The intensity of the drone and missile war in Ukraine has laid bare gaps in European states’ air defences that experts say will be difficult, time-consuming and costly to plug. Anti-air systems will likely have a starring role at the Paris Air Show starting on Monday, predicts Richard Aboulafia, managing director of AeroDynamic Advisory. “You’re going to see a lot of talk about production capacity for missiles. The market for missiles is easily the fastest growing segment of the industry and yet the manufacturers simply can’t keep up,” Aboulafia told AFP. Western countries had enjoyed total mastery of the skies since the end of the Cold War and largely dropped the powerful defences once designed to protect NATO forces from Soviet aircraft. France got rid of eight of its nine anti-aircraft artillery regiments, MPs flagged up in a recent report. But NATO countries have been turning to air defence again in recent years as more states have acquired cruise missiles, short-range ballistic missiles and drones, said Mark Cancian, a retired US marine colonel who is a senior adviser at the US-based Center for Strategic and International Studies (CSIS). “They started it, but basically didn’t get too far,” Cancian told AFP. “In another five years, I think there’ll be a lot more out there, but that doesn’t help Ukraine right now,” he added. With anti-air systems and the missiles they fire lacking, the West is struggling to respond to Ukraine’s pleas for supply – whether for short- or long-range defences. Berlin plans to spend five billion euros on anti-air from a 100-billion-euro ($110 billion) fund for rebuilding its armed forces in the coming years, with the same amount budgeted in Paris for the period to 2030. On the industry side, European missile maker MBDA has in recent months signed contracts worth two billion euros with France and Italy to supply 700 Aster missiles, used especially in the SAMP/T system. And Poland will spend 2.2 billion euros on 44 launchers and hundreds of CAMM missiles. ‘Euro sky shield’ Led by Germany, 17 European nations last year banded together on air defence with the “Euro Sky Shield” project – although France, Italy and Poland have all stayed out. The scheme would involve joint procurement for short-, medium- and long-range systems, including the German-made Iris-T, the American Patriot and the US-Israeli Arrow-3. “It makes enormous sense” to harmonise across allied countries, Aboulafia said. Nevertheless, “whenever NATO tries to standardise, obviously big decisions have to be made in terms of who takes lead on production and design”, he added. “We’ve seen this movie before and the big problem is always France,” which is reluctant to cede industrial leadership, Aboulafia said. “Germany’s proposal does not take European security interests sufficiently into account, has failed to convince partners, and leaves many questions unanswered on the strategic, military, industrial, and economic levels,” Berlin-based think-tank SWP wrote in a recent report. By choosing US and Israeli technology rather than European, the German-led plan is also “at odds with the goal of strengthening Europe’s industrial and technological defence base”, SWP added.
