Introduction
NavAtlas is an interactive web application that visualizes naval movements and operations during World War II. It combines historical naval data with mapping technology to show how ships moved across the oceans, where they engaged in battles, and how naval strategies evolved throughout the war.
The application allows you to explore naval history through an interactive timeline, tracking individual ships and fleets as they move across the map. You can watch historical events unfold, examine specific naval operations in detail, and understand the scale and complexity of naval warfare during WWII.
What You Can Do
- Watch naval vessels move across the oceans during WWII
- Click on events to learn about specific naval actions
- Use different time speeds to see operations at various scales
- Focus on individual ships or entire fleets
- Explore both strategic overview and tactical detail views
- Navigate through precise dates and times to study specific moments
Current Coverage
NavAtlas currently includes Imperial Japanese Navy (IJN) battleships during 1945, with plans to expand coverage to include additional vessels, time periods, and naval forces from all theaters of WWII.
