The SSR XF-47.
Based on the Repblic XP-47, the SSR developed the XF-47 to counter threats from Hydra's Luftwaffe inventory, the Soviets and even craft from "beyond Earth"
Howard Stark high modified the basic Republic air frame for enhanced performance in speed, range and climb rate and the XF-47 could carry a wide inventory of standard weapon and advanced weapon packages devleoped by Stark and the SSR. The XF-47's could operate from land bases or the fleet of SSR Hellicarriers.
A small highly specialized fleet of 34 XF-47's were in the SSR inventory and served in roles from recon, intercept, fighter and ground attack. The XF-47's entered service in 1944 and flew until 1961.
