The Lavochkin La-250 "Anakonda" was a high-altitude interceptor aircraft prototype developed in the Soviet Union in the 1950s. Its nickname anaconda was "invented" during the flight test and referred to both the elongated body shape as well as the relatively critical flight characteristics of the machine.
By the mid-1950s, it became obvious that subsonic cannon-armed fighters such as the Yakovlev Yak-25 would be unable to intercept fast high-altitude targets like the upcoming generation of strategic jet bombers. As a result, in 1953 Lavochkin OKB proposed addition of an air-to-air missile system to the Berkut air-defense system. Tasked with defense of Moscow, the Berkut system consisted of a large network of radars and surface-to-air missile sites as well as ground-controlled interceptor aircraft. Lavochkin's proposed missile, the G-300 utilized a guidance system based on vacuum tubes and was so heavy (about 1,000 kg (2,200 lb)) that no fighter in the Soviet arsenal could carry it. Instead, a Tupolev Tu-4 bomber (Soviet version of the Boeing B-29 Superfortress) was modified to carry four G-300s under the wings, with the whole system receiving designation G-310. For all this trouble, G-300 was expected to have a range of only 15 kilometres (9.3 mi) and a ceiling of 20,000 metres (66,000 ft). Although G-310 made ten flights in 1952, the system was abandoned as impractical.
In November 1952, the Soviet government ordered development of Kompleks K-15 (Complex K-15, a notion analogous to USAF's "weapon system" concept). K-15 was to consist of an "interceptor 250" (later designated La-250) carrying "Type 275" guided missiles. La-250 had to be able to intercept targets flying at 1,250 km/h (780 mph), Mach 1.18) at 20,000 metres (66,000 ft) up to 500 kilometres (310 mi) from the airbase. Initial guidance was to be from Vozdukh-1 ground control with terminal onboard radar guidance for the last 40 kilometres (25 mi) and automatic missile firing by the fire control system when in range. Missile "275" was projected to weigh 870 kilograms (1,920 lb) and, powered by a liquid fuel rocket motor, its top speed was to exceed 3,900 km/h (2,400 mph). With a 125 kilograms (276 lb) conventional warhead, it had a projected lethal radius of 50 metres (160 ft). La-250 was to carry two "275" missiles semi-recessed into the underside of the fuselage in a tandem arrangement.
The first flight took place on 16 July 1956 by Andrei G. Kochetkov. Problems with the K-15U radar and Klimov VK-9 engines forced a radical redesign of the aircraft to use the K-15M radar and, more importantly, much less powerful Lyulka AL-7F engines. This, in turn, led to the need to change "275" missiles to the lighter "275A" (interestingly, although total missile weight decreased to 800 kilograms (1,800 lb), the warhead actually grew to 140 kilograms (310 lb). The new airframe with a smaller fuselage and a delta wing instead of the earlier swept wing was designated La-250A. The "275" missiles were now carried on underwing pylons. The lighter airframe was not enough to overcome the weaker engines, and projected performance suffered compared to La-250. While busy redesigning the aircraft, Lavochkin OKB also had to develop new variants of the "275" missile - the semi-active radar homing "277," the nuclear-armed "279," and solid fuel rocket-powered "280." The first La-250A prototype was finally rolled out on June 16, 1956.
Test flights of the five prototypes were plagued by crashes caused by failures of the hydraulic boost system and landing gear as well as poor forward visibility (the latter was corrected with fitting of a new slightly "drooped" nose). La-250A made a single test flight in 1956, only 6 flights in 1957, and a mere 14 flights in 1958. Frustrated by the lack of progress, Soviet Air Force stopped all work on the K-15 system in 1959. Lessons learned with K-15 were used to develop new interceptor system requirements which led to the Tupolev Tu-28 interceptor.
The abortive, trouble-filled development of La-250 was mirrored in the West by the similarly complicated creation of Convair's delta-winged F-102 Delta Dagger and F-106 Delta Dart interceptors, which however eventually resulted in operational weapon systems.

On the inside of this (see next 12 photos) is an amazing mural depicting (as I understand it) Mongolia's deep gratititude and endebtedness to the Soviet Union. Also, for sending them to space?
The Soviet War Memorial (Tiergarten) is one of several war memorials in Berlin, capital city of Germany, erected by the Soviet Union to commemorate its war dead, particularly the 80,000 soldiers of the Soviet Armed Forces who died during the Battle of Berlin in April and May 1945.
The memorial is located in the GroĂźer Tiergarten, a large public park to the west of the city centre, on the north side of the east-west StraĂźe des 17. Juni (17 June Street) in the Tiergarten locality.
Something new for my collection of Cold War stuff. Not sure how accurate it is, Czechoslovakian hat with a Soviet Red Star Badge.
Powerhouse Museum, Sydney
I am not sure what type of craft this is, but suspect it was from one of the Soyuz missions. If you know, please let me know
This memorial is located in the Tiergarten area of Berlin. When I took this in 1988, Berlin was still a divded city. This was the only area of West Berlin where Soviet troops were stationed.
