MARKET DYNAMICS

Market Driver

Critical Maritime Infrastructure Protection and Strategic Chokepoint Vulnerability Drives Market Growth

The Anti-Submarine Warfare (ASW) market growth comes from operational requirements regarding the need to defend vital sea routes and energy assets using sophisticated underwater threat detection systems. The Energy Information Agency of the U.S. reported that a total of 20 percent of world oil output about 20 million barrels a day is carried through the Strait of Hormuz, thus requiring this route to be a high priority concern in global energy security. Furthermore, there are estimated to be only 30 submarines in operation in the Indo-Pacific currently, but there are plans to have 250 in operation in Asian waters by 2030, thereby producing exponentially increasing demands related to detection and neutralization in maritime domain awareness.

Market Restraint

Acquisition Cost Escalation and Extended Procurement Timelines Hamper Market Growth

Market expansion is deterred due to constraint that exist in the current processes of acquisition in the defense sector. The cost analysis program on acquisition conducted by the Institute for Defense Analyses identified the cost growth phenomenon in major defense acquisition was above the 30 percent threshold. It also identified cases that spiked up to 70 percent increases in the cost of acquisition during the execution of the program. The Congressional Research Service analysis on the field of defense procurement identified the tendency toward contract extension of 5 years or more.

Market Opportunities

Unmanned Undersea Vehicle Proliferation and AI-Integrated Autonomous Operations Catalyze the Market Opportunities

The landscape of strategic opportunities is primarily driven by autonomous platform integration, which is increasingly becoming the reality with transition of naval forces' ASW systems of manned asset dependence to autonomous underwater vehicle networks. The success of the complete in-water test of the DARPA Manta Ray extra-large UUV carried out by Northrop Grumman in February-March 2024 showed the reality of gliding propulsion based on buoyancy, low-power hibernation modes with anchoring at the bottom of the sea, and mission management systems, allowing for autonomous underwater performance without the presence of human logistics. Contracts for the development of large underwater drones were award to Anduril Industries, Oceaneering International, and Kongsberg Discovery by the U.S. Defense Innovation Unit in the year 2025.

Market Challenges

Escalating Submarine Acoustic Stealth and Technological Arms Race in Acoustic Superiority Hinder Market Growth

The ASW market is facing challenge of competing against designs that have been developed to counter existing means of detection as a result of new submarine designs and operation concepts that specifically aim to counter existing means of detection by using innovative means of acoustic stealth. The Director of U.S. Navy Undersea Warfare and the Program Executive Officer of Submarines has vowed to retain an acoustic superiority advantage but has accepted that existing submarine nations are attaining acoustic stealth parity using electric propulsion systems and sound-reducing paint.
