Collaborating with Indra, Hensoldt is leading the project for an upgraded AESA radar for the Eurofighter Typhoon, incorporating components from the baseline CAPTOR-E Mk0. The projected started in 2020 after the German and Spanish government approved funds totalling €1.5 billions, covering development, integration and delivery to retrofit the entire fleet of Tranche 2/3 Luftwaffe Eurofighters and an initial 5 Spanish Air Force aircraft.

The following Luftwaffe Quadriga (38 aircraft) and Spanish Halcon I (20 aircraft) Eurofighters were later also contracted with Mk1 radars. The planned Halcon II procurement will likely result in an order of an additional 25 airframes, raising the number of orders to approximately 200 radar sets.
Besides Hensoldt and Indra the original consortium partner Leonardo is also involved in the project, mainly dealing with supplying legacy components from the Mk0 radar such as the radar processor and modified components of the antenna power supply & control unit.
One of the main hardware changes compared to existing Mk0 radars are new Gallium-Nitride (GaN) based wideband T/R modules. The introduction of new T/R modules was necessitated by the Luftwaffe’s requirements for longer detection ranges and UHR SAR imagery with 10cm resolution.
The other major hardware development is the introduction of a digital multi-channel receiver. Compared to the old (partly analog) 3 channel receiver with PowerPC processors, the new receiver is fully digital and makes use of modern multi-core processors. The new hardware greatly improves the radar’s electronic countermeasure (ECM). Additionally the added data capacity also opens up possibilities for the introduction of Electronic Attack (EA) and other non-traditional radar features.
In 2022 problems arose for the project as the German authorities failed to certify the new multi-core processors with existing certification processes, which resulted in delays and cost-overrun. In the same year the decision was made to adapt the Eurofighter for the Electronic Combat and Reconaissance (ECR) mission role, which led to additional Electronic Warfare features being required for the Mk1 radars. This resulted in a follow-up contract worth €200 million in late 2023, covering the additional expenses.
The program is structured to have a 2-phase maturation stage, with the radars initially being delivered in a ‘Step 1’ configuration, featuring the new T/R modules and the digital receiver. The software will also be brought to a new standard compared to existing Mk0 updates. The ‘Step 2’ improvement is planned to be fielded by 2028. The objective is to revamp the software and task architecture while also modernize the radar processor, doubling the amount of radar features. The upgrade will introduce new offensive Electronic Warfare capabilities and improve the performance of existing modes. After the upgrade developers and engineers will also have the possibility of remotely updating the radar’s software.
Current plans foresee the first Mk1 radar sets to be fielded with the delivery of the first Luftwaffe Tranche 4 (Quadriga) aircraft in 2025.

Yes. Mk.1 is meant to perform that as well, but it will only receive that capability in Phase 2.
