Analyst Note:
This image shows an AR731-4000 Wankel-type engine produced by UAV Engines Ltd. of the United Kingdom, used in an Israeli Harop munition. Variants of the Harop used in the 2020 Nagorno-Karabakh War featured a similar Wankel engine, but were marked to indicate a different manufacturer and model name: “MBT ENGINE” and “H2251-5100-503”.
