The article dives into the Army C5ISR Center’s Folded Lightweight Annular Telescope (FLAT). This is a compact, mirror-based optical system built for small UAS and Launched Effects payloads.
FLAT aims to deliver sharper long-range imagery and reduce per-sensor costs. It leans on reflective optics instead of pricey materials, trying to make the supply chain a bit more robust.
You’ll also find details on the program’s open architecture, field demo plans for 2026, and possible uses on the ground or even by individual soldiers.
What is FLAT?
FLAT stands for Folded Lightweight Annular Telescope. It’s a compact, mirror-based optical design made for small unmanned aerial systems and launched effects payloads.
With advanced reflective optics and precision mirror fabrication, FLAT tries to produce sharper images than most sensors out there. The design intentionally cuts down on rare-earth materials and other expensive parts, hoping to lower per-sensor costs and ease supply-chain headaches.
The architecture scales across different payload sizes, letting even small platforms carry long-range EO/IR capability. FLAT works across multiple wavebands and supports both cooled and uncooled thermal sensors, so it’s good for day, night, and whatever the weather throws at it.
On top of the hardware, the program pairs the sensor with aided target recognition algorithms. That’s supposed to help with search, cueing, and dodging threats in tough environments.
Government design rights let the C5ISR Center share the architecture with industry—think CRADAs, SBIR awards, and Manufacturing Technology efforts. This open approach is meant to reduce vendor risk and strengthen the defense industrial base. They’re planning field demos to see how it all holds up and to guide deployment.
Technical advantages
- Mirror-based optical design cuts down on rare-earth materials and other pricey bits, but still delivers sharp imagery.
- Folded annular architecture packs a compact footprint for small UAS and payloads.
- Multiband capability lets it sense across multiple wavebands for all sorts of environments.
- Handles both cooled and uncooled thermal sensors for reliable day/night, all-weather ISR.
- Integrated analytic software for aided target recognition boosts search, cueing, and threat avoidance.
Open collaboration and industrial base
The government keeps design rights, so it can collaborate with industry through CRADAs, SBIR awards, and Manufacturing Technology efforts. This open approach aims to cut vendor risk and strengthen the national defense industrial base. By sharing the architecture, the C5ISR Center hopes to speed up innovation while keeping things secure and interoperable across partners.
Timeline and deployment
They’ve scheduled initial small-form prototypes for field demos and operational experiments in 2026. The hardware will be packaged as gimbaled payloads for real-world testing.
The plan is to list the sensor suite on a UAS Marketplace that catalogs validated systems and components for defense and interagency users. Beyond unmanned platforms, the Center is pushing the FLAT concept for possible use on ground and soldier-borne systems, hoping to bring the optics tech into more mission sets.
Strategic importance for ISR and defense
FLAT’s focus on compact, scalable optics and hardware-software integration positions it to deliver high-performance long-range EO/IR on small platforms. This approach addresses real gaps in contested environments that haven’t gotten enough attention.
The program uses reflective optics and an open architecture to boost reliability and supply-chain resilience. It also makes it easier to quickly add advanced recognition algorithms, which is a big plus.
FLAT aims to modernize small-platform ISR with a clear eye on cost, interoperability, and adaptability. That’s especially important for military and interagency users who need flexible solutions.
With battlefields constantly changing, the FLAT effort brings together innovative optics, software-enabled intelligence, and a collaborative industrial ecosystem. The goal? Give smaller platforms capable, all-weather, day/night sensing to help maintain strategic awareness, even in tough airspaces.
