Lavochkin La-250

Destined to be the last aircraft produced by the Lavochkin design bureau, the La-250, known unofficially as the Anaconda, was designed to meet a very demanding 1954 requirement for an ultra long-range, high-altitude single-seat super interceptor armed exclusively with missiles. Featuring a 57 delta wing and an enormous fuselage of near-constant cross section, the La-250 was powered by two Lyulka AL-7F turbojets each rated at 6500kg which were later to be fitted with afterburners boosting thrust to 9000kg. All control surfaces were fully powered with duplex systems and without manual reversion. Intended to carry the 30km acquisition- range Uragan (Hurricane) radar, the La-250 had a planned armament of two large K-15 beam-riding missiles.

Although the La-250 was intended as a single-seater in operational form, prototypes were completed as two-seaters to provide accommodation for a test observer, and the first of three flying examples was completed in July 1956. The first flight was attempted on 16 July, but the test pilot, A G Kochetkov, encountered an unexpectedly rapid roll moment and lost control. Extensive testing of a systems rig followed before acceptable characteristics were attained and flight testing could be resumed. The second aircraft was lost in a landing accident on 28 November 1957, and the third aircraft also suffered a landing accident on 8 September 1958. The flight test programme suffered continual delays as a result of poor engine reliability and the full testing had not been completed when the programme was cancelled.

In russia sukhoi and mikoyan were compotate to make fighter they are the expert for this one and also yakovlev,the tupolev is expert in bomber and antonov in transport aircraft,mil and kamov in helicopter,and beriev expert in flying boat.
Thats company also built transport and civil aircraft only lavochkin who doesen't built transport and civil aircraft.

In russia sukhoi and mikoyan were compotate to make fighter they are the expert for this one and also yakovlev,the tupolev is expert in bomber and antonov in giant aircraft,mil and kamov in helicopter,and beriev expert in flying boat.

@ Sg.KAR98 It was in sovietunion that the Goverment set the spetification then usualy about 4 OKB sendet theyer project drawings. 2 of them get the go a head to build 1 or a few prototyps. The Goverment and the Air Force then testet teh Prototyps and choosed one for producion. in the Soviet Union the Factoris are not part of the OKB so if Yakovlev win the contest the factory build Yaks, if Sukhoi wins the buils Sukhois

They did not.

If you look at the producers and designers, you will see that in USSR the producers were many (many factories in various places) but the designers were a few only. And for fighters do not forget Tupolev and Yakovlev.

Maybe because Sukhoi and Mikoyan-Gurevich made better fighters?

Sg.KAR98, 08.03.2008

If Soviet Union had a different mind from capitalism,why only Sukhoi and Mikoyan Gurevich produced fighters in that time?

Do you have any comments about this aircraft ?

FACTS AND FIGURES

The third La-250 had its nose lowered by six degrees to give better visibility on landing, the poor view forward having been determined as a factor in the second crash.

Intended as a single-seater, the prototypes had a second seat for a flight test engineer.

Intended armament was a pair of K-15 missiles that rode the beam of the Uragan radar, which had a range of 30km.

The missiles were cancelled and the radar never made it into an aircraft before the development was cut short.
