The U.S. Army has awarded a substantial $2.1 billion contract to RTX for the initial production of its advanced Lower Tier Air and Missile Defense Sensor (LTAMDS) systems. The deal is part of Washington’s foreign military sales to Poland, reflecting the ongoing defense cooperation between the two nations.

The Pentagon announced that the work under this contract will be carried out in Massachusetts and is expected to be completed by 2028. However, the exact number of LTAMDS units delivered to Poland remains undisclosed.

The LTAMDS is a next-generation radar system designed to provide comprehensive 360-degree coverage of the threat environment. It is powered by Raytheon’s Gallium Nitride technology, which enables it to detect a wide array of threats including manned and unmanned aircraft, cruise missiles, ballistic missiles, and hypersonic missiles.

he radar system features three antenna arrays to ensure complete situational awareness, with the capability to ensure that “nothing goes unseen” by military operators.

Lower Tier Air and Missile Defense Sensor (LTAMDS) is the first in a family of radars Raytheon is calling GhostEye. This radar is designed to defeat advanced and next-generation threats, including hypersonic weapons, or those that fly faster than a mile a second.

• Lower Lifecycle Costs: Designed for cost-effective maintenance and long-term operational sustainability.
• Deployable: Can be quickly transported and deployed to different locations as required by the tactical situation.

In recent tests, the LTAMDS demonstrated its advanced capabilities by successfully detecting and engaging a complex target – a cruise missile surrogate flying at high altitude and speed – during a live-fire exercise. In another trial, the radar system was crucial in assisting an SM-6 missile to intercept a target with high precision.

In addition to the recent contract, Poland bolstered its defense capabilities in September 2023 by purchasing 12 LTAMDS radars to complement its existing Patriot surface-to-air missile launchers. This acquisition is part of Poland’s strategic effort to enhance its national defense infrastructure in response to evolving security challenges.

The LTAMDS systems will significantly enhance Poland’s defense capabilities, offering advanced detection and interception solutions to address a wide range of aerial threats. The collaboration underscores the strengthening of military ties between the U.S. and Poland and the commitment to improving defense systems through cutting-edge technology.
