RudraM-II anti-radiation missile flight tested

DRDO and the IAF test India's next-generation air-launched radar-killer from an airborne platform.

What happened

• The Defence Research & Development Organisation (DRDO) and the Indian Air Force (IAF) carried out successful flight-tests of the RudraM-II air-to-surface missile from an airborne platform on 2 June 2026.
• The tests were run under extreme release conditions with a critical trajectory, validating the performance of all of the missile's subsystems after launch.
• After release the missiles were guided to a predefined target with pin-point accuracy, and every test objective was met.
• Flight data was captured by range instruments deployed by the Integrated Test Range (ITR), Chandipur, off the Odisha coast.
• RudraM-II was indigenously developed with Research Centre Imarat (RCI), Hyderabad as the nodal DRDO laboratory, supported by sister labs and a chain of public-sector and private industry partners.
• Defence Minister Rajnath Singh credited the trial with showing the "growing maturity" of indigenous defence technologies and a step toward Aatmanirbharta (self-reliance) in advanced weapon systems.
• The Secretary, Department of Defence R&D, and Chairman DRDO congratulated the teams across DRDO, the IAF, the DPSUs and the industry partners involved in the programme.

What a missile trial like this actually proves is narrower and more important than a headline suggests. A "flight-test under extreme release conditions" means the missile was dropped from the carrier aircraft at the edge of its tested envelope — demanding angles, speeds and trajectories — to confirm that the airframe separates cleanly from the jet, that the booster ignites, that the seeker acquires its target, and that the guidance and control surfaces fly the weapon to a designated aim-point. When the release reports that "all subsystems" performed and the missiles hit a predefined target with "pin-point accuracy," it is reporting that this full chain — separation, propulsion, seeker, guidance, terminal accuracy — held together end to end. That is the milestone that moves a missile from a developmental design toward a service-ready weapon.

For Prelims

• What it is: RudraM-II is an anti-radiation, air-to-surface missile (ASM) — a precision weapon designed to home in on and destroy enemy radars, surface-to-air missile (SAM) sites and electronic-warfare emitters.
• The mission, in doctrine: this role is called SEAD — Suppression of Enemy Air Defences. By knocking out an adversary's radar network, a SEAD weapon "opens a corridor" so that follow-on strike aircraft can operate without being tracked or engaged.
• How it finds the target: anti-radiation missiles carry a passive seeker that does not emit any signal of its own — it listens for the radio-frequency emissions of a hostile radar and rides that beam down to the source. RudraM-II is reported to add an Imaging Infra-Red (IIR) seeker for terminal precision, so it can still hit the target even if the radar is switched off mid-engagement.
• Class & generation: a tactical, supersonic, air-launched stand-off missile — the second member of India's "Rudram" family and the successor to RudraM-I, with a substantially longer reach (reported in the ~300+ km class, against roughly 150 km for RudraM-I).
• Carrier aircraft: the Rudram series is integrated on the IAF's Su-30 MKI heavy fighter, the standard launch platform for these stand-off weapons.
• Lead developer: Research Centre Imarat (RCI), Hyderabad — the DRDO laboratory specialising in missile guidance, avionics and seeker technology — acting as the nodal lab.
• Partner laboratories (source-anchored): Defence Research & Development Laboratory (DRDL), High Energy Materials Research Laboratory (HEMRL), Armament Research & Development Establishment (ARDE), and the Integrated Test Range (ITR), Chandipur.
• Production partners (DcPPs): Hindustan Aeronautics Limited (HAL), the Regional Centre for Military Airworthiness (RCMA), the Missile Systems Quality Assurance Agency (MSQAA) and a spread of Indian industry — a deliberate "development-cum-production" model that builds a manufacturing base alongside the design.
• Test range: ITR Chandipur, Odisha — the DRDO range that instruments and tracks most Indian missile trials.
• For UPSC: RudraM-II = indigenous anti-radiation (SEAD) air-to-surface missile by DRDO (RCI, Hyderabad), the successor to RudraM-I, India's first home-grown anti-radiation missile.
• What it is NOT: it is not a long-range strategic or ballistic missile (that lane is Agni/Prithvi), not an air-to-air missile (that is Astra), and not a surface-to-air interceptor (that is Akash/QRSAM). It is a tactical radar-suppression weapon launched from a fighter against ground targets.

The Rudram family — peer placement

RudraM-II is best understood as one rung on a deliberately tiered ladder of indigenous anti-radiation / ground-attack missiles. The programme began as the DRDO New Generation Anti-Radiation Missile (NGARM), later named RudraM-I, which was test-fired from the Su-30 MKI in October 2020 and gave India its first home-grown capability to destroy enemy radars — a class of weapon previously held only by a handful of advanced air forces. Each successive variant extends range and adds guidance options, so that one airframe family can cover everything from short tactical suppression to deep stand-off strike:

The doctrinal point is that anti-radiation missiles change the arithmetic of an air campaign. An air force cannot strike freely while the adversary's integrated air-defence (IAD) radars are live, because those radars cue the SAM batteries and interceptors that hunt incoming aircraft. A weapon that can be fired from a stand-off distance to silence those radars therefore acts as a force-multiplier for the entire strike package — which is why the SEAD mission is treated as one of the hardest and most valuable in modern air warfare. Internationally the reference points are weapons such as the American AGM-88 HARM and its AARGM successor, the kind of capability historically confined to a small set of advanced air forces; RudraM gives India a comparable, indigenously controlled radar-suppression capability rather than an imported one.

The progression across the family is also a lesson in how a modern weapon programme is built incrementally. RudraM-I proved the core hard problem — a working passive radio-frequency seeker that can detect and home on a hostile radar — on a relatively short-range airframe. RudraM-II then stretches the range into the ~300+ km class and reportedly layers an Imaging Infra-Red (IIR) seeker on top of the anti-radiation seeker, which matters tactically: a clever adversary will switch its radar off the instant it detects an incoming anti-radiation missile, hoping the weapon loses its target. A dual seeker defeats that tactic, because the IIR channel can carry the missile onto the target even after the radar goes silent. The later RudraM-III and the planned RudraM-IV push reach further still, toward deep stand-off strike. Each step reuses the proven base and adds one increment of capability — a model that reduces programme risk and steadily widens the IAF's options from a single missile lineage carried on one fighter.

Why "indigenous" carries weight here

The release frames the test around Aatmanirbharta — self-reliance — and for anti-radiation missiles that framing is more than rhetoric. SEAD weapons depend on extremely sensitive electronics: a passive radio-frequency seeker that can detect, classify and lock onto a specific hostile radar emission, plus the guidance and control to ride it to the source. These are technologies that exporting countries guard closely and rarely transfer with full source access, and which can be withheld at the moment of a conflict. Building the seeker, the guidance computer and the propulsion at home — through RCI and its sister laboratories, and then transitioning to Indian production partners under the development-cum-production model — means the IAF controls the supply chain, the upgrade path and the wartime availability of the weapon. That is the substantive content behind the slogan, and it is what makes a successful trial of an indigenous SEAD missile worth more than a routine procurement.
