Diesel Kriegsmarine wargames and raiding across oceans

What were the highlights of the wargames exploring an all-diesel Kriegsmarine?

Diesel-powered German groups could raid far from home, including the Indian Ocean, while another group used the Panama Canal to reach the Pacific. Reaching Japan for fuel raised the possibility of a circuit around the world.

One contributor recalls counterfactual naval wargames that included mixed diesel-and-turbine Lion-class designs and long-range German raiding groups. One group combines a carrier, two Scharnhorst-type ships and four smaller cruisers with variations of 6-inch armament. The battleships have different batteries, one with nine 11-inch guns and another with six 15-inch guns. Its arrival in the Indian Ocean causes serious trouble for the opposing side. Another player's group books passage through the Panama Canal and moves toward the Pacific. Reaching Japan for refuelling creates the possibility of a much longer circuit. These are game outcomes that explore how propulsion endurance and access to ports interact.
