The Lavochkin La-5 was born out of necessity during World War II, evolving from the underperforming LaGG-3, itself a descendant of the LaGG-1.
Designed by Semyon Lavochkin, the La-5 replaced the LaGG-3’s inline Klimov engine with the powerful Shvetsov ASh-82 radial engine, dramatically improving performance.
First flown in March 1942 and introduced in July 1942, the La-5 retained the wooden construction of its predecessors but featured a cut-down fuselage and improved cockpit visibility.
Technical Advancements
Armed with two 20 mm ShVAK cannons, the La-5 was capable of engaging German fighters like the Bf 109 and Fw 190 on equal terms.
The La-5FN variant introduced fuel injection and further aerodynamic refinements, making it one of the best Soviet fighters of the war.
Combat Performance
The La-5 played a pivotal role in major Eastern Front battles, including the Battle of Kursk and the Siege of Leningrad.
Its agility, speed, and firepower made it a favourite among Soviet pilots, including aces like Ivan Kozhedub, who flew the La-5 before transitioning to the La-7.
Production and Legacy
Over 9,900 La-5s were built, serving as the backbone of Soviet fighter aviation until replaced by the improved La-7.
The aircraft’s success helped restore Soviet air parity and marked a turning point in aerial combat against the Luftwaffe.
