Air Independent Propulsion Systems Market Analysis

ID: MRFR//1847-HCR | 111 Pages | Author: Swapnil Palwe| May 2024

The Air Independent Propulsion (AIP) Systems for Submarine market leads submarine propulsion innovation, improving covertness, endurance, and functionality. This market is heavily influenced by naval forces, technical advances, international considerations, and submarines' ability to operate secretly and autonomously.

Naval forces' goals shape the AIP Systems for Submarine market. Maritime forces worldwide want submarines with AIP systems to improve underwater endurance and functionality. AIP lets submarines work silently for longer periods without surfacing, which is important in surveillance, knowledge gathering, and clandestine missions. The importance of a covert, innovative submarine fleet promotes AIP system interest.

Submarine innovation redesign efforts are expected to boost the battle system industry as submarines' role in maritime warfare evolves. These projects are anomalies in the AIP systems industry. AIP technology may be adapted to older submarines by compressing frame space.

Mechanical innovations in AIP systems make the market distinctive. AIP allows submarines to function without surfaceing or snorkeling for air, boosting concealment. AIP developments such power gadgets, Stirling motors, and closed cycle diesel motors vary in durability, sound reduction, and productivity. Innovative submarine propulsion research ensures a steady stream of innovations, increasing competition among suppliers in this formidable sector.

International considerations shape AIP Systems for Submarine market aspects. As nations review their sea guard capacity, sending cutting-edge submarines with AIP systems becomes vital. The worldwide market influences acquisition decisions, driving AIP framework and submarine developers to compete. Maritime prominence and the need to counter emerging threats strengthen the market concept.

AIP systems are essential to modern submarine armadas because they allow submarines to operate covertly and independently. Submarines involved in social affairs, observation, and covert operations must work quietly. Compared to diesel-electric propulsion, AIP technologies allow submarines to stay below longer without compromising their covertness. This fundamental supports AIP systems and creates a distinct market climate.

AIP framework manufacturers' competition expands the market. Layout guard project workers and particular propulsion framework providers compete to provide AIP solutions that match global maritime forces' strict requirements. Naval forces consider framework productivity, coordination ease, maintenance needs, and compatibility with other submarine systems while choosing AIP systems. This competitive environment motivates companies to always enhance their products to stay ahead.

Air Independent Propulsion Systems (AIP) Market Scenario


Air Independent Propulsion Systems (AIP) Market Size Is Anticipated To Reach USD 180.01 Billion 2030, And At 5.01% CAGR 2020-2030


Air-independent propulsion (AIP) is the latest marine propulsion technology, which allows a submarine to operate without access to atmospheric oxygen. AIP is fitted or retrofitted on submarine hulls as an auxiliary source, with the diesel engine to handle surface propulsion. Earlier, diesel locomotive submarines had an underwater endurance for a few days and needed to travel back to surface for charging their batteries. As battery technology improved, the endurance of those submarines improved; however, it did not last for enough time. These batteries run out of charge in 4 to 5 days and need to be recharged. This is done by snorkeling, which exposes submarines to enemy radars, making them an easy target. Thus, the requirements of a system that may enable diesel-electric submarines to recharge their batteries without running their engines are increasing. AIP systems can allow them to continue sailing underwater and remain unseen. They are majorly used for enhancing the performance of small defensive submarines.


For instance, Siemens Industry Solutions Division signed an agreement with the Italian navy to provide two submarines with fuel cell technology for air-independent propulsion. The PEM fuel cell system takes charge of the power supply; hence, it will enable air-independent propulsion of submerged boats. Similarly, DRDO builds AIP propulsion systems that could be fitted in the Scorpene submarines under technology transfer from a French defense company, DCNS. The French company, DCNS, is also working on hydrogen fuel cell propelled AIP system for submarines.


Moreover, owing to the increasing importance of submarines in naval warfare, submarine technology upgrade programs are expected to drive the marketplace for combat systems, among others will be thought of because the indirect factors are driving the AIP systems market. AIP technology will be installed on existing older generation submarines by inserting a replacement hull section throughout a retrofit. The rise in popularity of new submarine technology is expected to drive the market during the forecast period. The factors responsible for the growth of air-independent propulsion systems for the submarine market are the need for extended submerged periods, cost efficiency, increased investment in R&D, and technological advancements in submarine systems.


Segmentation of the Global Submarine AIP Systems Market


Based on type, the global market has been segmented into stirling, MESMA, fuel cells, and others. The stirling segment accounted for the largest market share in 2018 and is expected to witness the highest CAGR during the forecast period, 2019 to 2025. In a stirling engine, the heat is produced in a combustion chamber that is separated from the actual engine. The whole system works in a closed system, thus forces the pistons in the engine to move and produce mechanical energy. They ensure low-power consuming operations and are much less noisy than the conventional diesel generators of submarines.


Based on fit, the global market has been divided into line-fit and retrofit. The line-fit segment accounted for the largest market share in 2018 and is expected to grow at a higher CAGR during the forecast period. The growing need for technology advancement in the shipbuilding and submarine building is expected to drive the segment growth during the forecast period.


Based on the region, the market has been categorized as North America, Europe, Asia-Pacific, the Middle East & Africa, and Latin America. North America is estimated to acquire the most significant market share in 2018. However, Asia-Pacific is expected to grow with the highest CAGR during the forecast period, 2019 to 2025. Technological advancements and increasing military expenditure by developing economies such as China and India are driving the Air Independent Propulsion Systems (AIP) Marketin the Asia-Pacific.
