Thanking you, Yours faithfully, For Sigma Advanced Systems Limited (Formerly Megasoft Limited) Krishna Chaitanya Sadhu Company Secretary & Compliance Officer Sigma Advanced Systems and Munitions India Limited Join Hands to Advance Indigenous Course-Correction Technology for 155 mm Artillery Ammunition Collaboration to build next-generation indigenous capabilities, strengthen domestic manufacturing and support critical Indian military programmes Hyderabad, 14th October 2026 Sigma Advanced Systems Limited today announced signing of an exclusive Memorandum of Understanding (MoU) with Munitions India Limited (MIL) for the integration, indigenous manufacturing and supply of its well established 155 mm artillery course correction fuzes (CCF), along with associated components, subsystems and technologies. The collaboration marks a significant step in Sigma’s efforts to advance its next-generation indigenous capabilities in precision-guided artillery ammunition, building on its existing defence programmes and engineering capabilities. The consortium also aims to support ongoing critical programmes of the Indian military through the development, integration and localisation of advanced defence technologies. The initiative brings together Sigma’s well proven Indian engineering and programme execution capabilities and indigenously developed technology, MIL’s established ammunition manufacturing infrastructure. It aligns with the Government of India’s Make in India and Atmanirbhar Bharat priorities, with an emphasis on developing domestic capabilities in strategically important defence technologies. Building Indigenous Next-Generation Artillery Capabilities Course correction technology enables artillery projectiles to make in-flight trajectory adjustments, helping improve accuracy and operational effectiveness. Developing indigenous capabilities in this segment represents an important opportunity to strengthen India’s defence technology ecosystem and reduce dependence on imported solutions. {image for representational purposes only} Through this collaboration, Sigma aims to facilitate technology transfer, qualification, local manufacturing and integration of advanced course correction solutions in India. The programme will leverage on the Course Correction Guidance Kit, a mature solution currently used by international customers, as part of the technology collaboration. For Sigma, the initiative extends its ambition to move further up the defence value chain, from precision engineering and sub-systems manufacturing towards the development and integration of advanced defence systems. It also creates a platform to combine international technology expertise with Indian manufacturing and engineering capabilities to address the evolving requirements of the Indian Armed Forces. “The collaboration with Munitions India Limited marks an important step in advancing indigenous precision-guided artillery capabilities in India. By bringing proven course correction guidance technology with MIL’s established ammunition manufacturing capabilities and Sigma’s engineering and programme execution strengths, we aim to build meaningful domestic capabilities in a strategically important defence segment. This initiative reflects our commitment to going beyond localisation towards developing a stronger indigenous defence manufacturing ecosystem, in line with the vision of Atmanirbhar Bharat. We see this collaboration as an opportunity to contribute to the evolving requirements of the Indian Armed Forces while strengthening India’s position as a centre for advanced defence manufacturing.” Said, Sunil Kalidindi, CEO, Sigma Advanced Systems Limited Supporting Critical Military Programmes The collaboration is aimed to create capabilities that can contribute to the requirements of India's defence establishment, including supply to ongoing critical military programmes.
