Design: Semyon Alexseyevich Lavochkin, Vladmir Petrovich Gorbunov and Mikhail Ivanovich Gudkov
Manufacturer: State Industries; Type: Single Seat Fighter
Powerplant: One 1,240 hp (925 kw) Klimov M-105PF Vee 12-cylinder piston engine.
Performance: Maximum speed 348 mph (560 km/h) at 16,405 ft (5000 m); service ceiling 31,495 ft (9600 m).
Range: 404 miles (650 km) on internal fuel.
Weight: Empty 5,776 lbs (2620 kg) with a maximum take-off weight of 7,231 lbs (3280 kg).
Dimensions: Span 32 ft 1 3/4 in (9.80 m); length 29 ft 2 1/2 in (8.90 m); height 8 ft 10 in (2.69 m); wing area 188.37 sq ft
(17.50 sq m).
Armament: One 20 mm ShVak cannon firing through the propeller nose and two 2.7 mm (0.50 in) BS Machine guns
plus underwing racks capable of either two 220 lbs (100 kg) bombs or six RS-82 rockets.
Variants: LaGG-3 (developed from the short lived LaGG-1). Later versions had a retractable tailwheel and support for
drop tanks.
Operators: Soviet Union.

The generation of combat aircraft built in the Soviet Union during
the war witnessed the debut of designers who were to become world
famous over the next few years. Following Mikoyan and Gurevich,
another extremely talented technician was Semyon Alexseyevich
Lavochkin, whose initials characterized a family of fighters that
survived until the 1950s, ranging from the LaGG-1 of 1940, to the La-
11 of 1947, the last aircraft powered by a piston engine to serve in the
Soviet air force.
Lavochkin executed his first project together with another two
talented technicians, Viadimir Petrovich Gorbunov and Mikhail
lvanovich Gudkov, with whom he had worked since 1938. This was a
single-seater fighter, initially designated I-22 and then LaGG-1; the
prototype made its maiden flight on March 30,1940. The aircraft was a
low-wing monoplane, carefully studied from an aerodynamic point of
view and fitted with completely retractable landing gear. A
predominant feature that made it unique among its kind, was its being
built entirely in wood, with the exception of the moving parts, which
were metal, and the fabric covering: the fuselage, empennage, and
wings had a supporting structure in wood onto which a covering of
diagonal strips of plywood was stuck using special resins. Its engine
was a large Klimov M-105 liquid-cooled V-12 that generated 1,050 hp
at takeoff.
However, flight tests proved to be unsatisfactory. Consequently,
before production got under way, numerous modifications were carried
out. These included the adoption of a more powerful and supercharged
version of the Klimov M-105 engine (the 1,240 hp (925 kw) M-105PF)
and of a three-bladed variable-pitch metal propeller, increased fuel tank
capacity, and the installation of slats on the leading edge of the wings.
The prototype was redesignated I-301 and, once tests had
been completed, the fighter went into production with the official
designation LaGG-3. However, its initial operative service (from
1941) brought to light some negative flight characteristics, for
example, a tendency to go into a spin following particularly tight
turns, making further research and testing necessary.
Once in service with the units, the LaGG-3 was widely used in
the early phases of the war against the Germans, especially on the
Finnish front, and its performance proved to be satisfactory.
However, the aircraft never possessed the characteristics of an
interceptor that had been planned in the original project. Never-
theless, it was used with success in bomber escort duty, ground
attack, and target attack against the least dangerous of the for-
midable German fighters, such as reconnaissance planes and
bombers. Moreover, the LaGG-3 proved to be extremely versatile
and reliable. Its typical armament included a 20 mm cannon that
fired through the propeller hub and two 12.7 mm machine guns,
while under the wings supports were planned for light bombs or
rockets. Up to August 1942, a total of 6,528 LaGG-3s came off the
assembly lines, a remarkable number considering the unexceptional
performance of the aircraft.
In the course of production numerous other experimental
prototypes were completed, built with the aim of improving the
aircraft's characteristics. Lavochkin, in particular, dedicated himself
to the task of perfecting it. Following a series of failed attempts,
success was achieved when a radically new engine became
available. This was the Shvetsov M.82 radial engine and, once it had
been fitted on the LaGG-3, it transformed it into a first-class aircraft,
the LaGG-5 of 1942, one of the best Soviet fighters of the entire war.
