I recently became aware of the danish group called “Terma”. I visited their website: https://www.terma.com/. They were a huge part of the sensors on the f-35 including, the Common Bus Interface (CBI) (A part that connects all the info from the radar into 1 single program.), Core Interface Module ( Gathers all the info from the radar, AN/APG-81, into 1 readable screen.), Analog IF Receiver Module ( Gathers all the micro waves from the radar and makes it into info. ), Drain Power Supply Module ( Delivers power to all the IF components from the radar. )
Note that there are many more components that arent realeased to the public that they made. And note that the info about the listed components are not fully correct.
