The US Air Force has deemed the design of the Space Fence System developed by Lockheed Martin to be technically mature.


The Critical Design Review (CDR) for the next-generation space surveillance system conducted by the government representatives lasted for three days, following which it was indicated that the system will be able to meet all the specified requirements.


The Space Fence S-band radar system has been designed to detect, track, and catalog orbital objects in space over 1.5 million times daily in order to predict and prevent space-based collisions.


Lockheed Martin had to deliver around 21,000 pages of design documents prior to the CDR and undergo an eight-day design walkthrough in order to ensure that the system meets the performance requirements.


The CDR event was conducted with a small-scale demonstration system which was developed with end-item components.


Lockheed Martin Mission Systems and Training vice-president for Advanced Systems Steve Bruce said: "Completion of CDR marks the end of the design phase and the start of radar production and facility construction of the Space Fence system.

"Once complete, Space Fence will deliver revolutionary capability to the US Air Force with a flexible system capable of adapting to future missions requiring new tracking and coverage approaches."


"Once complete, Space Fence will deliver revolutionary capability to the US Air Force with a flexible system capable of adapting to future missions requiring new tracking and coverage approaches.


"We look forward to continuing our successful partnerships with the US Air Force Space and Missile Systems Center, Life-Cycle Management Center and Space Command."


The firm has used the latest monolithic microwave integrated circuit technology, including Gallium Nitride (GaN) semiconductor materials, for the Space Fence radar open architecture design.


GaN can deliver multiple advantages to active phased array radar systems, which includes higher power density, improved efficiency and better reliability than previous technologies.

KWAJALEIN ATOLL, Marshall Islands, March 23, 2015 – Lockheed Martin


Lockheed Martin Developed System to Improve Ability to Predict and Prevent Space Collisions


In a special February ceremony on Kwajalein Atoll in the Pacific Ocean – more than 2,100 nautical miles southwest of Honolulu – the U.S. Air Force and Lockheed Martin [NYSE: LMT] broke ground at the future six-acre site of the new Space Fence radar system.


The event marks the official start of construction for the S-band ground-based radar system, designed to replace the 1960s Air Force Space Surveillance System to improve the way objects are tracked in orbit and increase our ability to predict and prevent space-based collisions.


“The number of small satellites and satellite operators around the world is skyrocketing, rapidly crowding an environment already congested by the more than 17,000 pieces of space debris that we are able to track today,” said Steve Bruce, vice president for Advanced Systems at Lockheed Martin’s Mission Systems and Training business. “By comparison, when it comes online in 2018, Space Fence will enable the Air Force to locate and track hundreds of thousands of objects orbiting Earth with more precision than ever before to help reduce the potential for collisions with our critical space-based infrastructure.”


In addition to the radar arrays, the Kwajalein installation will include an on-site operations center and an annex to the current island power plant that will ensure the Space Fence system has everything necessary to provide continuous space situational awareness.


Lockheed Martin won the $915 million contract in June of 2014 to engineer, manufacture and deploy the Space Fence radar system. The total contract value is estimated at greater than $1.5 billion over an eight-year period of performance if all options are exercised.


The Lockheed Martin-led team – which includes AMEC Foster Wheeler and General Dynamics SATCOM Technologies – has decades of collective experience in space-related programs, including sensors, mission processing, cataloging, orbital mechanics, net-centric communications and facilities.


Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 112,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation’s net sales for 2014 were $45.6 billion.

1,5 milliard $ pour identifier les débris de l'espace



ARLINGTON, Virginie - La Défense américaine a attribué cette semaine à Lockheed Martin, première entreprise américaine de défense et de sécurité, un contrat de 914 millions $ US pour la conception d'un radar au sol qui identifiera et cataloguera avec une précision accrue plus de 200 000 débris en orbite autour de la Terre.

Dans le cadre du programme Space Fence («clôture de l'espace»), ce radar sera installé sur les îles Marshall, un archipel de l'océan Pacifique. La construction devrait débuter en 2015. Dans un communiqué, Lockheed Martin indique que la valeur totale du contrat est estimée à plus de 1,5 milliard $ sur une période d'exécution de huit ans.

Lockheed Martin «a 52 mois après l'attribution du contrat pour atteindre la capacité opérationnelle initiale», a précisé la Défense américaine. En 2018, autrement dit.
