Silvus SC4400E joins Blue UAS Framework and Green UAS list

Silvus Technologies, a Motorola Solutions company, has the StreamCaster 4400 Enhanced (SC4400E) MANET radio added to the Defense Innovation Unit's Blue UAS Framework. AUVSI also lists the NDAA-compliant radio among its Green UAS Cleared Components.

The Defense Innovation Unit (DIU), part of the U.S. Department of Defense, adds the SC4400E to the Blue UAS Framework, which tests and certifies technology for military unmanned aircraft operations. The industry group AUVSI separately places the radio on its Green UAS list, attesting that it meets cybersecurity and supply-chain requirements for commercial drones and parts. Silvus announces the news from Chicago on December 9, 2025.

The SC4400E is powered by the proprietary Mobile Networked MIMO waveform of Silvus. Radios using it assemble a scalable mesh that connects hundreds of nodes, drones and ground radios alike, and carry high-bandwidth video, voice and sensor feeds back to command across long distances. The company designs the radio for fixed infrastructure, vehicles, maritime platforms, aircraft and unmanned systems, so missions on land, at sea and in the air can use it.

The radio also gives access to Spectrum Dominance 2.0, a growing suite of electronic-warfare defences. Advanced threat protection and anti-jamming sit alongside two stealth modes, Low Probability of Intercept and Low Probability of Detection. Silvus says the functions keep communications protected where spectrum is crowded and contested, and that performance holds even during an electromagnetic attack.

Neema Daneshvar, Silvus’ vice president of Product, says the two certifications confirm the radio meets the bar for secure connectivity in contested environments.

Why it matters

Three Silvus radios already carry both listings: the StreamCaster SC4200EP and the LITE SL4200 and SL5200. The SC4400E becomes the fourth. As an NDAA-compliant product, it adds to the options open to U.S. military unmanned programmes. Blue UAS targets military use, while Green UAS clears components for commercial drones, so the two listings reach different buyers.

Silvus, based in Los Angeles, belongs to Motorola Solutions (NYSE: MSI). Defence, law enforcement and public safety agencies worldwide use its StreamCaster family. Daneshvar says the listings strengthen the company’s standing in secure, resilient command-and-control and mesh networking, which is Silvus’ own assessment.
