Interoperability

Meaning
Interoperability is the ability of two or more armed forces to work together smoothly. To do this, they need matching procedures (the same way of doing tasks), communications that connect, and equipment that fits together. Forces build it step by step through joint exercises, shared training and shared logistics (supplies, spares and repairs). It matters because forces that cannot talk or move together safely cannot help each other in a crisis, such as a rescue at sea or a security threat.
Example
In October 2026, the Indian Navy frigate INS Sahyadri sailed to Busan for an exercise with the Republic of Korea Navy. The stated aim was interoperability. In the harbour phase, crews visited each other's ships and swapped expert knowledge. In the sea phase, the two navies practised coordinated navigation, helicopter operations and joint manoeuvres with ROKS Munmu the Great.
Don't confuse with
- Military alliance: an alliance is a formal promise to defend each other. Interoperability is only a practical skill of working together. Two navies can build it without becoming allies.
- Jointness: jointness means one country's own army, navy and air force working as one team, as in India's integrated tri-service Andaman and Nicobar Command. Interoperability usually means forces from different countries working together.
