NOTE: As was the case with most flying machines around 1910, early Curtiss ships had no particular model numbers or designations. Each was different, modified and custom-built for the buyer with hyphenated names, many were simply generic Curtiss Pushers. When going into production, as such, A-to-C model designations (even some of the first D models) were dealt out with little or no concern about recording specifics, so it was left to post-WW1 historians to make personal guesses as to which was which based on what little data were found. Thanks to the few Aero Club bulletins and fan magazines, some specs and data were recorded; however, most info came from the single most unreliable source of all—newspapers. The mind-boggling technology of aeronautics was played up more for sensationalism than accuracy by reporters who had often never seen an airplane close up or flying over at "breakneck" speeds of 40 mph. Later historians (yes, we're in there somewhere) then faithfully kept replicating those findings until they became accepted as fact when they were actually liberally sprinkled with fancy.

The whole Curtiss group of aircraft is a mixed-up mess! Some planes had major changes and no new type number, while others had a very minor change and received a new type number. Even those who have written books about the company commented about the situation. I found two books about Curtiss airplanes that said two units of one model had been produced, and one had been statically tested to destruction and the other had never flown. The other book said there had been three of those planes ordered, but only two produced, and as the flight characteristics had not been satisfactory they were scrapped—both books were by the same author!

  Curtiss June Bug (post card)

1908 = The AEA Aerodrome #3 as June Bug, used by Curtiss for a total of 32 flights, one of which as the first plane to fly one kilometer, at a recorded 39mph on 7/4/08, for which Curtiss was awarded the Scientific American trophy. It then crashed on 1/2/09 and went into retirement.
1, Golden Flier Gold Bug 1909 = 1pOB; 25-30hp 4-cyl Curtiss water-cooled pusher; span: 28'9" length: 30'4" (?>30'6") v: 45. Glenn Curtiss, based on June Bug. Built for the Aeronautic Society of New York for $5,000 (including pilot training), it was nicknamed "Gold Bug" for its varnish color but had the Society's designation of Golden Flier on 3/2/09. Several more copies were made for ASNY as their Model D, but why that particular designation was used is uncertain.
  Curtiss Rheims Racer (1908 Aerial Age)
  Herring-Curtiss Uncertain reference to that "championship" (1909 Aerial Age)

1, Rheims Racer 1909 = Larger, stripped-down version of Golden Flier with Curtiss 63hp V-8 pusher; span: 34'0" length: 30'4". At Rheims (now Reims) France, flying against the clock, Curtiss set a world's 20-km closed-course record of 43.35 (?>47.06) mph to win the Gordon Bennett Cup, then went on to win events at Brescia, Italy. He also set a speed record of 55 mph at the first US air meet, 1/10-20/10, at Dominguez Hills in Los Angeles. Sold to Charles K Hamilton, who flew exhibitions in it until crashing at Seattle on 3/12/10.
  Curtiss-Herring (Library of Congress Archives)

1909-early 1911 - While A, B, and C models are known (or thought) to have existed during this historically important period for Curtiss, where they were applied is not. Numerical assignments, as well, were guesses—Model 2 has appeared for both Rheims Racer and Charles Willard's Banshee Express but not verified (Willard unjustifiably claimed authorship of that design). By 1910, Model D had been established, in some references tied to Curtiss-Herring, which was actually built after the partners' dissolution. But there were at least 9 aircraft known to have been produced in this period, the "official" Model D, in one of its many forms, formally appeared in the first company catalog on mid-1911 along with its companion Model E. Production of concurrent Curtiss-Aero Society Model Ds unknown but the design quickly evolved into the Curtiss D (Standard). A Herring-Curtiss, for which plans were published for home-builders of the time, differed from Curtiss D with its ailerons on the front wing struts instead of the rear wing struts. Herring's contribution, besides that as a temporary partner, was his alleged invention of a gyroscopic stabilization device (claimed, but unsubstantiated, 1909 US patent #12,256), which would circumvent the Wright's aileron patents, but which was never used on any Curtiss machine.

  Curtiss D Headless Hoisting aboard Pennsylvania (Aviation Heritage)

D (Standard D), D Tractor, D Hydro (San Diego) 1911 = 1pOB and OBF; 35-40hp Curtiss pusher; span: 26'3" to 33'4" length: generally 25'9". This basic tricycle-gear design, a direct descendant of the Model 1 Golden Flier, was continually in development, represented many variations and motors, and gave rise a generic use of the term, "Curtiss Pusher." Other powerplants went up to 75hp, and within this major design came Roman-numeral variations. D-II had a single front elevator, double-surfaced wings with ailerons mounted on the rear of the wing struts. D-III (D Tractor) with 60hp Curtiss V-8 was for USN evaluations, modified into a tractor configuration with a pilot's seat aft of the motor, had interconnected elevators front and back, shortened front booms and the planes moved inward, and was the transition to the long-wing Headless. It also was the first airplane to fly (SEE comment below) to and from the deck of a ship (cruiser USS Pennsylvania,) on San Francisco Bay, 1/18/11 (p: Eugene Ely), and the first aircraft to be hoisted aboard a ship (USS Pennsylvania,) on 2/17/11, in San Diego (p: Curtiss). D-IV eliminated all the forward booms and evolved into D-V as the military "war" machine (51hp V-8), with the USN its principal buyer. D-III [AS2] and D-IV were the first Curtiss machines purchased by the Army, in March 1911. One modified as Curtiss Triplane. SEE ALSO 2, Rheims Racer above, Curtiss Sales Booklet, and Curtiss Boats

[About Curtiss' hoisting demonstration aboard USS Pennsylvania on 2/17/11 with his float-modified D Headless as flying boat]: Most accounts tell of Curtiss taking off and flying to the cruiser amidst ringing bells and blowing whistles, then flying back to camp after the hoist demonstration. The fact is Curtiss had never flown that plane as a tractor and when he took off, it leaped into the air alarmingly. He cut the throttle, and the plane hit the water with a resounding "smack!" Fortunately, the hull did not split, as they were known to do, and Curtiss proceeded to the hoisting demonstration as recorded, but on the surface. [Curtiss taxied from his camp at North Island to the ship and back.] The airplane never flew again. (— Waldo Waterman)
  Curtiss D (Museum of Flight)

D Flying Boat (San Diego) 1912 = 2pOBFb; 60hp Curtiss V-8 and two chain-driven tractor propellers; span: 33'4" v: 60. Long-hulled (20') seaplane had an electric starter. Technically the world's first flying boat (conflicting with D Hydro's flight in 1911), although its performance was marginal at best and overshadowed by the 1912 E Flying Boat; ff: 1/10/12 (p: Curtiss). POP: 1, although a non-flying prototype might have been built previously at Hammondsport and another at San Diego as prototype USN flying boat.
D Hydroaeroplane SEE D-8.
D-2 Canoe Machine, D-4 Headless (San Diego) 1910 = 1pOBFb; 33-40hp 4-cyl Curtiss pusher; span: 33'4" length: 25'9". The first of Curtiss' production seaplanes was built around a hull designed by F W Baldwin. The plane never flew and, after May 1910 taxi tests, the project was shelved to concentrate on production aircraft. The hull was shipped to San Diego in Nov 1910 for further testing as D-4, which evolved into D-8.
  Curtiss D Hydro Preparing for first flight from water at San Diego, 1911 (postcards)
D-8 Canoe Machine, D Hydro (San Diego) 1911 = 1p headless OBF; 60-75hp Curtiss V-8 pusher; span: 26'3". Standard D converted to a seaplane with a large main float and wingtip stabilizing pontoons. Modified with retracting wheels as Triad. Evolved into D Hydro. Using spruce pontoons built by Baker Machine Co, San Diego, and knowledge acquired at AEA, Curtiss finally succeeded in a water take-off and landing in San Diego harbor on 1/26/11, and is credited with being the first to do so, at least in this country. There is contention over Curtiss' international claim as Henri Fabre had accomplished a water take-off in his Hydroavion canard monoplane on 3/28/10, at Martigues, France, a feat documented by a photograph and an eyewitness report that Fabre's machine rose to about 60' above the surface for a distance of about 1,600'. However, his airfoil pontoons prevented a water landing, so it seems that credit should at least be shared with Curtiss.

[About Curtiss' unsuccessful first attempts to take off from the ocean in his float-converted D-8 landplane] ... It was not that the wheels were too heavy, but that they did not retract and their drag in the water prevented flying speed attainment. As a matter of fact, the [subsequent] retractable wheel combination was the heavier of the two. (— Waldo Waterman)

E-75 1911 = Hydro with detachable 16' float ($6,000) became the A-1, which was accepted in 1911 by USN as their first aircraft; 60hp Curtiss S-6; span: 36'11" length: 31'8" v: 44. POP: 3. A-2, AX-1 and E-1 models soon followed.

  Curtiss E Flying Boat Possible C-1 (postcard)
  Sperry-Curtiss E
  Curtiss E Flying Boat Curtiss School dual trainer with Ray Morris (l.) and Beckwith Havens (r.) (Curtiss Museum)

E Flying Boat 1912 = 2-3pOBFb; 80-100hp OX pusher; span (typical): 37'0" length: 27'9". Credited as being the world's first successful flying boat, although it was actually preceeded by the D Flying Boat. 26' wood hull had six watertight bays; Standard E wings with added diagonal extensions to the tips; small interwing ailerons. Often mistakenly identified as an early version of F, many design variations appear, some with spans to 40'—the Marshall Reid model (SEE following) had bowed-out cockpit sides to facilitate shoulder-yoke movement of the ailerons; the Lawrence Sperry model (aka Sperry-Curtiss E) had a Sperry-designed retractable beaching gear and a huge, bulbous nose; Jack Vilas' 400-mile-range Special had 40'0" top wing and 31'3" lower wing, length: 26'0", and a 90hp OX; the "School Machine" had a folding boarding ramp built into its nose, and a bilge pump (this plane is in the NASM collection); the $6,000 "Sport Boat" seated three and had the 80hp Curtiss OX. Later models were fitted with the diagonal Goodier strut from top wing to front of cockpit to prevent the motor from tumbling into the cockpit in case of a "strong" landing.

Bowers claims that there was no such model as a Curtiss Model E flying boat, but Louis Casey's book on the early, mostly Hammondsport-built, models calls this one the 1913 Curtiss E Flying Boat. He gives extensive photographic coverage, including the one built for a Marshall Reid, with a shot of Reid in his boat on a dock at Hammondsport. (— Jack Erickson 9/15/00)

Until 1914 the F-boats were in "the development stage," as were most of the Curtiss machines of that period. In 1914 it became necessary to "standardize" in anticipation of military orders. The only E-boat was the first successful flying boat that had the same wing panels as the landplane and hydroplane E models; after that the spars were continuous from hull to tip, not separate sections as in the E. The triangular panels that seem to cause so much confusion were optional add-ons until the dimensions of the wing panels became standardized for the later 1914 F-boats. (— Lew Casey 8/18/02)

Built for retailer Rodman Wanamaker to compete for London Daily Mail £10,000 prize for first transatlantic flight, but the event was cancelled by WW1. The world's first two-motored flying boat was tried with a third OX-5 atop the wing center-section, but that proved impractical. $25,000; POP: 1.
H-2, H-4 America (Model 6) 1914 = Export version of H-1. POP: 1 H-2 and 11 H-4 to British Admiralty, with 4 of the latter assembled in England by S E Saunders Co, plus a second order for 50 more in 1915. Design led to British and Canadian license-built Felixstowe F.5L design.
H-8 1916 = Larger 4p version of H-4 with 160hp Curtiss was prototype for USN H-12. POP: 1, sold to Fleet Air Arm.
  Curtiss H-10 Hull assembly line (clip: Apr 1916 Flying)

H-10 1916 = OBFb, larger than H-8. Info on this model was sketchy and it is speculated that the attached photo, showing a more snub-nosed hull than appeared on other H-boats, is likely our mystery ship.
  Curtiss H-12

H-12 (Model 6A) 1916 = 4pOBFb; originally two 160hp Curtiss VX-X pushers, replaced by 200hp V-2-3, finally 330hp Liberty 12 (a few experimental tractor mods reported); span: 92'9" length: 46'6" load: 2044# v: 85/x/55 range: 450 ceiling: 10,800'. POP: 19 for USN [A152, A765/783].

H-12B (Model 6D) 1918 = H-12 and H-12A exports with 375hp R-R Eagle VIII pushers. POP: 24.

H-12L 1918 = USN remainders refitted with 360hp Liberty 12 pushers. Last planes withdrawn from service in mid-1920.

H-14 - Smaller twin pusher version of H-12. Army contract for 16 cancelled in 1916 after s/ns had been applied [396/411]. However, in mid-1917, the unfinished prototype was completed for USN as a single 200hp Curtiss VX-3 pusher as HS-1, and it and the remaining contract were finished and delivered [A800-815].
  Curtiss H-16 [A-853]

H-16 (Model 6C) 1917 = An even larger version of H-12 with 400hp Liberty 12 pushers, longer wings and balanced rudder; span: 95'1" length: 46'2" v: 95/x/56 range: 380 ceiling: 9,950'.

POP: 1 prototype HA [A2278], Protoype was so tail-heavy that Rohlfs landed with a series of swooping stalls to a crash-landing that ostensibly destroyed the plane. SEE Flying the HA
HA-1 = 2pOBF. First HA-1 was redesigned and rebuilt using salvaged parts of HA, but second HA-1 had completely new wings. $42,900; POP: 2 production HA-1 [A4110/4111]. The former caught fire in flight, was sucessfully landed but lost in unsuing flames.

  Curtiss BT (Peter Bowers coll)

HA-2 = Modification of HA-1 [A4111] with two-bay wings and cabane struts; span: 42'0" length:30'9" v: 128.

Hawk IV (Model 79) 1936 = 745hp Wright R-1829; length: 23'6" v: 249/211/x range: 577 ceiling: 30,300'. POP: 1 [NR188M] exported to Argentina.
Headless 1912 = A modified Standard-D, said to have come about when exhibition pilot Lincoln damaged the front booms and elevators on a landing during a show and, averse to losing money by cancelling the show, removed the debris to continue flying with only tail elevators. In so doing he noticed an improvement in performance and agility. When news of this reached Curtiss, design changes were soon implemented in the D-III models. SEE D (Standard-D). Clipped-wing Headless Racer, with 75hp Curtiss V-8 (span: 17'3" length: 26'1" v: 85), was used by in the 1912 Bennett Cup races. A tractor biplane designed for Beachey by Curtiss failed to impress him—SEE Curtiss-Beachey.
HS (Model 8) - USN patrol boat, very similar to MF. 2-3pOBF; 350-360hp Liberty 12 pusher; span: 74'1" length: 39'0" v: 83 ceiling: 5,200' (data for HS-2L).
HS-1, -1L 1917 = H-14 prototype with 200hp Curtiss VX-3 (aka VXX) pusher; span: 62'1" length: 38'6" ceiling: 2,500'. POP: 16 from a cancelled Army contract [A800-815], refitted with 360hp Liberty 12 as HS-1L.

HS-2L 1917 = POP: 659 [A1549/2207], plus those manufactured at Naval Air Stations (6 at Miami [A5564/5569], 4 at NAS Hampton Roads [A5615/5618], 3 at San Diego [A6557/6559], 1 each at Key West [A5787], Anacostia [A5808], and Coco Solo [A6506]), and built under contract: 25 by by Boeing [A4231/4255], 60 by Gallaudet [A2217/2276], 300 by L-W-F [A1099/1398], 2 by Loughead [A4228/4229], 7 by NAF [A6507/6513], and 80 by Standard [A1399/1478]. About 12 were assembled from spare parts after the war.

HS-3 1919 = Modified hull, assembled from spare HS-2L parts; span: 75'6" length: 38'7" v: 89 ceiling: 6,500'. POP: 4 [A5459/5462], plus 2 by Naval Aircraft Factory [A5590/5591].

  Curtiss J Prototype (Curtiss)
  Curtiss JN-1 [AS-30] (Curtiss)
  Curtiss JN-1S or -1W US Navy

J, JN (Buffalo) 1914 = 2pOB and OBF; various 90-160hp Curtiss OX/OXX; span: 30'0" (40'2" top wing on float version) length: 26'4" v: 84. Benjamin Douglas Thomas (formerly with Sopwith Ltd, later with unrelated Thomas Bros). Sopwith and Avro influence is apparent, and the shape of JN-4 was becoming noticeable. POP: 2 for Army evaluation [AS29/30], the latter redesignated as JN-1, and 2 with floats to USN as JN-1S or -1W [A149/150].
Janin Patent Boat 1918 = 1pOBFb; two pushers. A curiosity in that it was built to prove it would not fly. This all came about because of a 1914 lawsuit by Albert Janin, claiming patent infringement (1913 US patent #1,312,910), that led to Curtiss building one plane embodying Janin's idea. Sure enough, it failed to fly, and Curtiss eventually won the case.
  Curtiss JN-2 [42] (USAS via B C Reed coll)

JN-1, -2, -3 1915 = JN-1 was a redesignation from the second of the prototypical J models [AS30], 30'0" equal-span wings with upper-wing ailerons, shoulder-yoke aileron control, skidless landing gear; v: 75/60/43 ceiling: 6500'. POP: 3 to USN as J-1 [A198/200], 8 as JN-2 [AS41/48], of which 5 were later refitted with JN-3 wings [A41/44, A48]. 1st Aero Sqn use in 1916 Border War against insurgent Pancho Villa.
JN-3 1915 = As previous, not quite yet a "Jenny;" span: (top) 40'0" (bottom) 30'0". Deperdussin control system; top-wing ailerons run by a steering wheel. POP: 2 for Army [AS52/53], 91 exports to Great Britain; about 100 more were built in Canada for shipment to RNAS, with 12 of them from Curtiss' branch fctory in Toronto. Serving in Border War, [AS52] suffered forced-landing at Ojito, Mexico, and was abandoned.
  Curtiss JN-4 at Hotel Clarendon, Daytona Beach FL (TKnL coll)

JN-4, -5, -6 "Jenny," JNS, JN-4CAN (Buffalo, Toronto) - 2pOB; 90hp Curtiss OX-5; span: 43'7" length: 27'4" load: 500# v: 75/59/45 range: 150 (specs from a 1920 Curtiss pamphlet). B D Thomas. Famed military series, a blending of the J and N models, "Jenny" was an unofficial nickname. Suffix "S" indicated twin-float version. More than 8,000 were produced at a unit costs from $4,200 minus engine to $8,160 with engine, and many of those ended up selling for $300-1,500 as war surplus. As JN-4CAN Canuck (also Cannuck), it was built in Toronto under license by Canadian Aeroplanes Ltd, a visible difference being two extra ailerons. Our "Jenny" listings include only production aircraft by Curtiss Co and its licensees, and omit rebuilds and mods of hundreds of those sold surplus which appear on registers with proprietary (or even "Curtiss") names and generally with a "sub" c/n—eg: "Curtiss JN-4C Special" was a surplus Jenny bought by a Mr Larsen of Chicago, sold to Charles Ullom, who had it modified in 1927 by Partridge & Keller as the clipped-wing "Special" with enlarged fuel tank and lengthened struts [1221] c/n U-5442sub. SEE ALSO Hopeless Hints for Jenny Drivers.
  Curtiss JN-4 (postcard)

JN-4 1916 = Primary trainer with Deperdussin controls. 90hp OX-5. Took part in the Mexican Border War as the USA's first aircraft (with JN-3) in military combat, such as it was. $7,750-8,160; POP: 380 (>603, >94) [AS76/81, AS120/125, AS130/136, AS318/319, AS408/427, AS443/446, AS468, AS682/699, AS731/991, AS1200/1212, AS1301/1309, AS2265/2266, AS12876], and 11 to USN [A149/150, A388/389, A995/997]. NOTE: serials need clarifying since these were recorded from several different sources.

JN-4A (Model 1) 1917 = Down-thrust motor, revised wings with added dihedral, four ailerons, enlarged tails. 90hp OX-5. $8,160; POP: 366 [AS541/556, AS1057/1199, AS1213/1282, AS1527/1656, AS2519/2524, AS3925].

  Curtiss JN-4C Modified for Frank Clarke [412K] (Paul Chesebrough)

JN-4C 1916 = Experimental wings with ailerons on top wing only. 90hp OXX-3. POP: 2 [AS471/472].

JN-4(Can) (Canada) 1917 = Canadian Aero production as JN-4(Can) was independent of Curtiss and a direct evolution from JN-3 with considerable refinements—metal empennage frame, four ailerons, and a cockpit stick control among them. Exact total Canadian JN-4 production is unknown as many unfinished Curtiss JN-4As were completed in Toronto and many others had Canadian JN-4 wings. To add to that can of worms, because of different aircraft modifications and tallying systems, a JN-4(Can) in US Army service often became shortened by scribes to JN-4C, giving rise to some confusion about correct designations. On the field level, pilots and ground crews dubbed them "Canucks," a nickname that lasted well into post-war years. A popular guesstimate is 1,260 JN-4s, 87 JN-4As, plus many built from spares, for a total of 1,611 Canadian-built planes. $4,250 less engine; POP total JN-4(Can) for USAS: 400 [AS38533/38632, AS39062/39361].

JN-5H 1918 = Conversion of JN-4H [AS38124] as prototypical advanced trainer, reserialed as [AS41358]. Equal-span wings, revised tail shape. It subsequently was returned to its original JN-4 configuration and handed over to McCook Field for testing as their designated P-24, where it gained steel-framed wings, a 180hp Wright-Hisso with controllable-pitch prop, and a steerable tailskid. Destroyed in a crash 8/18/20. NOTE: This was also a first "paper" designation for Curtiss JN Twin.
