The Pentagon puts to orbit the satellite for $1.5 billion for the organization of military communication

On March 26, 2020 successful start of the carrier rocket Atlas V with the AEHF-6 satellite developed by Lockheed Martin company for needs of the Ministry of Defence of the USA took place. The Pentagon invested about $1.4 billion in this project.

The rocket flew up at 4:18 p.m. on time of east coast of the USA (11:18 p.m. Moscow time) from Cape Canaveral launch site (State of Florida). Initially start was planned at 2:57 p.m. (9:57 p.m. Moscow time), however was automatically postponed several seconds prior to start because of failure in work of computer systems.

The carrier rocket Atlas V started into an orbit with the next AEHF satellite (Advanced Extremely High Frequency

The AEHF-6 satellite is the highly protected means of communication for transfer of the major defense information for key users of the country. It will provide the top management of the reliable communication line with armed forces in any conflict, including in nuclear wars, - the American operating company of United Launch Alliance (ULA) said.

The AEHF satellites should provide with the communication protected according to the military standard troops of the USA, Britain, Canada and the Netherlands. A system will be considered as complete when in space at the same time there are six such devices: then signals will cover a planet belt between the 65th parallels of northern and southern latitude. 

The first five satellites were put to orbit using the Atlas V rockets in 2010, 2012, 2013, 2018 and 2019. They provide communication of representatives of the American command, protected and steady against noises, with the unrolled military units and divisions.

The AEHF satellites use a large number of the narrowly targeted beams directed to Earth for transmission of messages to users and from them. Crosstalk couplings between satellites allow them to route messages live, but not through a ground station. Satellites are intended for ensuring interference immune communication with the low probability of interception. They include a radio technology  frequency-hopping and also antennas with  the phased grid  which can adapt the  direction characteristics  to block potential interfering sources.^[1]
