Florennes Air Base (French: Base aérienne de Florennes),[2] also known as Base Jean Offenberg, (ICAO: EBFS) is a Belgian Air Component (formerly the Belgian Air Force) military airbase, compliant to STANAG 3712 category 8 (and category 5 during quick reaction alert operations), located 2 nautical miles (3.7 kilometres; 2.3 miles) east-south-east of Florennes,[1] in the Walloon municipality of Belgium.

It was recaptured in September 1944 and became known as Advanced Landing Ground (ALG) A-78, after which Allied units operating from here included the United States Air Force (USAF) 430th Fighter Squadron, flying Lockheed Lockheed P-38 Lightnings in the ground attack role, and the United States Army Air Forces (USAAF) 422nd Night Fighter Squadron, flying Northrop P-61 Black Widows.

The TLP is a joint training programme, originally formed in 1978 by defence members from six NATO countries at Fürstenfeldbruck near Munich in West Germany, and previously based at Jever from 1979.

Whilst at Florennes, the TLP conducted multilateral military flying training courses, and expanded to include creating formalised documentation for NATO doctrines, along with other academic studies relating to allied air forces.
