DRDO carries out salvo launch of Pralay missiles

• Pralay is an indigenously developed, solid-propellant, quasi-ballistic surface-to-surface missile built by DRDO for tactical strike roles [1][2].
• On 31 December 2025, DRDO carried out a salvo launch of two Pralay missiles from the same launcher off the Odisha coast, a key user-evaluation milestone [1].
• Relevant for UPSC as a recurring Science & Tech / Defence indigenisation current-affairs item and for testing knowledge of India's missile family (Agni, Prithvi, BrahMos, Pralay, Akash) [1][2].

2. Why in the News

• DRDO conducted a salvo launch of two Pralay missiles in quick succession from the same launcher at around 10:30 a.m. on Wednesday, 31 December 2025, off the Odisha coast, as part of user evaluation trials [1].
• Both missiles followed the intended trajectory and met all mission objectives, confirmed by tracking sensors of the Integrated Test Range (ITR), Chandipur; terminal events were validated via telemetry from ships near impact points [1].
• Raksha Mantri Rajnath Singh stated the successful salvo launch established the missile's reliability [1].

3. Background & Evolution

• Maiden launch of Pralay: conducted by DRDO as an indigenously developed new-generation surface-to-surface missile (per PIB release on its first test) [1].
• Second flight-test: DRDO conducted a second flight-test of the conventional surface-to-surface Pralay missile to validate repeatability [1].
• Subsequent two consecutive flight-tests were successfully conducted, followed by the salvo launch (two missiles, same launcher) on 31 December 2025 as part of user evaluation trials — a step preceding induction [1].
• Developed by Research Centre Imarat (RCI), Hyderabad, with other DRDO labs — Defence Research and Development Laboratory (DRDL), Advanced Systems Laboratory (ASL), Armament Research and Development Establishment (ARDE) — and production partners Bharat Dynamics Limited (BDL) and Bharat Electronics Limited (BEL) [1].

5. Multi-Dimensional Analysis

Strategic / Geopolitical

• Fills a tactical-strike gap for targeting radar sites, command posts, and advance airfields, useful in a short, high-intensity border conflict scenario [2].
• Enhances credible conventional deterrence without crossing the nuclear threshold, given it is a conventional-warhead system [1][2].

Scientific / Technological

• Demonstrates indigenous capability in quasi-ballistic missile design, MaRV technology, and multi-launcher salvo firing — a complex feat requiring precise sequencing and telemetry tracking [1][2].
• Salvo capability (multiple missiles, same launcher, quick succession) signals progress toward saturation-strike readiness [1].

Administrative

• Testing conducted through coordinated efforts of DRDO labs (RCI, DRDL, ASL, ARDE) and ITR Chandipur, illustrating DRDO's decentralized lab-based R&D model [1].
• Transition from developmental trials to user evaluation trials indicates movement toward Army induction [1].

Economic

• Involvement of DPSUs BDL and BEL as production partners supports domestic defence-manufacturing/"Atmanirbhar Bharat" ecosystem and import substitution [1].

6. Recent Developments (last 12–18 months)

• 31 December 2025: Salvo launch of two Pralay missiles from the same launcher off Odisha coast as part of user evaluation trials [1].
• Prior to this, DRDO conducted two consecutive flight-tests of Pralay to validate consistency ahead of user trials [1].
• Reported in national press (including The Hindu) on 1 January 2026, under International/Defence section [User-supplied source].

7. Prelims Hooks

• Pralay is a solid-propellant, quasi-ballistic missile, not a cruise missile [2].
• Developed primarily by Research Centre Imarat (RCI), Hyderabad [1].
• Range bracket: 150–500 km [2].
• Terminal speed: Mach 5–6 [2].
• CEP (accuracy): less than 10 metres [2].
• Uses MaRV (Manoeuvrable Re-entry Vehicle) technology for evasive trajectory changes [2].
• Launch platform: road-mobile canister launcher (12×12 Ashok Leyland chassis) [2].
• Warhead types include HEPF, Penetration-Cum-Blast (PCB), and Runway Denial Penetration Submunition (RDPS) [2].
• Production partners: Bharat Dynamics Limited (BDL) and Bharat Electronics Limited (BEL) [1].
• The December 2025 test was a salvo launch — two missiles from the same launcher — under user evaluation trials, not a maiden test [1].
• Test conducted off the Odisha coast, tracked by the Integrated Test Range (ITR), Chandipur [1].
• Terminal events validated via telemetry from ships near designated impact points [1].
• Nodal ministry: Ministry of Defence (via DRDO) [1].
• Pralay is meant to meet the Indian Army's tactical ballistic missile requirement [2].

8. Mains Relevance

• GS-III: Science and Technology — indigenization of technology and developing new technology; Awareness in space, defence and IT.
• GS-II (peripheral): India's neighbourhood/security policy linkages if discussed in strategic-deterrence context.
• Possible question stems: 1. "Discuss the significance of indigenous tactical ballistic missile systems like Pralay in strengthening India's conventional deterrence capability." (GS-III) 2. "Examine the role of DRDO's laboratory network and DPSUs like BDL and BEL in achieving self-reliance in missile technology." (GS-III) 3. "How does salvo-launch capability alter the operational doctrine of short-range tactical missile forces?" (GS-III)

• Atmanirbhar Bharat in Defence / Defence Production and Export Promotion Policy — policy context for indigenisation.

10. Common Errors / Trap Areas

• Confusing Pralay (quasi-ballistic, tactical, conventional) with Agni series (strategic, nuclear-capable, long-range).
• Assuming Pralay is a cruise missile — it is ballistic/quasi-ballistic, not a cruise missile like BrahMos/Nirbhay.
• Misattributing the developing lab — it is RCI Hyderabad, not DRDL alone or ISRO.
• Confusing "salvo launch" (multiple missiles fired from same/different launchers in quick succession) with a routine single "flight-test."
• Assuming the December 2025 test was the maiden launch — it was actually a later-stage user evaluation trial, following earlier developmental flight-tests.
