Amid warming bilateral ties, India and the United States have steadily built their defense relationship over 20 years. More recently, shared concern over China’s rise and projection of power has motivated a renewed focused on institutionalizing the relationship at the highest levels while building the connective tissue necessary to innovate and collaborate effectively in support of preserving a free and open Indo-Pacific region. Announced during Prime Minister Modi's 2023 visit to the United States, the India-U.S. Defense Accelerator Ecosystem, or INDUS-X, strives to enhance both countries’ defense technological capabilities to balance China in the Indo-Pacific. As U.S.-India ties continue to deepen, it may also gradually reduce India's reliance on Russian hardware.
INDUS-X aims to “expand the strategic technology partnership and defense industrial cooperation” by deepening commercial ties across U.S. and Indian defense industries. The effort seeks to meet India’s decades-long interest in defense technology cooperation with the United States while advancing the Pentagon’s aspiration for integrated deterrence by leveraging Indian defense capabilities, diversifying supply chains and fostering collaboration between the public and private enterprise of both countries.
While the significant growth in U.S.-India defense ties — bolstered by bipartisan support across five administrations — opened the door to major strategic realignment, expanded trust, and spurred a wave of defense cooperation initiatives, the early efforts toward co-development and co-production struggled to overcome commercial and bureaucratic headwinds. Nevertheless, these early initiatives helped make both countries’ defense ecosystems more legible to one another and laid the groundwork for today’s deepening collaboration.
More recently, a shared and acute threat assessment of an increasingly powerful and coercive China led both countries to re-energize cooperation to secure a free and open Indo-Pacific. The institutional evolution of new defense offices in both countries — the U.S. Defense Innovation Unit (DIU) and India’s Innovations for Defense Excellence (iDEX) — additionally brought resources and attention to critical and emerging technologies to help their respective militaries modernize at the speed of innovation.
A shared and acute threat assessment of an increasingly powerful and coercive China led both countries to re-energize cooperation to secure a free and open Indo-Pacific.
INDUS-X emerged from — and owes much of its success to — these growing strategic ties, mutual threat assessments and institutional evolutions. On the eve of the third INDUS-X summit, India and the U.S. have breakthroughs to celebrate and more to look forward to.
INDUS-X is comprised of three central mechanisms. First, the initiative addresses information asymmetries by plugging gaps on business opportunities and demystifying U.S. and Indian acquisition procedures for investors, policymakers and startups. Second, INDUS-X establishes cross-national, social and commercial networks to connect the right private investors or labs with startups or engineers. Finally, by connecting government to private enterprise, INDUS-X helps mitigate the regulatory friction associated with integrating defense knowledge, goods and services.
The types of collaborations have also diversified beyond venture capital to encompass a range of cooperative research and development agreements and industrial partnerships, and earlier ventures are beginning to thrive. Public sector collaborations like the jointly developed air-launched drone program have crossed several milestones including a demonstration at Eglin Air Force Base in Florida this June and another demonstration planned for an Indian military testing range later this year. The partnership between Microsoft and the Indian Space Research Organization launched in January 2023 is poised to support the next wave of Indian space startups. And a new accelerator launched by FedTech and Indusbridge Ventures seeks to support Indian dual-use tech companies’ entry the U.S. market.
Washington and New Delhi hold a shared view that India should be able to stand up to and deter China to preserve stability in its neighborhood. As INDUS-X moves past its launch phase, the byproducts of U.S.-India academic and commercial collaboration are starting to have meaningful effects on such national security challenges.
Some partnerships offer critical potential for improved maritime reconnaissance and domain awareness. General Atomics’ collaborations with Indian startups for new chip and sensor designs and for targeting algorithms will help India’s soon to be acquired MQ-9B predator drones work effectively with U.S. and partner maritime reconnaissance platforms to defend freedom of navigation in the Indian Ocean. As India strives for maritime security in its neighborhood, a partnership between Liquid Robotics and Sagar Defence promises to equip India with a long-endurance unmanned system to support maritime and underwater domain awareness.
Meanwhile, Skydio’s collaboration with India’s Aeroarc will help to compete with China’s dominance of the global drone market, where Chinese dominance is enabling the People’s Liberation Army (PLA) to harvest critical data and even pre-position cyber-attacks.
Looking forward, the planned tests this September of the Stryker infantry combat vehicle and Javelin anti-tank missile on the India-China border may result in a joint production deals that not only stimulate India’s ecosystem of defense technology and suppliers, but also enhances Indian defense capabilities to deter PLA aggression. Such initiatives may also help reduce India’s dependence on some Russian weapons, for example by eventually replacing its Soviet-origin BMP-2 vehicles and Konkur missiles.
Even INDUSWERX collaborations between U.S. university labs and Indian startups can enhance deterrence including a potential partnership to develop 5G technologies to equip the Indian Army with flexible, secure battlefield communications in the mountainous terrain of the disputed border with China.
The INDUS-X Summit coinciding with the beginning of the U.S. and India’s largest-ever joint military exercise in Rajasthan offers a powerful demonstration of the deepening bilateral defense collaboration. India has matched deepening defense technology cooperation with greater operational cooperation including burden sharing, integrated deterrence efforts, and politically and militarily balancing China, even outside its theater.
The INDUS-X Summit coinciding with the beginning of the U.S. and India’s largest-ever joint military exercise offers a powerful demonstration of the deepening bilateral defense collaboration.
First, India has taken on new burden-sharing responsibilities. In November 2023, India became a full member of the Combined Maritime Forces naval coalition, conducting joint constabulary operations focused on maritime security under a multinational command. India also supported the creation of the Indo-Pacific Partnership for Maritime Domain Awareness (IPMDA) under the Quad (Australia, India, Japan and the U.S.) to provide visibility on dark shipping such as trafficking, terrorism, sanctions evasions or other illicit activity. India is poised to operationalize the South Asia leg of IPMDA this fall by completing a contract with HE360 to bring remote radio frequency sensing to the region.
Meanwhile, the growing tempo and complexity of U.S.-India military exercises advances integrated deterrence in the Indo-Pacific. By our count, over the past two years the U.S. and India have averaged 16 exercises (including nine bilateral) per year—over a threefold increase since 2018. These include exercises with Quad countries such as the Malabar exercise and lesser-known annual anti-submarine warfare exercise, Sea Dragon, which India first joined in 2021. In March 2024, the U.S. and India returned to the tri-service Tiger Triumph. The U.S. is the only country other than Russia to conduct a tri-service exercise with India (Russia’s last was in December 2019). The Indian and U.S. air forces have also expanded exercises, with the U.S. Air Force also conducting the first bilateral exercise over Indian airspace that included a B-1 bomber in 2023 and then the Indian Air Force returning to the U.S. Red Flag exercise in June 2024 for the first time in eight years.
Finally, we see India balancing China, not only in its own neighborhood, but also in the Pacific. After Beijing’s aggressive military exercises following the U.S. Speaker Nancy Pelosi’s visit to Taiwan in 2022, India, for the first time, publicly criticized Beijing for “the militarization of the Taiwan Strait.” The next summer, reports surfaced that three former military service chiefs had all attended a Taiwan Foreign Ministry forum, and the Indian chief of defense staff had requested a study of Indian options in a Taiwan contingency.
India’s assertiveness has extended to the South China Sea. India conducted a joint naval exercise with the Association of Southeast Asian Nations in May 2023. That June, it revised its stance from neutrality to moving in favor of the 2016 Permanent Court of Arbitration ruling that backed the Philippines’ claims in its dispute versus China in the South China Sea. In May 2024, India sent a flotilla of three ships to make a port call to Manilla to bolster the U.S. ally amid increasing maritime tensions with China, just a month after the first delivery of Indian BrahMos missiles to the Philippines, which has not evaded China’s notice.
The U.S.-India defense technology partnership has developed from aspirations to institutions.
The U.S.-India defense technology partnership has developed from aspirations to institutions. India’s geopolitical contributions to a free and open Indo-Pacific have also grown more substantive, whether shouldering greater operational security burdens, accelerating the pace and scope of military exercises with the U.S., or standing up to Chinese coercion.
Going forward, INDUS-X’s durability and growth will depend on its institutionalization and achievements. The institutional foundations of INDUS-X appear to be sound as DIU and iDEX have taken ownership over the initiative, upgraded their memorandum of understanding, launched official webpages for INDUS-X, and released new framework for the INDUSWERX testing consortium.
What will further solidify and add substance to these commitments is if the pathfinder projects of INDUS-X result in wins. The more significant demonstration of trust is going beyond signed agreements to sourcing innovations from one another through this initiative.
The conclusion of the General Atomics sale of the MQ-9B that will source from several Indian companies for subsystems and sustainment, and from startups for sensors, and microchips, will provide a visible template for other prime defense contractors. As the industrial partnerships between Liquid Robotics and Sagar Defence, and between Skydio and Aeroarc start to secure orders and deliver products to customers, other companies are more likely to follow suit and pursue their own teaming agreements. Similarly, follow-on and cross-national procurements from joint challenge winners will demonstrate INDUS-X as a viable pipeline to operational utility and commercial success. Large acquisition plans can also be married with joint challenges like tethering co-production of the Stryker to joint challenges that source from Indian ecosystem to equip it with indigenous subsystems.
Both countries will need to create more tools and resources to facilitate scouting and showcasing talent and innovation within each others’ defense ecosystems. Previously proposed ideas like joint investment funds and talent flow through academic exchanges and fellowships are worth pursuing.
There is interest within the U.S. government in obtaining dedicated pools of funds to better pursue engagement, exploration, scouting and matchmaking at Indian academic institutions, labs and companies for new capabilities and innovations. These could reveal opportunities for research collaboration, co-development and testing, or procurement of commercial products (e.g., for domain awareness) off the shelf or as a service. The U.S. can also widen the door to Indian defense innovators by opening up more types of challenge competitions that may involve controlled unclassified information. This might facilitate more commercial handshakes by sending clear signals to industry that doing business with Indian defense providers is not only permitted but encouraged.
On the Indian side, there needs to be a more coordinated effort led by the government to bring Indian companies to the target-rich environments where they can showcase their innovations. Several U.S. companies have observed that they don’t have great visibility on who their potential partners might be in the emerging Indian defense ecosystem. Some Indian startups have noted the need to refine their product for markets beyond India. In particular, if Indian companies want to do more business in the U.S. market, it would be helpful for the Indian Ministry of Defence to identify and set up Indian pavilions at the top defense or dual-use mainstream expos in the U.S. that may include Sea Air Space, AUVSI, Emerging Technologies for Defense, and AUSA.
Coproducing defense capabilities will accompany coproducing security. With greater institutionalization, scouting, and showcasing, INDUS-X will be poised for many more years of breakthroughs and success.
