Help please – Luftwaffe Eurofighter colision with Lear Biz Jet.

Hi All,
Can any body put me right please ? I have just been informed on another Forum of the above collision. Can any tell me do the Eurofighters have TCAS or other Air traffic avoidance warning systems, I seem to remember reading on this Forum that the UK’s fleet doesn’t but is this true ? and which other countries do or do not have them an the aircraft please ?
