Version overview:
La-126
- prototype all-metal fighter aircraft with a laminar wing profile, was used for the La-130R / La-9
La-130 / La-9
- The all-metal construction of the aircraft allowed for increased range and armament
La-9 UTI
- two-seat trainer version
La-130 R
- unfinished prototype, combination of AS-83 piston engine and RD-1CH3 rocket engine in the rear fuselage
La-138
- prototype, tests, two VRD-430 thrust engines suspended under the wings
La-9 RD
- prototype, tests, two RD-13 pulse engines suspended under the wings
La-134
- prototype, reduced number of guns to 3, increased fuel tank capacity, pattern for production La - 11
La-134d
- Prototype (also known as La-9M), fixed fuel tanks of 332 litres installed on the wing tips
La-140 / La-11
- Improved airframe aerodynamics, increased range, aircraft intervened in Korean War
Lavochkin La-9 / La-11 ... important data
- February 1946 ...... take-off of the prototype " 130 " ( La - 9 )
- June 1946 ... admitted to state tests
- August 1946 ..... first serial La - 9
- May 1947 ... take-off of prototype " 134 " ( predecessor of 140 / La - 11 )
- September 1947 ....... tests of the prototype La - 9 RD
- October 1947 ...... first serial La - 11
- April 1948 .... first serial La - 9 UTI
- May 7, 1948 ... 3 La-11 and 1 Tu-6 land near the North Pole. Several takeoffs and landings demonstrate the La - 11's ability to deploy in these conditions ( operating there for two days ).
- 1950 ... China acquires La-11 from the USSR ( unknown quantity )
- 1950 ... North Korea acquires both the La-9 and La-11 from the USSR
- April 2, 1950 ... two Chinese La-11s shoot down two Taiwanese P-51 Mustangs ( piloted by Soviet advisors )
