The trilateral cooperation now includes advanced underwater drone systems and AI-powered maritime surveillance across the Indo-Pacific, aimed at countering increasing assertiveness from rival powers.

2. India Launches Indigenous Nuclear Submarine ‘INS Dhruv’

India’s naval strength surged with the commissioning of INS Dhruv, a domestically developed nuclear-powered ballistic missile submarine (SSBN). It marks a milestone in India’s strategic deterrence, bringing it closer to achieving credible second-strike capability.

3. China’s Navy Becomes the World’s Largest—Again

China continues its maritime expansion, now officially surpassing the U.S. Navy in total active vessels. With multiple Type 055 destroyers and new aircraft carriers entering service, the PLA Navy (PLAN) signals a direct challenge to Western maritime influence in the South China Sea and beyond.

4. US Navy Unveils AI-Crewed Ghost Fleet

The U.S. Navy has begun active deployment of its “Ghost Fleet”—a class of autonomous warships equipped with artificial intelligence. These vessels can operate with minimal human intervention, collecting data and performing reconnaissance with unmatched efficiency.

5. NATO Conducts Largest Naval Exercise Since the Cold War

Operation Steadfast Defender 2025, a massive NATO-led naval drill, involved over 60 ships from 20+ nations. Held in the North Atlantic, the exercise demonstrated alliance unity and rapid-response capability amid rising tensions with Russia over Arctic waters.

7. Green Navy Initiatives Gain Momentum

Sustainability has entered the defense dialogue. The British Royal Navy now deploys hybrid-electric propulsion ships and aims for carbon neutrality by 2040. Other nations, including Canada and the Netherlands, are piloting similar “green fleet” initiatives, blending maritime strength with environmental responsibility.

8. Iran’s Naval Presence in the Red Sea Triggers Global Response

Iranian warships crossing the Bab el-Mandeb Strait in early 2025 heightened global tensions. The U.S. Fifth Fleet and allied naval forces increased patrols, citing the need to ensure freedom of navigation in this vital trade corridor.

South Korea has broken new ground by launching the world’s first drone-exclusive aircraft carrier. The ROKS Haeil can deploy over 50 UAVs for reconnaissance, attack, and logistical operations, setting a precedent for future naval warfare.

10. The Arctic: New Frontier for Naval Supremacy

Climate change has opened new Arctic routes, sparking a silent scramble for dominance. Russia, Canada, the U.S., and Norway have all increased their naval presence in the region. New ice-capable vessels and bases are being established, as control over the Arctic becomes a geopolitical priority.

The Strategic Outlook for 2025
