First two patrols were odd with no contacts, but now I'm sold on RSRDC. Third time out, spotted two unescorted IJN Heavy Cruisers in 89 ft. of water, closed within 900 range and took them both out. Subsequent patrols have been great, stalking the shoals and grabbing tankers inbound.
Have to say this mod delivers on all levels, can't imagine playing the 'shoot em up' stock version again.
Happy Hunting! And thanks for the great mod Lurker! Lucky to have modders willing to take the time to make these sims so much more immersive and realistic.
