Most saw service as part of the [[United States Army Air Corps]] as observation aircraft with the designations '''O-1''' and '''O-11''', or as the attack aircraft designated the '''A-3 Falcon'''. [[United States Navy|U.S. Navy]] variants were used initially as fighter-bombers with the designation '''F8C Falcon''', then as the first [[United States Marine Corps|U.S. Marine Corps]] [[dive bomber]]s with the name '''Helldiver'''. Two later generations of Curtiss dive-bombers were also named [[Curtiss Helldiver (disambiguation)|Helldiver]]<!--intentional link to DAB page-->. The type was introduced in 1925 and saw first-line service in the United States until 1934. Curtiss Falcons fought in the [[Constitutionalist Revolution]] of 1932 in [[Brazil]], used by the forces of [[São Paulo]]. ==Design and development== The '''Falcon XO-1''' [[prototype]] was evaluated by the USAAC along with eleven other prototypes in 1924 and the [[Douglas O-2|Douglas XO-2]] was declared the winner of that competition. So Curtiss re-engined the prototype with the [[Packard 1A-1500]] for the 1925 trials, which it won. The engine failed to live up to expectations and the '''O-1''' ordered by the Army was fitted with the 435 hp (324 kW) [[Curtiss V-1150]] (D-12) engine.<ref name="ohnine"/> The aircraft was a conventional unequal-span biplane design with wooden wings, while the [[fuselage]] was built using [[aluminum]] tubing with steel tie rod bracing.<ref name="world">{{cite book |editor1-last=Eden |editor1-first=Paul |editor2-last=Moeng |editor2-first=Soph |title=The complete encyclopedia of world aircraft |date=2002 |publisher=Barnes & Noble Books |location=London, NI 9PF |isbn=0-7607-3432-1 |page=cover}}</ref> The [[landing gear]] was fixed and the [[Empennage|tail]] included a [[balanced rudder]] with a rear skid originally, later changed to a tailwheel.{{Citation needed|date=January 2021}} The initial A-3 Falcon order was placed in the winter of 1927 and delivery of the first plane was in October 1927. A total of 76 A-3s were received. Later, six aircraft were modified as pilot trainers with dual controls and redesignated A-3A. A second batch of 78 improved A-3Bs, based on the Curtiss O-1E, was purchased beginning in 1929.{{Citation needed|date=January 2021}} ==Operational history== {{More citations needed section|date=January 2021}} [[File:Curtiss OC-2.jpg|thumb|Curtiss OC-2s in flight, c. 1929]] Reasonably successful as an observation aircraft, Falcons flew primarily in the [[1st Reconnaissance Squadron|1st]], 5th and 99th Observation Squadrons of the [[9th Bomb Group|9th Observation Group]], [[Mitchel Field]], [[New York (state)|New York]]. The A-3 Attack Falcon saw considerable use, in first-line service with the 8th, 13th and 19th Attack Squadrons of the 3rd Attack Group, [[Barksdale Air Force Base|Barksdale Field]], [[Louisiana]], and the 26th Attack Squadron in [[Hawaii]] from 1928 to 1934 and second-line service with reserve units until 1937. The U.S. Navy introduced the F8C-1 and F8C-3 Falcon as a shipboard fighter in 1927–1928. They were later redesignated OC-1 and OC-2 for Marine Corps use as an observation/bomber. The F8C-4 Helldiver variant initially saw service with the Navy, and the first production batch of 25 was transferred in 1931 to the Marine Corps. A total of 34 F8Cs redesignated as O2C-1 observation aircraft were also transferred to the Naval Reserve in 1931, serving with squadrons VN-10RD9, VN-11RD9, and VN-12RD9. Most of the 63 newer F8C-5/O2C-1 Helldivers also served with the Marines, remaining in service until 1936. The type was featured in multiple Hollywood films: ''[[Flight (1929 film)|Flight]]'' (1929), ''[[Hell Divers]]'' (1932) and ''[[King Kong (1933 film)|King Kong]]'' (1933). Two non-flying replicas were built for ''[[King Kong (2005 film)|King Kong]]'' (2005) Curtiss Falcon aircraft fought during the [[Brazil]] [[Constitutionalist Revolution]] of 1932, under the flag of [[São Paulo (state)|São Paulo]]. In [[Bolivia]], the aircraft type also fought in the [[Chaco War]] (1932–1935), bombing [[Paraguay]]an troops.<ref name="Hagedorn">{{cite book |last1=Hagedorn |first1=Dan |last2=Sapienza |first2=Antonio Luis |title=Aircraft of the Chaco War |date=2000 |publisher=Schiffer Pub |isbn=0-7643-0146-2 |page=144}}</ref><ref name="Corum">{{Cite journal |last=Corum |first=James S. |date=3 February 2003 |title=O Poder Aéreo na Guerra do Chaco |trans-title=Air Power in the Chaco War |url=http://www.airpower.maxwell.af.mil/apjinternational/apj-p/2003/1tri03/corum.html |url-status=dead |journal=Air & Space Power Journal |language=pt |archive-url=https://web.archive.org/web/20170218063524/http://www.airpower.maxwell.af.mil/apjinternational/apj-p/2003/1tri03/corum.html |archive-date=18 February 2017 |access-date=12 April 2019}}</ref> The [[Colombian Air Force]] used Falcon F-8 and O-1 in the [[Colombia-Peru War]] in 1932–3. ==Variants== <sub><ref name="world" /></sub> ===U.S. Army Air Corps=== ;A-3: Model 44, [[attack aircraft]] version of O-1B, armed with two 0.30 in (7.62 mm) machine guns and 200 lb (91 kg) of bombs; 66 built for the USAAC. ;A-3A: Six A-3s converted into trainers. ;A-3B: Model 37H, attack version of O-1E, with six machine guns, including two mounted in wings; 78 built.
