- "High-Altitude Reconnaissance Plane that shows both enemy position and direction on the mini-map."
- — In-game description.
The H.A.R.P. (High-Altitude Reconnaissance Plane) is a Scorestreak featured in Call of Duty: Black Ops Cold War. It was added as part of Season One content for the game. The H.A.R.P. was also added in Call of Duty: Warzone as a reward from the Ground Fall event during the first week of Season Four.
In Black Ops Cold War, the H.A.R.P operates as a Spy Plane with constant coverage for the entire 30 seconds it is active, as well as showing the direction each enemy is facing. Users of Ghost will be detected by the H.A.R.P even while moving and controlling a scorestreak, unlike the Spy Plane. The scorestreak may also be locked on and attacked by the SAM Turret, shot down by launchers, taking five Cigma 2 missiles or destroyed with the Air Patrol scorestreak, making it significantly weaker than previous versions of the streak.
- The CIA H.A.R.P. retains the callsign Big Eye 6. This is the same callsign for the SR-71 Blackbird in the Call of Duty: Black Ops mission “W.M.D.”
