The Netherlands to offer 4 Era VERA-NG radars for Ukraine air defense.
As reported by
, in view of bolstering Ukraine’s air defense, the Ministry of Defense of the Netherlands announces the purchase of four VERA-NG radars for an amount of 150 million euros. During the Ukrainian Defense Contact Group (UDCG), the Netherlands will announce it will allocate 40 million euros for the purchase of air defense equipment within the framework of a multilateral partnership.

Air defense and passive surveillance are major elements of modern military and security operations. Era's VERA-NG solves these topics by providing an advanced and modern passive surveillance system designed to detect, locate, identify and track air, land and sea targets.
The VERA-NG system consists of three radiation signal receivers (stations) with 360-degree azimuth coverage. In the center, there is a command post that receives and processes all information from the stations. The system's calculations transmit data on detected targets with range, azimuth, and altitude coordinates to air defense combat posts.
Passive Surveillance ESM Tracker (PET) VERA-NG is the most advanced Passive Surveillance System utilizing the multilateration Time Difference of Arrival (TDOA) principle. This unique system is designed for detection, localization, tracking and identification of the air, ground and naval targets as well as exceptional pulse and continuous wave signal analysis.
VERA-NG supports cross-border, long-term and long-range surveillance without alerting neighbouring nations. The system emits zero electromagnetic energy making it ‘invisible‘, i. e. it sees without being seen. It also provides strategic ELINT (Electronic Intelligence) information to collect, process and evaluate the ESM data for reference database. Here are some technical characteristics of the system: target detection range - 400 km with an accuracy of up to 20 m, operating frequency range - from 88 MHz to 18 GHz, number of simultaneous tracking targets - up to 200, information update time - from 1 to 5 seconds. The radar can work in any weather conditions.
