This archival edition presents the original Operating Instructions Manual for the J2M3 Model 21, the primary production variant, drawn from wartime design histories and post-war technical evaluations.\u003c\/p\u003e\u003chr\u003e\u003ch3\u003eAerodynamic Design \u0026amp; Airframe Engineering\u003c\/h3\u003e\u003cp\u003eChief Designer \u003cstrong\u003eJiro Horikoshi\u003c\/strong\u003e engineered the Raiden around a single priority: intercept and destroy high-altitude bombers before they reached their targets.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaminar-Flow Airfoil:\u003c\/strong\u003e The J2M incorporated an advanced symmetrical wing profile inspired by the LB24 airfoil.
