I've run the campaign six times now and most of the ships in the OB for both sides have made it onto a table top. That being the case, I've needed to provide SDS at some point for all the ships involved. I consider myself fortunate in that I have every ODGW product with SDS including the Deluxe SDS. It turns out that I have needed all those resources to get the Japanese on the table with each ship having its own SDS. DTMB provides all the SDS for the Allies, but not for the Japanese. By combing through DTMB, GQIII.3 and TSC I was able to find all the Japanese SDS but two Hatsuharu class DDs; the Wakaba and the Hatsushimo.
I used Deluxe SDS to provide the missing SDS; but in an earlier query on the TSC forum I asked for and received a reply to which SDS should be used for the campaign. The word was, use the SDS provided by the campaign; so my solution to the missing SDS is not the best one possible. I know that the ODGW staff provide additional SDS on the forum from time to time and I'm asking that they do that again for the missing DD's SDS. That way they will fulfill the promise made in rule 1.2 of DTMB that all ship's SDS are available on the web site.
