WINDFINDING A/C

A specialized lead aircraft tasked with gathering real-time wind speed and direction data at altitude to ensure the following formation achieved maximum bombing accuracy over the target. Operational Context Target File 271-3_117 documents a nine-aircraft formation strike on March 18, 1945, directed against the Porto Nogaro Cellulose Factory (coordinates H395914). Porto Nogaro served as a vital inland port in the Friuli-Venezia Giulia region. The targeting of a cellulose facility was of high strategic priority for the Mediterranean Allied Air Forces (MAAF); cellulose was a core precursor for the production of nitrocellulose, an essential component for smokeless powder and various explosives required by the German Wehrmacht. The methodology of this raid—utilizing a specialized "Windfinding A/C" (Baltimore 513 Hv, piloted by Lt. Muir)—illustrates the technical refinement of the SAAF's tactical doctrine by early 1945. This approach contrasts with the squadron’s earlier, more direct tactical pressure during the 1943 battles for the Bernhardt and Gustav Lines. In November 1943, for instance, 21 Squadron targeted tactical bottlenecks such as location H055630 to fracture immediate German front-line logistics. By March 1945, as part of Operation Bingo, the focus had shifted to the total industrial and logistical paralysis of German Heeresgruppe C in the Po Valley and the Alpine approaches. The mission was led by senior squadron leadership, with Major Dieu in aircraft 575 P. The recorded mission time of 2 hours and 45 minutes for all aircraft signifies a concentrated, efficient strike against the factory, designed to deny the enemy domestic ordnance components and accelerate the collapse of Axis resistance in the Northern Adriatic sector. 118 Phase 1: Verification & Extraction Identity Check: 19th MARCH, 1945
