A Russian Su-30SM multirole fighter jet has likely crashed in the Black Sea southeast of Zmiinyi (Snake) Island (Odesa Oblast), according to the Ukrainian Navy.

Naval intelligence intercepted radio communications indicating the loss of contact with the aircraft during a mission. The cause of the incident remains unknown.

Russian forces have launched a search-and-rescue operation; debris has been spotted on the sea surface, but the pilot has not been found.

Why this loss matters for Russia’s air force

The Su-30SM is one of the Russian military’s most capable 4th-generation fighters, used for air superiority, long-range patrols, escort missions, radar surveillance, and command-and-control.

FlightGlobal’s 2025 world air forces directory lists 365 Su-27/30/35 fighters in Russian service (exact Su-30SM numbers are not public). Each Su-30SM is estimated to cost between $35 million and $50 million, making every loss a major hit to Russia’s high-value combat fleet.

The aircraft has been used extensively in the war against Ukraine, including for the launch of Kh-31P and Kh-58 anti-radiation missiles aimed at suppressing Ukrainian air defenses.

Documented Su-30SM losses since 2022

Ukraine has reported multiple Su-30SM shootdowns and ground destructions since the full-scale invasion began:

• Feb–Mar 2022: Several Su-30SMs downed over the Black Sea, Odesa, Kyiv, Kharkiv, and Mykolaiv regions — some crashed into the sea, and in one case a pilot was captured.
• Aug 9, 2022 — Saky/Novofedorivka, Crimea: Satellite imagery confirmed 8–9 aircraft destroyed, including around three Su-30SMs.
• Sept 2024 — Black Sea: Ukraine reported downing a Su-30SM that had just fired a Kh-31P missile.
• Apr 24, 2025 — Rostov-on-Don: Ukraine’s military intelligence (HUR) released video showing a Su-30SM (tail “35”) burning after a sabotage attack.
• Aug 4, 2025 — Saky airbase, Crimea: The Security Service of Ukraine (SBU) said one Su-30SM was destroyed and another damaged, alongside strikes on Su-24s and an ammunition depot.
• May 2, 2025 — Novorossiysk (claim): Ukraine claims naval drones armed with air-to-air missiles downed two Su-30s over the Black Sea — independent verification is pending.
• Aug 14, 2025 — Zmiinyi (Snake) Island area: The latest suspected Su-30SM loss.

Strategic шmplications

The possible downing of another Su-30SM underscores Ukraine’s ability to inflict attrition on Russia’s front-line combat aviation. With high unit costs and a shrinking pool of trained aircrews, each loss erodes Russia’s air combat capability — particularly in contested zones like the Black Sea.
