The Manik engine, developed by the Gas Turbine Research Establishment (GTRE), a part of India's Defence Research and Development Organisation (DRDO), is a small turbofan engine (STFE) specifically designed for use in cruise missiles. This engine represents a significant advancement in India's defence technology, particularly for long-range precision weaponry.

The Manik engine is a compact, high-performance turbofan capable of producing approximately 4.5 kN of thrust. It features advanced technologies such as a digital engine control system, advanced fuel control systems, and capabilities for mid-air starting using pyro devices. The design includes a wide chord fan and a mixed flow compressor, which enhance its performance and efficiency.

The development of the Manik engine is part of DRDO's initiative to achieve self-reliance in defence technology. Currently, it is manufactured by BrahMos Aerospace at a rate of 12 units per year, with plans to scale up production significantly to meet future demands for various missile platforms, including the Nirbhay cruise missile.

Recent Achievements

The Manik engine recently gained attention following its successful integration into the Long Range Land Attack Cruise Missile (LRLACM) during testing. This milestone not only validates the engine's capabilities but also reinforces India's position as a producer of advanced indigenous defence technologies. The successful test highlights several strategic advantages.

By utilizing an indigenous engine, India reduces its dependence on foreign technologies thus ensuring strategic autonomy, which is crucial given the current geopolitical climate. The successful integration of the Manik engine into the Long Range Land Attack Cruise Missile (LRLACM) demonstrates India's capability to produce advanced weapon systems domestically. This integration allows India to expand its missile inventory without relying on external technologies, which is crucial for maintaining operational readiness.

The use of the Manik engine offers a more cost-effective solution compared to importing foreign engines, allowing for greater investment in other domestic defence projects.

However, the standard Nirbhay subsonic cruise missile is powered by a Russian NPO Saturn 36MT turbofan engine.

Future Prospects

Looking ahead, the Manik engine has the potential for adaptation across various missile platforms, including short-range ballistic missiles and air-launched cruise missiles. This versatility could position it as a cornerstone of India's missile development programs, enhancing national defence capabilities significantly.

The Manik engine represents a pivotal development in India's defence sector, showcasing advancements in indigenous technology while contributing to strategic autonomy and cost efficiency in military operations.
