Northrop Grumman despleg\u00f3 con \u00e9xito sus primeros 21 sat\u00e9lites de comunicaciones para la Agencia de Desarrollo Espacial de EE. UU. Estos dispositivos que forman parte de la red en \u00f3rbita baja de la Arquitectura Espacial de Combate Proliferada (PWSA, constituyen el sistema vital para transmitir datos de empleo t\u00e1ctico y operacional, as\u00ed como alerta temprana de misiles, adem\u00e1s de extender la red de datos Link 16 hacia el espacio para mejorar la conectividad en general. Al distribuir las comunicaciones en m\u00faltiples plataformas, el sistema es m\u00e1s resiliente frente a interrupciones. Se estima el lanzamiento de un segundo grupo de 21 sat\u00e9lites y decenas de naves adicionales en los pr\u00f3ximos 6 meses. En total, los contratos de la empresa abarcan cerca de 150 sat\u00e9lites para comunicaciones y rastreo, cuyas entregas est\u00e1n programadas para 2028.<\/p>\n
Northrop Grumman has launched<\/a> and deployed its first 21 communications satellites for the US Space Development Agency\u2019s (SDA) Tranche 1 Transport Layer, part of a military network being built in low Earth orbit.<\/p>\n The satellites will relay tactical information between military forces and carry data from spacecraft that detect and track missiles.<\/p>\n Deploying the satellites is expected to expand communications capacity within SDA\u2019s Proliferated Warfighter Space Architecture (PWSA), which spreads these functions across a large constellation.<\/p>\n The Transport Layer provides the architecture\u2019s communications backbone, moving information between satellites and military users with minimal delay.<\/p>\n Separate missile-warning and tracking satellites collect sensor data that the network can then pass to forces on the ground, at sea, or in the air.<\/p>\n Northrop Grumman\u2019s satellites are designed to extend Link 16 into space.<\/p>\n The military data network allows participating forces to exchange tactical information, and satellite connections are intended to expand its reach.<\/p>\n Distributing communications across multiple spacecraft is also intended to make the network more resilient to disruption and reduce dependence on individual satellites.<\/p>\n A second group of 21 satellites will follow, and several dozen additional company-built PWSA spacecraft are scheduled to reach orbit over the next six months.<\/p>\n Satellite Programs<\/strong><\/p>\n Northrop Grumman\u2019s SDA orders cover around 150 satellites across Tranches 1, 2, and 3, including more than 30 spacecraft dedicated to missile warning and tracking.<\/p>\n Those sensor satellites will feed data into the Transport Layer for distribution to military forces.<\/p>\n The company is also pursuing a separate mission in geostationary orbit.<\/p>\n Last month, the US Defense Innovation Unit and Space Systems Command awarded Northrop Grumman and True Anomaly contracts to build prototypes that can observe other spacecraft.<\/p>\n
