Baltic Drone Exposes Shelter Gaps

A Romanian F-16 fired an air-to-air missile over southern Estonia around midday on 20 May. Its target was a Ukrainian drone, knocked into allied airspace by Russian GPS jamming, which came down 30 metres from a farmhouse in Põltsamaa (ERR, Aerotime). Nobody was hurt.

It was NATO's first aerial interception over a Baltic state. The missile did its job. The civilian protection system beneath it looked far less ready.

Ten Incursions, One Government Down

Since March, at least ten drone incursions have reached four NATO states, roughly one every five days (Defence News). The pattern is now familiar: Ukrainian drones aimed at Russian energy infrastructure near St Petersburg are pushed off course by electronic warfare and end up over allied territory.

On 7 May, one hit a Latvian oil depot. On 15 May, Finland closed Helsinki airport. On 20 May, Lithuania issued its first mass civil alert, sending the president and parliament into shelters (Euronews).

Latvia took the heaviest political blow. Prime minister Evika Siliņa resigned on 14 May after the defence minister was forced out over the Rēzekne depot strike (Washington Post).

Ukraine says the deviations are caused by "deliberate" Russian electronic warfare (Ukrainska Pravda). Russia's foreign intelligence service chose a different route, inventing a claim that Latvia was allowing Ukrainian drone launches from its territory and warning that "the coordinates of decision-making centres on Latvian territory are well known" (Atlantic Council).

NATO secretary general Mark Rutte put the blame back on Moscow. The drones are crossing allied airspace, he said, "because of the reckless, illegal full-scale attack of Russia" (Euronews).

Thirty-Five Lost Years of Shelter Neglect

The drone that fell at Põltsamaa was carrying fuel, but there was no confirmed warhead. Had it been armed, many people nearby would have had little idea where to go.

Estonia sent mobile alerts during the incident through a warning app that had been launched one day earlier for a military exercise (ERR). Mandatory shelters in new buildings will only take effect in March 2028. There are no public sirens.

That weakness is not Estonian alone. Germany has 579 functioning shelters left from a Cold War stock of 2,000. Berlin has none (Taz). Poland can shelter 3.8 percent of its population (Business Insider Poland). Romania lists 4,538 civil protection shelters, but in Tulcea, a frontline city close to the Ukrainian border, none of ten public facilities works (Adevărul).

Finland is the exception because it never dismantled its Cold War network. It can protect most of its urban population.

Governments are now trying to catch up. Germany approved €10 billion for civil protection on 20 May, its largest such investment since reunification (German Federal Government). Poland has set aside 22.5 billion zloty through its EU Recovery Plan, with major shelter construction due to begin in 2027 (Money.pl).

The harder problem sits in EU law. Civil protection is a "supporting competence" under Article 196 of the Treaty on the Functioning of the European Union, which means Brussels can coordinate and help pay, but cannot order a government to build shelters or install sirens.

There is no common alert standard either. On 20 May, Lithuania used cell broadcast, Estonia used a pilot app, and Latvia warned only border municipalities. Three NATO allies faced the same type of threat with three different systems.

What the Missile Cannot Fix

Russian electronic warfare makes these incidents useful to Moscow because it leaves room for denial. GPS jamming blinds a drone's navigation. Spoofing gives it false coordinates. Some drones pushed off course may then autonomously lock on to the nearest target that matches their visual programming.

Whether Russia is actively steering drones into NATO airspace, or creating the conditions for them to drift there, matters politically. For civilians under the flight path, the danger is much the same.

NATO showed on 20 May that it can shoot down a stray drone. The Romanian pilot had clear skies and visual contact. The next pilot may have neither.

For Irish readers, the lesson is not only about NATO's eastern flank. It is about the gap between military interception and civilian protection, a gap that Europe allowed to widen after the Cold War. The alliance can now hit the threat in the air. Under current EU law, Brussels still cannot make national governments protect the people underneath it.
