India's second spaceport, being built at Kulasekarapattinam in Tamil Nadu's Thoothukudi district, mainly for SSLV launches to polar orbit and for private rockets.
ISRO is building the SSLV Launch Complex here mainly for polar launches of its Small Satellite Launch Vehicle. It will also serve rockets from private companies.
ISRO says the site lets small rockets fly a direct southward path. That increases how much they can carry to orbit.
Prime Minister Narendra Modi laid the foundation stone on 28 February 2024. That same afternoon, a Rohini RH-200 sounding rocket lifted off from a new pad on the site and reached about 75 km. It was the first launch from the new spaceport.
Construction of the main buildings began on 5 March 2025. On 27 August 2025, ISRO Chairman V. Narayanan laid the foundation for the launch pad itself. By then, work was under way on 32 of the complex's 33 major facilities.
In August 2025, ISRO said it aimed to finish the launch complex by the end of 2026, so that it can launch SSLV and rockets from private companies.
