India’s Space Breakthrough: ISRO Conducts Satellite ‘Dogfight’ After US-China Tensions

 ISRO executes advanced satellite manoeuvres resembling aerial dogfights using leftover SPADEX mission fuel. Two satellites (SDX 01 & 02) coordinated at 28,800 km/h—28x faster than a passenger jet.

• The SPADEX mission (launched to test autonomous docking) left 50% fuel unused due to precise execution.
• ISRO repurposed this fuel for an unplanned orbital combat simulation—a first for India.
• The SDX 01 and SDX 02 satellites performed high-speed maneuvers at 28,800 km/h, showcasing:
  • Close-proximity operations
  • Rapid repositioning

• Potential anti-satellite (ASAT) applications

Global Context: US vs China Space Rivalry

In March 2025, the US Space Force warned about China’s satellite dogfighting tests. US General Michael A. Guetlein stated:
“China is practicing on-orbit combat tactics between satellites—what we call space dogfights.” India’s test signals its growing counter-space capabilities, joining the US and China in advanced orbital warfare tech.

Why This Matters?

• Strategic Deterrence: Proves India can defend its satellites against hostile actions.
• Fuel Efficiency: Highlights ISRO’s ability to repurpose mission resources creatively.
• Space Militarization: Positions India as a key player in evolving space security dynamics.
