GB-Challenger Class is a modular-concept high-speed work craft built on an aluminum, stainless steel, and rubber platform. Powered by twin 660-HP Caterpillar diesel engines driving 20-inch impeller NOMERA water jet propulsion units, Challenger is fast, maneuverable, and competent in coastal waters, rivers, and open seas. Challenger is available in models ranging from 7 meters to 16 meters. A variety of drop-in modules allow Challenger to adapt to a wide range of military and commercial missions.

Additional Radix Marine Craft

40+ Knots, Extremely Maneuverable

The Challenger's advanced hull design and turbo-charged engines coupled to powerful water-jet pumps give it unparalleled speed and maneuverability.

Accelerates from 0 to 40 knots in 10 seconds

At 40+ knots, turns 180 degrees in 1.5 boat lengths

Full-thrust reverse, 40 knots to full-stop in 2 boat lengths

Shallow 1-meter draft capable of river and coastal patrol missions

Rapid Reconfigurable Modules

All of the GB-Challenger craft have been designed to be reconfigurable platforms which will accept mission modules that plug into the front deck section of the basic craft. Available mission modules range from dive salvage, drug interdiction, environmental response, and firefighting, to mine countermeasures and weapons deployment. The Challenger's drop-in modules can be installed in minutes with a simple dock-side lift.

U.S. Navy Testing

The GB-12 296 Challenger has performed exceptionally well in demonstrating the capability of the product to meet the requirements of potential clients. Throughout its research and development history, the GB-Challenger Class Craft has participated in testing and trials with the U.S. Navy and major defense contractors. Interest in IMPII's capability to promote their products in the global market, and an understanding of the craft’s unique capabilities, has led several major defense contractors into strategic relationships with IMPII. The essence of these agreements is to jointly develop new technologies for integration into mission modules which meet the tactical requirements of military organizations worldwide.

The U.S. Navy’s interest in the GB-Challenger has increased over recent years resulting from the demonstrated performance capability of the GB-Challenger Class Craft. Recent performance indicators include an independent study conducted for the U.S. Navy to meet the Navy’s requirements for Survivability, Transportability, Remote Control Capability, and Cost Effectiveness, in which study, IMPII’s 12 and 16 meter craft consistently rated #1 and 2, respectively.
