Frustrated soldiers and a defense system struggling to repair its way into a fully functioning military. And a new defense minister who will have to regain confidence from army representatives.

Ageing helicopters have proved a big hurdle for the German military. The Bundeswehr has grounded all its 53 Tiger helicopters, after engineers said technical faults needed attention. Defense services were also forced to recall 22 Sea Lynx anti-submarine helicopters in 2014, confirming newspaper reports of malfunction.

The Eurofighter is the German military's most modern fighter jet. As a result of a manufacturing error, only four of the 128 planes were in action in 2018. A pilot was killed in June 2019 when two Eurofighters collided in the northeastern state of Mecklenburg-Western Pomerania, prompting fresh calls for further restrictions on the plane's use.

Tornado fighters have been flying for over 40 years. CDU plans to replace the ageing planes were thrown into question by the center-left SPD in February 2019. But some officials claim flying the Tornado after 2030 could cost Germany around €8 billion ($9 billion) in repair costs.

New Puma tanks for the German military came into use in 2018. Only 27 of the 71 Pumas were immediately ready for deployment — which prompted a fresh backlash against then Defense Secretary Ursula von der Leyen.

New F125 frigates — but they are't ready yet. German plans to replace the old frigates stalled in 2018, due to there not being enough spare parts to make them seaworthy. Officials also said Germany would have to soon stop signing up to NATO and UN missions in the same year — the country just did not have enough ships spare.

She has not been in the job long, but Annegret Kramp-Karrenbauer has inherited a huge problem. Old equipment being grounded is now a regular and pressing occurrence. Former Defense Minister Ursula von der Leyen signed a deal to develop a "Future Combat Air System" in June — which is scheduled to replace Germany's air force by 2040.

West Germany officially joined the trans-Atlantic alliance in 1955. However, it wasn't until after reunification in 1990 that the German government considered "out of area" missions led by NATO. From peacekeeping to deterrence, Germany's Bundeswehr has since been deployed in several countries across the globe in defense of its allies.

In 1995, Germany participated in its first "out of area" NATO mission as part of a UN-mandated peacekeeping mission in Bosnia and Herzegovina. During the deployment, German soldiers joined other NATO member forces to provide security in the wake of the Bosnian War. The peacekeeping mission included more than 60,000 troops from NATO's member states and partners.

Since the beginning of the NATO-led peacekeeping mission in Kosovo, some 8,500 German soldiers have been deployed in the young country. In 1999, NATO launched an air assault against Serbian forces accused of carrying out a brutal crackdown against ethnic Albanian separatists and their civilian supporters. Approximately 550 Bundeswehr troops are still stationed in Kosovo.

In 2016, Germany deployed its combat support ship "Bonn" to lead a NATO mission backed by the EU in the Aegean Sea. The mission included conducting "reconnaissance, monitoring and surveillance of illegal crossings" in Greek and Turkish territorial waters at the height of the migration crisis. Germany, Greece and Turkey had requested assistance from the trans-Atlantic alliance.

In 2003, Germany's parliament voted to send Bundeswehr troops to Afghanistan in support of the NATO-led International Security Assistance Force (ISAF). Germany became the third-largest contributor of troops and led the Regional Command North. More than 50 German troops were killed during the mission. Germany withdrew the last of its troops in June 2021 as part of the US-led exit from Afghanistan.

Forming part of NATO's "enhanced forward presence" in the Baltic states, 450 Bundeswehr soldiers have been deployed to Lithuania since 2017. The battalion-size battlegroups there are led by Germany, Canada, the UK and US to reinforce collective defense on the alliance's eastern flank. It forms the "biggest reinforcement of Alliance collective defense in a generation," according to NATO.
