Market Dynamics:

Growth Drivers: Naval modernisation amid geopolitical tensions and growing commercial maritime applications sustaining sonar procurement

Geopolitical tension and advancements in naval modernization programs lead to investments in the naval market, as sonars are vital for performing such functions as submersible detection, minesweeping, and submarine tracking in the naval industry. Growth in naval market contracts, including the recently signed framework agreement between Kongsberg Naval Services and Norway’s Defence Material Agency concerning sonar services till 2040, reflects the long-term decades-long relationships underlying sonar market revenues not only in terms of purchasing but also in relation to maintenance and prolongation of service life.

Sonar technology finds application in the seabed charting, pipeline assessment, and monitoring of offshore wind parks and oil drilling facilities, thus generating further revenues for the sonar market along with military procurements due to the development of these industries. Sonar innovation is necessary for safe navigation, collision prevention, and effective fishing, while sonars are applied in oceanography, seabed mapping, archaeology, and biological research, contributing to commercial procurement diversity.

Restraints: High system costs and stringent military sonar regulations limiting broader commercial market penetration

The high cost of deploying sonar systems becomes an adoption obstacle especially in the commercial industry such as fishing and offshore exploration industries where there is a reduction in investments during economic downturns causing a drop in demand for the sonar systems in the said industries. In addition to this, market fluctuations can happen due to budgetary limitations in both commercial and military sonar markets where the latter faces less impact than the former considering that defense budgets come first before anything else.

The heavy regulation involved in the deployment of sonar systems, in particular, military sonar, together with the lack of awareness of the potential benefits of sonar systems by some industries hampers market growth opportunities. The tough conditions in which the sonar system operates become a factor of equipment failure giving rise to reliability issues that are being countered by alternative systems in the market.

Opportunities: Low-cost sonar development and AUV integration creating expanded commercial application opportunities

The development of affordable sonar systems and further utilization of sonar systems in various commercial industries, including fisheries and aquaculture, is likely to present growth potential in the market during the forecast period. Combining the usage of sonar systems together with other technologies used under the water will create a more complete understanding of the underwater environment, ensuring greater efficiency and safety in different tasks, while the main benefit provided by sonar devices is the ability to get information about distances to objects and their characteristics, which can be supplemented by high-resolution images collected by cameras or LiDAR.

It is possible to program AUVs to follow a particular route, which allows conducting underwater surveys, exploring underwater resources or measuring the depth of the water surface. One of the promising commercial areas in which the use of sonar and cameras will ensure a more accurate representation of the underwater environment through precise distance measurement and high-resolution images is the maintenance of subsea infrastructure.
