Ukrainian President Volodymyr Zelensky urged international allies on Monday to provide a package of air-defence systems to cover a critical funding shortfall [1].

The request comes as Ukraine prepares for winter, a period when Russia typically intensifies attacks on energy infrastructure. Securing these resources is seen as vital to maintaining the country's power grid and civilian safety during the coldest months.

During a summit of the ‘Friends of Kyiv’ alliance in Kyiv, Zelensky identified a specific gap in defence procurement. He said Ukraine needs to close a shortfall of 27 billion euros [1] in defence needs before the onset of winter.

Zelensky called for the acceleration of military hardware deliveries. He said allies must speed up the delivery of air-defence systems that the country needs urgently [2].

British Prime Minister Andy Burnham attended the summit and addressed the geopolitical tensions surrounding the aid. He said London will continue to provide defensive assistance to Ukraine despite threats from Russia [2].

The summit focused on the immediate procurement of systems capable of intercepting Russian missiles and drones. The €27 billion [1] requirement encompasses a broad range of defensive needs, but the priority remains the protection of critical infrastructure.

Ukraine has historically faced severe energy shortages during winter months due to targeted strikes on electrical substations and heating plants. The current push for air-defence systems aims to mitigate these losses through a more robust aerial shield.

"We need to close a deficit of 27 billion euros in defense needs before the winter season."

The request for €27 billion in aid highlights a significant funding gap in Ukraine's defensive capabilities just as the seasonal risk of energy infrastructure attacks increases. The UK's commitment to continue aid despite Russian threats signals a continued Western strategy of deterrence, though the scale of the requested funding suggests that current aid levels are insufficient for Ukraine's winter survival strategy.
