NATO fighter jets scramble as Russian drones breach airspace in multiple eastern countries.

Estonia has completed the Kipu radar station on Hiiumaa, which uses a Ground Master 400 Alpha long-range radar capable of detecting targets up to 515 km away and at altitudes up to 30 km.
Ukrainian forces attacked the Russian port of Ust-Luga in the Leningrad region around the same time, causing a fire and reporting damage at the site.
Romania reported two aerial targets near Vylkove late on Sept. 1; two Spanish F-18 fighters and a Romanian military helicopter were scrambled, but no border violation was detected and the alert was lifted at 1:05 a.m.
In Latvia, a drone approached Narva and, around 02:00 local time, about 10 drones were detected near the border; at about 03:00, one drone turned toward Narva before veering back toward Russia, prompting defense measures.
Latvia issued two airspace warnings overnight—first a lower-level yellow alert in Ludza, followed by an alert in Alūksne; the Alūksne warning was lifted at 04:17 a.m., with residents advised to stay indoors and use the two-wall principle while waiting for the threat to pass.
Estonia, Latvia, and Romania scrambled NATO fighter jets on September 1 after drones linked to Russia's Ukraine war neared or crossed their borders. Albeu reported that several drones illegally entered Estonian airspace, triggering immediate alerts across the NATO alliance's eastern flank. The incidents underscored growing hybrid threats as the Russia-Ukraine conflict spills into neighboring countries.
Latvia detected about 10 drones near its border around 02:00 local time, with one turning toward the city of Narva before veering back toward Russia, according to SANA. Romania's radar systems also picked up two aerial targets near Vylkove during Russian strikes on Odesa. All alerts were eventually lifted after military response confirmed no sustained violations.
Turkish NATO fighter jets were dispatched after drones crossed into Estonian airspace on September 1. Militarnyi reported the intrusion occurred during a Ukrainian drone attack on Russian targets. Estonia's defense ministry confirmed the incident but did not specify the drone origin or quantity of aircraft that violated the border.
Estonia is now expanding its detection capabilities. The country recently completed the Kipu radar station on Hiiumaa island, featuring a Ground Master 400 Alpha long-range radar that can detect targets up to 515 kilometers away at altitudes reaching 30 kilometers. This upgrade enhances early warning systems across the region.
Latvia issued two separate airspace warnings overnight as drones maneuvered near its eastern border. A yellow alert covered Ludza, followed by a second warning in Alūksne around 02:00 local time. NATO Baltic air-policing fighters scrambled in response to the threat.
One drone approached the city of Narva and turned toward it before reversing course back toward Russia around 03:00 local time. The Alūksne alert was lifted at 04:17 a.m. after military assessment. Authorities advised residents to stay indoors and follow the two-wall principle—remaining behind two building walls—while the threat persisted.
Romanian radar systems detected two aerial targets near Vylkove late on September 1 as Russian strikes hammered the Ukrainian port city of Odesa. Spanish F-18 fighters and a Romanian military helicopter were immediately scrambled to monitor the situation and provide air defense coverage.
Military assessment confirmed no border violations occurred during the incident. The alert was lifted at 01:05 a.m. after Spanish and Romanian aircraft determined the targets posed no immediate threat to Romanian territory. The response demonstrated NATO's rapid coordination along the eastern frontier.
The September 1 incidents have intensified discussions within NATO about forming a joint drone-defense group to address hybrid threats. Eastern European members—particularly Estonia, Latvia, and Romania—face constant exposure to unmanned aircraft activity linked to the Ukraine conflict. The proposed defense arrangement would improve intelligence sharing and coordinated response protocols.
These airspace incursions reflect the war's geographic expansion without formal escalation. Drones have become tools for reconnaissance, testing air defenses, and striking infrastructure across borders. NATO's focus on collective drone defense reflects the need to protect member states from unconventional threats that fall below traditional military engagement thresholds.
