CATOBAR (Catapult Assisted Take Off But Arrested Recovery) is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier. Aircraft launch using a catapult assisted take-off. However, these are conventional, rather than STOVL aircraft, and thus require arrestor wires to land on the ship. Only three countries operate carriers that use the CATOBAR system; the U.S. Nimitz class, USS Enterprise (CVN-65) and USS Kitty Hawk (CV-63), France's Charles De Gaulle, and Brazil's NAeL São Paulo. Four aircraft carriers, (front-to-back) Principe de Asturias, amphibious assault carrier USS Wasp, supercarrier USS Forrestal and light V/STOL carrier HMS Invincible, showing size differences. ... u suk usuk u suk u suk u suk u suk u suk u suk u suk u suk usuk suk suk suk suk suk suk suk suk suk suk suk suk suk suk suk suk{| class=wikitable |- ! header 1 ! header 2 ! header 3 |- | row 1, cell 1 | row 1...
