Testing an all-forward cruiser at the River Plate

The experiment places a Royal Navy heavy cruiser and two light cruisers against a German heavy cruiser in a River Plate-style encounter. The central design question is whether concentrating the main battery forward can improve a cruiser without sacrificing the operational flexibility cruisers need. The simulated ships are deliberately approximate rather than literal reconstructions, so the exercise tests design trade-offs rather than predicting the historical battle. The opening establishes the assumptions that shape the later action and its limits.
