DRDO's indigenous PRALAY quasi-ballistic missile during a flight test.
NEW DELHI: India has successfully flight-tested its indigenously developed PRALAY quasi-ballistic missile off the Odisha coast, bringing the missile system closer to induction into the Indian Armed Forces.
The Defence Research and Development Organisation (DRDO) conducted the test at approximately 11:10 am on Thursday from Dr APJ Abdul Kalam Island, Odisha. The trial was part of the missile’s user evaluation process.
According to the Ministry of Defence, all test objectives were successfully achieved, as confirmed by data collected through various range instruments deployed by the Integrated Test Range (ITR), Chandipur.
The Defence Ministry stated that the successful trial had made the induction of the missile system into the armed forces imminent.
Defence Minister Rajnath Singh congratulated DRDO, the armed forces and industry partners on the successful test. He said the missile, equipped with advanced technologies, would further strengthen India’s technological capabilities and the operational preparedness of its military against emerging threats.
What is the PRALAY missile?
PRALAY is an indigenously developed, short-range, surface-to-surface quasi-ballistic missile designed to strike important military targets using conventional warheads.
Developed by DRDO, the missile is intended to provide the Indian Armed Forces with a mobile strike capability against high-value military installations and infrastructure.
Unlike nuclear-capable strategic missile systems, PRALAY is designed primarily for conventional battlefield operations. It can carry different types of conventional warheads, allowing it to engage various categories of military targets.
The missile has a reported operational range of approximately 150 to 500 kilometres. Its payload capacity is reported to be up to 1,000 kg, although the achievable range varies depending on the weight of the payload.

These figures are based on previously published technical information and defence reporting. They should not be interpreted as a complete specification sheet for the November 5 flight test, as the Ministry of Defence has not released detailed flight-performance data.
Why is PRALAY called a quasi-ballistic missile?
One of PRALAY’s most important features is its quasi-ballistic flight trajectory.
A conventional ballistic missile generally follows a curved trajectory after its powered flight. Its movement is relatively predictable, allowing radar systems to track its path and calculate where it is likely to travel.
A quasi-ballistic missile combines ballistic flight characteristics with the ability to manoeuvre during flight.
PRALAY is designed to fly along a lower, flatter trajectory than many conventional ballistic missiles and can make changes to its flight path, particularly during its later stages of flight.
This makes its trajectory less predictable and can complicate tracking and interception by enemy air-defence systems.
However, this does not mean that the missile is impossible to intercept. Its manoeuvrability is intended to make interception more challenging.
Propulsion and guidance systems
PRALAY uses solid-propellant rocket propulsion to generate the thrust required for flight.
Solid-fuel propulsion offers several operational advantages, including easier storage, transportation and launch preparation compared with liquid-fuel systems that require additional fuelling procedures.
The missile also incorporates an advanced navigation and guidance system to maintain its intended flight path and improve accuracy against designated targets.
According to technical information presented by DRDO and reported by Janes, PRALAY uses a ring laser gyroscope-based inertial navigation system and a millimetre-wave seeker for terminal guidance.
The inertial navigation system helps determine the missile’s position and movement during flight without continuously depending on external navigation signals.
During the terminal phase, the millimetre-wave seeker helps the missile identify and guide itself towards its designated target.
The missile has also been reported to use thrust-vector control technology to support flight manoeuvres. This allows changes in the direction of thrust, helping the missile adjust its trajectory.
Its combination of navigation, terminal guidance and manoeuvrability is intended to improve accuracy and make its flight path more difficult for opposing air-defence systems to predict.
How accurate is the PRALAY missile?
PRALAY has a reported Circular Error Probability (CEP) of less than 10 metres, according to technical information shared by DRDO at Aero India 2023 and reported by defence publication Janes.
CEP is a statistical measure used to describe the accuracy of a weapon. A CEP of 10 metres means that, under the specified test conditions, approximately half of the projectiles or missiles in a sufficiently large group would be expected to fall within a 10-metre radius of the intended target point.
This figure should not be confused with a guarantee that every missile will land within 10 metres of its target.
The reported accuracy makes PRALAY suitable for engaging military installations and other designated targets that require precision strikes.
What targets can PRALAY strike?
PRALAY is designed to engage high-value military targets using conventional warheads.
Its reported target categories include:
- Military airfields and runways
- Radar installations
- Command-and-control facilities
- Communication infrastructure
- Ammunition storage facilities
- Other strategically important military installations
The missile has been associated with different conventional warhead configurations, including high-explosive pre-formed fragmentation, penetration-cum-blast and runway-denial payloads.
A penetration-cum-blast warhead is designed to penetrate a structure before detonating, while runway-denial payloads are intended to damage airfield surfaces and disrupt aircraft operations.
These different configurations give the missile flexibility for different battlefield requirements.
Mobile launch system and operational flexibility
PRALAY is designed around a canister-based, road-mobile launch system.
Its missiles can be transported and launched from specialised military vehicles, allowing the system to be deployed at different locations.
According to DRDO technical details reported by Janes, a 12×12 launcher can carry two PRALAY missiles, while an 8×8 launcher configuration can carry one missile.
The twin-missile configuration allows the two missiles to be launched independently against the same or different targets.
The mobile launch arrangement also offers flexibility in deployment and reduces dependence on fixed launch installations.
Who developed PRALAY?
PRALAY has been indigenously developed by Research Centre Imarat (RCI), Hyderabad, along with other DRDO laboratories.
Bharat Dynamics Limited (BDL) is one of the development-cum-production partners and has produced the missile system.
The programme involved Indian defence research organisations, industrial partners and other domestic suppliers, supporting the development of indigenous capabilities in missile technology, propulsion, navigation and manufacturing.
The development of PRALAY is part of India’s broader effort to strengthen domestic defence production and reduce dependence on imported military systems.
PRALAY’s development journey: From 2015 to 2026
PRALAY has undergone several years of development and testing before reaching its current stage.
March 2015: The PRALAY development project was sanctioned.
December 22, 2021: DRDO conducted the missile’s maiden successful flight test from Dr APJ Abdul Kalam Island off the Odisha coast.
December 23, 2021: A second consecutive successful flight test was conducted, with the missile tested using a different payload and range configuration.
July 28–29, 2025: DRDO conducted two consecutive user evaluation trials to validate the missile’s performance at different ranges, including its maximum- and minimum-range capabilities.
December 31, 2025: DRDO successfully conducted a salvo launch involving two PRALAY missiles fired in quick succession from the same launcher. Both missiles met their designated flight objectives.
November 5, 2026: DRDO successfully conducted another flight test as part of user evaluation trials. The Ministry of Defence confirmed that all test objectives were achieved and stated that the missile’s induction had become imminent.
What does the latest test mean for India’s defence capabilities?
The latest successful trial represents an important stage in PRALAY’s development and evaluation process.
Unlike initial development trials, user evaluation trials are intended to assess whether a weapon system meets the operational requirements of the armed forces.
The successful completion of this trial brings the missile closer to induction, although the government has not announced a specific date for its entry into service.
Once inducted, PRALAY is expected to provide the Indian Army and Air Force with another option for conventional precision strikes against important military targets.
Its reported range of up to 500 kilometres, mobile launch platform, different conventional warhead configurations and manoeuvrable flight profile make it relevant to India’s tactical missile requirements.
The missile also represents progress in India’s indigenous defence development programme, particularly in advanced propulsion, navigation, guidance and missile manufacturing technologies.
With the latest user evaluation trial successfully completed, PRALAY has moved another step closer to becoming part of India’s conventional missile arsenal.
