Edge
Sparton Corporation: Expanding U.S. Naval Contracts
Sparton Corporation, a key player in the North America Sonobuoy Market, has been a 
long- standing supplier of sonobuoys and underwater acoustic systems for naval 
defense and anti-submarine missions.
 March 2024: Sparton secured a $106.4 million contract from the U.S. Navy for 
the AN/SSQ-125 modified high-duty cycle sonobuoys.
 The contract includes the manufacturing of up to 20,000 sonobuoys, with 
production taking place in Florida and Indiana and an expected completion 
by March 2026.
 Sparton is investing heavily in high-frequency sonar arrays, data fusion 
algorithms, and AI-powered underwater detection systems to enhance naval 
surveillance.
Lockheed Martin: Strengthening ASW Operations
Lockheed Martin is a global leader in defense technology, offering cutting-edge sonar 
and surveillance systems to the U.S. military. The company’s sonobuoys are widely 
used in airborne ASW operations, significantly improving the real-time tracking of 
enemy submarines.
 April 2022: Lockheed Martin, in collaboration with ERAPSCO, secured a 
$222 million contract from the Naval Air Systems Command.
 The contract involves the production of 18,000 AN/SSQ-125A multi-
static sonobuoys, which are crucial for airborne ASW operations.
 Lockheed’s multi-static and active-passive sonar technologies provide high- 
resolution underwater mapping, helping to detect and classify submarines 
more efficiently.

Trends Shaping the North America Sonobuoy Market
1.AI-Enabled Sonar Technologies
AI and machine learning (ML)-powered sonar systems are enhancing underwater 
surveillance. These systems process vast amounts of acoustic data, improving 
submarine detection accuracy and reducing false alarms.
 By 2026, over 70% of newly deployed sonobuoys will integrate AI-driven 
signal processing, reducing detection errors by up to 40%.
2.Rising Investment in Multi-Static Sonobuoys
Multi-static sonar technology is gaining traction due to its ability to increase detection 
range and provide enhanced target tracking. This technology is highly effective in deep-
sea environments, where traditional sonar systems often struggle.
 The U.S. Navy has committed over $500 million in the next five years to 
advance multi-static sonobuoy networks, particularly for Pacific and Atlantic 
fleet operations.
3.Adoption of Next-Gen Acoustic Sensors
Future sonobuoys will feature miniaturized, high-frequency acoustic sensors that can 
operate in extreme underwater conditions. These sensors will improve passive 
listening capabilities, enabling the detection of stealth submarines with greater 
accuracy.
 Sparton and Lockheed Martin are developing hybrid acoustic-
electromagnetic sensors, expected to enter full-scale production by 2025.
Growth Opportunities in the North America Sonobuoy 
Industry
 Expanding Defense Budgets: The U.S. Navy’s FY 2025 budget includes a $1.3 
billion
increase for ASW research, benefiting sonobuoy manufacturers.
 Increasing Demand for Anti-Submarine Warfare: With growing concerns over 
foreign submarine activity in the Atlantic and Pacific Oceans, investments in 
advanced sonar detection technologies will surge.
 Partnerships and Joint Ventures: Companies like Lockheed Martin and 
ERAPSCO are collaborating to develop next-generation sonobuoys, integrating 
AI, IoT, and real-time data sharing capabilities.
