When History Lies Beneath the Waves: How Modern Sonar Technology is Revolutionizing Naval Ordnance Recovery in Long Island Sound
Long Island Sound holds more than just maritime history—it harbors decades of naval ordnance from training exercises, wartime operations, and defensive installations. These included both coast artillery forts and underwater minefields, with two underwater minefields controlled from Fort H. G. Wright and Fort Terry that guarded the Sound. Today, advanced sonar technology is transforming how marine service companies locate and recover these historical naval artifacts safely and efficiently.
The Historical Context of Naval Ordnance in Long Island Sound
Naval and related facilities grew in importance in the Long Island Sound area from the Endicott era through World War II. In 1872 the New London Navy Yard was established on the present site of the Naval Submarine Base New London in Groton, Connecticut, and in 1915 submarines returned to the New London area at the base in Groton. In 1912 the Lake Torpedo Boat Company was established by Simon Lake in Bridgeport to build submarines, lasting until 1924.
The region’s strategic importance during both World Wars means that at least five 90 mm gun Anti-Motor Torpedo Boat (AMTB) batteries were built in the Long Island Sound area, and extensive naval testing occurred throughout the area. What was once a bustling fishing village was now occupied by a US Naval Torpedo Testing Range, as the US Navy started construction of the torpedo testing range in 1942 to increase testing and delivery of commercially manufactured torpedoes.
Modern Sonar Technology: The Game Changer
Today’s underwater ordnance recovery operations rely heavily on sophisticated sonar systems that far exceed the capabilities available during the original naval operations. Sonar is used for detecting unexploded ordnance (EOD) and conducting mine countermeasures (MCM) underwater, as locating unexploded bombs, mines, and torpedoes is critical for safety.
Commonly, side-scan sonar, either towed or boat-mounted, is used to scan large areas for anomalies. Once detected, an ROV equipped with imaging sonar is deployed to re-identify and approach the target to confirm if it’s an explosive. Synthetic Aperture Sonar is the leading edge in the sonar industry, as SAS systems are vital for spotting mines and provide very clear images of the seabed.
The technology has evolved to include advanced sonar systems, robotic arms, and specialized cranes that enable the precise location and recovery of torpedoes from the ocean floor. Modern sonar systems, including towed arrays and hull-mounted sensors, offer improved range and sensitivity.
The Recovery Process: Precision and Safety
Professional underwater ordnance removal requires a systematic approach. Advanced mine detection platforms, such as unmanned surface vehicles (USVs) or towed array sonar systems, scan the seabed for unexploded ordnance. Once located, focused mine neutralization systems or EOD platforms perform targeted clearance.
ROVs are becoming a support mechanism for highly advanced teams and can identify the ordnance and aid in the removal of the device without putting a diver at risk. ROVs can be deployed prior to the divers to map out safety routes and prevent divers from being in dangerous waters for too long, and they can explore near the surface of the water as well as great depths, and can detonate naval mines through controlled explosions without risking the lives of divers.

Why Professional Recovery Services Matter
The recovery of historical naval ordnance isn’t just about clearing waterways—it’s about environmental protection and public safety. Proper identification, removal, and disposal of UXOs are imperative to mitigate environmental risks and ensure the welfare and protection of both the environment and human populations. Many individual components of explosive ordnance can be harmful to the environment, as munition shells are often made with heavy metals such as copper, lead, antimony, and uranium, as well as other harmful compounds.
Underwater mines can pose a serious threat to many watercraft types, from shipping vessels, to cruise ships, and even to personal boats owned by the average person. Unexploded ordnance can pose a considerable risk to the environment.
The Future of Underwater Ordnance Recovery
As technology continues to advance, the capabilities for locating and recovering historical naval ordnance will only improve. Autonomous underwater vehicles equipped with advanced sonar systems will play a larger role in mine countermeasures, ASW, and surveillance. These platforms can operate in hazardous environments, reducing risks to human crews.
Mine counter-measures today use a myriad of modern technology such as unmanned systems, sonar, and advanced weaponry. This technological evolution ensures that companies like Miller Marine Services can continue to provide safe, efficient, and environmentally responsible recovery services throughout Long Island Sound and beyond.
For property owners, marine construction companies, or anyone who suspects the presence of underwater ordnance in Long Island waters, professional assessment and recovery services are not just recommended—they’re essential for safety, legal compliance, and environmental protection.
