TARVYN is developing tethered aerial systems built around an enclosed-impeller architecture, keeping high-speed rotating components inside the airframe rather than exposed. The early-stage company has demonstrated controlled lift through more than 200 functional tests and 30-plus design iterations, and is now working toward a stabilized tethered platform for public-safety and critical-infrastructure operations. Its intended first configuration combines aerial lighting and observation with persistent power and a defined operating boundary.

DPI UAV SystemsWith a rotorcraft legacy of more than 75 years, DPI UAV Systems designs, builds, and tests tethered unmanned aerial systems for defense and commercial missions. Since 1992, the company has developed persistent airborne communications and surveillance platforms, including systems designed for U.S. Navy and U.S. Army operations. More than 20 SBIR contracts and testing in operationally relevant environments have shaped its mission-focused engineering and payload-integration work.334511ESSINGTON, PA
Lighthouse AvionicsBorn from a Hilliard police chief’s effort to bring Drone First Responder operations to Ohio, Lighthouse Avionics builds passive airspace-awareness systems for counter-drone security, remote towers, and beyond-visual-line-of-sight flights. Founded in 2021, the Hilliard company developed its VICTOR platform from early radar and computer-vision work into deployable optical detection systems, including a remote tower operating at Springfield-Beckley Municipal Airport. Its dual-use technology serves public safety and commercial drone operators alongside defense and critical-infrastructure missions.COLUMBUS, OH
TCOM, L.PTCOM, L.P. designs, manufactures, integrates, repairs, and sustains lighter-than-air aerostat and airship systems, aerospace structures, components, subassemblies, avionics, tethers, mooring stations, and ground support equipment. It serves defense, homeland security, aerospace, border and maritime security, critical infrastructure protection, disaster response, and commercial missions.COLUMBIA, MD
WheelTugWheelTug is developing in-wheel electric motors that let commercial aircraft taxi without using their jet engines or airport tugs. The company’s system is backed by letters of intent from more than 25 airlines representing over 2,000 aircraft, with final assembly and system kitting planned at its 37,000-square-foot WheelTug Works facility in Baltimore. Its engineering and quality plans have been accepted by the FAA as it advances toward certification and manufacturing approval.BALTIMORE, MD
