Nicaraguan Air Force (FAGN) officers received a royal blue US Air Force-style M1947 service dress, worn with a light blue shirt and royal blue tie on formal occasions; a short-sleeved shirt and matching royal blue sidecap (a.k.a. 'flight cap') was worn by officers and other ranks in active service. The Nicaraguan Navy retained both the white dress and khaki uniforms, with officers' adopting a modified version of the M1942 tunic with removable shoulder boards, which was worn with a light khaki shirt and black tie on service dress.
