Ah yes, They are closer to SHORAD than medium range SAMs
Gulf of Aden missions are a nice to have for the next 10 years. It's good for some training, but the Western Pacific is where any high-intensity conflict will be decided. If you put gas turbines on a Frigate, you'll get enough speed to keep up with carrier groups and also the inherent smoothness/quietness.
I agree ships are getting larger, but the they don't have to grow that much in size
Other navies have a requirement for very long-range ships because they have to travel vast distances, whereas Chinese ships do not
When I was referring to the OH Perry, I was referring to both its size and speed, given that it was using gas turbines
Gas turbines is the world wide norm for a frigate, having all diesel engines is the exception and the outlier. The classes of frigates in this world that are all diesel can be counted by a single hand.
Ships are getting larger, and its not because of very long range. Its because a larger ship takes better battle damage, is more comfortable to live in for longer periods, and is able to carry larger equipment, sensors, weapons, computing back ends, etc,.
Ships are growing bigger and yet I don't see navies traveling that far. When they do, its still ranges that can still be covered by OHP sized boats. The Admiral Gorshkov is closer to the size of 054A than a 052D, somewhere in between, and yet is able to circumvent the world. European navies travel mostly to the Atlantic, that's not very far. Going down to the Indian Ocean via Suez Canal, that ain't far either.
