Just heard on the news that it was an A-10
but only one pilot was killed, which makes sense because the plane is a single-seater. I only know of one 2-seat A-10 ever built and it was to test some night attack capabilities.
When you mentioned "both pilots" and "electronic warfare", my first guess was an EA-6B Prowler. It's the only tactical EW warplane in the arsenal right now, used by both the Navy and Air Force. It's a 4 seater derived from the old A-6 Intruder.
