近期卫星图像显示，俄罗斯在其多个空军基地建造了飞机防护设施，以应对乌克兰无人机袭击。这些措施包括建造带有圆形屋顶和厚重防爆门的加固掩体，部分设施还覆盖土层以增强防护。英国国防部评估认为，此举是对乌克兰无人机成功打击的回应，乌克兰已越来越多地依赖国产无人机攻击俄罗斯境内的军事目标。俄罗斯还采取了其他防护措施，如在停机坪上绘制假飞机以及用轮胎覆盖轰炸机，但这些措施的有效性尚不明确。乌克兰的远程无人机攻击已成为其在战争中的亮点，尤其是在俄方限制其使用西方导弹攻击俄本土的情况下，乌克兰大力发展国产无人机。

🛡️ 俄空军基地升级防护措施：俄罗斯正在其多个空军基地，包括Millerovo、Kursk Vostochny和Hvardiiske，建造新型加固飞机掩体。这些设施配备了圆形屋顶和厚重的防爆门，旨在保护飞机免受乌克兰无人机袭击。

🌍 应对乌克兰无人机攻势：英国国防部指出，这些防护措施是俄罗斯对乌克兰成功实施的多次无人机袭击的回应。乌克兰已将国产无人机作为一种有效手段，用于打击俄罗斯境内的高价值军事目标，包括空军基地。

🛩️ 多元化防御策略：除了建造加固掩体，俄罗斯还采取了其他战术来保护其战机，例如在停机坪上绘制假飞机以及用轮胎覆盖轰炸机，这些措施旨在混淆乌克兰的侦察和打击目标，但其整体效果仍有待观察。

💡 乌克兰无人机战略地位提升：在西方限制乌克兰使用远程导弹攻击俄本土的背景下，乌克兰大力发展和部署国产长程无人机，使其成为在消耗战中打击俄罗斯军事工业设施和交通网络的关键能力。

Russia has built hardened shelters to protect its vulnerable aircraft at several bases following a string of long-range Ukrainian drone strikes, a new Western intelligence assessment suggests.

Britain's defense ministry this week published satellite imagery from early June, collected by the US company Planet Labs, that shows newly constructed shelters at three Russian air bases behind the front lines.

The shelters, which consist of dome-shaped rooftops and thick blast doors, were photographed at Russia's Millerovo, Kursk Vostochny, and Hvardiiske air bases. Some structures were seen covered with earth for added protection that could help shield against shrapnel or other debris.

The UK said in a Tuesday intelligence update that Russia had launched efforts to protect vulnerable aircraft at several bases "in response to numerous successful" Ukrainian drone attacks. Millerovo, just a few miles across the border, for instance, was targeted just last week.

"The construction of these hardened aircraft shelters provides a layer of protection to aircraft deployed to Russian airbases against future" Ukrainian drone attacks, the UK explained.

Hardened shelters are one of several tactics that Russia has turned to in an effort to protect its fighter jets from the Ukrainian attacks. Moscow has also painted decoy warplanes on the tarmac at its air bases and even covered its bomber aircraft with tires in an attempt to confuse Kyiv's targeting and mislead the drones. It's unclear, however, how effective these protective measures have been.

Ukraine's long-range drone attacks have been a bright spot for Kyiv during the three-and-a-half-year-long war, which has transitioned from a maneuver conflict to one of attrition, featuring largely static front lines and standoff strikes from distance.

The US long prevented Ukraine from using Western-provided missiles to strike across the border and inside Russian territory. That arsenal was also quite limited. As a workaround to these restrictions, Kyiv invested heavily in domestic drone production.

Over the past year, Ukraine has repeatedly used homemade long-range drones to strike a range of high-value military and energy targets inside Russia, including oil terminals, ammunition depots, weapons-making factories, and air bases.

Russian air bases have been a particular focus for the Ukrainian military, as Moscow uses these sites to stage deadly attacks against troops and civilians, relying on missiles and guided bombs.

On Tuesday, conflict analysts at the Institute for the Study of War, a US-based think tank, said in a battlefield assessment that Ukrainian forces "appear to be intensifying a long-range strike campaign against Russian military industrial facilities and transport networks."
