Ukraine unveiled new test and repair station for US-made counter-mortar radars support

Yury Biryukov, an adviser to the Ukrainian defense minister, has unveiled photos of new mobile automatic test station or automatic test equipment (ATE) designed to support recently delivered US-made counter-battery radars.

The photos were published on the Yury’s Facebook page on 10 August on the occasion of the rehearsals of the military parade that will be held on Aug. 24 in Kyiv.

The new mobile ATE, mounted on the KrAZ chassis, is designed to provide diagnostic troubleshooting of various circuit card assemblies and other secondary repairable items of the counter-mortar radars that Ukraine has received from the USA.


The new mobile automatic test and repair station provides on-line fault detection and off-line fault diagnostics alert the operator to system faults, directing repair action to the unit that must be replaced. All repairs required can be performed by the crew of the new mobile ATE directly in the field.

According to Yury Biryukov, the new mobile automatic test station used for test and support of electronic of the US-made counter-mortar radars is developed with partners from other countries. Some of its components were received from the USA.

Earlier, the United States delivered AN/TPQ-36 and AN/TPQ-49 radar systems to Ukraine. The radar systems help to defend Ukrainian military personnel and civilians against rocket and artillery attacks.

The US-made compact and mobile counter-mortar radars can automatically locate medium-range enemy mortars, artillery, and rocket launchers. They can handle simultaneous fire from weapons at multiple locations, detecting and reporting their positions on the first round.

The automatic detection, tracking, and locating process is so fast that an enemy weapon’s position can often be pinpointed before its projectile impacts.

The system is so automatic and simple to operate that, once set up, the operator need not be present in the operation control shelter to determine a weapon’s location.

The United States has delivered Humvees, UAVs, counter-mortar radars, night vision devices, and medical supplies for Ukraine as part of military support.
