntary service and professionalism.
