Su 27 Ukraine

The Sukhoi Su-27, often nicknamed “Fulcrum,” has played a pivotal, though complex, role throughout the Ukraine War (2022-present), primarily through Ukrainian Air Force and Navy operations. While initially optimistic about its continued deployment, the Su-27’s operational status has significantly diminished due to sustained Russian air defenses and attrition.

Following Russia's invasion in February 2022, Ukrainian pilots immediately began utilizing the remaining Su-27 fleet – primarily from the 64th Fighter Regiment based at Starikove and the 57th ‘Bayraktar’ Naval Aviation Brigade operating from Yevpatoria – to engage Russian ground forces and air targets. Initial reports indicated successful strikes against armored vehicles, including T-72s and BMP-3s, with several confirmed losses on both sides. Specifically, early in the conflict, Ukrainian sources reported at least three Su-27s were lost due to Russian missile attacks, primarily utilizing S-300 systems targeting air defense assets like Buk-M1 SAMMs (September 2022).

**Attrition & Shift in Role (May 2022 – Present)**

As the war progressed and Russia intensified its air defenses with advanced systems such as the S-400, Ukrainian Su-27 operations became increasingly risky. The aircraft’s vulnerability to modern Russian missiles led to a significant attrition rate. By late 2022, only approximately 15-20 operational Su-27s remained in service, largely relegated to defensive roles—primarily providing air cover for coastal defenses and engaging low-value targets – due to the increased risk of combat losses. Maintenance has become extraordinarily challenging given supply chain disruptions and constant threat of attack. As of early 2024, Ukraine is actively seeking replacements but faces significant logistical and financial hurdles in acquiring newer aircraft. The final Su-27 was reportedly lost on January 18th, 2024, during a reconnaissance mission over the Black Sea.
