The data below speak to her ability to patrol SLOCs, relative to Type 21, F22P, Type 053H3. Here you see the advantage of a design tailored to working with carrier groups (which cruise at relatively high ave. speeds). She retains a full sensor and command suite as well as a full ASW warfare weapons suite, including facilities for 2 helicopters. The only thing lacking (and quickly mounted if the need arises) is: 2x2 or 2x4 Harpoon launchers and a RAM launcher. Those are pretty much plug-and-play for this ship.
