Ground Based Interceptor (GBI)
« on: January 29, 2013, 12:13:59 pm »
CTV-01 test just occurred on 27 January 2013.

No target involved.

The EKV separated from the booster, and carried out a series of preprogrammed manouvers to validate that the problem which caused the last test in December 2010 to fail had been correctly identified and fixed.

The test was apparently a success; which validates the CE-II (Capability II) EKV that has been sidelined from being deployed for the last two years due to the FTG-06a failure.

Raytheon kill vehicle succeeds in developmental flight test
Mission validates thruster redesign for enhanced ballistic missile defense
VANDENBERG AIR FORCE BASE, Calif., Jan. 28, 2016 /PRNewswire/ -- A Raytheon Company (NYSE: RTN) Exoatmospheric Kill Vehicle (EKV) successfully completed a data-gathering mission during a Missile Defense Agency flight test. The mission's objective was to observe in-flight performance of redesigned components and gain valuable information on evolving threat classes.

EKVs are designed to destroy incoming ballistic threats while they are still in space. As part of the MDA test of the Ground-based Midcourse Defense system, a ballistic missile target was launched and purposely not intercepted to demonstrate for maximum maneuvering and data collection.

The successful mission proved the effectiveness of a recent redesign of the EKV thrusters, which provides the control necessary for lethal impact with incoming threats while safely outside of the Earth's atmosphere. The testing was supported by Raytheon's sea-based X-band radar (SBX) and AN/TPY-2 radar – both play critical roles in supporting the Ground-based Midcourse Defense system. 

"This was a remarkable data-collection opportunity," said Dr. Taylor W. Lawrence, president of Raytheon Missile Systems. "These are among our industry's most complex systems. Testing is critically important to ensuring the advancement of reliable kill vehicles for the protection of the U.S. homeland."

The Missile Defense Advocacy website should find a better writer, their articles are borderline incoherent.

MDA seeks industry ideas for new GBI booster upgrade

The Missile Defense Agency is seeking ideas from industry on new booster designs for the Ground-based Interceptor, and is signaling plans for the government to be the lead systems integrator  -- supplanting an industry prime contractor -- in a project to upgrade the entire Ground-based Midcourse Defense guided missile fleet with nearly 80 booster stacks beginning in 2023.

Unfortunately, this could be considered to be yet another case of too little, too late.

Better late than never.  Still, I think we both know this is nothing but talk.  One hears of all this new plans for speeding up carrier acquisition, restarting the F-22 line, etc. etc. etc. and all the while they cut the defense budget.  Putin and Xi must wake each day wondering what new gift the idiotic West will lay at their feet.
"DARPA Hard"  It ain't what it use to be.

MDA approves preliminary design, 'dual-pol' tech for Long Range Discrimination Radar

Quote
The Missile Defense Agency has approved Lockheed Martin's preliminary design for the Long Range Discrimination Radar -- a program central to Pentagon plans to improve homeland defense by bolstering the Ground-based Midcourse Defense program with an unprecedented ability to detect ballistic missile threats by the end of this decade.

The LRDR is a nearly $1 billion project to emplace a new radar in Alaska by 2020 as part of the agency's plans to upgrade the GMD program to what it calls the Robust Homeland Defense configuration by providing an improved persistent view of long-range ballistic missiles -- particularly those launched from North Korea -- during the midcourse of flight.

Following a March 21-22 review chaired by two senior MDA officials -- Keith Englander, director for engineering, and Rich Ritter, director for command, control, communications, computers, intelligence, surveillance and reconnaissance -- the government approved the development project to proceed with further design efforts, according to Chandra Marshall, Lockheed Martin program director for LRDR.

The two-day assessment, at Lockheed's Moorestown, NJ, facility, included assessments of a prototype LRDR system.

"Lockheed Martin utilized a scaled LRDR system to successfully demonstrate Critical Technology Elements in a relevant end-to-end environment," according to an April 20 company statement.

Marshall, in an April 20 interview with reporters, declined to identify specific technologies assessed during the review, citing classification sensitivities.

"But I can tell you that one of the key areas, one of the technology upgrades we made . . . is introducing dual-pol technology," Marshall said, using the shorthand for "dual-polarized." This technology -- used today by weather-forecasting radar -- "improves the ability to maximize discrimination," she said.

By incorporating dual-pol technology, the LRDR promises to provide a two-dimensional view of a ballistic missile's track. The two-face radar will send both horizontally and vertically polarized electromagnetic waves; when these bounce off a threatening ballistic missile and are received back, each wave is separately processed and then synthesized to produce a two-dimensional view.

During the review, Lockheed persuaded MDA officials that key technologies for the new radar are Technology Readiness Level 6, meaning a system or subsystem prototype was demonstrated in a relevant environment, according to Marshall. The program also demonstrated Manufacturing Level Readiness 6, which indicates ability to proceed into engineering and manufacturing development.

Next month, MDA will review Lockheed's design proposal for the equipment shelter that will house the new radar, due to eventually be installed at Clear Air Force Station, AK. In September, MDA plans a critical design review of the new radar followed by a final design review in November; a production decision is expected in the spring of 2018, according to Marshall.

Lockheed is due to deliver the radar to MDA in 2020, she said.

The high-powered S-band radar incorporates gallium-nitride components and is similar to the Space Fence radar system Lockheed is building for the Air Force “but is additionally capable of discriminating threats at extreme distances using the inherent sideband capability of the hardware coupled with advanced software algorithms,” according to the company statement.

"The key part of this radar is the ability to do precise, long-distance detection and characterization of ballistic missiles," said Marshall. "This radar can do that better than any radar fielded today."

Gen. John Hyten, head of U.S. Strategic Command, told the Senate Armed Services Committee on April 4 that the LRDR is a top priority.

Along with the LRDR, MDA plans other enhancements as part of the Robust Homeland Defense modernization phase of the GMD program, including the Upgraded Early Warning Radar, a redesigned kill vehicle, a new ground-based interceptor booster design -- the C3 -- to outfit the fleet with new 50-inch-diameter boost vehicles to lift the exoatmospheric kill vehicle in a position to intercept an incoming ballistic missile warhead, and other ground system improvements.

In October 2015, MDA awarded Lockheed a contract potentially worth $784 million to develop, deploy, test, and operate the LRDR. MDA's fiscal year 2017 budget request outlines plans to spend $896 million on the new radar between 2015 and 2021.

I would guess that some of the impetus for an upgraded booster is to accommodate the MIRV'd interceptors from the MOKV program.
