Första flygningen	Den 1 februari 1944
Byggd	5800+

Den Lavochkin La-7 (ryska: Лавочкин Ла-7) var ett ensitsigt sovjetiskt stridsflygplan utvecklat under andra världskriget av Lavochkin Design Bureau. Det var en utveckling och förfining av Lavochkin La-5, och den sista i en familj av flygplan som hade börjat med LaGG-1 1938. Dess första flygning var i början av 1944 och den togs i tjänst med det sovjetiska flygvapnet senare under året. Ett litet parti La-7:a gavs till det tjeckoslovakiska flygvapnet följande år, men det exporterades i övrigt inte. Beväpnad med två eller tre 20 mm kanoner hade den en topphastighet på 661 kilometer i timmen. La-7 ansågs av sina piloter vara minst lika med alla tyska kolvmotoriga jaktplan. Det avvecklades 1947 av det sovjetiska flygvapnet, men tjänstgjorde fram till 1950 med det tjeckoslovakiska flygvapnet.

General Characteristics

The Lavochkin La-7 was a Soviet piston-engined, single-seat fighter aircraft developed late in World War II. As the ultimate refinement of the La-5 series, the La-7 introduced significant aerodynamic improvements and the replacement of some wooden parts with aluminum, resulting in better overall performance and reduced weight. It was regarded by many Soviet pilots, including the top Allied ace Ivan Kozhedub, as the equal of any German piston-engined fighter at low to medium altitudes, excelling as an air superiority fighter and interceptor on the Eastern Front.

Powerplant and Performance

Engine: One Shvetsov ASh-82FN 14-cylinder air-cooled radial engine.
Power Output: 1,380 kW (1,850 hp).
Maximum Speed: 661 km/h (411 mph) at 6,000 m (19,700 ft). Some prototypes reached 680 km/h.
Maximum Speed (Sea Level): 597 km/h (371 mph).
Service Ceiling: 10,450 m (34,280 ft).
Rate of Climb: Approx. 15.7 m/s (3,095 ft/min).
Key Improvement: Aerodynamic refinements included moving the oil cooler from the nose to under the fuselage and relocating the engine air intake to the wing roots.

Beväpning

Standard Armament: 2 x 20 mm ShVAK cannons (with 200 rounds per gun), firing through the propeller arc.
Alternate Armament: Later production runs were armed with 3 x 20 mm Berezin B-20 cannons (with 100 rounds per gun), which were lighter and improved firepower.
Suspended Ordnance: Up to 200 kg (440 lb) of bombs on two underwing hardpoints (typically 50 kg or 100 kg bombs).
Pilot Feedback: Pilots praised the concentration of fire from the nose-mounted cannons, though the standard ShVAK guns were sometimes criticized for having less effective damage than comparable German weapons.
