On August 30, 1987 the Israeli government by a vote of 12-11 decided to cancel the Lavi fighter aircraft project. The Lavi was the best fighter aircraft in the world at the time, the result of the work of thousands of engineers, scientists, and technicians at Israel Aircraft Industries and at many other plants around the country, a source of pride for most Israelis. Two proto-types were already in flight test when the decision was taken. Who shot down the Lavi, the crowning achievement of Israeli technology? John Golan’s book “Lavi, the United States and Israel, and a controversial fighter jet” provides the answer in illuminating detail.
The Lavi followed IAI’s successful production of the Mirage aircraft (renamed the Nesher) after France embargoed aircraft shipments to Israel on the eve of the Six-Day War, and the production of the Kfir fighter, an improvement of the Mirage, that was engineered at IAI. It was designed to specifications determined by the Israeli Air Force that were based on the experience that had been gained by its pilots in the Yom Kippur War, and was meant to give Israel a degree of independence in the acquisition of fighter aircraft..
The program really took off after the support of the US government and the US Congress had been obtained. This support included the allocation of $250 million of annual US aid money for engineering development in Israel, plus $300 million for Lavi development in the US. Even more important was the permission that was granted for the use of American technologies in the aircraft and the participation of American companies in the project. The result was that the Lavi was in effect a joint Israeli-US project. With the explicit support of President Reagan and a large majority of the US Congress, the program seemed assured of success. The degree of US-Israel technological cooperation on defense system development reached at the time has not been equaled since.
But, as related by Golan, there was one man, US Secretary of Defense Caspar Weinberger, who was determined to kill the program. Golan describes how Weinberger mounted a “rogue offensive to kill a program that had been given the president’s stamp of approval”, by charging Dov Zackheim, a middle-level financial analyst at the Pentagon, with the mission of terminating the Lavi. From that point the plot thickens.
