Yes, guided missiles, aircraft carriers and submarines.
World War II
 The use of the jet aircraft was pioneered and, though late introduction meant it had little impact, it led to jets becoming standard in air forces worldwide. Although guided missiles were being developed, they were not advanced enough to reliably target aircraft until some years after the war.

Advances were made in nearly every aspect of naval warfare, most notably with aircraft carriers and submarines.

World War II [SEP] Advances in technology and warfare
Many means of destroying tanks, including indirect artillery, anti-tank guns (both towed and self-propelled), mines, short-ranged infantry antitank weapons, and other tanks were used. Even with large-scale mechanisation, infantry remained the backbone of all forces, and throughout the war, most infantry were equipped similarly to World War I. The portable machine gun spread, a notable example being the German MG34, and various submachine guns which were suited to close combat in urban and jungle settings. The assault rifle, a late war development incorporating many features of the rifle and submachine gun, became the standard postwar infantry weapon for most armed forces.
