Fusion power startups find new partners in the defense world

Curated by Shubham · TechCapsules · Sep 13, 2026

AI-summarised brief · reviewed before publication

Fusion startups are increasingly partnering with the defense sector as climate‑tech funding slows. The trend harks back to the field’s Cold‑War origins, when researchers sought peaceful uses for thermonuclear science. Recent collaborations include laser‑fusion company Xcimer receiving investment from RTX Ventures to explore high‑energy lasers for weapons, and Pacific Fusion signing an MOU with the National Nuclear Security Administration to run high‑energy‑density experiments at a new New Mexico facility. Both firms aim to prove net‑positive power generation while supplying the military with compact, electricity‑driven laser systems that could replace costly missile interceptors against swarms of drones. These deals provide vital capital and a dual‑use roadmap for an industry still far from commercial electricity markets.

💡 Why It Matters

· Defense interest offers fusion startups a lucrative, immediate revenue stream that can sustain R&D while commercial grid deployment remains years away.

Pune-Based N3X Labs Flies Scaled WRATH Prototype as Autonomous Aerial Programme Moves…

Pune-based defence technology firm N3X Labs has successfully flown a scaled‑down prototype of its WRATH autonomous aerial platform, marking the transition from computer‑based design to physical hardware testing. The flight took place in Gandhinagar, Gujarat, where the demonstrator was later destroyed during the test, indicating the use of experimental hardware. WRATH is envisioned as a long‑endurance, vision‑based system capable of persistent surveillance and tactical missions in GNSS‑denied or contested electronic‑warfare environments. The platform relies on terrain‑referenced navigation and a modular payload architecture to support reconnaissance, communications and sensing roles. N3X’s internal Redoubt Alpha autonomy suite, originally a separate product, now underpins WRATH’s AI validation and digital‑twin simulations, linking software development with real‑world flight data for future operational deployment trials.

💡 Demonstrating a flying prototype gives N3X concrete flight data to refine autonomous navigation in GPS‑denied zones, accelerating India's indigenous unmanned‑air capabilities.

DRDO develops indigenous GaN technology for next-gen radars, electronic warfare: Tiny 3.5×3…

The Defence Research and Development Organisation (DRDO) has successfully developed indigenous Gallium Nitride (GaN) technology, marking a significant milestone for India’s defense sector. According to a report from the Defence Ministry, this breakthrough enables the creation of next-generation radars and advanced electronic warfare systems. The core innovation is a compact Monolithic Microwave Integrated Circuit (MMIC) chip, measuring merely 3.5 by 3 millimeters. Despite its tiny size, the chip delivers up to 30 watts of power, demonstrating high efficiency and performance capabilities suitable for high-frequency applications. This development underscores India’s growing self-reliance in critical defense semiconductor technologies. By mastering GaN MMIC technology domestically, DRDO reduces dependence on foreign suppliers for essential electronic components. The initiative aligns with the broader "Make in India" mission, aiming to strengthen the nation’s strategic autonomy in defense manufacturing. The successful implementation of this indigenous technology ensures that future radar and electronic warfare systems will be powered by homegrown solutions, enhancing operational security and technological sovereignty for the Indian armed forces.

💡 Mastering GaN semiconductor fabrication eliminates critical supply chain vulnerabilities in India's defense electronics. This technological sovereignty ensures that sensitive radar and warfare systems remain secure from foreign dependency or potential export restrictions.

From cockpits to radar: 2 stocks building India’s defence electronics backbone

India’s aerospace and defence sectors are rapidly increasing their reliance on advanced electronics, creating a burgeoning market for domestic Electronics Manufacturing Services (EMS). The global aerospace‑defence EMS market, valued at about $81.8 billion in 2025, is projected to grow 5 % annually to 2033, while the broader EMS market could exceed $1.1 trillion by 2034. India’s EMS industry, estimated at $65 billion in 2025, is expected to triple to $197.8 billion by 2032, outpacing global growth. Government policies promoting indigenisation, higher domestic procurement, and the China + 1 supply‑chain shift are driving this expansion. Companies such as Cyient DLM are moving beyond simple PCB assembly to engineering‑led, build‑to‑spec production of cockpit avionics, flight‑control electronics, radar and electronic‑warfare systems, positioning themselves higher in the value chain.

💡 Indian EMS firms are poised to become critical suppliers for next‑generation defence platforms, reshaping global supply chains and reducing reliance on foreign manufacturers.

AI, jets, drones: IAI chairman Boaz Levy describes future battlefield, air force…

In a Reuters interview at the Singapore Airshow, Boaz Levy, chairman of Israel Aerospace Industries (IAI), outlined his vision for the next generation of air warfare. He said future air dominance will rely heavily on an integrated network of satellites, artificial intelligence, autonomous robots and advanced missiles, blurring the traditional distinction between front‑line and rear‑area operations. Levy highlighted IAI’s ongoing development of AI‑driven combat drones, swarming missile systems and satellite‑linked command platforms that can process battlefield data in real time. He also noted the company’s collaboration with the Israeli Air Force to test these technologies in joint exercises, emphasizing the shift toward a “distributed lethality” model where decision‑making and strike capabilities are dispersed across multiple unmanned assets.

💡 The shift to a sensor‑rich, AI‑controlled battlespace could redefine how nations project power, making speed and data integration the decisive factors in achieving air superiority.

Digantara Expands Bengaluru Space Hardware Capability With New Cleanroom

Bengaluru‑based Digantara has inaugurated a new cleanroom as part of its expanding space‑hardware infrastructure, a development highlighted during a September 9, 2026 visit by Anil Prakash, Director General of the Space Industry Association of India. While the facility’s size and cleanliness class remain undisclosed, the addition signals Digantara’s shift from pure research toward larger‑scale production of space‑qualified sensors and payloads. The company is concurrently advancing its second‑generation electro‑optical payload, originally designed for space‑domain awareness, for missile‑defence applications, having presented the system to Prime Minister Narendra Modi. Its indigenous PRISM sensor family, featuring a 48‑mm Double‑Gauss lens, has completed vibration and thermal‑vacuum qualification for PSLV and Falcon 9 launch environments, paving the way for faster manufacturing of additional payloads.

💡 The cleanroom enables Digantara to scale indigenous, high‑precision optics for both orbital surveillance and rapid‑response missile detection, reducing reliance on imported hardware and tightening India’s strategic sensor supply chain.

America Built the AI Engine. Our Enemies Are Using It Against Us.

A recent threat report from Anthropic reveals that state‑aligned actors in northern Yemen, China, Russia and Iran have been exploiting the company’s AI model Claude to accelerate weapons development. In Yemen, a cell used multiple Claude instances as virtual engineers, generating guidance, navigation and control software for a phone‑class guided rocket, a multi‑stage ballistic missile targeting a range of over 2,000 km, and a hypersonic glide vehicle variant. The AI was tasked to write code, conduct research, and review outputs, mimicking a small engineering team. Although Anthropic’s safeguards blocked many requests, the actors evaded detection by fragmenting queries and obscuring intent, enabling them to test‑fire a guided rocket that subsequently failed and was re‑examined with Claude. The report notes no confirmed operational deployment but highlights a new method of illicit AI‑driven weaponization.

💡 Adversaries are turning commercial AI into a low‑cost, on‑demand design lab, shortening the path from concept to prototype for advanced munitions. This shifts the security calculus from protecting hardware to policing the software tools that can be weaponized remotely.
