The United States on Tuesday approved the sale of $20 billion in fighter jets and other military equipment to Israel as it prosecutes a 10-month-old war in the Gaza Strip although the Pentagon said deliveries would not begin for years.

U.S. Secretary of State Antony Blinken approved the sale of F-15 jets and equipment worth nearly $19 billion along with tank cartridges valued at $774 million, explosive mortar cartridges valued at over $60 million and army vehicles worth $583 million, the Pentagon said in a statement.

The Boeing Co. F-15 fighter jets were expected to take years to produce, and deliveries were expected to begin in 2029. Other equipment would begin delivery in 2026, according to the Pentagon.
