Submarines are the most powerful vessel for performing underwater stealth operations such as anti-submarine warfare. During such secretive activities, submarines need to be silent in order to remain undetected from the enemy forces. Propulsion system plays an extremely important role in the functioning of a submarine for the completion of its desired operations. Majorly nuclear submarines are used due to their capability of performing extended operations. These propulsion system equipped submarines are expensive and generate a high level of noise which becomes a major threat. Therefore, diesel-electric submarines are used by several countries as they are silent and suitable for performing activities in littoral surfaces. Diesel-electric submarines have to get back on the surface to get fresh oxygen in order to recharge their batteries through diesel engines. This exposes such conventional submarines to the enemy radars and increases the chances of getting attacked.
Enhancement in underwater endurance of non-nuclear submarines will be one of the major factors that will have a positive impact on the growth of the market. The engines of the submarine require contact with the surface atmosphere to intake fresh air and to vent out engine exhaust. An AIP system helps a submarine to recharge its batteries without the need to contact surface atmosphere. Due to this, the submarine's snorkeling frequencies reduce and its underwater endurance increases. Owing to such benefits for the implementation of submarine AIP systems by armed forces globally, will propel the market growth.
APAC is expected to be the major revenue contributor to the market by 2023. The region has a vast stretch of shared maritime waters which requires vessels with high endurance capabilities. So, procurement and modernization of vessels with high endurance like AIP-equipped submarines is being promoted by these countries.
