Some sources state that this is a replica (in which case I wouldn't photograph and upload it), but as far as I can determine it is real. Markings of Marine Fighter Squadron 10 (VF-10M), Naval Air Station San Diego, 1931

This is the only P-23 built. Curtiss retained the last P-6E Hawk (32-278) at their factory, and completed it with a new monocoque aluminum fuselage. Also new were the nose, tail surfaces and landing gear. It was fitted with a turbo-supercharged G1V-1570-C engine with a 3-bladed prop. The new aircraft was delivered on 16 April 1932 and designated XP-23 (Curtiss model 63). It was redesignated YP-23 when the turbo-supercharger was removed. Unfortunately by then the USAAC had lost interest in biplane designs, and no orders were placed. The YP-23 was dropped from USAAC inventory in January 1936. Official USAAC photo.

The F6C-1 was first TOC by the USN in March 1925. Although the contract called for delivery of ten F6C-1, only seven were actually flown as such, with the others modified with tailhooks and designated F6C-2s. These first Hawks participated in early successful trials of dive-bombing, the sturdier metal construction on the leading edge of their wings allowing pilots to dive at angles as great as 70 degrees. The museum's replica example of the F6C-1 was acquired from Chico, California, in 1986.

This Hawk II was built in 1933 and transported by liner SS Europa from the USA to Germany. It firstly became D-3164 and then D-IRIK in April 1934. For the next four years it was the personal plane of the famous Ernst Udet, later Generaloberst of Luftwaffe, and flown during the opening ceremony of the 1936 Olympics in Berlin. After 1937 it was displayed in Herman Göring's private collection, the Deutsche Luftfahrtsammlung, in Berlin but was damaged during an air raid in November 1943. The collection was evacuated to occupied Poland and in 1963 the remnants became part of this great museum.

This P-6E replica was built by Ralph Resnick. Mr. Resnick was able to incorporate surviving wing parts from P-6E S/N 32-260 into his build. This a/c is on display at the EAA Aviation Museum and still has a current FAA registration of N606PE.

This is a 7/8th scale replica built by Donald J Sauser in 1997. It is powered by a Chevrolet V-8 engine.

The NEI army air force bought eight P-6 Hawk I fighters in the USA in 1929. A second batch of eight, including this aircraft, was built by Aviolanda in Holland. Large tropical radiators were fitted. On the fuselage is the name of pilot Sgt Troost. The c/n of this aircraft is incorrectly reported as '32-276'. Photo from: Wereldmuseum

This gem of an aircraft is part of the marvellous Polish Aviation Museum. It flew at the opening of the 1936 Olympics in Berlin.

The 1A "Gulfhawk" is a one-off aeroplane comprising an amalgamation between the Curtiss Navy F6C-4 and the Army P-1 Hawk with a Wright Cyclone engine. The aircraft was primarily used to promote military aviation to the public during the inter-war years and is now on display at the NASM Udvar-Hazy Center.
