You must be joking about the TAS. I guess no photo in the world will overcome blinding bias.
Triple torpedo launchers aren't for offensive ASW, they are for defensive ASW. Clearly you do not understand this detail. Offensive ASW consists of helos, planes, and ASROC or VLA-type weapons with a standoff reach. When you allow a sub to get within range of your own torpedoes, you're already behind the eight-ball.
Bow sonars also aren't for offensive ASW, they are for defensive ASW. Perhaps you could be forgiven for not knowing that bow sonars, like all active sonars, can be heard by enemy subs long before they can pick up anything useful. And since they are active sonars, the only use they have is when they emit. And when they emit, they just told every sub for possibly hundreds of km around them that they are in the area. Those subs that do not want to be found will have left the area long before you can even hope to pick them up with a return ping. Medium frequency bow sonars are useful for tracking a known sub, getting a fix on a sub you know or suspect is close by, or to track incoming torpedoes or other nearby underwater objects.
I'm certain the 056 could refuel an ASW helo, but I would not be shocked at all if it could not rearm them. In fact I would be shocked if they could. They are not the same thing, didn't you know?
The 056 is a ship that is just large enough for enemy subs to want to spend time sinking, and just large enough to be able to mount some kind of defense against them. Defensive ASW is a deficiency of the K130, not some extraordinary find on the 056.

Let me help you two out and make it unambiguously clear to you how mooring works on these ships:
