A Navy Test Pilot School UH-72 Lakota. They got these a couple of years ago to replace the old TH-6s.
It’s not widely known, but the Naval Test Pilot School is the only military test pilot school in the country that trains helicopter test pilots. Which means that the Army has a 50% stake in the rotary-wing program, supplies half of the instructors, half of the aircraft (including these), and owns half of the billets. A few years ago, we even had an Army officer as CO of TPS.
