SEATTLE (AP) _ Boeing Co. on Wednesday delivered its first two 767 airborne warning and control system radar planes to the Japanese government.

Boeing is under contract to build four 767 AWACS planes for Japan. Two more are to be delivered in early 1999.

There are currently 66 E-3 707 AWACS planes operating around the world. The 707 airframe ended in 1991, and the 767 platform was chosen to replace it.

Boeing currently has a $6.5 million contract with the Australian government to design an AWACS plane that would be smaller and less expensive than the 767 AWACS planes.
