Which Indian Naval Ship (INS) was deployed on an overseas mission to the South East Asia and Southern Indian Ocean region?

Introduction / Context:
The Indian Navy regularly deploys its ships on overseas missions to strengthen maritime cooperation, participate in exercises and demonstrate presence in important sea lanes. One such deployment involved cruising through the South East Asia and Southern Indian Ocean region. This question checks familiarity with the names of Indian naval ships and awareness of such overseas deployments by asking which specific ship was involved in this mission.

Given Data / Assumptions:

• The mission involved South East Asia and the Southern Indian Ocean.
• The options list four Indian Naval Ships: INS Shivalik, INS Talwar, INS Sahyadri and INS Kamotra.
• We must identify which ship was deployed on that particular overseas mission.

Concept / Approach:
INS Sahyadri is a stealth multi role frigate of the Shivalik class and has been part of several important overseas deployments and naval exercises. News related to the deployment in the South East Asia and Southern Indian Ocean region specifically mentioned INS Sahyadri. While ships like INS Shivalik and INS Talwar are also significant, the question aligns most closely with reports that highlighted INS Sahyadri on such a mission.

Step-by-Step Solution:
Step 1: Recognise that India deploys large frontline warships on long range overseas missions. Step 2: Recall that INS Sahyadri, a Shivalik class stealth frigate, has been involved in visits and exercises in the Asia Pacific and Indian Ocean region. Step 3: Media coverage of deployments to South East Asia and the Southern Indian Ocean frequently mentioned INS Sahyadri as the participating ship. Step 4: Compare the options. INS Shivalik and INS Talwar are also important but were not the primary focus of the specific deployment described in this question. Step 5: INS Kamotra is a smaller vessel and less likely to be the main ship highlighted in such a long range overseas mission. Step 6: Conclude that INS Sahyadri is the most accurate answer.

Verification / Alternative check:
Verification can be done by remembering official press releases and images showing INS Sahyadri at foreign ports during goodwill visits and exercises in South East Asia. Its role as a modern stealth warship made it suitable for representing the Indian Navy on such missions. The repeated association of INS Sahyadri with these deployments confirms that it is the correct option.

Why Other Options Are Wrong:
INS Shivalik: Although part of the same class and capable of overseas missions, it was not the vessel specifically highlighted in the deployment described in this question.
INS Talwar: A Talwar class frigate that has served in various operations, but not the ship referenced in this particular context.
INS Kamotra: A smaller patrol vessel, not typically used as the primary ship in major overseas deployments across such wide regions.

Common Pitfalls:
Test takers often confuse ships of similar classes, such as Shivalik class frigates, and may choose INS Shivalik simply because the name of the class is familiar. Another error is to disregard the scale of the deployment; a long voyage over South East Asia and the Southern Indian Ocean is more likely to involve a modern mainline frigate like INS Sahyadri. Carefully linking the deployment description with known ship roles helps avoid these mistakes.

Final Answer:
The Indian Naval Ship deployed on an overseas mission to South East Asia and the Southern Indian Ocean region was INS Sahyadri.
