Rank 81 documents the Saab AJ 37 Viggen — the canard-delta strike fighter that entered Flygvapnet service in 1971 as Sweden's primary maritime and land-attack platform against Soviet Baltic fleet concentrations. Powered by a Volvo RM8 turbofan derived from the Pratt & Whitney JT8D and armed with RB 04E anti-ship missiles and cannon, the Viggen's reverse-thrust landing capability and road-base operations doctrine made it uniquely suited to Swedish territorial defence. JA 37 fighter and SK 37 trainer variants extended the family through the Cold War; the splinter camouflage and NORDIC DEFENDER brush slogan on this plate reference the type's Baltic strike identity. Split-view blueprint art renders the splinter-camo exterior and RM8 wireframe exactly as the master PNG dictates.
