It's early 1945 and the Essex carriers are testing out a new radar for detecting enemy ships. The radars give bearing, but not distance.
Driven by my newest script, you will get reports from the two Essex carriers on which sector enemy ships are detected in relation to each ship. Work the radios to listen to the morse code from each Essex and see if you can triangulate the position of the enemy ships without using the F10 map.
But wait, that's not all! You can also practice strafing aircraft sitting on Sapian, AAA on Rota, or spawning in Bandits.
