🗞️ Why in News: The Defence Research and Development Organisation (DRDO) and the Indian Air Force (IAF) successfully conducted a flight test of the RudraM-II air-to-surface missile from a Sukhoi-30MKI (Su-30MKI) fighter aircraft over the Bay of Bengal on June 2, 2026. The missile was tested under extreme release conditions, validating guidance, navigation, control, and targeting — and struck its pre-designated target with precision.

What is an Anti-Radiation Missile?
An anti-radiation missile (ARM) is a missile designed to detect, track, and home in on enemy radar emissions — destroying radar installations, surface-to-air missile (SAM) systems, and other radio-frequency emitters. It is a key tool for SEAD (Suppression of Enemy Air Defences) operations.
- When enemy radar emits, the missile locks onto the signal and homes to the source.
- Destroying enemy radar degrades their ability to guide their own missiles or direct anti-aircraft fire.
- ARMs are therefore force multipliers for air campaigns.
The RudraM Family
| Variant | Range | Status |
|---|---|---|
| RudraM-I | ~150-200 km | Tested 2020; operational induction |
| RudraM-II | ~300 km | Successfully tested June 2, 2026 |
| RudraM-III | ~550 km (reported) | Under development |
- All launched from IAF platforms, primarily Su-30MKI.
- RudraM-I was India’s first domestic ARM; replaced the need to import Israeli Harpy/Harop.
Significance
- SEAD / DEAD capability — India can now suppress Chinese or Pakistani radar and SAM networks at longer ranges before its own aircraft or missiles enter adversary air-defended space.
- Aatmanirbhar Bharat — indigenous development reduces import dependence on Israeli or Western ARM systems.
- Su-30MKI integration — deepens the IAF’s largest platform as a multi-role strike asset.
- Escalation and deterrence — a 300 km ARM (launched from a standoff position) complicates adversary air-defence planning.
DRDO’s Defence Technology Ecosystem
- DRDO — under the Ministry of Defence; ~52 labs; ~30,000 employees; apex body for defence R&D.
- Self-Reliance Index — India’s defence import share has declined from ~70% to below 45%; target is to reverse the ratio.
