About Us

Robert J Murphy – CEO and Founder of 5G International Inc.

Robert Murphy conceived, patented, and built the first unmanned, stealthy, surface skimming vessel. Along with holding three United States and International Patents, Murphy has over 40 years of experience in the business, design, development and production of high performance surface and sub-surface vessels.

Murphy is personally responsible for the development of eight generations of unmanned surface vessels (USV’s) and has produced vessels, vehicles, components, housing and related systems for international private and military sectors.

5G International Inc over decades of design has developed 8 generations of unmanned surface vessels. We offer true robotic systems which can be pre-programmed to perform fully-autonomous missions via satellite positioning or by inertial navigation, including full obstacle avoidance offered by our partners Robosys.

Our products are custom engineered to the specific requirements of the marine vessel’s needs. With our experience in the industry, especially for the military and commercial customer, our cutting-edge products include the design, development, training and education of an array of available features. We can assist in what is possible now and what can be developed feasibly.


The pioneering work on the patented OWL /USV was completed in 1988. Mr. Murphy received two patents on the OWL, the first Unmanned Surface Vessel and an advanced design patent. In late 1989 the OWL vehicle was demonstrated for the US Naval laboratories test range in Chesapeake Beach Maryland.

After the test and evaluation of the OWL the United States Navy determined that this new revolutionary novel vessel could be used effectively in 17 different fleet missions. International Robotic Systems then had high-level meetings in late 1989 with Dr. Ron Clark of DARPA (The US Defense Advanced Research Projects Agency). The United States Navy had an immediate operational requirement for shallow water mine detection and neutralization. DARPA arranged meetings at the Pentagon with the Assistant Secretary of Defense for Special Operations (SOLIC).

Mr. Murphy’s second-generation USV, the gasoline-powered, 17-foot Sentinel USV, was a light-duty, jet-driven, prototype with limited functionality – a feasibility project.

Mr. Murphy managed the company’s general business, its marine engineering and naval architecture. His team designed and built the six-meter Ghost Guard USV his third generation USV. The efforts combined in-house developed software for command and control, and third-party commercial off-the-shelf [COTS] hardware and software (e.g., telemetry, navigation, engine diagnostics).

Completed in 2008, the Interceptor has been featured on the Discovery Channel, Signal Magazine, Jane’s Information Group, Armada Magazine, Unmanned Vehicle Magazine, BBC News, IDEX Dubai, DSA Kuala Lumpur Malaysia.

The smallest USV in the program, measuring 3.1m (10.8ft), the Sea Serpent is best suited for harbour and port security and surveillance roles. Its compact size is well suited to be carried onboard large private (super) yachts for individual security purposes.

An autonomous 11m (36 ft) Rigid Inflatable Boat (RIB) that can be operated manned or unmanned, with the insertion/extraction role in mind and therefore aimed primarily at special operations applications.

At 9.3m (30.6 ft) in length, is the largest Murphy-designed USV to date, has a hybrid propulsion system for silent running capable of remaining on station for longer periods of time without refueling and is capable of fulfilling a wide variety of security, surveillance and potentially intervention applications.

Introduced in 2015, Hydra is a 4-meter RHIB, high speed unmanned surface vessel (USV) designed for surveillance and security missions in near coastal areas and can be carried by a larger craft.
