Singapore Defense Tech Hackathon

Co-organized with NUS Enterprise and TUM Venture Labs
Time to Accelerate Global Defense Innovation:
Join 120+ of the world’s most driven engineers, founders, and operators at the Singapore Defense Tech Hackathon (SDTH) on September 25–27, 2026.
This isn’t a typical hackathon. It’s a premier global launchpad for defense technology. Work alongside international talent, defense innovators, and industry leaders to tackle real-world security challenges together.
Meet potential co-founders. Build something that actually matters.
Our Mission
Readying the Little Red Dome -
The future of attritable aerial salvos will overwhelm traditional, sequential air defense systems. Revamp these legacy systems with the next generation of technology: With agentic AI, physics & digital twins at its core, compose robust defense products with commercially available technology. Build a new, comprehensive and investable idea that will secure safer skies. Getting sensors, C2, and shooters right is only half the battle. The other half is manufacturing and sustaining low-cost interceptors locally, without being held hostage by export controls or distant logistics chains. Agentic AI, next-generation perception, and additive manufacturing are three parts of the same answer.
Main Category: 2-day Challenge
2-day challenge tracks will be revealed to all registered participants one week before the event. Apply as a Hacker.
Focus Areas
Autonomous Command & Control (C2)
AI & Agentic Systems
Sensor-to-Shooter Integration
Counter-UAS & Drone Swarms
Maritime Security & Littoral Defense
Electronic Warfare (EW)
Resilient Communications
Space-Based Infrastructure & Defense
Modular, Integrated Defense Systems
“Defense Dome” architectures for city-scale protection
By Invitation Only: 3-Month Extended Challenge
A small number of applicants will be personally invited to take on a 3-Month Extended Challenge - an exclusive track for teams ready to work on problems a weekend cannot contain. Harder, more consequential, and deliberately ambitious. 3-months to work on three open questions to build on our mission, or the domain of your choice, at the frontier of defense technology:
Track A:
Can we build interceptors fast, cheap, and smart enough to match modern drone warfare, without skilled pilots or expensive supply chains?
Track B:
Can we design a sensing architecture that holds its picture when hundreds of threats arrive simultaneously?
Track C:
Can we keep meaningful human judgment in the loop when autonomous warfare has already outrun human reaction time?
Track D:
Based on your work and interests, you may also work on deep-tech in the domain of your choice, as long as it is relevant to defense. Do tell us more about your prior experience when you apply as a Hacker.
Selected teams receive mentorship, a per-project budget, and upgraded prizes. Apply as a Hacker. We’ll be in touch.
(You may participate in both the 3-month & 2-day challenges!)
The Prizes:
Prizes worth up to $30,000, including a $12,000 top prize.
SDTH is Phase 1 of a 9-month incubation program through the NUS Defence Tech Venture Lab.
The strongest teams get incubated at NUS with milestone-based funding, mentorship, access to defence testbeds and expert and investor networks.
It is a direct pathway from first prototype to funded defense startup, with roots in Singapore, solving challenges that matter globally.
More details will be shared in June.
