Following the Six Day War, the IDF pursued its earlier policy of strengthening the IAF and the Armored Corps. More than 50 percent of the defense budget was spent on converting the air force from French to American equipment. The Phantom and the Skyhawk (A-4M) planes became the backbone of the IAF. A French arms embargo against Israel, imposed in 1967 by President Charles de Gaulle to punish Israel for its aggression in the Six Day War, spurred the development of Israel’s local arms industry, and at the end of 1968, planning began to produce an Israeli fighter. At the same time, the Armored Corps was doubled in size, and the infantry was partially mechanized. Extensive use was made of captured enemy armor. The British refusal in 1969 to supply Chieftain tanks led to a government decision to develop a tank in Israel. The Navy began to employ missile boats armed with the Israeli-made Gabriel sea-to-sea missiles. Considerable effort was also invested in equipping and training troops for a possible future crossing of the Suez Canal.
In many other areas as well, a significant expansion occurred in the quality and quantity of weaponry. However, the extensive rearming of the IDF largely bypassed the infantry, greatly reducing its capacity to fight on the modern battlefield.
