That's because they're supposed to be frigates. Stop thinking of them as well-armed corvettes and start thinking of them as underweight frigates. If Russia and Israel
could build 3000-4000t hulls cheaply, they would have. But they can't so they're relegating themselves to corvette-sized hulls.
The 056 is a light frigate in a light frigate hull. The Sa'ar V and Russian corvettes are full-blown frigates packed into a corvette's hull with compromises in so many critical areas that no other navy deems it acceptable to do what they did.
Most of what you think are current mainstream corvette designs are actually downsized frigates. I've told you this already, multiple times. Those corvettes are not "good" corvettes, they're substandard frigates. If Russia could build frigates properly, they would much rather have those than the compromised cramped "corvettes' they currently have.
Why don't you read about the
of USN 7th Fleet sailors yourself? Here, let me quote it for you:
"Sailors in Mims’s engineering department reported 'extreme work hours,' with one telling investigators they slept about three hours a night."
How do you solve sleep deprivation on a ship? You let the sailors go to sleep, which means you need other sailors to replace them, which means you need more bunks for those other sailors, which means your ship cannot be corvette-sized if you want a frigate's weapons suite, unless you are willing to compromise your crew's comfort and combat effectiveness by forcing them to be awake for 21 hours a day.
What does the flight altitude of JH-7s have to do with your argument? How are they even related to each other?
I also don't follow your logic with the Buyan. Why do you think China needs the Buyan again? They have DF-15Bs and DF-16s, and JH-7As with YJ-83Ks, YJ-91s, and YJ-12s. What use could China possibly have for a non-versatile and loitering-incapable missile truck? What does a "1500km range cruise missile with Mach 0.9 speed" have to do with whether or not China should introduce their version of a Buyan?
That's supersonic. And they're late. Russia and China already had air-launched supersonic AShMs decades ago with the Kh-31 and YJ-12. Get back to me when it becomes hypersonic.
You implied the 056 should possess additional capabilities even though that's not their job. That's exactly like forcing them to possess HQ-16s for air-defence when their job isn't air-defence.
They'll get an 8-cell HQ-10A when the time for upgrades come. That's sufficient for self-defence which is the only thing they need during a war as medium to long-range air-defence will be handled by 054As, 052Ds and 055s.
The Kilos and Soryus would have a hard time penetrating the 056's defences given the advanced capabilities of the HQ-10. They also won't be alive for long after the 056A rams an ASROC up their behind.
And no, 056s will not be expected to face "corvettes" (not real corvettes but undersized frigates) from other countries as that's the 054A and 052D's job. If the 056s find themselves in the unlikely situation where they need to take on an enemy pseudo-frigate, their YJ-83Ks are decent enough and their HQ-10s will hold off anything the enemy can throw at them. Also, 056s will not be deployed alone in a war, they will be in groups so it won't just be one 8-cell HQ-10 but multiple sets.
Just for clarity's sake, why don't you list the extra capabilities that you want the PLAN to shove inside the 056 hull? Here, let me start if off for you:
- Land-attack cruise missile launch capability
- ???
