Is using advanced defense technology to preserve historical shipwrecks a good use of resources?

Researchers unveiled high-resolution 3D models of the USS Monitor on March 7, 2026, following a successful 2025 sonar survey. The digital recreation offers a detailed look at the historic vessel without disturbing the site.

Why it matters

The survey provides a non-invasive way to track physical changes to the shipwreck over time. It offers a new method to study deep, inaccessible vessels that are otherwise difficult for human divers to reach.

The USS Monitor lies at a depth of 240 feet, where engineers used uncrewed underwater vehicles to capture 360-degree scans of the site. Northrop Grumman has now supported over seventy conservation projects nationwide.

The players

The Mariners' Museum and Park

This Newport News institution houses major salvaged components of the USS Monitor and serves as a center for maritime history.

Northrop Grumman

This aerospace and defense technology company has launched over seventy conservation and preservation projects.

Monitor National Marine Sanctuary

This federal program manages the protection and study of the USS Monitor wreckage located off the coast of North Carolina.

The details

The project utilized micro synthetic aperture sonar to generate images in low-visibility conditions. The scans captured the hull, internal structure, and the surrounding debris field of the ship.

1973: The USS Monitor shipwreck was discovered.
1975: The site was designated a national marine sanctuary.
September 2025: Researchers conducted the high-resolution sonar survey.
March 7, 2026: The digital models were publicly unveiled.

Culture Shift

Digital documentation represents a shift in historical preservation, moving from physical recovery toward non-invasive digital archiving. This evolution ensures the site remains protected as established by the 1975 designation of the USS Monitor as a national marine sanctuary.

Residents of Newport News can access the digital models to study the history of the USS Monitor from the Mariners' Museum and Park. These tools provide a new educational resource for the community without requiring direct interaction with the fragile underwater site.

The takeaway

Advancements in sonar allow researchers to study historic sites that were previously too deep or dangerous for human intervention. These digital tools serve as a permanent record, ensuring that maritime history is documented even as physical structures change or degrade.
