NATO has strengthened its air defense presence in the Baltic region with the deployment of six Belgian F-16 Fighting Falcon fighter jets to Lithuania.

The Belgian aircraft arrived at Siauliai Air Base in early November and have assumed enhanced air defense responsibilities alongside Italian forces already operating in the country. Belgian aircraft will operate alongside Italian Eurofighter Typhoons in Lithuania and Turkish F-16s deployed to Estonia.

The deployment includes around 100 Belgian military personnel and forms part of NATO’s expanded air and missile defense framework, which brings together fighter aircraft, surveillance systems, command and control capabilities, and ground-based air defense systems.

Belgian F-16s Reinforce NATO Presence in Lithuania

The Belgian Air Force detachment has joined the Italian Air Force, which remains the lead nation responsible for NATO’s air defense mission in Lithuania. Italy began its latest deployment in July 2026 with four Eurofighter Typhoon fighter jets operating from Siauliai Air Base.

Belgium’s six F-16 Fighting Falcons add further fighter aircraft to the NATO presence in the country, strengthening the alliance’s ability to monitor and protect its eastern airspace. The deployment also reflects the shared responsibility among NATO members for maintaining air security in the Baltic region.

Türkiye has separately deployed five F-16 fighter jets to Amari Air Base in Estonia, where its aircraft took over air defense duties from Portugal on July 31, 2026. The Turkish deployment is scheduled to continue until November 30, 2026.

Estonia, Latvia and Lithuania rely on NATO allies to provide fighter aircraft for the protection of their airspace, as the three countries do not maintain independent combat air forces capable of carrying out this mission. Rotating deployments from alliance members therefore remain central to NATO’s air defense arrangements in the region.

NATO Expands Baltic Air Policing Into a Wider Air Defense Mission

The Belgian deployment comes after NATO expanded its existing Baltic Air Policing Mission into a broader NATO Air Defense Mission in 2026. The change was agreed at the NATO Summit in Ankara in July, with the new framework becoming operational on August 1.

The expanded arrangement moves beyond the earlier mission’s primary focus on monitoring allied airspace and responding to unauthorized aircraft. It establishes a wider Integrated Air and Missile Defense posture designed to address threats from crewed military aircraft, unmanned aerial vehicles (UAVs), cruise missiles and ballistic missiles.

Under the new framework, NATO combines fighter aircraft with surveillance capabilities, command and control systems, and surface-based air and missile defense systems. This layered approach is intended to improve the alliance’s ability to detect, track, and respond to different types of airborne threats across its territory.

The framework also provides a more integrated approach to coordinating national military capabilities. Rather than relying primarily on fighter aircraft, NATO can bring together air and ground-based defense assets to respond to potential threats in a coordinated manner.

Allied Air Command Coordinates NATO Air Defense

NATO’s Allied Air Command (AIRCOM), based at Ramstein Air Base in Germany, oversees the alliance’s air defense activities and coordinates the capabilities contributed by member countries.

Its three Combined Air Operations Centers (CAOCs), located in Spain, Germany and Norway, provide 24-hour command and control of NATO air defense activities. They plan, direct and coordinate allied air operations, including the deployment and interception tasks of military aircraft across their respective areas of responsibility.

The Belgian deployment in Lithuania, together with Italian aircraft in the country and Turkish fighters in Estonia, strengthens NATO’s ability to maintain a coordinated defensive presence across the Baltic region. The expanded framework is designed to protect allied territory, populations and military forces during peacetime, periods of crisis and potential conflict.
