Even with the Eurofighter's arrival, the Panavia Tornado remains very much key to the Luftwaffe's front-line capabilities. Just two wings still fly the type, these having been re-organised recently as Taktischen Luftwaffengeschwader (Tactical Air Wings) - the aircraft at RIAT 2015, one each for the flying display and static park, will hail from Taktisches Luftwaffengeschwader 33, which operates the Tornado IDS (Interdictor Strike) variant from Büchel near Koblenz. The unit notched up its 185,000th flying hour on the Tornado during 2014, having received its first examples to replace the F-104 Starfighter in 1985. The aircraft is still being upgraded, and recently TaktLwG 33 has been receiving Tornados updated to the new ASSTA 3 software standard, allowing the employment of the Laser Joint Direct Attack Munition precision-guided bomb and improving the jet's self-protection suite amongst many other enhancements. Future upgrades will include the installation of new cockpit display screens. Germany thus intends to keep the Tornado in service until 2025.
