On October 17, the U.S. Army awarded a contract for its new Lower Tier Air and Missile Defense Sensor (LTAMDS), a competition to develop a new radar for the Patriot and future air and missile defense systems. The winning radar, designed by Raytheon, has a longer detection range than the legacy AN/MPQ-53 system. It also features 360-degree coverage, even though the Army had retracted its requirement for 360-degree coverage in 2018. Initiated in 2017, the LTAMDS program is expected to field six prototype radars by Fiscal Year 2022.
