A separately recorded 1930 version of the engagement adds radar to the scenario. In that replay, radar makes a substantial difference for the Japanese force and brings it somewhat closer to the British squadron, although it does not erase the imbalance. Because this is an alternate simulation, the result is a controlled comparison rather than a claim about an actual battle. The result shows how a change in sensor and fire-control technology can alter the tactical relationship between otherwise similar fleet designs.

Radar narrows the simulated fleet balance
A separate 1930 replay suggests that radar would improve Japanese performance and modestly reduce the British advantage.
