As was later reported in Aviation Week and Space Technology, CIA and the Defense Department, in partnership with the FBI, set up a program to do just what we had discussed: modified products were devised and "made available" to Line X collection channels. The CIA project leader and his associates studied the Farewell material, examined export license applications and other intelligence, and contrived to introduce altered products into KGB collection. American industry helped in the preparation of items to be "marketed" to Line X. Contrived computer chips found their way into Soviet military equipment, flawed turbines were installed on a gas pipeline, and defective plans disrupted the output of chemical plants and a tractor factory. The Pentagon introduced misleading information pertinent to stealth aircraft, space defense, and tactical aircraft.(4) The Soviet Space Shuttle was a rejected NASA design.(5) When Casey told President Reagan of the undertaking, the latter was enthusiastic. In time, the project proved to be a model of interagency cooperation, with the FBI handling domestic requirements and CIA responsible for overseas operations. The program had great success, and it was never detected.
In a further use of the Farewell product, Casey sent the Deputy Director of Central Intelligence to Europe to tell NATO governments and intelligence services of the Line X threat. These meetings led to the expulsion or compromise of about 200 Soviet intelligence officers and their sources, causing the collapse of Line X operations in Europe. Although some military intelligence officers avoided compromise, the heart of Soviet technology collection crumbled and would not recover. This mortal blow came just at the beginning of Reagan's defense buildup, his Strategic Defense Initiative (SDI), and the introduction of stealth aircraft into US forces.
