The Patroller 3, designed as a semi-buoyant UD dirigible aircraft, suits many aerial surveillance and patrol duties. LSL plans to help the originator (AHA) further develop/provide them, but with H2 power instead of hydro-carbon fuels together with electric drive thrust systems. The design enables its crew to work in shirt-sleeves in quiet, low-vibration comfort over several days.

Loiter ability allows the crew to observe and report with unrivalled ease, either at low or high altitude for safety. Long endurance at moderate airspeed or dash airspeed for rapid relocation are enabled. In addition, integration of day/night vision systems allows problematic situations to be found and the aircraft provides a steady roving command centre able to track/follow & direct action.
Applications
As well as use for national security, the Patroller 3 also is suitable for use in scientific and environmental applications. Examples include oceanographic study, monitoring whales and other sea creatures, oil slick, garbage and fisheries patrol, as well as inland waterways/regional survey.
Features
Originally designed as a coastal patrol type, but great for wide ranging inland duties, the Patroller 3 has the following capabilities:

- Roomy, quiet cabin for 4+ crew
- “Spotter” station in the flight compartment
- Workstation with: computing, communications, planning and navigation systems
- Small galley unit
- Two bunks in curtained-off compartment
- Toilet & washbasin at aft end
- Observation stations on starboard side
- Day and night optical systems
- Maximum airspeed around 75 knots
- 100 hour endurance, un-refuelled
- No ground crew for take-off and landing.

LSL is glad to be working with AHA, Luffships Canada (LSC) and our seasoned teams/partners to establish useful buoyant aircraft at affordable prices that work reliably with little fuss serving people’s daily needs.
