Germany is currently developing plans to significantly expand its bomb-proof shelter network, as expressed by Ralph Tiesler, the head of the Federal Office of Civil Protection and Disaster Assistance (BBK).

Tiesler, highlighting the need for readiness against potential aggression from Russia within the next four years, stated that Germany's current state of preparedness is inadequate.

He emphasized that the long-held belief in Germany that war was not a foreseeable event has transformed in light of recent geopolitical developments.

In a recent interview with the Süddeutsche Zeitung, Tiesler underscored the urgency of the situation, citing an increasing concern over the risk of a large-scale conflict in Europe.

He called for a national effort to rapidly convert existing subterranean structures such as tunnels, metro stations, underground garages, and public building cellars into protective shelters, aiming to create capacity for approximately one million people.

The need for immediate action stems from the ongoing conflict in Ukraine, which has heightened security fears across Europe, particularly in neighboring countries such as the Baltic states, Poland, and Germany.

Recent missile strikes in Kharkiv, Ukraine, resulting in civilian casualties, have further fueled these anxieties.

Currently, Germany possesses about 2,000 bunkers and protective shelters from the Cold War era; however, only approximately 580 are operational, with most requiring costly renovations.

These facilities can accommodate around 480,000 individuals, constituting a mere 0.5% of Germany's population.

In contrast, Finland boasts 50,000 protection rooms, sufficient for around 4.8 million citizens, or about 85% of its population.

Tiesler also pointed to the need for improved public information systems, including better apps, road signage, and upgraded warning sirens to help citizens locate available shelters.

He expressed concerns over the cybersecurity of existing warning applications, calling for enhancements to protect these systems from potential threats.

Tiesler urged the German government, led by Friedrich Merz, to secure necessary funding for these initiatives.

While the government acknowledges the necessity of these plans, formal budget allocations have yet to be established.

Financial resources are anticipated to be drawn from the recent suspension of Germany's debt brake in March, which allows for increased spending on military, infrastructure, and civil defense.

Estimates suggest that Germany will require at least €10 billion (£8.4 billion) over the next four years to address its civil defense needs and an additional €30 billion over the next decade.

Tiesler has proposed the creation of a civil protection service, either compulsory or voluntary, and encouraged citizens to prepare for emergencies by stockpiling supplies to last for a minimum of 72 hours, with a suggestion to aim for 10 days.

He echoed the recommendations made by various European governments regarding personal preparedness in anticipation of possible disruptions.
