A member of the US House of Representatives has called for enhancement of Washington's defense capabilities in response to Tehran's unveiling of a new loitering munition drone.

"Iran’s Rezvan loitering munition and its growing drone capabilities underscores the need for the US to bolster its own defense capabilities," said Congressman Pat Fallon in a post on his X account on Saturday.

"Innovative anti-drone defenses and countermeasures are essential to our military's readiness," he added.

His comments came two days after Iran’s Islamic Revolutionary Guard Corps (IRGC) unveiled its latest loitering munition drone, the Rezvan, during military drills codenamed Great Prophet 19.

The drone, with a range of 20 kilometers and an operating time of 20 minutes, is designed for rapid deployment and targeted attacks, particularly in complex terrain, according to the IRGC.

The suicide drone is fired from a cylindrical launcher and transmits live video to the operator, allowing for precise target selection and engagement, IRGC media Tasnim reported.

The Great Prophet 19 exercise was the latest in a series of drills conducted by Iran's military to showcase its capabilities and project a message of strength in the region, following consecutive defeats for its allies since September.
