News again :
The fifth batch will have :
- GaN modules instead of AsGa for Spectra, for better jamming capabilities, and improved band coverage ;
- possibly GaN modules for the radar too ;
- maybe conformal arrays ;
- additionnal jamming capabilities in the radar (up to now, this task is handled by Spectra alone).
In addition, we learn that Spectra already costs at least €3Bn in developpement.
This would confirm the claim according to which Spectra cost between a quarter and a third of the whole aircraft.
At last, DDM NG (for the fourth batch) is DIRCM-ready, and has a (passive) all around surveillance capability.
