Su-75 Checkmate falters as Russia's war in Ukraine drains resources

In recent years, Russia has attempted to develop the Su-75 Checkmate as an advanced fifth-generation fighter jet. The project was initially presented as a cost-effective alternative to American and Chinese aircraft, aiming to attract foreign buyers. However, the ongoing conflict in Ukraine has significantly impacted Russia's military expenditure and resource allocation. As the invasion has continued, the development of new military systems like the Checkmate has stalled due to severe funding and logistical challenges that stem from international sanctions imposed on Russia. Reports indicate that as of early 2025, advancements on the aircraft had progressed to final tests, but specific flight evaluations remain unaddressed. The Su-75 was unveiled to the public in a non-flying prototype at the MAKS air show in 2021, with expectations for its maiden flight set for 2023. This timeline has been frequently adjusted, reflecting delays typically associated with Russian defense projects, which often fail to meet deadlines. Analysis shows that despite claims of the Checkmate being a formidable contender against models like the F-35, its physical design is only partially stealthy, complicating its capability as an advanced military aircraft on par with its competitors. Additionally, the United Arab Emirates had initially shown interest in the Checkmate project but later pivoted to procure the F-35, indicating growing skepticism regarding the viability of the Russian jet. The abandonment by a potential buyer exemplifies broader doubts about the Checkmate's future operational and export potentials. In summary, until the Su-75 can demonstrate its effectiveness in operational conditions and achieve significant milestones in flight testing, many experts remain doubtful of its place in the modern military aviation landscape. The ongoing war has relegated many ambitious defense initiatives to the back burner, raising concerns about Russia's ability to innovate under pressure while facing international isolation and depleted military resources.
