Rafale B Two-seater version for the French Air Force. Rafale C Single-seat version for the French Air Force. Rafale M Carrier-borne version for the French Naval Aviation, which entered service in 2001. For carrier operations, the M model has a strengthened airframe, longer nose gear leg to provide a more nose-up attitude, larger tailhook between the engines, and a built-in boarding ladder. Consequently, the Rafale M weighs about 500 kg (1,100 lb) more than the Rafale C
