On-the-Move Solutions

For next-generation combat vehicles, Hoverfly is an incredibly valuable asset. The tethered UAS’s Autonomous ISR provides the pilot with on-demand situational awareness and advanced targeting that can dramatically alter a mission. See beyond the tree line and adjust rounds with efficiency to shift the battle in your favor.

Additionally, Hoverfly systems are the perfect surveillance sentry for military base security and overwatch. With its rugged design, expeditious setup, and intuitive operation. Hoverfly tUAS is ready for deployment in all combat scenarios.

“My favorite weapon system was the Mark 19. Because of how, whenever we can launch the Hoverfly and also correct and adjust our rounds from the Hoverfly, it’s an all-in-one system right there. You don’t need a third person to tell you where and how to adjust your rounds; you can see it all for yourself from the system itself.”

– SPC Grabowski – Robotic Vehicle Operator (DEVCOM GVSC)

Human-Machine Integrated Formations (H-Mif)

The future of combat is in robotics. To keep humans out of harm’s way, our military has to be at the forefront of unmanned technology and integrated formations. Hoverfly is leading the charge in the development of tethered technology within H-MIF. For robotic combat vehicles, we’re the #1 fielded tethered-UAS. Our systems provide autonomous on-demand situational awareness that turns the tide of battle.

“1st Lieutenant stated, ‘Normally the Opposing Forces (“OPFOR”) are about 30% accurate for indirect fire missions, we were 100% successful with the geo-location on the Hoverfly.’ This was a game changer for them.”

– Hoverfly TeUAS on Project Origin vehicle at JRTC

“Overall – the robots and the Hoverfly really performed well, and the end result was that the NTC Commander wants the robots at NTC on a permanent basis – this would not have been the case if he was not pleased with the performance.”

Variable Height Antenna (VHA)

VHA is now a critical piece of infrastructure for the Integrated Tactical Network (ITN). With multiple payload configurations, Hoverfly can rapidly take a wide variety of radios to 200 feet and create an expanded and persistent communication bubble. By enhancing and extending the tactical network, Hoverfly VHA allows command and control to remain agile and connected – ensuring missing success.
