Blue Ops completed the first integration of Volvo Penta’s 320-horsepower D4-320 diesel engine and DPI drive into its Variant 7 USV and disclosed that the vessel had entered full-rate production.

  • The propulsion configuration is connected to Variant 7’s autonomous navigation, remote-operation, mission-planning and payload-management architecture.
  • Blue Ops positions the 24-foot craft for high-speed littoral operations, with diesel propulsion adding a commercially supported option for endurance and serviceability.
  • The production disclosure is distinct from the propulsion test itself and marks a transition from development-stage integration to serial manufacturing.
