The internet was busy debating jantar Mantar & a quiet facility in India witnessed something straight out of science fiction. An engine fired up. But it did not hum & it did not roar like a normal jet.
It detonated. Continuous supersonic shockwaves raced around a circular chamber 1000s of times/sec, harnessing controlled explosions to generate thrust.
The startup D-Propulse just gave the world a sneak peek of their air-breathing Rotating Detonation Engine (RDE) with an integrated aerospike nozzle.
Every jet engine on a commercial airliner, every fighter jet & every rocket we have ever seen operates on deflagration. We mix fuel with air/oxygen, ignite it & it burns relatively slowly at subsonic speeds. It is effective, but humanity has pushed this tech to its absolute physical limits.
RDEs throw that century-old playbook into the fire. Instead of burning fuel smoothly, an RDE explodes it intentionally. A continuous detonation wave sweeps around an annular (ring-shaped) channel at supersonic speeds, reaching over 2000 m/s. This is called Pressure-Gain Combustion.
It extracts 15-25% more thermal efficiency out of the exact same amount of fuel. In the world of high-speed flight, a 25% jump in efficiency is a completely different league.
Why this Matters for India?
For decades, the narrative surrounding Indian engineering was tied to catching up on legacy systems, spending billions trying to replicate 1970s turbofan engine metallurgy/importing critical defense tech.
D-Propulse is proving that India does not need to play catch-up anymore.
By leapfrogging straight to Pressure-Gain Combustion, an Indian deep-tech startup, guided by veteran scientists & built by young engineers is standing on the frontlines alongside research labs in the US, Japan & China.
Imagine hypersonic cruise missiles, ultra-long-range combat drones & spaceplanes that do not need heavy, complex moving turbopumps to break speed records. That is the realm this technology unlocks.
The future does not belong to those who build better versions of old machines. It belongs to those who rewrite the physics of how machines work.
NUCLEAR FUEL PROGRAMME
✦ Department of Atomic Energy (DAE) is promoting the indigenous thorium-based technologies to ensure long-term energy security, and to achieve self-reliance in the nuclear fuel cycle.
✦ India has limited resources of uranium and vast reserves of thorium. To optimally utilise the limited uranium resources and exploiting the large thorium reserves for achieving long term energy security in a sustainable manner, DAE is pursuing Three Stage Nuclear Power Programme.
✦ The programme is based on closed fuel cycle, wherein the spent fuel from one stage is utilised for extracting the fissile material, to be used as fuel in the next stage.

The students are at top priority, educationally n security-wise, so they need not worry and have their parents worried for them. The Honorable Prime Minister has tweeted, and I am sure that he will take strict action against all those people who are responsible for this leak. So students, plz go back to your parents n homes.
Sonam, it's done, bro. Don't extend this. Keep the spirit for another day if there be a need, which I doubt, n eat something. If u want, will send u food from home.
#WATCH | DRDO has successfully conducted the maiden flight test of Long-Range Surface-to-Air Missile Kusha today from the APJ Abdul Kalam Island off the coast of Odisha.
Kusha missile system is capable of neutralising wide variety of aerial threats including fighter jets, missiles, UAVs and large enemy aircrafts within a wide range and altitude envelope.

Nothing is more important than the welfare and future of our youth!
We have decided to set up fast-track courts to ensure swift and stringent punishment for those involved in paper leaks. Have directed the concerned authorities and officials to take all necessary steps in this regard. This continues our series of steps for safeguarding the interests of students.
Those who try to harm the future of our youth will not be spared.
देश के युवाओं का हित और उनका भविष्य हमारी सर्वोच्च प्राथमिकता है।
पेपर लीक के सभी मामलों में दोषियों को जल्द से जल्द कठोर दंड देने के लिए, केस के त्वरित निस्तारण के लिए फास्ट ट्रैक कोर्ट्स का गठन किया जाएगा। इस संबंध में निर्देश दे दिए गए हैं कि संबंधित विभाग आवश्यक कार्रवाई सुनिश्चित करें।
विद्यार्थियों के हितों को सुरक्षित करने के लिए, सरकार द्वारा लिए जा रहे निर्णयों की श्रृंखला में ये एक महत्वपूर्ण कदम है।
युवाओं के भविष्य के साथ खिलवाड़ करने वाले किसी भी व्यक्ति को बख्शा नहीं जाएगा।
தலைநகரில் ஜனநாயகம் நசுக்கப்படுவது வன்மையாகக் கண்டிக்கத்தக்கது!
டெல்லியில் நடைபெற்ற இளைஞர்களின் அறவழிப் போராட்டத்துக்கு ஆதரவாகக் களமிறங்கிய மக்களவை எதிர்க்கட்சித் தலைவர் திரு. ராகுல் காந்தி அவர்கள் டெல்லி காவல்துறையால் இழுத்துச்செல்லப்பட்டும் குண்டுக்கட்டாகத் தூக்கிச் சென்றும் கைது செய்யப்பட்டது ஜனநாயக உரிமைகள் மீதான அப்பட்டமானத் தாக்குதலாகும். இது வன்மையாகக் கண்டிக்கத்தக்கது.
நீட் தேர்வு நடைமுறைபப்டுத்தப்பட்டது முதலே அதன் மீதான நம்பகத் தன்மை குறைவது மட்டுமல்லாமல், மாணவர்கள் மன உளைச்சலுக்கு உள்ளாகி தங்களின் எதிர்காலக் கனவு மிகப்பெரிய கேள்விக்குறியாவதும் தொடர்கிறது.
நீட் தேர்வால் ஒவ்வொரு ஆண்டும் மாணவர்கள் பாதிப்பிற்குள்ளாவது நின்றபாடில்லை. எனவே ஒன்றிய அரசு நீட் தேர்வை முழுவதுமாக ரத்து செய்ய வேண்டும் என்று வலியுறுத்துகிறோம்.
🚨 BIG BREAKING
India bought a RECORD $5.14 BILLION worth of Russian crude in June 2026, the HIGHEST monthly IMPORT ever.
— India's energy policy is decided in New Delhi, not Washington 🔥
🚨 Unmask the Lies
❌ Pakistan-based propaganda handles are falsely claiming that the Indian Army has been deployed in New Delhi and is using weapons against protesters leading to several deaths and injuries.
✅ FACT: The protests are being managed by Delhi Police and other designated law-enforcement units, including CAPFs and RAF personnel. There is no Army deployment to manage the protest.

🎯 Disinformation Pattern:
Footage of civilian protests + fabricated Army deployment + false allegations of armed action = propaganda intended to create panic and damage the reputation of the Indian Army.
⚠️ Check the facts before sharing the narrative.
