Eurofighter Typhoon

The Typhoon is a twin-engined, canard-delta wing, multirole combat aircraft. It is a highly agile aircraft at both supersonic and low speeds, achieved though having an intentionally relaxed stability design. It has a quadruplex digital fly-by-wire control system providing artificial stability, as manual operation alone could not compensate for the inherent instability. The fly-by-wire system is described as "carefree", and prevents the pilot from exceeding the permitted manoeuvre envelope.
In 2004, United States Air Force Chief of Staff General John P. Jumper said after flying the Eurofighter, "I have flown all the air force jets. None was as good as the Eurofighter."

So it's an American jet, I thought by the name it was from Europe.

Like most modern jets I really like its looks.

Has it ever been used in combat?

Actually, the Eurofighter Typhoon is a European jet. It is used by the RAF, the Luftwaffe, the Italian Air Force, and the Spanish Air Force.
Recent service:
On 18 March 2011, British Prime Minister David Cameron announced that the UK would deploy Typhoons, alongside Panavia Tornados, to enforce a no-fly zone in Libya. On 21 March RAF Typhoons flew their first ever combat mission while patrolling the no-fly Zone.
On 12 April 2011 a mixed pair of RAF Typhoon and Tornado GR4 dropped precision-guided bombs on ground vehicles operated by Gaddafi forces that were parked in an abandoned tank park. Chief of the Air Staff, Air Chief Marshal Sir Stephen Dalton, revealed during the Royal Aeronautical Society's Aerospace 2011 conference in London, that each aircraft dropped one GBU-16 Paveway II 454 kg (1,000 lb) laser guided bomb which struck "very successfully and very accurately". The event represented "a significant milestone in the delivery of multi-role Typhoon."

The Eurofighter consortium claims their fighter has a larger sustained subsonic turn rate, sustained supersonic turn rate, and faster acceleration at Mach 0.9 at 20,000 feet than the Grumman F-14 Tomcat, F-15 Eagle, F-16 Fighting Falcon, McDonnell Douglas F/A-18 Hornet, Dassault Mirage 2000, Dassault Rafale, the Sukhoi Su-27, and the Mikoyan MiG-29.
