Submarines are vital assets which can conduct a vast array of missions including anti-surface and Anti-Submarine Warfare, Intelligence gathering, Mine laying, Land attacks, and Special forces/Clandestine operations. The Stealth characteristics of a Submarine and its ability to make use of the underwater environment to its advantage make it a strategic asset and a game changer in the maritime domain.
Conventional Submarines
A Conventional Submarine is propelled by diesel-electric engines on the surface and by electric motors powered by batteries whilst submerged. These batteries are charged by diesel generators. The air intake for the diesel generator is facilitated by the snorkel which exposes the snort mast when propelling close to the sea surface.
Conventional submarines are restricted in submerged endurance due to their battery capacity. Over the years, the improved efficiency of diesel engines, better batteries and power-conserving motors have attempted to limit the constraints and improved the indiscretion rate which is the total time the submarine is exposed vis-a-vis the total time it is dived in a 24-hour cycle.
The challenge to overcome limitations on endurance, speed and concealment has constantly driven innovation in submarine propulsion technologies to design a system which would not require external air to run the diesel generator which led to the development of Air Independent Propulsion (AIP). The replacement of traditional propellers with pump jet systems improved maneuverability and stealth characteristics.

NEW MANTRA FOR DISPUTE RESOLUTION
AMIT COWSHISH explains why the Ministry of Defence (MOD), which is one of the biggest spenders, needs to watch out for the latest mediation rules.
NEW WAVE TERRORISM IN JAMMU & KASHMIR
KARAN KHARB argues that Pakistan's continued use of proxy war tactics against India, particularly in Jammu and Kashmir, poses a severe threat to national security. He advocates for a shift from a reactive to a proactive approach in counter-terrorism efforts, emphasizing the need for a comprehensive review of military strategies and a coordinated national policy to address both external and internal security challenges effectively.
INDIAN NAVY'S PROJECT-751 - GERMAN TKMS LEADS SPANISH NAVANTIA AFTER FIELD TRIALS FOR AIP-SUBMARINE DEAL
German submarine-builder ThyssenKrupp (TKMS) and India's Mazagaon Dockyard Limited (MDL) have emerged as leaders in the Indian Navy's Project-751, which aims to build six submarines with Fuel Cell Air-Independent Propulsion (AIP) and Lithium-ion batteries. Following successful field trials, TKMS and MDL have gained an edge over competitors by demonstrating their proven AIP technology and advanced submarine design tailored to the Indian Navy's needs.
VIKSIT BHARAT FROM A DREAM TO REALITY
The article explores India's ascent as a global influencer, emphasising its strategic advancements in foreign policy, defence, and economic growth. It also highlights India's challenges in achieving sustainable development and strengthening internal security. Adopting a forward-looking approach, the article envisions India's rise as a major economic power and a key player in global stability, as outlined by LT. GEN. A.B. SHIVANE (RETD.).
WILL MODI APPLY THE LESSON LEARNT FROM KOREA IN UKRAINE?
Speculation around Prime Minister Narendra Modi's possible visit to Ukraine raises questions about India's role in mediating peace between Russia and Ukraine. Drawing from its experience during the Korean War, India may seek to leverage its strategic neutrality to foster dialogue in a conflict where China and Turkey have also shown interest, opines PRAKASH NANDA.
UGVS: THE NEXT DIMENSION OF WARFARE
With the rest of the world developing unmanned ground vehicles at a breakneck speed, it is time for India to join the bandwagon at the earliest.
SUPERSONIC DESTROYER
The BrahMos programme has filled a critical gap in the Indian armed forces' missile inventory and continues to attract strong export interest, writes ATUL CHANDRA.
POLICE MODERNISATION: AN URGENT NEED OF THE HOUR
India is facing many internal security threats, and it is time to reshape the strategic dynamics by modernising the police forces.
FUTURE FIGHTER
FIA 24 provided important insights into the Global Combat Air Programme, which will redefine the future of air combat, reports MIKE RAJKUMAR.
FILLING THE GAP
A new Medium Transport Aircraft is essential for the IAF, but it will have to compete with other pressing programmes fighting for limited budgetary resources, analyses ATUL CHANDRA.
