| The Lavochkin bureau's response to Yosif Stalin's order
of February 1945 to design and build a single-seat jet
fighter around a Junkers Jumo 004B turbojet, the
La-150 was of distinctive pod-and-boom layout with a
shoulder-mounted wing. Like the competitive designs
from the Mikoyan-Gurevich and Yakovlev bureaux, the
La-150 was awarded a prototype/pre-series aircraft
order, the first of the prototypes flying in September
1946 powered by the Soviet derivative of the Jumo
engine, the RD-10 rated at 900kg. Unique
among first-generation Soviet jet fighters in having a
fuselage-mounted undercarriage, the La-150 featured a
somewhat complex, overly robust and heavy structure
and was, in consequence, underpowered. Excessive
dihedral effect resulting from the wing positioning was
rectified on the second prototype by drooping the wingtips,
but excessive oscillation of the tail surfaces at high
speeds resulting from inadequate stiffness of the tailboom
could not be overcome. In the event, only five airframes
were completed. Armament comprised two 23mm NS-23 cannon.
