Who can resist the Batman-like allure of shooting a grappling hook and line that lets you cross a gorge or scale a building? Those in the special operations, first responder and maritime communities see this plummet gun as a must-have tool.

Battelle has developed a successor to a longtime Navy staple — a pneumatically powered grappling gun that deploys a hook and line higher, further, more quietly, and more reliably than its predecessor.
The system has been featured on the popular TV show MythBusters and The Military Channel’s Weaponology and continues to captivate those who see it in action.

The Tactical Air Initiated Launch (TAIL) system is used to propel a titanium grappling hook towing a Kevlar line for use in Visit Board Search and Seizure (VBSS) operations. It also can be used for fire rescue operations, life vest deployment, or other activities. The TAIL system, using compressed air to launch the hook, can clear an obstacle up to 100 feet high and up to 60 feet away. “The TAIL system lets the user fire a grappling hook without the noise, explosives, or safety issues of powder-driven units,” said Jim LaBine, the TAIL system designer. “That’s important for special operations but the system is adaptable and can be used in many applications.”


Besides enhanced performance at reduced cost, the TAIL system’s simple, rugged design boosts safety and reliability with the advantage of low maintenance. Its simplicity has another benefit: the system can throw any object that fits into its barrel.

Potential uses include:
Tactical hook and line or hook and ladder deployment
Line deployment for ship to ship re-supply
Line deployment for water or fire rescue
Life vest deployment for Coast Guard and rescue units
Mine clearance
Delivery of sensitive electronic payloads
