India’s homegrown regional aviation initiative has reached a major milestone.
The National Aerospace Laboratories (NAL) has officially locked in the design for the Saras Mk2, a 19-seat light transport plane built to enhance domestic air travel.
With the blueprints now finalised, the Council of Scientific and Industrial Research (CSIR)-NAL is directing its efforts toward building the first prototypes and securing production partners for full-scale assembly.
As one of the most prominent civil aviation projects in the country, the CSIR-backed Saras Mk2 is tailored for operations at short runways and remote airstrips.
The aircraft aims to boost the government’s regional connectivity goals by taking on routes that simply do not make financial sense for larger commercial turboprops or jets.
Mohan Naik C, Chief Scientist at CSIR-NAL, recently affirmed that the engineering layout is completely frozen.
He noted that the laboratory is now deeply invested in prototype fabrication while actively negotiating with private and public industry players to handle large-scale assembly and system integration.
Constructing a modern aircraft requires a sophisticated blend of materials.
While CSIR-NAL boasts robust internal capabilities for fabricating the advanced composite materials that make up much of the airframe, it requires external assistance for the metallic components.
Consequently, establishing collaborations with industrial partners equipped for metallic fabrication has become a priority for the aircraft's structural completion.
The manufacturing process relies heavily on integrating these metallic and composite sections smoothly.
Because NAL’s in-house division is perfectly equipped to produce the composite structures, the next logical step for the programme is securing specialized defence and aerospace partners—such as Hindustan Aeronautics Limited (HAL)—to deliver the essential metallic airframe parts.
Prior to finalising the blueprints, the Saras Mk2 cleared a series of rigorous developmental hurdles.
Engineers successfully conducted extensive wind tunnel evaluations and validated the core onboard systems.
These essential tests assured the development team of the plane's aerodynamic stability and internal architecture before greenlighting the manufacturing phase.
The 19-passenger configuration perfectly addresses a specific gap in India’s aviation market.
By serving underserved locations where passenger traffic is too low for larger regional aircraft, the Saras Mk2 promises to expand domestic flight networks while curbing the need for imported foreign aircraft in this weight class.
Furthermore, the progression to physical manufacturing will stimulate India’s broader aviation ecosystem.
As prototype development accelerates, a surge in participation from domestic industries is anticipated for component production, system integration, and eventual serial manufacturing once the aircraft is cleared for commercial service.
Beyond passenger transport, this project stands as a powerful demonstration of India’s growing self-reliance in civil aerospace engineering, composite manufacturing, and complex avionics integration—domains heavily dominated by international aerospace giants.
Taking this aircraft from the drawing board to its anticipated certification will mark a historic achievement for the nation's civil aviation and defence manufacturing base.
Advanced Specifications and Future Timeline
Based on current programme developments and open-source data, the upgraded Saras Mk2 features several modern aviation advancements over its initial iterations:- Upgraded Powerplant: The aircraft will be powered by two 1,200 hp Pratt & Whitney Canada PT6A-67A turboprop engines.
- Modern Cockpit: It will feature a pressurised cabin, full digital avionics, a modern glass cockpit, and autopilot capabilities.
- Flight Controls: The aircraft integrates command-by-wire flight controls, significantly reducing weight and drag.
- Production and Testing: CSIR-NAL plans to build two prototypes to speed up the testing and certification process. The maiden test flight of the Saras Mk2 is currently targeted for December 2027.
- Military Interest: While designed primarily for civil regional connectivity, the Indian Air Force (IAF) has expressed strong interest in the platform, projecting an initial requirement for at least 15 aircraft once trials are successfully completed.
