Vandenberg SFB Maritime Updates

Danger Zone 4 is always closed.

During launches, Vessel Safety Areas are strictly prohibited zones that drive the closure of most danger zones, except for Danger Zone #4. When a VSA is in effect, you'll notice more danger zones closed. While other areas outside the VSA, known as Vessel Hazard Areas, remain open for fishing, mariners should be aware of potential risks when entering these zones.

Although fishing is permitted in VHAs, it's crucial for mariners to understand the associated risks. Remember, the Frontier Control team is available on channels 6 and 16 to answer questions and offer help throughout the launch process.
