I purchased this for the H4 scenario between China and Japan. Sadly, while the SITREP includes data for the vessels involved and some of the weapons it neglects to include data for all the new guns on the Japanese and Chinese vessels. For example, the 052D destroyer has a new 130mm gun for which there are no published stats. The Chinese CIWS may have stats in some earlier SITREP, but I shouldn't have to buy that just to run the scenario I've already paid for.
A bit disappointing.
