ISRO successfully conducted a static test of the improved third stage (SS3) of the Small Satellite Launch Vehicle (SSLV) on December 30, 2025, at the Satish Dhawan Space Centre in Sriharikota. This new version of the SS3 solid motor, featuring a lightweight carbon-epoxy motor case, enhances payload capacity by 90 kg and incorporates advanced design improvements for the igniter and nozzle system, thus increasing efficiency and robustness. The test recorded 233 parameters, confirming operational predictability, and aligns with India’s strategic goal of bolstering indigenous space capabilities and production capacity. The commissioning of new solid motor production facilities further underscores India’s commitment to advancing its aerospace sector and fostering self-reliance in defense and space technology.
