米宇宙軍：広域ミサイル防衛衛星
開発に6年、ほぼ完成に漕ぎ付けました。
センサー開発会社：L3Harris
L3Harrisは、2021年打ち上げに向け、衛星準備業務で、4月6日､930万ドルの契約を受注。
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.
