DRDO's Indigenous Air-Launched Anti-Ship Missile

The question asks to identify India's first indigenous air-launched anti-ship missile developed by the Defence Research and Development Organisation (DRDO).

Understanding NASM-SR

The correct answer is the NASM-SR (Navel Anti-Ship Missile - Short Range).

• Developer: It was developed by the DRDO.
• Type: It is an anti-ship missile, designed to target enemy vessels.
• Launch Platform: It is an air-launched missile, meaning it can be fired from aircraft.
• Indigenous Status: It is recognized as India's first missile of this specific category developed domestically.
• Range: As the name suggests (SR for Short Range), it is intended for shorter distances compared to long-range variants.

Analysis of Other Options

Let's look at why the other options are not the primary answer:

• BrahMos: While a highly successful supersonic cruise missile developed jointly by India (DRDO) and Russia, and capable of anti-ship roles, it is not typically cited as India's *first indigenous* air-launched anti-ship missile in the same context as NASM-SR, especially considering NASM-SR's specific designation and development focus. BrahMos has multiple variants and launch platforms.
• Varunastra: This is a heavy weight torpedo, primarily designed for anti-submarine warfare, not an air-launched anti-ship missile.
• Astra: This is an air-to-air missile system, designed to engage enemy aircraft, not surface ships.

Therefore, the NASM-SR fits the description of India's first indigenous air-launched anti-ship missile developed by DRDO.
