Killing the Hidden Killer

INS Mangrol strengthens India’s underwater defences as Chinese anti-submarine capabilities and Pakistan’s submarine fleet underscore the need for indigenous technology and coastal preparedness. The most dangerous threat to a warship is not always visible on the horizon. Lurking beneath the waves, a hostile submarine can threaten naval assets, disrupt maritime traffic and place critical infrastructure at risk without revealing its presence. For India, whose maritime interests stretch across the Arabian Sea, the Bay of Bengal and the wider Indian Ocean, countering this hidden threat is an operational necessity. The commissioning of INS Mangrol, the Indian Navy’s third Anti-Submarine Warfare Shallow Water Craft (ASW-SWC) built by Cochin Shipyard Limited (CSL), Kochi, represents another important step in strengthening this capability. At a time when China is expanding its naval reach and Pakistan continues to operate Chinese-origin submarines, India’s ability to detect, track and neutralise underwater threats assumes growing strategic significance. Complex Challenges Anti-submarine warfare (ASW) presents particular challenges in shallow coastal waters. Unlike the relatively predictable acoustic environment of the deep sea, littoral waters generate complex sound patterns through seabed reflections, shipping activity and varying water conditions. These factors can complicate the detection and classification of hostile submarines. Yet these are precisely the waters where threats can approach naval bases, strategic ports, commercial shipping lanes and offshore installations. Conventional frigates and destroyers, despite their formidable capabilities, cannot always operate with the same agility in confined, shallow-water environments. This is where the ASW-SWC programme assumes significance. Conceived as a replacement for the ageing Abhay-class corvettes, these vessels are designed to provide specialised anti-submarine protection in India’s coastal waters. Their induction strengthens a crucial layer of maritime defence between the open sea and the country’s vulnerable coastal approaches. INS Mangrol carries forward a distinguished naval tradition. Named after the historic port town of Mangrol in Gujarat’s Junagadh district, it also recalls the legacy of the erstwhile INS Mangrol (M85), an Agray-class minesweeper decommissioned in 2004. Designed for anti-submarine warfare, underwater surveillance and coastal patrol, its significance, however, extends beyond its relatively compact dimensions. The vessel combines specialised sensors, indigenous weapons and manoeuvrability suited to the demanding conditions of shallow waters. Its sensor suite includes the DRDO-developed Abhay hull-mounted sonar and advanced low-frequency active towed-array sonar capabilities tailored to the challenging acoustics of littoral environments. Together, these systems are intended to improve the detection and tracking of underwater contacts. The vessel’s armament includes indigenous anti-submarine rocket launchers and lightweight torpedoes, supported by remote-controlled gun mounts for other operational requirements. Its indigenous Maareech Advanced Torpedo Defence System adds another layer of protection, helping detect, classify and counter incoming torpedo threats through acoustic countermeasures and decoys. These characteristics are particularly valuable when operating close to shore, where time and space for tactical decisions can be severely limited. Its utility is not restricted to hunting submarines. The platform can also undertake low-intensity maritime operations, surveillance of coastal choke points, mine-related missions and search-and-rescue duties. Such versatility makes it a valuable asset in peacetime as well as during periods of heightened tension. Equally important is the programme’s contribution to self-reliance. With more than 80 per cent indigenous content understood to be incorporated in INS Mangrol, the vessel reflects the growing capabilities of Indian shipyards, defence laboratories and domestic manufacturers, including micro, small and medium enterprises. The programme also demonstrates how complex naval platforms can strengthen the wider domestic defence ecosystem. The broader ASW-SWC programme has already gained momentum with the induction of vessels including INS Arnala, INS Androth and INS Mahe. The remaining ships are scheduled for completion by June 2028. Once the programme matures, the Navy will possess a more comprehensive and modernised force for addressing underwater threats close to India’s shores. The China Threat India’s requirement for stronger anti-submarine capabilities must be viewed against the wider transformation of China’s People’s Liberation Army Navy (PLAN). Beijing has invested heavily in modern surface combatants, submarines, maritime surveillance systems and aviation platforms, with ASW forming an important component of its expanding naval capabilities. The Type 055 Renhai-class guided-missile destroyer illustrates this evolution. Equipped with a 112-cell vertical launch system, advanced multifunction radar and electronic warfare capabilities, the class is designed for complex, multi-domain naval operations. Its ability to operate with shipborne helicopters, including the Z-20F in the PLAN’s anti-submarine role, adds an important aerial dimension to maritime surveillance and submarine hunting. China has also pursued greater operational coordination with Russia. Joint naval exercises, including anti-submarine activities conducted by the two countries in October 2024, have highlighted their interest in improving interoperability and coordinated maritime operations. For India, the implications are clear. The challenge is not simply the number of submarines a potential adversary possesses, but the integration of sensors, aircraft, surface ships, weapons and information networks into a coordinated operational system. Pakistan’s acquisition and operation of Chinese-origin submarine platforms adds another dimension to India’s maritime security calculations. The possibility of hostile submarines operating near strategic ports, naval installations and offshore energy infrastructure demands sustained vigilance. The protection of assets such as the Bombay High oil and gas fields is especially important given their significance to national energy security. INS Mangrol is an important addition to India’s coastal anti-submarine shield, but a single platform cannot neutralise every underwater threat. Effective ASW depends on the integration of ships, maritime patrol aircraft, helicopters, surveillance networks, trained crews and reliable intelligence. Equally critical are continuous upgrades, realistic exercises and the ability to operate seamlessly across different maritime environments. Aatmanirbhar Bharat in naval defence must mean not merely assembling ships at home, but developing the technologies, industrial depth and operational expertise needed to maintain a decisive advantage. INS Mangrol represents progress in this demanding contest. Its real value will lie in the larger indigenous maritime-defence ecosystem it helps strengthen.

Artificial Intelligence or AI is revolutionising fertility treatments of the future. The inclusion of AI enhances the accuracy, efficiency, and objectivity of sperm selection, hence potentially improving fertility outcomes by leaps and bounds. Traditionally, sperm sorting through manual methods is subjective to judgments. Processes like centrifugation and swim-up methods are used to separate sperm based on motility and morphology. Although they are effective, they have their limitations, leading to human errors that affect the success rates of fertility treatment. For instance, studies have shown that traditional sperm sorting techniques can have variability in success rates, with reported live birth rates ranging between 15 per cent to 25 per cent per cycle depending on the method and quality of sperm. Hence the introduction of AI helps in maintaining consistency in evaluations of sperm, using the same data set for every sample which leads to better judgments.


Automation and Standardisation- Automation of sperm selection and also introduction of AI in the process have improved the results in ART. AI-assisted sperm selection improves the accuracy in choosing high-quality sperm for fertilisation purposes, and also, pregnancy and live birth rates might be improved. Technologies like Intracytoplasmic Morphologically Selected Sperm Injection along with AI ensure the chances of pregnancies increase by about 10-20 per cent compared to the standard procedures. AI and Automation will decrease time taken to analyze sperm and increase opportunities to select better sperm with DNA integrity for better development and higher success rates in embryo selection. These processes ensure that the sperm selection process follows consistent criteria, reducing variability in outcomes caused by human error.


Analysing Complex Data for Better Outcomes- AI plays a crucial in improving IVF outcomes by analysing complex data and providing tailored recommendations. AI-driven tools and models such as those on SpOvum.ai point towards an opportunity to optimise ovarian stimulation decisions by assessing patient characteristics and follicle growth patterns. A study revealed that the use of AI in IVF improved egg yield and reduced medication costs. AI enables fertility specialists to make data-driven choices, improving overall IVF success rates and streamlining treatment processes.


Reducing Human Error- AI models can continuously learn and refine their performance by being trained on newer data. This adaptability ensures the technology remains unbiased and up-to-date with the latest scientific insights into sperm quality and fertility success rates. Studies have shown that AI-driven sperm sorting can decrease human-related errors by up to 25 per cent, improving sperm selection quality in terms of morphology and motility.


Reduction of Sperm Damage- The new AI-driven sperm sorting techniques also include microfluidic systems that are known to exhibit several advantages over the most commonly used conventional method, which is centrifugation. Traditional centrifugation methods, such as density gradient centrifugation, also cause severe oxidative stress and DNA fragmentation of the sperm because of the very high mechanical forces involved. The AI-infused microfluidic sorting minimises this damage significantly by involving gentler processes that mimic the natural pathway of sperm selection. The studies show that the process of microfluidic sorting decreases DNA fragmentation in sperm, which gives improved opportunities for success for IVF. For example, DNA fragmentation is 20 percent lower in sperm sorted using microfluidic processes than in traditional processing methods.


AI is bound to play an increasingly definitive role in fertility treatments, which will improve the outcomes for couples experiencing infertility.
