Dwa wojskowe satelity 01.07. o 23:15:00.196 z Cape Canaveral wystrzelona została RN Atlas-5/541. Wyniosła ona w T+4h 46' 20" na orbitę o parametrach: hp=36106 km, ha=36168 km, i=0,0° w ramach misji USSF-12 satelitę wczesnego uprzedzania WFOV (Wide Field of View Testbed missile-warning satellite) oraz USSF-12 Ring (NG ESPA Star bus), prawdopodobnie prototyp satelity inspekcyjnego.

United Launch Alliance’s Atlas 5 rocket lifts off from Cape Canaveral Space Force Station, Florida, to begin the USSF-12 mission for the U.S. Space Force. Credit: United Launch AllianceA United Launch Alliance Atlas 5 rocket fired off its launch pad at Cape Canaveral Friday on a six-hour climb to geosynchronous orbit, deploying a classified payload and a U.S. Space Force satellite to test an improved infrared heat-sensitive sensor design that could help detect and track enemy hypersonic missiles. (...)
The mission, designated USSF-12, released the two Space Force satellites into an on-target orbit more than 22,400 miles (about 36,100 kilometers) over the equator, according to ULA. The spacecraft are expected to maneuver into their final operating positions a couple hundred miles lower in the geostationary belt, where they will orbit in lock-step with Earth’s rotation.
One of the payloads, called the Wide Field of View Testbed, will demonstrate a new instrument design that could help give the military better warning of a missile attack. The USSF-12 Ring spacecraft, riding below the WFOV Testbed payload during the launch sequence, hosts classified experiments and tech demo payloads. (...)
Four strap-on solid rocket boosters and a liquid-fueled RD-180 engine combined to produce about 2.3 million pounds of thrust at liftoff. Credit: United Launch AllianceThe Space Force’s Wide Field of View, or WFOV, Testbed surveillance satellite was one of the payloads on the USSF-12 mission. The WFOV Testbed satellite is demonstrator for a next-generation space-based sensor designed to detect rocket launches and provide early warning of a missile attack.
Built in El Segundo, California, by Millennium Space Systems, a subsidiary of Boeing, the WFOV Testbed satellite carries an optical staring instrument to detect the exhaust plumes from missile launches, demonstrating the wide-area sensor for future use in the military’s operational early warning systems.
The WFOV mission will demonstrate the optical sensor technology for use on future missile warning missions in the Space Force’s Overhead Persistent Infrared, or OPIR, program. The next-generation OPIR missions will replace the Space Based Infrared System, or SBIRS, missile warning satellites that currently provide missile detection and early warning coverage.
The Space Force is partnering with the Space Development Agency and the Missile Defense Agency on a next-generation fleet of missile warning satellites in low Earth orbit and geosynchronous orbit. (...)
The infrared sensor on the WFOV Testbed satellite was developed by L3Harris. The Space Force said the infrared instrument has “first in its class sensor sensitivity” across its wide field of view, capable of tracking dim targets over large areas. The new sensor technology is necessary as threats shift from primarily large ballistic missiles to smaller projectiles, such as hypersonic cruise missiles. (...)

After a day-long delay due to poor weather, the USSF-12 mission successfully launched at 7:15 p.m. EDT Friday. Photo Credit: ULA(...) Formal preparation for the USSF-12 mission got underway on 27 May, with the Launch Vehicle On Stand (LVOS) campaign to erect the Atlas V’s 107-foot-long (32.6-meter) Common Core Booster (CCB) inside the 30-story Vertical Integration Facility (VIF) at SLC-41. The CCB is powered by a Russian-heritage RD-180 dual-nozzle engine, fueled by liquid oxygen and a highly refined form a rocket-grade kerosene, known as “RP-1”. The engine assigned to this mission marked the 100th RD-180 to fly. (...)
