The La-7 was a further enhancement of the La-5FN aircraft. Although there were only slight differences in size and silhouette between the La-7 and the La-5, the La-7 had one essential structural distinction: wing spars made of metal (as on the most recent La-5FN series). Ribs and paneling were left unchanged. Spar size was considerably diminished to free up additional space for the fuel tanks. Spar weight was reduced to approximately 100 kg . Aircraft aerodynamics was also considerably improved through the transfer and improvement of the radiator's aerodynamic forms ( this feature distinguishes the La-7 from the La-5 on the outside ). All these improvements gave the La-7 the edge over the La-5 in speed, rate of climb and service ceiling. The armament could consist of either 2 ShVAK cannons or 3 B-20 cannons of 20mm caliber. Some 5,735 La-7s were produced up until the end of the Second World War.

Advantages: One of the best serial front-line fighters of the end of the war with excellent flight performance. Improved aerodynamics. High maneuverability and strong armament. Absolute combat superiority over most of the lastest piston-engined German, English and American fighters at low and medium altitude. Increased aircraft durability. Simple and easily teachable controls.

Disadvantages: The culture of production was slightly inferior than that of "Yak" fighters of the end of the war and it was necessary to ensure weight reduction for wooden parts of the glider. As a result, the all-metal La-9 aircraft was created.
