Defense Weather Satellite System

Last updated

The Defense Weather Satellite System (DWSS) [1] was a United States Department of Defense weather satellite system to have been built by Northrop Grumman Corporation [2] projected for launch in 2018. [3] In January 2012, the US Air Force cancelled the program. [4] It was replaced with the Weather System Follow-on Microwave (WSF-M). [5]

DWSS was a follow-on for the Defense Meteorological Satellite Program (DMSP) mission. The DWSS, together with the still continuing Joint Polar Satellite System (JPSS) project, was to replace the National Polar-orbiting Operational Environmental Satellite System (NPOESS) project which itself was cancelled in January 2010.

The Northrop Grumman B-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses. A subsonic flying wing with a crew of two, the plane was designed by Northrop and produced from 1987 to 2000. The bomber can drop conventional and thermonuclear weapons, such as up to eighty 500-pound class (230 kg) Mk 82 JDAM GPS-guided bombs, or sixteen 2,400-pound (1,100 kg) B83 nuclear bombs. The B-2 is the only acknowledged in-service aircraft that can carry large air-to-surface standoff weapons in a stealth configuration.

The National Polar-orbiting Operational Environmental Satellite System (NPOESS) was to be the United States' next-generation satellite system that would monitor the Earth's weather, atmosphere, oceans, land, and near-space environment. NPOESS satellites were to host proven technologies and operational versions of sensors that were under operational-prototyping by NASA, at that time. The estimated launch date for the first NPOESS satellite, "C1" or "Charlie 1" was around 2013. Issues with sensor developments were the primary cited reason for delays and cost-overruns.

The EADS/Northrop Grumman KC-45 was a proposed aerial refueling tanker aircraft based on the Airbus A330 MRTT. The United States Air Force (USAF) had ordered 179 KC-45As in the first stage of replacing the aging Boeing KC-135 Stratotanker tankers currently in service. However, the contest was reopened in July 2008, after Boeing's protest of the award was upheld. In response to the new contest, on 8 March 2010, Northrop Grumman announced it was abandoning its bid for the new contract, with its CEO stating that the revised bid requirement favoured Boeing. On 20 April 2010, EADS announced it was re-entering the competition and entered a bid with the KC-45. Eventually, the USAF selected the Boeing KC-46 Pegasus.

The Space Tracking and Surveillance System was a pair of satellites developed by the United States Missile Defense Agency (MDA) to research the space-based detection and tracking of ballistic missiles. Data from STSS satellites could allow interceptors to engage incoming missiles earlier in flight than would be possible with other missile detection systems. The STSS program began in 2001, when the "SBIRS Low" program was transferred to MDA from the United States Air Force. In December 2002, SBIRS Low Research & Development was renamed Space Tracking and Surveillance System (STSS).

<span class="mw-page-title-main">Joint Polar Satellite System</span> Constellation of American meteorology satellites

The Joint Polar Satellite System (JPSS) is the latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites. JPSS will provide the global environmental data used in numerical weather prediction models for forecasts, and scientific data used for climate monitoring. JPSS will aid in fulfilling the mission of the U.S. National Oceanic and Atmospheric Administration (NOAA), an agency of the Department of Commerce. Data and imagery obtained from the JPSS will increase timeliness and accuracy of public warnings and forecasts of climate and weather events, thus reducing the potential loss of human life and property and advancing the national economy. The JPSS is developed by the National Aeronautics and Space Administration (NASA) for the National Oceanic and Atmospheric Administration (NOAA), who is responsible for operation of JPSS. Three to five satellites are planned for the JPSS constellation of satellites. JPSS satellites will be flown, and the scientific data from JPSS will be processed, by the JPSS – Common Ground System (JPSS-CGS).

The Northrop Grumman RQ-180 is an American stealth unmanned aerial vehicle (UAV) surveillance aircraft intended for contested airspace. As of 2019, there had been no images or statements released, but growing evidence points to the existence of the RQ-180 and its use in regular front-line service. The use of the nickname "White Bat" in a 2021 video released by the US Air Force Profession of Arms Center of Excellence (PACE) suggests that the military may be preparing to release information on the RQ-180.

Northrop Grumman Innovation Systems (NGIS) was a sector of Northrop Grumman from 2018 through 2019. It was formed from Orbital ATK Inc. a company which resulted from the merger of Orbital Sciences Corporation and parts of Alliant Techsystems in 2015. Orbital ATK was purchased by Northrop Grumman in 2018. Northrop Grumman Innovation Systems designed, built, and delivered space, defense, and aviation-related systems to customers around the world both as a prime contractor and as a merchant supplier. It had a workforce of approximately 12,000 employees dedicated to aerospace and defense including about 4,000 engineers and scientists; 7,000 manufacturing and operations specialists; and 1,000 management and administration personnel. With Northrop Grumman's reorganization of its divisions effective January 1, 2020, NGIS was split, with most of the sector merging with other Northrop Grumman businesses into a new Space Systems sector.

The Weather System Follow-on Microwave (WSF-M) satellite is the United States Department of Defense's next-generation operational environmental satellite system. WSF-M will be a Sun-synchronous low Earth orbit (LEO) satellite with a passive microwave imaging radiometer instrument and hosted furnished Energetic Charged Particle (ECP) sensor. The Air Force Space Command intends to include ECP sensors on all future satellites for space weather monitoring, starting from the early 2020s.
