The latest version of the Hawkeye is the E-2D, which began operations in 2010. The E-2 was the first aircraft designed specifically for its role, as opposed to a modification of an existing airframe, such as the Boeing E-3 Sentry. Variants of the Hawkeye have been in continuous production since 1960, giving it the longest production run of any carrier-based aircraft. This shirt is designed, printed and shipped directly from the U.S.A to anywhere in the world (including APO/FPO bases).
