哈里斯（L3Harris）开始在“宽视野”导弹防御卫星上进行预发射工作
华盛顿—
美国太空部队的导弹预警卫星，
六年的工程，已接近完成。
开发传感器的公司
L3Harris于4月6日获得930万美元的合同，用于维护和准备在2021年发射的卫星。
该合同是用于广视场导弹探测卫星的发射前和发射后服务。
L3Harris
developed a staring sensor that was mounted on a satellite bus supplied by Millennium Space Systems, a subsidiary of Boeing.
The U.S. Space Force’s Space and Missile Systems Center
plans to send the satellite to geosynchronous Earth orbit no earlier than August 2021.
The Wide Field of View, or WFOV, satellite
will be part of a rideshare mission known as USSF-12, currently scheduled for no earlier than August 2021 on a United Launch Alliance rocket.
WFOV is a “testbed” satellite
that is not part of a missile-warning constellation but a stand-alone experiment.
At 1,000 kilograms,
it’s about one-fourth the size of the Space Based Infrared System (SBIRS) spacecraft
that currently perform strategic and tactical missile warning for the Defense Department.
