Riik	Nõukogude Liit
Tüüp	Fighter
Esimene lend	1. veebruar 1944
Ehitatud	5800+

2007 Lavochkin La-7 (vene keeles Лавочкин Ла-7) oli kolvimootoriga nõukogude hävituslennuk, mille töötas teise maailmasõja ajal välja Lavotškini disainibüroo. See oli Lavochkin La-5 arendamine ja täiustamine ning viimane lennukiperes, mis algas LaGG-1-ga 1938. aastal. Selle esimene lend toimus 1944. aasta alguses ja see asus teenistusse Nõukogude õhujõududes hiljem samal aastal. Järgmisel aastal anti Tšehhoslovakkia õhujõududele väike partii La-7-sid, kuid muidu seda ei eksporditud. Relvastatud kahe või kolme 20 mm (0,8 tolli) kahuriga, oli selle tippkiirus 661 kilomeetrit tunnis (411 miili tunnis). La-7 oli tema pilootide arvates vähemalt võrdne mis tahes Saksa kolvimootoriga võitlejaga. See kaotati järk-järgult 1947. aastal Nõukogude õhujõudude poolt, kuid teenis kuni 1950. aastani Tšehhoslovakkia õhujõududes.

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.

Armament

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.
