ONR - Large USV Requirements

To support Navy mission requirements, key attributes of Large USVs include higher top speed, extended vessel range and cruising speed, and high reliability. Specific attributes of the desired Large USV include:

  • Endurance of 4,500 nm or more at 19 knots transit speed or higher
  • Top speed of 27 knots (Threshold); 30+ knots (Objective) in calm water
  • Capable of remaining sufficiently stable to operate payloads in up to Sea State 5 (per NATO STANAG 4194)
  • Capable of surviving in Sea State 7 (per NATO STANAG 4194) or higher
  • Capable of operating for 30 days (Threshold) or more 90 days (Objective) without any manned maintenance, e.g. to shift lubricating oil or fuel oil strainers
  • Topside space and sufficiently reinforced deck to support 40,000 lbs of deck cargo
  • Ability to embark/debark crew in Sea State 5 (per NATO STANAG 4194) or less (request identify how this would be accomplished)
  • 300 kW (Threshold) to 500 kW (Objective) power generation capability, with at least 75 kW reserved for payload.
  • Equipped with redundant main engines, marine propulsion gear, and electrical generators such that failure of any single component will not reduce vessel maximum speed below 16 knots (Threshold; 20 knots Objective) nor reduce electrical generation capacity below 200 kW. Short-term berthing for no less than four Sailors to Surge personnel standards (e.g. Part II, Figure 4-4) in NAVSEA Technical Publication T9640-AC-DSP-010/HAB Revision 1 dated 21 December 2016.
  • Notional tasks for crew during short-duration stays on the vessel include piloting in/out of harbor, fueling at sea, and conducting emergency repairs topside and/or in engineering spaces
  • Short-duration crew will be unarmed and the vessel will not require a dedicated rescue vessel to recover a person from the water. One life raft shall be included.
  • Capable of piloting into and out of port with a tug and a crew of 4 or fewer (Threshold); remote piloting without a tug (Objective)
  • Navigation autonomy
    • Threshold: Capable of autonomous safe pilotage to include path planning, obstacle avoidance and mission behaviors. Pilotage shall require the ability to navigate around charted obstacles to include buoys and waters shallower than the vessel's depth
    • Objective: Threshold, plus capable of autonomously sensing its environment and maneuvering consistent with the International Regulations for Prevention of Collisions at Sea (COLREGS)
    • Autonomy system shall be IA compliant.
  • Autonomy implementation plans, specifically industry's potential solutions to include leveraging existing industry systems or the option for GFE autonomy
  • An autonomy architecture that allows for modularity of different autonomy components to include sensors, software components (i.e. navigation, obstacle avoidance, machinery control, health monitoring, mission behaviors) and payloads. This architecture will be capable of being monitored and controlled remotely by an off-board Control system. The USV shall be capable of being monitored and controlled by 1 person and ideally multiple USVs handled by 1 person.
  • Resistant to boarding from unauthorized personnel while easy to access by appropriately trained and equipped U.S. forces
  • Resistant to physical tampering from unauthorized personnel
  • Able to be delivered and/or made available in 16-18 months

The Large USV may be temporarily manned with as many as four personnel for periods of up to seven days.
