V Lavochkin La-7 (rusko Лавочкин Ла-7) je bilo enosedežno sovjetsko lovsko letalo, ki ga je med 2. svetovno vojno razvil oblikovalski biro Lavochkin. To je bil razvoj in dopolnjevanje Lavochkin La-5, in zadnji v družini letal, ki se je začela z LaGG-1 leta 1938. Njegov prvi let je bil v začetku leta 1944 in je kasneje leta vstopil v službo pri sovjetskih letalskih silah. Češkoslovaško letalstvo je naslednje leto prejelo majhno sestavo la-7, sicer pa ni bila izvožena. Oborožen z dvema ali tremi 20 mm (0,8 in) topom, je imel vrhunsko hitrost 661 kilometrov na uro (411 mph). La-7 so njegovi piloti čutili, da je vsaj enak vsakemu nemškemu batno motornem lovu. Leta 1947 ga je sovjetsko letalstvo postopno ukinilo, vendar je služilo do leta 1950 pri češkoslovaškem letalstvo.

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.

Oborožitev

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.
