Hoverfly Technologies Secures $20 Million Funding Led by Leonardo DRS to Expand Tethered Drone Manufacturing and Defense Capabilities
Hoverfly Technologies, a Sanford, Florida–based leader in tethered unmanned aerial systems (UAS) designed for persistent aerial surveillance and communications, has secured a new funding round believed to total US $20 million, according to public filings. Notable participants in the financing include Leonardo DRS and Gaspar Global Ventures.
Hoverfly Technologies builds tether-powered drones that provide full-mission endurance by transmitting power and data via tether lines, enabling systems to remain aloft for hours or days—unlike battery-based drones which typically endure only minutes. The company’s technology is used for intelligence, surveillance and reconnaissance (ISR), communications-relay, counter-UAS and network-extension missions, particularly in contested or GPS-denied environments.
The fresh infusion of capital comes as the company accelerates its push to scale manufacturing, expand its product portfolio and serve increased demand from defense and security customers. Hoverfly has publicly noted significant orders from the U.S. Army, and has shipped hundreds of systems to date—including more than 500 tethered platforms—as part of its sustained growth trajectory.
In describing its business, Hoverfly emphasizes that its drones are vehicle- or vessel-mounted, rapidly deployable, payload-agnostic and able to operate while on-the-move, providing a persistent elevated node for communications, sensor payloads or counter-UAS operations. Because the systems leverage a tether for continuous power and data, they offer advantages in endurance, security (low RF signature) and reliability.
With the latest funding, the company plans to expand its manufacturing footprint to support higher production volumes, deepen its R&D efforts—particularly around the recently unveiled “NEXUS” network-extension system—and broaden its go-to-market efforts both in the United States and among allied international defense customers. The capital is expected to fund enhancements across payload integration, vehicle-mounting kits, autonomous control software and ruggedization for harsh environments.
Investor participation by Leonardo DRS underscores the strategic value of Hoverfly’s technology to major defense contractors, while Gaspar Global’s involvement signals venture-market confidence in tethered drone systems as a growth segment. While neither firm’s exact contribution has been publicly disclosed, their inclusion in the cap-table highlights privacy and national-security buyers’ backing.
Hoverfly’s rise comes amid heightened demand for unmanned systems, especially tethered drones, which offer continuous overhead coverage, network-extension capabilities and resilience in challenging operational conditions. The company asserts its systems have been deployed across multiple U.S. Army formations, mounted on combat vehicles, unmanned ground vehicles and naval vessels, delivering critical ISR and communications functionality in real-world missions.
However, the company faces several industry-specific headwinds. Scaling high-volume manufacturing of unmanned systems with complex payloads and ruggedized components is capital-intensive. Doctrinally, deploying tethered UAS at scale requires vehicle integration, logistics support, operator training and supply-chain readiness—for which contract-cycle timelines can be lengthy. Export-control and regulatory compliance also pose constraints for international sales of advanced unmanned systems.
Notwithstanding these challenges, Hoverfly’s market positioning—with a physically persistent aerial node that integrates power tether, data feed and payload mount—differentiates it from free-flying drones and heliborne systems. The company’s strategy of leveraging vehicle or vessel-mounted platforms enables operational flexibility and sustained airborne presence in both tactical and commercial settings.
With the newly announced funding, Hoverfly Technologies is positioned to advance from early-stage adoption into broader deployment. Its goal is to demonstrate systems at scale, move beyond prototype orders into production contracts, and expand its footprint both within domestic defense and overseas allied markets. As tethered UAS become more integral to modern force structure and persistent surveillance, Hoverfly appears to be capturing a meaningful share of this evolution.
