La-156 (Type 5) by S.A.Lavochkin

12k picture from The Jet Genesis

Rebuilt La-152 to accommodate more powerful version of RD-10F with afterburning thrust 1350kg. Fuel capacity was increased, as well as wing and tail surfaces. Intended as a front line fighter.

First tests (pilots S.F.Mashkovskij and I.E.Fedorov) took place in February-March 1947. State trials in the NII VVS during September 5, 1947 - January 31, 1948. La-156 speed exceeded 900km/h. But it was also obvious that straight wing stays on the way of faster aircraft.

S.A.Lavochkin already was working on swept-wing La-160. At the same time the La-174TK became the last attempt to improve straight-wing design by employing very thin wing airfoil.
