Tupolev Tu-144

"Konkordski", The world’s first SST.

Not known by many people, the Tupolev 144 was the world’s first supersonic transport aircraft (SST) just two months before Concorde. It was also the first SST to exceed Mach 2. Very similar in design to Concorde, allegations were often made that the Soviets had stolen Concords plans. In this article we will look into the history, and present status of this remarkable aircraft.

CCCP-77115 Tu-144D

During the 60s, the race was on between the West and the Soviet Union to develop a supersonic transport (SST). First to publish a SST study was Douglas in 1961. The US started a competition in 1964 to develop a SST. North America, Lockheed and Boeing competed. In 1967 Boeing was awarded a contract for two prototypes of the proposed model 2707. Only a wooden mock-up was build when the program was cancelled.

Meanwhile a Anglo-French consortium formed on September 1961 started the development of their own SST. The aircraft called Concorde was evolution of the Bristol 223 study. The 001 prototype construction started February 1965 with it’s roll out on 11 December 1967. It than took another 15 month before the first flight on 2 March 1969.

Like the West, the Soviets wanted a SST of their own. The plans were first published in 1962. Development of the Tu-144 started 26 July 1963 as a passenger version of the un-build Tu-135 supersonic bomber (called the Tu-135P). The canard layout, wings and nacelles were retained in the Tu-144 prototype.

The prototype called “044” was build in the MMZ factory in Moscow and assembled at Zhukovsky flight test center. First flight was on the last day of 1968, when test pilot Elyan made a test flight of 37 minutes. 6 months later the aircraft passed the Mach 1 marker, and on 26 May 1970 it was the first civil aircraft to reach Mach 2. During the test face, the first problems started to occur. The problems included severe vibrations and tail overheating due to the location of the engines. Only on the prototype the 4 engines were placed in one line, partly under the main fuselage. It was clear the design had to be changed.


The first pre-production aircraft, series “004” first flew 1 June 1971. The most noticeable change was the location of the engines. The engines, upgraded to the NK-144A model, were placed in pairs, next to the fuselage. This solved the heat and vibration problems. The wing surface was also increased to improve the aerodynamics. The fuselage was lengthened to support 150 passengers. Another improvement was the addition of two canard wings on the forward fuselage to increase stability on take-offs and landing.

Five Tu-144S preproduction aircraft were build. The last one, aircraft 03-1 was later the first Tu-144D model when she was re-engined in 1976.

Paris airshow crash

Actual footage of the first fatal accident during the 1973 Paris Air Show at Le Bourget.

The first fatal accident occurred during the 1973 Paris Air Show at Le Bourget. The second pre-production aircraft (CCCP-77102) was shown together with Concorde. this airframe was the first build in the VASO factory. It featured an further improved wing area and new wingtips were fitted.

On the last day of the show (3 June 1973), the Tu-144 performed a demo flight just after Concorde impressed the 250.000 spectators present. What happened during the display remains controversial to this day and is still undetermined.

After a low pass over the runway, the engines were pushed to full power, to climb to 1.200 meters. The aircraft went into a sudden dive, some suggested due to low quality fuel. When the crew tried to recover, the left wing broke off and the aircraft crashed in the village of Goussainville, killing all 6 crewmembers and 8 people on the ground.

Another theory is that the crew tried to avoid a Mirage 3, maneuvering into a steep dive, pushing the structural limits. The Mirage 3 was chasing the Tu-144 to photograph it’s canards, state of the art during that time. The presence of the Mirage was denied in the early investigation reports, but was later admitted.

Until this day, the real reason for this crash remains undetermined.

Operational service

The first Tu-144S went into service on 26 December 1975, flying mail and freight between Moscow and Alma-Ata. The first passenger services not started until November 1977. The S model was extremely unreliable. During the 102 flights it suffered 225 failures, 80 of them inflight. During 1976 a pre-production Tu-144S was converted to Tu-144D model “044D”. The aircraft were fitted with new Kolesov RD-36-51 turbojet engines. This provided an increase in cruise speed, similar to the Concorde and improved range of 6.500 km.

Soviet leadership decided the Tu-144 had to enter passenger service in 1977 even when reports the aircraft was not airworthy for regular service. Another problem was the high levels of noise during the flight. Passengers sitting next to each other couldn’t have a normal conversation. The noise came partly from the engines, and also from the fuselage cooling system. The noise in the back of the plane was unbearable.

Another accident in 1978 marked the end of the passenger service. D model CCCP-77111 crash landed at Yegoryevsk, losing the whole plane in the following fire. Combined with the economical situation and high oil prices the days of operational service were numbered.

The Tu-144 program was cancelled by the Soviet government of 1 July 1983. Remaining aircraft were used as airborne laboratories. From 1985 until 1988 the aircraft were used to train Buran pilots and perform medical and biological research.

NASA involvement

In 1995, Tu-144D (CCCP-77114) was taken out of storage and converted at a cost of 350M US dollars. This aircraft designated Tu-144LL was later re-registered RA-77114. One of the improvements was the use of the Kuznetsov NK-321 engines, also fitted to the Tu-160 bomber. Tupolev, Rockwell, NASA and other US companies joined forces and used the Tu-144LL as a testbed for its high speed commercial research program.

A total of 27 flights were made between 1996 and 1997. Although a technical success, the program was cancelled in 1999 due to lack of funds. The aircraft is until this day stored a Zhukovsky.

09-2 CCCP-77116 Tu-144D Never flew. Probably stored at VASO factory. Work on this aircraft stopped in 1985 when the program was cancelled.

Military use

During the course of the Tu-144 project, Tupolev designed a number of military versions, of which none was ever build. The Tu-144R was developed to carry up to three solid fuel ICBMs. This version was initially based on the Tu-144S, later changed to the Tu-114D. Plans for an air launched ICBM were dropped and a version was designed to carry the Kh-55 cruise missile. In the late 70s a study was made to develop a long-range interceptor. This project later evolved into an ECM aircraft called the Tu-144PP. In the early 80s an reconnaissance version was proposed, the Tu-144PR. The last proposed military version was the Tu-144MR, a long range reconnaissance version for the Navy.

I'm not entirely sure, but i think the wingtip modification is not related to the model designation. The D models had the changed wing directly from build and some S models were probably retrofitted. Main difference between the S and D model were the changed engines and landing gear configuration.

Hi - I was just wondering if you could help me work out the differences between the different models and their dimensions in relation to a page written in tu144sst.html :

As you can see they have split the production aircraft between as 'Series Aircraft' and 'Series Aircraft with wingtips' with a list of the different aircraft identified by their registration number which fall into each category. The dimensions for the 'Series Aircraft with Wingtips' seems to more closely correspond with the 144D, looking at the wingspan and the wing area. This is despite the fact the 144D list includes a number of registrations that are 144S', such as 77102, 77103, 77105 etc...

I also noticed that in your note for the 77102 that you say the plane has 'Improved wing area and wing tips.' I was just wondering what you make of this information, and why certain planes are in their respective lists, being a mix of 144S's and 144D's?

Any help with this would be greatly appreciated!
