The U.S. State Department approved sale of defense aircraft to Qatar, Kuwait worth up to $31.2 billion combined, Reuters reported.

Qatar asked to purchase 72 of the fighter aircraft F-15QA for $21.1 billion.

Kuwait wants 32 Boeing F/A-18 jets at a cost of $10.1 billion, including weapons and support systems, the Pentagon said. Kuwait signed a deal earlier this year with Leonardo SpA to buy 28 Typhoons.

As State Department believed, transactions will strengthen U.S. national security and strengthen the defenses of Qatar and Kuwait, which are friendly countries. At the same time the sale of fighter aircrafts will not change military balance in the region.
