ISRO’s LVM3-M5 successfully launches CMS-03, India’s heaviest communication satellite, boosting national space capability, maritime security and self-reliance.
The LVM3 (formerly GSLV Mk III) is the heavy-lift launch vehicle of the Indian Space Research Organisation (ISRO). With a three-stage design combining solid, liquid and cryogenic propulsion, LVM3 has established a stellar track record of seven consecutive successful missions. The LVM3 M5 flight, its fifth operational mission, aims to place the 4,410 kg multi-band communication satellite CMS‑03 into a Geosynchronous Transfer Orbit (GTO), marking a significant milestone in India’s space capability.
LVM3 M5 Launch
The LVM3 M5 Mission will launch from the Second Launch Pad at the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. Key mission highlights are given below:
Launch Date: November 2, 2025 at 17:26 IST
Payload: CMS-03, weighing ~4,410 kg, the heaviest communication satellite to be launched to GTO from Indian soil.
Vehicle: LVM3 M5, the fifth operational flight of LVM3 series.
Launch site: SLP at SDSC-SHAR (Satish Dhawan Space Centre in Sriharikota)
Flight sequence: ignition of strap-ons (S200), core (L110) ignition, strap-on separation, Payload Fairing (PLF) separation, L110 separation, C25 ignition, C25 shut-off, vehicle insertion and spacecraft separation.
Bahubali Rocket
The nickname “Bahubali Rocket” was affectionately given to ISRO’s LVM3 (Launch Vehicle Mark-3) by the public and media, inspired by the popular Indian film Baahubali, which symbolizes immense strength and power. The name reflects the rocket’s status as India’s most powerful and heavy-lift launcher, capable of carrying satellites weighing over 4,000 kg to geosynchronous orbit. Its successful missions, including Chandrayaan-2 and OneWeb, strengthened its image as India’s mighty “Bahubali” of space exploration.
LVM3 M5 Vehicle Details
The key details of the Launch Vehicle Mark 3 (LVM3) has been highlighted below:
Strap-On Stage: 2 × S200
Length: 26.22 m, Diameter: 3.2 m
Solid propellant (HTPB) approx. 204.5 t each.
Provide the massive thrust required for liftoff and early ascent.
Core Stage: L110
Length: 21.4 m, Diameter: 4.0 m
Liquid propellants (UH25 + N₂O₄) approx. 115.9 t.
Operates after strap-on burnout to continue the ascent.
Upper Stage: C25
Length: 13.5 m, Diameter: 4.0 m
Cryogenic propellants (LH₂ & LOX) approx. 28.6 t.
Final insertion stage into GTO; provides the precision required for the complex orbit.
LVM3 Rocket Features
LVM3 has established itself as India’s operational heavy-lift launch vehicle. ISRO lists its height at 43.5 m, payload fairing diameter at 5.0 m and lift-off mass around 640 t.
Designed capability to place ~4,000 kg into GTO and ~8,000 kg into Low Earth Orbit (LEO).
The LVM3-M2 mission carried 5,796 kg to LEO, showing the vehicle’s growing performance margin.
ISRO is working on a semi-cryogenic engine upgrade (SE-2000) to raise GTO payload from ~4 to ~5 tonnes and LEO to ~10 tonnes.
The vehicle stands 43.5 m tall and has a lift-off mass of 642 t.
The configurable stack is (2 × S200 strap-ons + L110 core + C25 cryogenic upper stage + 5 m Payload Fairing) and is designated “2S200+L110(HTVE)+C25+5 m OPLF”.
The mission’s target orbit is a GTO of apogee ~29,970 ± 3,700 km, perigee 170 ± 3.5 km, inclination 21.4° ± 0.1°, and argument of perigee 178° ± 0.3°, launch azimuth 107°.
Thus, LVM3 M5 is built on a solid foundation and positions India towards self-reliance in heavy-payload launches.
CMS-03 Satellite
CMS-03 (also referred to as GSAT-7R) is a multi-band communication satellite designed to serve a wide oceanic region including the Indian landmass. Weighing 4,410 kg, it is the heaviest communications satellite to be launched from Indian soil into GTO. The mission underscores ISRO’s capability to launch large communication satellites indigenously and reduces dependency on foreign launch services.
LVM3 M5 Launch Future Aspects
Looking ahead, the LVM3-M5 mission sets the precedent for:
Gaganyaan crewed mission (using human-rated version).
Large modules for India’s planned space station (BAS).
Enhanced commercial launches of heavy payloads into GTO and LEO.
Strengthened global market share for launch services. The technology upgrades underway (semi-cryogenic, higher thrust cryo, modular launchers) position ISRO well for the next decade.
LVM3 M5 Mission Marks Atmanirbhar Bharat Space
Earlier, India had to rely on foreign launch providers for heavy satellites over ~4 t to GTO, such as GSAT-11 (5,854 kg) and GSAT-20 (4,700 kg). With LVM3 M5 Launch undertaking the CMS-03 mission entirely with Indian hardware and infrastructure, it marks a shift towards self-reliance in heavy-lift capabilities. This boosts India’s autonomy in space access and strengthens its position in the global launch services market.
LVM3 M5 Launch Prime Minister on ‘X’
The Indian Space Research Organization’s LVM3 M5 Launch with the CMS‑03 satellite sparked widespread celebration on social platforms. Prime Minister Narendra Modi tweeted on the Social Platform – ‘X’ (formerly Twitter) his congratulations to ISRO, calling the mission a symbol of India’s scientific excellence and innovation.
#Bahubali, #LVM3M5, #AtmanirbharBharatSpace, and #IndiaInSpace trended across X, Instagram and Facebook, capturing global attention.
