AirBoss Defense Group


Press Releases

Sentinel’s involvement with AirBoss Defense Group began with an investment in Critical Solutions International, leading global supplier of landmine and improvised explosive device detection vehicles, systems and support services to U.S. and foreign military forces. Sentinel partnered in the transaction with CSI's founders, Tennessee Valley Ventures, and senior management.

Founded in 1999, CSI has been an important resource to the U.S. Army, U.S. Marines, and the Canadian Armed Forces for testing, developing and supplying landmine detection vehicles and systems. CSI's primary product, the Vehicle Mounted Mine Detection system, is a unique, life-saving, combat-proven vehicle that is blast-survivable, field-reparable, four-wheel steerable, and highly effective at detecting all forms of land-based explosive devices. Today the Husky is a Program of Record with a DX Rating—the highest possible rating granted by the U.S. armed forces. CSI's vehicle systems are designed to enhance the military's mobility by detecting improvised explosive devices and landmines in harsh combat conditions. Its systems also mark and detonate landmines and IEDs during route clearance operations ahead of military convoys. CSI's systems are not only safe to operate, but also save lives and prevent catastrophic injuries to service personnel in combat settings.

In January 2020, CSI merged with the defense subsidiary of publicly traded AirBoss of America Corp. (TSX: BOS) creating a new company, AirBoss Defense Group. With operations in Acton Vale, Quebec and Landover, Maryland, AirBoss Defense Group is a market leader that provides mission-critical and lifesaving personal protective equipment to withstand chemical, biological, radiological, nuclear, and toxic industrial chemical exposure. The combination brings together two highly complementary businesses that are global leaders in personal protective equipment and route clearance solutions. With the extraordinary success of AirBoss Defense Group, AirBoss of America made an offer to purchase the minority ownership we owned, which led to us exchanging our ownership stake in Airboss Defense Group for a stake in AirBoss of America Corp. Sentinel ultimately sold its holdings in AirBoss of America in September 2021 in a highly successful transaction.

Through our 10-year ownership, CSI experienced a long period of contracting defense spending and depressed demand for its products as the U.S. military withdrew from Iraq and Afghanistan and defense spending budgets were constrained. In the face of an exceedingly difficult and protracted market downturn, CSI management team demonstrated extraordinary resilience. They developed new lifesaving solutions for military and healthcare personnel that made possible the merger with CSI that created AirBoss Defense Group. Since then, AirBoss Defense Group has become a critical supplier to the U.S. Government in the fight against the COVID-19 with a suite of products geared to the safety of frontline healthcare workers. CSI’s turnaround reflects remarkable perseverance and determination by its exceptionally talented management team, whose leadership has well positioned AirBoss Defense Group to continue to provide critical lifesaving equipment to the U.S. Government and its allies.

In February 2015, after achieving substantially all of our investment objectives, NAR was sold to another private equity firm.

NAR remains well positioned to continue growing under the leadership of its outstanding management team.
