It expensive drone, not so easily shot down such drone
On 20 June 2019, Iran's Islamic Revolutionary Guard Corps shot down an MQ-4C drone in the Strait of Hormuz near Kuhmobarak in Iran's southern province of Hormozgan. Iran claimed it was in their airspace, while the US claimed it was in international airspace. An anonymous U.S. official initially claimed it was an MQ-4C Triton drone, but the U.S. Central Command later confirmed it was an RQ-4A drone assigned to the Navy's Broad Area Maritime Surveillance (BAMS) program.
