US tested a radar suspiciously similar to the Russian S-400’s radar

WASHINGTON, (BM) – Raytheon Company completed the first round of testing of the first partially populated radar antenna array for the U.S. Army’s Lower Tier Air and Missile Defense Sensor, or LTAMDS, learned according company statement.

The milestone comes less than five months after the U.S. Army selected Raytheon to build LTAMDS, a next-generation radar that will defeat advanced threats like hypersonic weapons.

“Concluding these initial tests brings Raytheon one step closer to putting LTAMDS into the hands of service members,” said Tom Laliberty, vice president of Integrated Air and Missile Defense at Raytheon’s Integrated Defense Systems business. “Raytheon and our supplier partners continue to make the right investments in people, technology and manufacturing capability to ensure we meet the U.S. Army’s Urgent Materiel Release.”

The testing consisted of calibrating LTAMDS primary antenna array in an indoor, climate controlled test range, and evaluating its performance against simulated targets. With testing complete, the array is being mounted on a precision-machined enclosure for integration and further evaluation. It will then commence testing at an outdoor range against real-world targets.

LTAMDS consists of a primary antenna array on the front of the radar, and two secondary arrays on the rear. The radar antennas work together to enable operators to simultaneously detect and engage multiple threats from any direction, ensuring there are no blind spots on the battlefield.

LTAMDS’ primary array is roughly the same size as the Patriot radar array, but provides more than twice Patriot’s performance. While it is designed for the U.S. Army’s Integrated Air and Missile Defense system, LTAMDS will also be able to preserve previous Patriot investments.

Some military experts said that Raytheon’s radar is very similar to Russian S-400’s radar. Considering the fact that the United States has neither missiles capable of approaching hypersonic targets in its speed, nor simulating targets, all this raises many questions, however, the radar itself was much more interesting for specialists – its design and operating principle are very similar on the S-400 radar.

“In the US, they tested a radar station to detect hypersonic targets. It will be installed on the Patriot anti-aircraft missile system. In the course of laboratory tests, the specialists tuned the transceiver modules and tested their work by simulating various targets. Now the creators need to collect all the elements of the station in one building, and then begin field trials, including with real goals. Due to the fact that the radar uses new material, specialists were able to organize the redundancy of the transmit-receive modules. This made it possible to increase the resolution of the station and the detection range, as well as to increase its reliability,” military expert told Ferra news agency.

A similar design radar is part of the Russian S-400 and S-300 air defense systems, which does not exclude the possibility that the United States only copied the Russian development, announcing that Washington has protection against hypersonic weapons.

However, given the fact that tests with real goals have not been carried out, the effectiveness of a multi-billion dollar project is in very great doubt.
