US drone losses in Iran war near $1 billion: Report

US drone losses in the Iran conflict are nearing $1 billion, reports say. The latest setback was the crash of a $240 million MQ-4C Triton near the Strait of Hormuz. Separate reports say 24 MQ-9 Reaper drones were also lost. The rising toll highlights growing risks to costly American surveillance aircraft in increasingly contested Gulf airspace.
