  Aeromarine Flying Boat (Aerial Age via Joe Martin)

c.1909 = Aeromarine's first effort, a 1p canard pusher flying boat. No information found.

1923 = 1pOB; 400hp Liberty 12. Paul Zimmerman. Mail carrier with an all-metal fuselage covered with sheet aluminum, the first of its kind in the US. POP: 1. Possibly was AM-1.
  Aeromarine 8 (Aviation via Joe Martin)

8 c.1910 = 2pOB; pusher motor. Canard stabilizers with twin rudders between the wingtips.
20 1918 = 2-4pOBFb; pusher motor. Charles Willard.
  Aeromarine 39-A (Leo Opdyke coll)

39-A 1917 = USN scout and trainer. 2pOB (land and seaplane); various motors: Aeromarine, Beardmore, Hisso, OX-5, OXX-6; span: 47'0" length: 30'4" v: 72. POP: 50 with 100hp Hall-Scott A-7 [A450/499]. Purchased by USN for $9,688, sold surplus in 1921 for $1,500, reduced to $800 in 1928; about 30 of these were located in registers.
  Aeromarine 39-B (Peter M Bowers coll)

39-B 1921 = 100hp Curtiss OXX; span: 47'0" length: 30'5" v: 68. First airplane to make a landing aboard what could be called an aircraft carrier (USS Langley) on 10/26/22 (p: LtCdr Godfrey Chevalier). $9,650; POP: 150 [A500/649].

Photo is of a 39B probably contract-built for USN during WW1. The float bracing arrangement (possibly to facilitate torpedo or bomb carriage), aileron shape, kingpost wing supports, and trestle cabane combine to virtually guarantee this ID. On the other hand, Aeromarine 39s seem to have been powered by a bewildering series of engines, including some of Aeromarine's own. I'm not sure if this powerplant is one of theirs, a Curtiss OX, a Hispano, or something else. (-- Bill Devins 2/4/01)

39-R 1921 = $10,300; POP: 14.

Spruce I-beam spars and ribs, dural-framed empennage; fabric-covered wings and tail; all-duraluminum hull. Designed to replace the aging 75s of Aeromarine Airways. AMC = "Aeromarine Metal Commercial."
  Aeromarine AMC? (Aviation via Joe Martin)

Long before Macintosh and Photoshop, this bit of "creative enhancing" asks more than it tells. It could be a short-wing version of AMC, dubbed Morro Castle II, but its placement in an Egyptian setting is a mystery—perhaps for an ad with a relevant headline. The plane appears to be pasted on the background—a small seam below the rudder hinge is visible. If it is supposed to be landing, it is doomed. The prop is stopped and the pilot sits on the coaming away from the controls, which are set for a severe left hand dive into the Nile, or whatever. It could be slung from a crane or gantry with the ropes retouched out, but if some viewer has info of what this was all about, we would appreciate learning of it. (— K O Eckland 3/4/03)
  Aeromarine AS-1 [A-5612] (NASA)
  Aeromarine AS-2 [A-5613] (1922 Aircraft Year Book)

AS-1, -2 1920 = USN scout-observation. 2pOBF; 300hp Hisso; span: 37'6" length: 30'6" v: 117 ceiling: 16,000'. Twin floats. $18,450; POP: 1 AS-1 [A5612], 2 AS-2 in 1921 [A5613/5614].
BM-1 Mail Plane 1924 - 1pOB; 400hp Liberty 12; span: 47'0" length: 22'0". Scheduled, but not built. Some sources claim one built, but unregistered.
CO-L 1924 - Army observer. 2pOB; 400hp Liberty 12;span: 39'0" length: 28'0". None built.
  Aeromarine DH-4B Wright Field P-292 [AS22-1128]

DH-4B 1918 = Contract-built British de Havilland scout-observation. POP: 125.
  Aeromarine EO (Aviation via Joe Martin)

EO 1924 = 3pOBFb; 80hp Anzani 6-A3; span: (upper) 38'0" (lower) 34'0" length: 25'2". Earl D Osborne. Aluminum hull. POP: 1 [784]; a reported second one might have only been a modification to a larger fin, and with increased dihedral. Details on this one are quite fuzzy. [1791], registered as a 1924 Anzani-powered Aeromarine biplane (no mention of floats), license applied for Sep 1927, is noted as sold to EDO Corp in Apr 1924 (it is thought this aircraft had an original IMA registration [747]). A second, [1791], shows a 1926 semi-cantilever 4pOhw MFb EDO Model B, also with 80hp Anzani, license also applied 9/14/27, but is said to have first had IMA [32], later changed to [598] for unstated reasons. If this wasn't bad enough, in response to a 1928 CAA inquiry, EDO replied they had no airplane registered [1791], only two flying boats, [32] and [784], but the latter is in registers both as Aeromarine-Klemm EO and EDO Seaplane. It didn't help when c/n 10068 was arbitrarily reassigned in 1929 by its purchaser, American Aeronautical Corp, to replace Aeromarine's c/n 1, and a 90hp Kinner installed, to become [NC784]. Wherever the path of EO went, it eventually led to its demise in a crash at Cape May NJ on 12/15/31.
  Aeromarine HS (1922 Aircraft Year Book via Joe Martin)

HS 1921 = Aeromarine conversion of surplus Curtiss HS-2L open cockpit flying boat, using the wings and engine structure with an Aeromarine hull. POP: possibly only one. Lady Baltimore II pictured here was the short-lived Easter Airways' plane, displaying part of a commercial "FOR NEURALGIA" message on the underside of its top wing... an additional source of revenue.
L-20 (Boland ) 1928 = 2pOlwM; 20hp Mercedes; span: 38'0" v: 80/66/20. Hans Klemm (Germany), from his 1923 design, Klemm-Daimler L.20 (aka D-M-G L.20). All-wood construction, part fabric-covered wing. Pivoting wingtips for ailerons, later replaced by conventional ailerons. POP: 1 for design evaluation [867W]. Others registered under the Klemm title [eg: 4919, 4920], with Mercedes motors, are probably German imports of an earlier date.
L-25 (Boland ) 1928 = 2pOlwM; 40hp Salmson AD-9. Hans Klemm, from his German powered glider design, L.25. POP: 1 prototype [possibly 628], plus several registered as Leicht-flugzeugbau L-25 [10051, et al]. Design became production Aeromarine-Klemm AKL-25-A.
LDB 1923 - Army bomber design with 115'0" wing and 65'0" airfoil fuselage. Two designs, but neither known built.
  Aeromarine M-1 (Leo Opdyke coll)

M-1 1917 = Advanced trainer. 2pOB; Hall-Scott A-7A; span: 37'3" length: 25'11". POP: 6 [AS265/270].
Messenger 1924 = 1pOB; Lawrance L-4; span: 20'0" length: 17'9". Experimental variable-chord wings. POP: 1.
NBS-1 1921 = Contract-built Martin MB-2. POP: 25 [22-201/225].
  Aeromarine PG-1 [AS64245] (Leo Opdyke coll)

PG-1 1922 = Army ground-attack pursuit. 1pOB; 330hp Wright K-2, later 350hp Packard 1A-1237; span: (upper) 40'1" (lower) 37'2" length: 24'6" load: 888# v: 130/124/58 range: 195 ceiling: 17,000'; ff: 8/22/22. Built by Engineering Division and Boeing, it had a 37mm cannon in its propshaft and lots of armor plate. Ultimately rejected because of pilot's lack of forward visibility. POP: 3 [AS64245/64247], the first to McCook Field as project P-240. The only pursuit aircraft with a "PG" designation, which was later transferred to the Powered Glider category.
Sea Scout c.1922 = USN 1pOBF. No data, possibly rejected by Navy.
Seaplane c.1916 = USN; no data. POP: 3 [A439/441].
Sportsman 1917 = 2pOB; 100hp Aeromarine V-8; span: 47'0" length: 26'8" load: 700# v: 78/x/48. Vincent Burnelli. Civil version of Aeromarine 39-B. POP: 1. Refitted with floats, it made the first aerial delivery of mail to a ship at sea on 8/14/19.
Type XII Night Bomber 1924 - OB; four engines in push-pull configuration. Not built.
Type XIII Night Bomber 1924 - 4pOhwM; two 350hp "Model W" engines; span: 115'0" length: 65'0" load: 12,250# v (est): 95/x/55. Airfoil-shaped fuselage. Not built.
WM 1922 = 1pOB; 400hp Liberty 12. Reported experiment with variable-camber wing using a De Havilland 4B. Uncertain if actually flown.
