SMPP Introduces Prahar-150: India's New Long‑Range Loitering Weapon

Overview of the Prahar-150

India’s defence industry has expanded its unmanned strike portfolio with the introduction of the Prahar-150, a long‑range loitering munition developed by SMPP Limited. The system is designed to loiter for extended periods, enabling saturation attacks against high‑value targets while maintaining precision. Unlike earlier variants, the Prahar-150 incorporates a larger airframe and refined aerodynamics to sustain flight endurance beyond typical loitering munitions.

Technical Specifications

| Length | Around 4.8 meters |

| Maximum Take‑off Weight | 120 kg |

| Endurance | Up to 6 hours loiter time |

| Payload Capacity | Up to 30 kg of high‑explosive warhead |

| Guidance | GPS/INS with optional data‑link for mid‑course updates |

| Launch Method | Catapult or rail‑launch from ground or airborne platforms |

The table outlines the key dimensions and performance metrics that define the Prahar-150’s operational envelope.

Operational Capabilities

The Prahar-150 can remain on station for several hours, providing persistent surveillance and the ability to strike multiple targets in a single sortie.

Its high‑mass, saturation‑oriented design allows it to carry a larger warhead than earlier SM‑20 and SM‑150 models, increasing lethal effect against clustered enemy assets.

The aircraft’s clean aerodynamic shape reduces drag, while its twin vertical tails enhance stability during high‑speed dash phases.

Mission planning software integrates waypoint scripting, enabling pre‑programmed routes that adapt to dynamic battlefield conditions.

Strategic Implications

By adding the Prahar-150 to its catalogue, SMPP Limited strengthens India’s beyond‑visual‑range strike capability, complementing existing loitering munitions and conventional cruise missiles.

The extended loiter time reduces the need for frequent relaunches, conserving resources and increasing sortie reliability.

Moreover, the system’s ability to coordinate with high‑value missiles suggests a layered approach to target suppression, where the munition can loiter, identify, and designate before a kinetic missile engages.

This development aligns with India’s broader push toward indigenous unmanned platforms, reinforcing strategic autonomy and deterrence.

Future Outlook and Integration Pathways

The Prahar-150 is slated for initial operational testing with the Indian Air Force’s Western Command, where it will be integrated onto MiG-29UPG fighter jets via a dedicated pylon. Parallel trials are planned with the Army’s artillery units, allowing the munition to be launched from mobile platforms in contested zones. Development teams are evaluating a turbofan propulsion option that could boost cruise speed to 850 km/h, extending the effective engagement envelope. Additionally, a modular warhead interface is under consideration, enabling rapid swap between high‑explosive, sub‑munitions, or electronic‑attack payloads. These enhancements aim to position the Prahar-150 as a versatile asset capable of both kinetic and non‑kinetic missions, supporting India’s multi‑domain warfare doctrine.

Technical Details (Additional)

Propulsion is provided by a small turbojet engine delivering approximately 12 kN of thrust, enabling a maximum speed of 750 km/h at sea level and a service ceiling near 9,000 meters. The aircraft’s fuel capacity supports the six‑hour endurance figure, with a reserve margin that allows for contingency loitering. Aerodynamic refinements, including winglets and a refined nose cone, reduce drag by an estimated 12 percent compared to earlier models, enhancing fuel efficiency and extending mission radius.

Conclusion

The Prahar-150 represents a significant step forward for India’s unmanned strike ecosystem, offering prolonged endurance, larger payload, and precise guidance for saturation missions. Its integration into operational forces is expected to enhance tactical flexibility and reinforce the nation’s defensive posture. As the platform moves from prototype to deployment, it will likely influence future procurement decisions across the Indian armed services. The launch marks a decisive move toward a more capable and resilient unmanned warfare framework.
