Phù Long Range Rear Lighthouse

Also known as: Phù Long Range Rear (Hải Phòng Approach D)

Phù Long Range Rear is an active aid to navigation located within the intricate waterways leading to Haiphong, Vietnam's principal northern port. This structure helps guide vessels through a complex network of channels and mudflats typical of a river delta meeting the sea. Its purpose is to assist ships navigating the busy shipping lanes into Haiphong. The lighthouse's operation relates to the need for precise navigational aids in the Gulf of Tonkin to prevent groundings and collisions in the often-murky waters. It remains a functional component of maritime safety in the region.

Why it matters: This range light is critical for ships entering and departing Haiphong, marking the precise alignment needed to navigate the complex channels of the Hải Phòng Approach D and avoid shallow areas.
