In a significant milestone for India’s defense and maritime security, Hindustan Aeronautics Limited’s (HAL) Transport Aircraft Division in Kanpur has successfully completed the Mid-Life Upgrade (MLU) of 17 Dornier Do-228 aircraft operated by the Indian Coast Guard (ICG). Announced on May 18, 2025, this upgrade program has significantly enhanced the operational capabilities of the ICG, strengthening its ability to conduct maritime surveillance, search and rescue, and security operations across India’s vast coastline and exclusive economic zone (EEZ).
The upgraded Do-228 fleet is poised to play a pivotal role in safeguarding India’s maritime interests, aligning with the nation’s push for indigenous defense solutions and self-reliance.
Mid-Life Upgrade: A Transformative Overhaul
The Mid-Life Upgrade program for the ICG’s Do-228 aircraft involved a comprehensive modernization of avionics, sensors, and mission systems, tailored to meet the evolving demands of maritime operations. HAL’s Kanpur Division, a key hub for the production and maintenance of Do-228 aircraft, executed the upgrades with precision, ensuring that the aircraft remain operationally relevant for years to come.
Key enhancements include:
- Advanced Avionics Suite: The upgraded Do-228 aircraft are equipped with state-of-the-art glass cockpits, featuring multi-function displays (MFDs), digital autopilots, and enhanced navigation systems. These upgrades improve pilot situational awareness and reduce workload during complex missions.
- Modern Surveillance Sensors: The aircraft now feature advanced maritime patrol radars, electro-optical/infrared (EO/IR) sensors, and automatic identification systems (AIS). These systems enable real-time detection, tracking, and identification of vessels, significantly enhancing the ICG’s surveillance capabilities over India’s 7,516-km coastline and 2.01 million sq km EEZ.
- Improved Mission Systems: The integration of upgraded communication systems, including satellite communication (SATCOM) and secure data links, ensures seamless coordination with ICG ships, shore stations, and other agencies. The aircraft are also equipped with enhanced search and rescue (SAR) equipment, bolstering their ability to respond to distress calls at sea.
- Enhanced Performance: Structural and engine optimizations have improved the aircraft’s endurance, range, and reliability, enabling longer missions in challenging maritime environments.
These upgrades transform the Do-228 into a versatile, multi-role platform capable of conducting maritime patrol, pollution monitoring, anti-piracy operations, and humanitarian missions with greater efficiency.
The upgraded Do-228 fleet significantly enhances the ICG’s ability to secure India’s maritime domain, which faces threats such as illegal fishing, smuggling, piracy, and potential incursions in strategic waters. The advanced radar and EO/IR sensors enable the ICG to monitor vast areas of the Arabian Sea, Bay of Bengal, and Andaman and Nicobar Islands, ensuring early detection of suspicious activities. The aircraft’s ability to operate in adverse weather conditions and low-visibility scenarios further strengthens the ICG’s all-weather surveillance capabilities.
The upgraded fleet also plays a critical role in search and rescue operations, a core mandate of the ICG. With improved endurance and SAR equipment, the Do-228 aircraft can cover greater distances and respond swiftly to emergencies, such as distressed fishing vessels or natural disasters. The integration of AIS and SATCOM ensures real-time coordination with the ICG’s Regional Headquarters and the Maritime Rescue Coordination Centre (MRCC), enhancing mission effectiveness.
The upgraded Do-228 fleet is a force multiplier for the ICG, which operates in a dynamic and challenging maritime environment. India’s strategic location in the Indian Ocean Region (IOR), a critical hub for global trade and energy routes, necessitates robust maritime security. The enhanced surveillance and rapid-response capabilities of the Do-228 aircraft enable the ICG to assert India’s maritime sovereignty, deter illegal activities, and contribute to regional stability.
