Sukhoi Su-75 Checkmate
Russian fighter plane
The Sukhoi Su-75 Checkmate (Russian: Сухой Су-75), also designated as the Light Tactical Aircraft (LTA; Russian: Лёгкий Тактический Самолёт - ЛТС, romanized: Lyogkiy Takticheskiy Samolyot - LTS), is a single-engine, stealth fighter aircraft under development by Sukhoi for export and for the Russian Aerospace Forces. The Sukhoi Design Bureau also designates the aircraft as T-75.
Development
A static non-flying prototype was unveiled at the 2021 MAKS air show with President of Russia Vladimir Putin in attendance. The Checkmate's maiden flight was first scheduled for 2023, then delayed to 2024, and again to 2025; with initial deliveries planned for 2026 – 2027. The Checkmate is designed to be low cost for exports, and competes with the Lockheed Martin F-35A Lightning II and Shenyang J-35AE aircraft of the same light to medium-weight category. Production is forecast for 300 planes over 15 years.
According to the chief executive of Rostec, Sergei Chemezov, the LTS Checkmates are expected to cost US $25–30 million each.
Su-75 Checkmate development was delayed due to international sanctions on Russia caused by the Russo-Ukrainian war, whereby Russia could not import semiconductors and high-tech machining equipment from the European Union. The potential export sales also stalled because Russia cannot trade using U.S. dollars.
According to the Center for Security Policy's Maya Carlin in May 2023, sanctions from the war "crippled" the aircraft's development.
This brief starts where responsible research should: with the source description of “Sukhoi Su-75 Checkmate” as russian fighter plane. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as russian fighter plane. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q107594447. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021, 2023, 2024 and 2025.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
