Steadfast: Soviet Design Meets American Muscle

Easily one of the most dynamic air display platforms in the Southern Hemisphere, the Yakovlev Yak-3U Steadfast combines the finest evolution of Soviet-era airframe design with the brute force of American engineering. Power comes from a Pratt & Whitney R-2000 Twin Wasp engine—an impressive marriage of performance and reliability that makes Steadfast a true showstopper.

Owned by Omaka-based pilots Mark O’Sullivan and Scott Madsen, Steadfast has a remarkable pedigree. Originally campaigned at the Reno Air Races in 2006, it went on to claim nine world records, including the under-3000 kg World Speed Record at 416 mph (669 km/h), as well as several “time to climb” records.

Beyond its speed, Steadfast is also one of a small number of piston aircraft equipped with the Sanders smoke generator system, creating dramatic trails from each wingtip. As the aircraft dances through the air, these perfectly parallel “railway tracks” of smoke twist and curl into ever-changing patterns—turning the sky into a canvas of motion and precision.

Steadfast first appeared at Classic Fighters in 2017, when organisers arranged to bring the aircraft to Omaka for the show. It quickly became the standout star of the event before returning overseas. When it later came onto the market, Mark seized the opportunity to bring it back to Marlborough permanently. Since then, local aviation fans have been treated to regular practice displays that never fail to draw attention.

At present, Steadfast’s R-2000 engine is undergoing a major overhaul in the United States. It will return to Omaka well ahead of Classic Fighters 2027, ready to take to the skies once more. Spectators can look forward to the unmistakable sound and power of this extraordinary warbird—a true highlight of any flying display.
