India’s Defence Sector Faces 40-45% Skill Gap in Specialised Roles by 2030, Warns Report

India's defence manufacturing is booming (production at ₹1.78 lakh crore, exports up 62.66%), but a structural talent gap threatens growth. A Quess Corp report warns 40-45% of specialised roles (radar, avionics, quantum communications) could remain unfilled by 2030. The core issue: conventional engineering education lacks the systems-level thinking and field exposure needed for defence deployability.

Subsea Cables Carry 99% Internet Traffic: Vulnerabilities, Ownership Concentration & India's Resilience Plan

Subsea cables carry over 99% of global internet traffic, yet their supply chain is concentrated among a few private players and hyperscalers, making them vulnerable to sabotage, cyberattacks, and economic disruption. Recent NATO, Finland, and China incidents highlight intensifying threats, while India is building repair capacity via a DoT single-window clearance portal. This is a high-yield topic for GS3 infrastructure, science-tech, and security questions.

KAVACH Version 4.0 Commissioned on SCR: India’s Indigenous Automatic Train Protection System Explained

KAVACH, India's indigenous Automatic Train Protection (ATP) system, has been upgraded to Version 4.0 and commissioned on the South Central Railway's Malkajgiri–Kamareddi section over 108 route km. This is crucial for UPSC as it touches infrastructure, safety technology, and comparisons with global systems like ETCS, ATC, and PTC.

NavIC Constellation Drops to 3 Satellites, Fails to Provide Standalone Positioning: Govt Accepts

ISRO's NavIC system has lost its ability to provide independent navigation services because only 3 of its 7 satellites are operational, falling short of the minimum 4 required. The government has admitted this in Parliament, though timing services and emergency messaging continue. This raises concerns about India's space-based navigation self-reliance, but the armed forces mitigate risk by using NavIC as part of a multi-constellation GNSS that includes GPS, Galileo, and Glonass.
