This is a list of auxiliaries of the United States Navy. It covers the various types of ships that support the frontline combat vessels of the United States Navy. Auxiliary ships which function as hospital ships and as oilers are to be found in their own articles: List of United States Navy hospital ships and List of United States Navy oilers. Escort carriers, amphibious warfare vessels, and some mine warfare vessels were also originally classed as auxiliaries but were later given their own hull classification symbols outside the auxiliary series (which all begin with an 'A'). Links to these and other list articles of similar ships can be found throughout this article. Yard and district craft also function as auxiliaries but generally are smaller and less capable than their ocean-going counterparts, and so they generally remain in harbors and coastal areas.

Their hull classification symbols begin with a 'Y'. Ship status is indicated as either currently active [A], ready reserve [R], inactive [I], or precommissioning [P]. Ships in the inactive category include only ships in the inactive reserve, ships which have been disposed from US service have no listed status. Ships in the precommissioning category include ships under construction or on order. Listed ship classes will often state 'MA type' or 'MC type'. The difference is that 'MC Type' refers to ships designed by the United States Maritime Commission aka MarCom, while 'MA Type' refers to ships designed or converted under MarCom's successor agency, the United States Maritime Administration or MarAd. They are in fact the same designs, and the year 1950 is the date at which MarAd succeeded MarCom.

The Focke-Wulf Fw 190, nicknamed Würger (Shrike) is a German single-seat, single-engine fighter aircraft designed by Kurt Tank at Focke-Wulf in the late 1930s and widely used during World War II. Along with its well-known counterpart, the Messerschmitt Bf 109, the Fw 190 became the backbone of the Jagdwaffe (Fighter Force) of the Luftwaffe. The twin-row BMW 801 radial engine that powered most operational versions enabled the Fw 190 to lift larger loads than the Bf 109, allowing its use as a day fighter, fighter-bomber, ground-attack aircraft and to a lesser degree, night fighter. The Fw 190A started flying operationally over France in August 1941 and quickly proved superior in all but turn radius to the Spitfire Mk. V, the main front-line fighter of the Royal Air Force (RAF), particularly at low and medium altitudes. The 190 maintained its superiority over Allied fighters until the introduction of the improved Spitfire Mk. IX. In November/December 1942, the Fw 190 made its air combat debut on the Eastern Front, finding much success in fighter wings and specialised ground attack units (Schlachtgeschwader – Battle Wings or Strike Wings) from October 1943. The Fw 190A series' performance decreased at high altitudes (usually 6,000 m [20,000 ft] and above), which reduced its effectiveness as a high-altitude interceptor.

From the Fw 190's inception, there had been ongoing efforts to address this with a turbosupercharged BMW 801 in the B model, the much longer-nosed C model with efforts to also turbocharge its chosen Daimler-Benz DB 603 inverted V12 powerplant, and the similarly long-nosed D model with the Junkers Jumo 213. Problems with the turbocharger installations on the -B and -C subtypes meant only the D model entered service in September 1944. These high-altitude developments eventually led to the Focke-Wulf Ta 152, which was capable of extreme speeds at medium to high altitudes (755 km/h [408 kn; 469 mph] at 13,500 m [44,300 ft]). While these "long nose" 190 variants and the Ta 152 derivative especially gave the Germans parity with Allied opponents, they arrived too late to affect the outcome of the war. The Fw 190 was well-liked by its pilots. Some of the Luftwaffe's most successful fighter aces claimed many of their kills while flying it, including Otto Kittel, Walter Nowotny and Erich Rudorffer. The Fw 190 had greater firepower than the Bf 109 and, at low to medium altitude, superior manoeuvrability, in the opinion of German pilots who flew both fighters. It was regarded as one of the best fighter planes of World War II.
