Nearly 500,000 Russian soldiers killed in Ukraine, top UK intel chief says

Nearly half a million Russian soldiers have been killed in Ukraine since 2022 — a death toll exceeding total American losses in World War II — the head of Britain’s top intelligence agency said Wednesday, relaying one of the highest fatality figures any Western government has put on Russia’s war in Ukraine yet.

Russia is now losing roughly 1,000 troops a day in killed and wounded along the front, according to Ukraine’s General Staff.

Western officials are reaching a consensus that Ukraine has gained a serious edge on the battlefield for the first time in years as Russia struggles to break through Ukraine’s multilayer air defense or stand up to Kyiv’s growing arsenal and strengthening counteroffensive.

“[Russian President Vladimir] Putin is going backwards on the battlefield, with new intelligence showing that almost half a million Russian soldiers have been killed since the conflict began,” the UK’s GCHQ intelligence director Anne Keast-Butler said Wednesday.

Until now, Western governments have hedged on Russia’s total losses, citing only a combined killed-and-wounded of around 1.2 million by late 2025.

The new figure recasts that picture: If nearly half a million Russian troops are dead, hundreds of thousands more are almost certainly wounded — and Moscow’s real casualty cost is far steeper.

The disclosure hardens a growing consensus: Russia is on its heels for the first time since the war’s opening months.

Russian battlefield gains are “approaching net zero” as Ukrainian forces are beginning to break out of the positional warfare that has gripped the front since 2023, the Institute for the Study of War concluded this week, after Russia lost 116 square kilometers of Ukrainian territory in April — the first net territorial loss in 20 months.

“This should now be regarded as an official estimate given its source,” Michael Clarke, former director-general of the Royal United Services Institute, told CBS News .

The real toll “might well be higher” because Russian forces are “so neglectful of their front line wounded,” Clarke said.

The figure broadly tracks an earlier Dutch military intelligence assessment that put Russian “permanent losses” at roughly 1.2 million, including more than 500,000 killed.

It runs well above the floor that independent Russian investigators have documented: more than 108,000 Russian war dead individually named through open-source reporting and an extrapolated minimum of around 350,000, according to Meduza .

U.S. intelligence agencies have not publicly endorsed a Russian fatality-specific estimate of their own, but the Office of the Director of National Intelligence assessed in March 2025 that Russia had suffered more than 750,000 killed and wounded.

Britain’s new estimate, covering only the dead, suggests Russia’s total casualty bill now runs far higher than either U.S. assessment noted.

Ukraine’s General Staff has put cumulative Russian losses higher still, at roughly 1.36 million killed and wounded.

The Russian casualty count came up during a broader discussion about Russian hybrid operations targeting the UK, including cyberattacks on critical infrastructure, sabotage attempts and efforts to smuggle Western technology to Moscow’s defense industry, according to British intelligence.

GCHQ is “working tirelessly with intelligence and defence partners to degrade and reduce the Russian threat,” Keast-Butler said.

For now, Moscow is replacing those losses through a recruiting machine built on cash signing bonuses, prisoner conscription and waves of North Korean troops dispatched by Pyongyang to backstop the front, allowing Putin to avoid the politically costly second mobilization wave that destabilized his rule in late 2022, experts have said.

Despite the toll, Russian forces remain on the offensive across Donetsk and Zaporizhzhia and continue to fire massed missile-and-drone salvos at Ukrainian cities, with Moscow recently warning foreign diplomats to leave Kyiv ahead of what it called “systemic and sustained” strikes on decision-making centers.

But the trade is becoming visibly unfavorable.

Russia ground its way through more than a year of combat to capture Pokrovsk in late 2025, an advance the Center for Strategic and International Studies assessed was slower than Allied progress at the Battle of the Somme.

U.S. Secretary of State Marco Rubio said earlier this month that Russia is losing roughly five soldiers for every Ukrainian casualty — a ratio that, if accurate, suggests the Kremlin is paying far more per square mile of captured ground than during any earlier phase of the more than four-year war.

“The Ukrainian armed forces are the strongest, most powerful armed forces in all of Europe,” Rubio said earlier this month.

英国最高情报机构负责人周三表示，自 2022 年以来，已有近 50 万俄罗斯士兵在乌克兰丧生——这一死亡人数超过了二战期间美国的总伤亡人数。这是迄今为止西方政府对俄罗斯在乌克兰战争中造成的最高死亡人数之一。

据乌克兰总参谋部称，俄罗斯目前在前线每天约有 1000 名士兵伤亡。

西方官员逐渐达成共识，认为乌克兰多年来首次在战场上取得了重大优势，因为俄罗斯难以突破乌克兰的多层防空系统，也难以抵挡基辅日益增长的武器库和不断加强的反攻。

英国政府通信总部（GCHQ）情报主管安妮·基斯特-巴特勒周三表示：“（俄罗斯总统弗拉基米尔·）普京在战场上节节败退，新的情报显示，自冲突开始以来，已有近50万俄罗斯士兵丧生。”

到目前为止，西方各国政府对俄罗斯的总损失一直持保留态度，仅表示到 2025 年底，伤亡总人数约为 120 万人。

新的数字改变了这一局面：如果近 50 万俄罗斯士兵死亡，那么几乎可以肯定还有数十万人受伤——而莫斯科的实际伤亡成本要高得多。

这一披露进一步巩固了人们日益增长的共识：自战争爆发以来，俄罗斯首次处于被动局面。

战争研究所本周得出结论，随着乌克兰军队开始摆脱自 2023 年以来一直困扰前线的阵地战，俄罗斯在战场上的战果“接近净零”。此前，俄罗斯在 4 月份失去了 116 平方公里的乌克兰领土，这是 20 个月以来的首次净领土损失。

“鉴于其来源，这现在应该被视为官方估计，”皇家联合军种研究所前总干事迈克尔·克拉克告诉哥伦比亚广播公司新闻。

克拉克说，实际伤亡“很可能更高”，因为俄罗斯军队“对前线伤员漠不关心”。

这一数字与荷兰军事情报部门早前的一项评估大致相符，该评估认为俄罗斯的“永久性损失”约为 120 万人，其中包括 50 多万人死亡。

据 Meduza 报道，俄罗斯独立调查人员记录的最低数字远高于此：通过公开来源的报道，有超过 108,000 名俄罗斯战争死者被单独点名，据推断，最低数字约为 350,000。

美国情报机构尚未公开认可其自身对俄罗斯伤亡人数的具体估计，但国家情报总监办公室在 2025 年 3 月评估认为，俄罗斯已有超过 75 万人伤亡。

英国的最新估计（仅包括死亡人数）表明，俄罗斯的伤亡总数现在远远高于美国的任何一项评估。

乌克兰总参谋部公布的俄罗斯累计伤亡人数更高，约为136万人伤亡。

据英国情报部门称，在一次更广泛的讨论中，提到了俄罗斯针对英国的混合行动，包括对关键基础设施的网络攻击、破坏企图以及向莫斯科国防工业走私西方技术的努力，其中提到了俄罗斯的伤亡人数。

基斯特-巴特勒表示，英国政府通信总部“正与情报和国防伙伴不懈努力，以削弱和减少俄罗斯的威胁”。

专家表示，目前莫斯科正通过一套以现金签约奖金、战俘征兵和朝鲜军队分批从平壤派遣到前线支援的征兵机制来弥补这些损失，这使得普京能够避免在2022年底引发政治代价高昂的第二次动员浪潮，那次浪潮动摇了他的统治。

尽管伤亡惨重，俄罗斯军队仍在顿涅茨克和扎波罗热发动攻势，并继续向乌克兰城市发射大量导弹和无人机。莫斯科最近警告外国外交官离开基辅，因为俄罗斯将对决策中心发动所谓的“系统性和持续性”打击。

但这种贸易形势正变得明显不利。

俄罗斯经过一年多的艰苦战斗，于 2025 年末攻占了波克罗夫斯克。战略与国际研究中心评估认为，俄罗斯的推进速度比盟军在索姆河战役中的进展速度还要慢。

美国国务卿马可·卢比奥本月早些时候表示，俄罗斯每伤亡一名乌克兰士兵，就会损失大约五名俄罗斯士兵——如果这一比例准确，则表明克里姆林宫为每平方英里占领的土地付出的代价，比这场持续四年多的战争的任何早期阶段都要高得多。

“乌克兰武装部队是全欧洲最强大、最有实力的武装部队，”鲁比奥本月早些时候表示。
