Ghost Sled reaches a disabled vehicle, extracts it, and gets the crew out — without a soldier at the site. Submitted to the U.S. Army's xTech Kinetic Reach program, eligible for direct-to-Phase-II SBIR funding.
Ghost Sled recovers disabled U.S. Army and NATO wheeled and light tracked vehicles in GPS-denied and communications-denied environments, and extracts crew at the same time — so no soldier ever has to walk into a contested recovery site.
An autonomous drone launches ahead of Ghost Sled, builds a 3D picture of the disabled vehicle and terrain, and relays a recovery plan before Ghost Sled ever arrives.
Ghost Sled navigates autonomously to the site — on road or fully denied of GPS and communications — and positions itself against the vehicle.
A hydraulic attachment engages the vehicle's structure directly — not a fixed tow point — so recovery works even on combat-damaged vehicles.
A companion unmanned ground vehicle recovers the crew while Ghost Sled recovers the vehicle. Both return autonomously — mission complete.
We connect proven, already-fielded, made-in-USA components that have never been combined before — a tracked agricultural platform, an off-road recovery attachment, autonomous navigation, and a crew extraction robot. The integration architecture is the innovation, not any single part.
Ghost Sled doesn't ask any single vendor to build something new. Every system below already ships, already works, and is already made in the United States.
ReefLiger's job is the architecture that makes these systems work together as one recovery platform — not reinventing any of them.
ReefLiger has filed a provisional patent covering the core Ghost Sled recovery architecture, including a structural-engagement recovery method that works regardless of a vehicle's tow point condition, and an autonomous ground-anchor system that removes the last manual step from vehicle recovery.
ReefLiger LLC is a defense systems integrator founded in 2026 and based in Casper, Wyoming. We're a small, senior team that designs recovery and support systems by combining best-in-class, already-fielded American technology — rather than building new hardware from a blank sheet.
Ghost Sled, our first program, was submitted to the U.S. Army's xTech Kinetic Reach competition under Topic T5 — Uncrewed Automated Ground Recovery System. We work alongside TeraSteed LLC, an affiliated IP holder contributing thermal-signature-reduction technology to the Ghost Sled platform.
We're glad to hear from Army program stakeholders, teaming partners, and anyone interested in autonomous recovery and defense systems integration.
