Captain America has used multiple shields throughout his history, the most prevalent of which is a nigh-indestructible disc-shaped shield made from an experimental alloy of steel and the fictional vibranium.[140][141] The shield was cast by American metallurgist Dr. Myron MacLain, who was contracted by the U.S. government, from orders of President Franklin Delano Roosevelt, to create an impenetrable substance to use for tanks during World War II.[140] This alloy was created by accident and never duplicated, although efforts to reverse-engineer it resulted in the discovery of adamantium.[142]
Captain America often uses his shield as an offensive throwing weapon. The first instance of Captain America's trademark ricocheting shield-toss occurs in Stan Lee's first comics writing, the two-page text story "Captain America Foils the Traitor's Revenge" in Captain America Comics #3 (May 1941).[13] The legacy of the shield among other comics characters includes the time-traveling mutant superhero Cable telling Captain America that his shield still exists in one of the possible futures; Cable carries it into battle and brandishes it as a symbol.[143]
When without his trademark shield, Captain America sometimes uses other shields made from less durable metals such as steel,[144] or even a photonic energy shield designed to mimic a vibranium matrix.[145] Rogers, having relinquished his regular shield to Barnes, carried a variant of the energy shield which can be used with either arm, and used to either block attacks or as an improvised offensive weapon able to cut through metal with relative ease.[146] Much like his vibranium shield, the energy shield can be thrown, including ricocheting off multiple surfaces and returning to his hand.[147]
Captain America's uniform is made of a fire-retardant material, and he wears a lightweight, bulletproof duralumin scale armor beneath his uniform for added protection.[56] Originally, Rogers' mask was a separate piece of material, but an early engagement had it dislodged, thus almost exposing his identity. To prevent a recurrence of the situation, Rogers modified the mask with connecting material to his uniform, an added benefit of which was extending his armor to cover his previously exposed neck. As a member of the Avengers, Rogers has an Avengers priority card, which serves as a communications device.
Captain America has used a custom specialized motorcycle, modified by the S.H.I.E.L.D. weapons laboratory, as well as a custom-built battle van, constructed by the Wakanda Design Group with the ability to change its color for disguise purposes (red, white and blue), and fitted to store and conceal the custom motorcycle in its rear section with a frame that allows Rogers to launch from the vehicle riding it.
