WASHINGTON (Dispatches) -- The United States on Thursday approved a series of deals worth more than $7 billion to supply military helicopters, planes and missiles to four of its Arab allies.
The biggest agreement announced on Thursday was for a $3.51 billion sale to the Saudi kingdom of 48 CH-47F Chinook cargo helicopters with spare engines and machine guns.
The United Arab Emirates wants to spend $3.5 billion on 27 AH-64E Apache attack helicopters plus support equipment, made by Boeing and Lockheed Martin.
Qatar, meanwhile, has requested eight C-17 military cargo jets and spare engines in a pair of contracts totaling $781m.
And Washington has also approved a contract to sell Morocco 1,200 TOW 2A anti-tank missiles made by U.S. arms giant Raytheon for $108 million.
The green light, announced by the State Department, will mark another windfall for plane maker Boeing and other U.S. arms manufacturers.   
But critics may deride the sales because of Saudi Arabia’s and the UAE’s ongoing war on Yemen.
Boeing and Honeywell Aerospace will be the main contractors. As many as 60 Americans - both private and government employees - will work in Saudi Arabia to maintain the aircraft.
Although the State Department has approved the sales after consultation with the Pentagon, Congress could still block them in theory.
Since all four Arab countries involved are U.S. allies and past major arms purchasers, however, the contracts are expected to be approved, despite human rights groups' criticism of U.S. support for the Saudi military campaign against Yemen, which has killed many civilians.
In Yemen, the Houthis have accused the U.S. of arming and supporting the Saudis, who intervened on the side of Yemen's exiled government.
The war has killed more than 10,000 people and displaced more than three million.
Persian Gulf countries have gone on massive military spending sprees recently.
In late November, Kuwait bought 28 F-18 Super Hornets to replace a fleet of earlier versions of the U.S. fighter jets. And the U.S. Senate cleared a $1 billion-plus sale of Abrams tanks to Saudi Arabia in September.
