The stunning screenshots are the first batch from an scenario named "Cans Only".
This is a simple ASuW-centered scenario addressing a hypothetical surface engagement exercise in the western Pacific in the summer of 2010. Two USN surface action groups, one of them including the amphibious ship USS Essex, must reach the Tokyo-Yukosuka area. Two JMSDF taskgroups act as OPFOR and must prevent them from doing so. There is no land-based air support or submarines; both sides must make do with their surface ships and what they can carry onboard. The Japanese have an advantage in numbers, but the US has more Aegis ships and lots more helicopters. The setup is 2-on-2 groups so there are plenty of decisions to make!
