Tomorrow, November 2, 2025, is set to mark an exhilarating journey as India's famed launch vehicle, the LVM3 rocket, embarks on its fifth mission. Dubbed as LVM3-M5, it will propel India’s heftiest communication satellite, CMS-03, into space. This satellite serves as a cornerstone for the Indian Navy, not only fortifying communication across maritime areas but also embedding the invaluable learnings from vital mission Operation Sindoor.
LVM3 stands as ISRO’s mighty launch tool, endowed with the full name Launch Vehicle Mark-3. Designed to transport voluminous payloads to space, this rocket has charted triumphant feats across four missions, notably the Chandrayaan-3 venture that saw India succeed with the first-ever lunar landing near the South Pole.

Preparations are at their peak for LVM3-M5. On October 26, 2025, the rocket was fastened with the satellite and taken to the launch pad, with final checks underway. The launch countdown is ticking down to 5:26 PM at Sriharikota’s Satish Dhawan Space Centre. Catch it live on ISRO's YouTube channel.
Formally dubbed Communication Satellite Mission-03, CMS-03 is a multi-band communication powerhouse, operating on diverse radio waves. Weighing around 4400 kilograms, it claims the title as India's heftiest communication satellite to reach the Geosynchronous Transfer Orbit (GTO)—an orbit facilitating easy transition to geostationary space, maintaining constant connection with Earth.

Designed to be operational for seven years, CMS-03 will span Indian mainland and vast maritime zones. With enhanced internet connectivity, video conferencing, and secure data transmission, it promises robust connectivity in remote areas, on ships, and aircraft. Outpacing its predecessors, it handles greater data flow swiftly.
Tailored primarily for the Indian Navy, CMS-03, also known as GSAT-7R, will bridge expansive maritime distances where signal strength wanes. Delivering fortified and seamless communication, it becomes the Indian Navy's vigilant 'Eye of the Ocean'.

Let's pivot to the narrative of Operation Sindoor, a pivotal Indian military endeavor from May 2025. Despite being a brief four-day operation, it unveiled India's military prowess.
A critical insight emerged: No scope for gaps in communication and surveillance. Immediate interconnection between the Air Force, Army, and Navy was indispensable. Coordinating maritime operations with the Air Force experienced slight delays due to older satellite systems.

In the wake of Operation Sindoor, the Indian government vowed to bolster military communication. A swift-paced $3 billion spy satellite project unfolded, integrating CMS-03. It promises to provide Naval Operations communication shielded from enemy jamming. In future scenarios akin to 'Operation Sindoor 2.0', the satellite will ensure fluid integration between the navy, air force, and army.
Undoubtedly, Operation Sindoor revealed the imperative for maritime communications, which CMS-03 aims to address, offering a digital shield that could become the key to victory in warfare.
On October 20, the integration of the satellite with the rocket concluded. Fast forward to October 26, it was readied on the launch pad. Currently, weather assessments, fuel loading, and final testing are underway with ISRO’s scientists working tirelessly. If all proceeds favorably, tomorrow will witness India's new luminary sparkle in the cosmos.
