DefenceAerospace – Andhra Pradesh Secures Key AMCA Fighter Aircraft Testing Facility
DefenceAerospace – Tamil Nadu has missed out on hosting the proposed Advanced Medium Combat Aircraft (AMCA) flight testing and integration centre after the Union government moved ahead with plans to establish the facility in Andhra Pradesh. The project is considered one of the most significant developments linked to India’s fifth-generation stealth fighter aircraft programme and is expected to strengthen the country’s defence aviation ecosystem.
Foundation Stone Laid in Andhra Pradesh
Defence Minister Rajnath Singh, along with Andhra Pradesh Chief Minister N. Chandrababu Naidu, recently laid the foundation stone for the proposed Rs 15,000-crore defence aerospace hub at Puttaparthi. The project is expected to serve as a major centre for testing, integration, and development activities associated with the AMCA programme.
The decision has drawn attention because Tamil Nadu had reportedly offered a technically stronger proposal for the project. Officials familiar with the matter said the state had spent nearly three years in discussions with the Defence Research and Development Organisation (DRDO) to bring the facility to Hosur.
Hosur Proposal Included Larger Runway Plan
According to officials involved in the discussions, the Tamil Nadu proposal was closely tied to the planned expansion of Hosur airport. The concept involved setting up the AMCA testing complex alongside the airport infrastructure, with the aviation testing facilities and passenger terminal positioned on opposite sides.
Sources stated that the Hosur plan included a proposed runway stretching about 3.5 kilometres, which was considered suitable for advanced fighter aircraft testing operations. In comparison, the existing runway at the Andhra Pradesh location was reportedly around 2.1 kilometres long.
Officials noted that Andhra Pradesh may need to acquire additional land to increase the runway length to nearly 3 kilometres to support the requirements of the defence project.
Concerns Over Aircraft Abort Testing Requirements
People aware of the technical discussions said one of the major considerations involved aircraft abort testing, a critical safety procedure conducted during the certification of new aircraft systems. During such tests, take-off procedures are intentionally halted to assess whether the aircraft can safely recover or stop under emergency conditions.
Industry experts point out that aircraft manufacturers and defence agencies worldwide rely on these tests before operational clearance is granted. Sources indicated that a runway of nearly 3.5 kilometres is generally preferred for such exercises, which strengthened Tamil Nadu’s argument in favour of the Hosur site.
Tamil Nadu Offered Land Support for Project
Officials said Tamil Nadu had also offered 100 acres of land free of cost as part of its proposal to attract the AMCA facility. The state government had reportedly agreed to meet several infrastructure requirements requested by DRDO.
Another factor that worked in favour of Hosur was its proximity to Bengaluru’s Vimanapura area, where the headquarters of the Aeronautical Development Agency (ADA) is located. ADA plays a central role in the design and development of India’s Light Combat Aircraft programme.
Sources stated that the distance between Hosur and the ADA headquarters is approximately 40 kilometres, which could have supported smoother coordination between research, testing, and operational teams.
Shift to Andhra Pradesh Raises Questions
Despite the advantages highlighted by Tamil Nadu officials, the project eventually moved to Andhra Pradesh after land was identified near the Sri Sathya Sai Central Trust area in Puttaparthi. So far, DRDO has not publicly explained the reasons behind the final site selection.
The development has also intensified discussions around competition among southern states to secure large-scale manufacturing and aerospace investments. Government officials pointed to earlier instances where proposed industrial investments initially planned for Tamil Nadu later shifted to Andhra Pradesh.
One example frequently cited is the investment proposal by South Korean footwear manufacturer Hwaseung Enterprises. The company had previously signed an agreement with Tamil Nadu for a large non-leather footwear manufacturing project before later deciding to establish operations in Andhra Pradesh’s Kuppam region.
Growing Focus on Defence Manufacturing Investments
The AMCA project is regarded as a strategically important initiative for India’s long-term defence preparedness and indigenous fighter aircraft ambitions. With increasing emphasis on domestic aerospace manufacturing, states across the country are actively competing to attract defence-linked infrastructure and high-value industrial projects.
Officials believe the establishment of the AMCA hub in Andhra Pradesh could significantly boost the state’s aerospace profile while also generating employment and industrial opportunities in the region. Meanwhile, questions continue to be raised about the factors that influenced the final decision despite the competing proposals placed before the Centre.
