20k La-174TK on snow covered airfield form The
Jet Genesis
Experimental fighter,
development of the La-156
with thin non-swept wing (TK stays for Tonkoe Krylo, Thin
Wing).
More powerful engine (1*1590kg NII-1) was installed.
Trials in early 1948 proved that straight wing has no chances to compete
with swept one at high flight speeds. All steed against the La-156
was gained due to new powerplant. La-174TK was the last straight-wing aircraft
of S.A.Lavochkin team.
One built.
