Iran has issued a navigational notice indicating the closure of a specified area within its airspace to conduct missile drills on Thursday, February 19, 2026. The navigational alert, marked with the code "A0605/26", reveals that the missile exercises will take place for a continuous period of 10 hours, starting from 7 AM until 5 PM local time. This airspace restriction covers an area from ground level to 10,000 feet (approximately 3,000 meters), signifying increased military readiness and testing.

The geographic analysis conducted by Al Jazeera's investigative unit estimates that the area designated for these military drills spans approximately 47,500 square kilometers, with a length of 1,139 kilometers and a width nearing 40 kilometers. Notably, the flight path of the navigational notice traverses four Iranian provinces: Yazd, Kerman, Sistan and Baluchestan, and Hormozgan, extending into the Gulf of Oman by 65 kilometers. This underscores the strategic importance and the potential implications for regional security.

Furthermore, this missile drill comes amid a perceived increase in military activities from Iran, as previous analyses by Al Jazeera highlighted 47 navigational alerts issued by Tehran since early January. These actions reflect Tehran's commitment to enhancing its defensive and offensive military capabilities in response to regional tensions and underscore the growing military assertiveness that may provoke concerns among neighboring countries and international observers.
