Hensoldt to equip German F214 Sachsen-class frigates with new radars


According to a press release published by Hensoldt on August 24, 2021, the sensor solutions provider, together with Israel Aerospace Industries (IAI), is supplying new radars to the German Navy to modernise the sensor technology of the F124 air defence frigates. The Federal Office of Bundeswehr Equipment, Information Technology and Operation (BAAINBw) has placed an order worth approximately 200 million euros for the delivery and installation of four sensor systems consisting of radar and IFF system respectively.

With this order, the F124 frigate's radars will be refurbished to overcome the obsolescence of electronics components. The order also marks the start of the development of national capabilities in the field of Ballistic Missile Defence (BMD). It includes a shore facility that is a fully functional copy of the ship's radars. It not only enables training for users and service technicians but also allows further developments to be tested on land prior to onboard installation.

To this end, HENSOLDT has entered into strategic cooperation in the field of BMD-capable wide-range radars in S-band with IAI subsidiary ELTA Systems Ltd. This supplies the German customer with a combination of a national partner for certification and long-term support, as well as market-available systems that have been tried and tested in the field.

Previously, the contract for the modernisation of land-based air surveillance in the HADR NF programme, also based on cooperation with IAI’s ELTA, was awarded to HENSOLDT. The radars used in both projects are largely identical in construction and thus also offer the customer advantages in terms of logistical supply and thus the long-term operation of the systems. In this way, further developments can also be used cross-sectionally and thus be introduced more cost-effectively.

The F124 Sachsen class is Germany's latest class of highly advanced air-defence frigates. The design of the Sachsen-class frigate is based on that of the F123 Brandenburg class but with enhanced stealth features designed to deceive an opponent's radar and acoustic sensors.

The ships of the Sachsen class are 132.15 meters (433.6 ft) long at the waterline and 143 m (469 ft) long overall. They have a beam of 17.44 m (57.2 ft) and a draft of 5 m (16 ft), though the draft increases to 7 m (23 ft) at the sonar array in the bulbous bow. They displace 5,690 long tons (5,780 t) at full load. Steering is controlled by a single roll-stabilized rudder; the ships have a turning radius of 570 m (1,870 ft). The frigates have a crew of 38 officers, 64 petty officers, and 140 enlisted sailors.
