There are several methods to get a solution that results in torpedoes on target. I’m not claiming this is the best but it works for me, doesn’t require a Microsoft spreadsheet, and is pretty accurate and quick. From the time we select our target and make our first course change to torpedo impact is less than 12 minutes.
- Select target
- Plot own course to intercept
- Plot target range and bearing
- Get speed estimate
- Plot 2nd target range and bearing
- Plot target AOB
- Sink target.
