俄罗斯尚未在乌克兰使用其先进的T-14型坦克或Su-57型喷气式飞机, Russia hasn't used its advanced T-14 tanks or Su-57 jets in Ukraine, opting for older models due to cost, risk, and supply issues.

联合王国军方期待俄罗斯在乌克兰部署T-14 Armata型坦克和Su-57型战斗机等先进系统,但很少看到这些高端平台没有使用。 The UK military expected Russia to deploy advanced systems like the T-14 Armata tank and Su-57 fighter jets in Ukraine but has seen little to no use of these high-end platforms. T-14没有进入战斗, 俄罗斯则依赖旧坦克, 例如T-90和T-80。 Despite their $5 million to $9 million price tag and Russian state media hype, the T-14 has not entered combat, with Russia instead relying on older tanks such as the T-90 and T-80. 分析家认为这种克制是由于担心失去宝贵的资产、维修费用高以及先进设备容易落入无人机和地雷的手中。 Analysts attribute the restraint to concerns over losing valuable assets, high maintenance costs, and the vulnerability of advanced equipment to drones and mines. 苏-57战斗人员大多留在俄罗斯领空内,主要用于导弹打击。 The Su-57 fighters have largely stayed within Russian airspace, used mainly for missile strikes. 西方官员说,缺乏部署反映了在供应短缺和大量损失的情况下,从战略上将数量置于质量之上。 Western officials say the lack of deployment reflects strategic prioritization of quantity over quality amid supply shortages and heavy losses.
