Key Points and Summary – In a fascinating post-Cold War tale of intelligence acquisition, the United States privately purchased two advanced, two-seat Su-27UB “Flanker” fighter jets from Ukraine in the mid-2000s.
-The transaction was handled by a private American company, Pride Aircraft, which then sold the jets, allowing them to disappear from public view in 2011.
-It is widely believed the aircraft were acquired by the U.S. government for its Foreign Material Exploitation (FME) program, where they were likely studied and flown at classified sites like Area 51 for adversary training.
-In 2023, one of the jets resurfaced and is now on display at the National Museum of the U.S. Air Force.
The Secret Story of the Su-27 Flankers That Vanished and Ended Up In America
If you ever get the opportunity to visit the U.S. Air force Museum in Dayton Ohio, you will likely see a lone Soviet made Sukhoi Su-27 Flanker on display.
Anyone familiar with Soviet aviation history is probably aware that the USSR was intensely paranoid about selling Su-27 fighters to anyone, even allied nations. So, how in the world did a Su-27 manage to make its way over to the United States?
Actually, two Flankers were sold in the U.S., one of them remains on display at the museum while the other is likely in a testing facility somewhere in the country.
From Ukraine to the Heartland of America
The Su-27, known in NATO terminology as the “Flanker,” was developed by the Soviet Union in the 1970s and 1980s to counter American fourth-generation fighters such as the F-15 Eagle and the F-14 Tomcat. It was a technological marvel, boasting exceptional maneuverability, long-range capabilities, and a powerful suite of avionics and weapons. The aircraft quickly became a symbol of Soviet air power and was exported to sever allied nations only after the Cold War had ended.
In the mid-2000s, a U.S.-based company called Pride Aircraft, located in Rockford, Illinois, managed to acquire two Su-27UB aircraft from Ukraine. These were two-seat trainer variants of the Su-27, and they were legally purchased through open-market channels.
Ukraine, facing economic difficulties and reducing its military inventory, was selling off surplus equipment. Pride Aircraft seized the opportunity and bought the jets for approximately five million dollars each—a fraction of their original cost.
The USSR’s Best Fighters are in America
Once the aircraft were purchased, they were shipped to the United States aboard Antonov An-124 cargo planes. Upon arrival, they were reassembled, inspected, and fitted with freshly overhauled engines. The jets were then registered with the Federal Aviation Administration (FAA) under the designations N131SU and N132SU. They retained their original Ukrainian Air Force camouflage and Soviet-style markings, which made them particularly striking to aviation enthusiasts.
Pride Aircraft marketed the Su-27s as the most advanced warbirds ever available to private collectors in the United States. Their appearance generated significant buzz in the aviation community, as it was virtually unheard of for such advanced former Soviet military hardware to be legally owned by a private American company.
The Su-27 Drops off the Radar
However, the story took a mysterious turn in 2011 when Pride Aircraft quietly updated its website to indicate that both Su-27s had been sold. No public buyer was identified, and the aircraft disappeared from public view. They were officially registered to a Delaware-based company called Meridican, Inc., but this entity appeared to be a shell company with no public-facing operations. This sudden disappearance led to widespread speculation in various circles.
There have been a number of conspiracy theories that spawned from this ordeal. Many believed that the U.S. government had quietly acquired the jets for use in its Foreign Material Exploitation (FME) program.
FME is a long-standing initiative in which the U.S. military obtains and studies foreign military equipment, especially from adversaries, to better understand their capabilities, develop countermeasures, and train American forces.
The U.S. has a history of operating foreign aircraft in secrecy, including MiG-21s and MiG-29s, under programs like “Constant Peg.”
What Happened to the Flankers?
It is widely believed that the Su-27s were taken to a classified facility such as Groom Lake, more commonly known as Area 51, for evaluation.
There, they would have been used for dissimilar air combat training, radar and sensor testing, and electronic warfare exercises.
These activities would have provided invaluable insights into the performance and vulnerabilities of one of Russia’s most capable fighter jets.
The Su-27s would have been especially useful for training U.S. pilots to fight against aircraft with different flight characteristics, helping them develop effective air combat tactics. Engineers could also reverse-engineer components to understand the aircraft’s radar, avionics, and flight control systems.
Additionally, testing American jamming and spoofing systems against real Russian hardware would have been critical for modern electronic warfare.
Some argue that this was all an elaborate ploy by the U.S. to acquire Su-27s from Ukraine without raising alarm bells from Russia. Since Ukraine was the original owner of the aircraft, it had the right to sell them.
The U.S. government did not directly purchase the jets from Ukraine, which could have raised diplomatic concerns with Russia. Instead, the use of a private intermediary like Pride Aircraft provided plausible deniability and avoided international controversy.
“Blue 32” Finally Reappears
In 2023, more than a decade after their disappearance, one of the jets, N132SU (also known as “Blue 32”) resurfaced at the National Museum of the U.S. Air Force in Dayton, Ohio. The museum announced the acquisition on social media, confirming that the aircraft was now part of its collection.
It was displayed in excellent condition, still wearing its original camouflage and markings. This public display effectively confirmed what many had long suspected: the aircraft had been in U.S. government hands for years, likely undergoing extensive evaluation and testing.
Currently, Blue 32 is located at the U.S. Air Force Museum in Dayton, Ohio, where the public can visit and see it for themselves. The second Su-27 is still unaccounted for, likely still at whatever testing facility they were sent to.
The reappearance of the Su-27 at a public museum offered a rare glimpse into the shadowy world of foreign aircraft exploitation.
It is an odd but also fascinating story of the slightly shady measures taken that finally allowed the U.S. to see the inner workings of one of the Soviet’s finest aircraft ever produced.
