[[File:F4B-4s VF-9M-VMF-111 NAN10-81.jpg|thumb|Formation of F4B-4 in the 1930s]]
The '''Boeing P-12''' or '''Boeing F4B''' is an [[United States of America|American]] [[fighter aircraft|pursuit aircraft]] that was operated by the [[United States Army Air Corps]], [[United States Marine Corps]], and [[United States Navy]]. It was the chief fighter aircraft in American service during the early 1930s but also used internationally. By the late 1930s it was replaced in front-line duty by newer designs, but it was still used for training into the early 1940s. Many variants of the aircraft were developed. In the 21st century a handful of surviving air frames are on display in museums.

==Design and development==
Developed as a private venture to replace the [[Boeing F2B]] and [[Boeing F3B|F3B]] with the [[United States Navy]], the Boeing Model 99 first flew on 25 June 1928. The new aircraft was smaller, lighter and more agile than the ones it replaced but still used the [[Pratt & Whitney Wasp|Wasp]] engine of the [[Boeing F3B|F3B]]. This resulted in a higher top speed and overall better performance. As result of Navy evaluation 27 were ordered as the '''F4B-1'''; later evaluation by the [[United States Army Air Corps]] resulted in orders with the designation '''P-12'''. Boeing supplied the USAAC with 366 P-12s between 1929 and 1932. Production of all variants totaled 586.

'''F4B-1 (Boeing Model 99)'''

The F4B-1 was built using typical construction techniques of the day with a [[Welding|welded]] [[truss]] [[fuselage]] with [[former]]s and [[longeron]]s to define the aerodynamic shape. Wings were of wood construction<ref>{{Cite web|title=Boeing F4B-4|url=https://airandspace.si.edu/collection-objects/boeing-f4b-4/nasm_A19610200000|access-date=2021-03-07|website=National Air and Space Museum|language=en}}</ref> and covered by fabric. [[Aileron]]s were tapered, with corrugated aluminum covering. The Pratt & Whitney R-1340 nine-cylinder [[radial engine]] was uncowled and sported prominent cooling [[Aircraft fairing|fairings]] behind each cylinder which were later removed in service.

'''F4B-2 (Boeing Model 223)'''

The F4B-2 was similar to the F4B-1 but incorporated a [[Townend ring]] cowling around the engine. The prominent cooling fairings behind each cylinder were not incorporated on this model. A spreader bar was incorporated between the landing wheels and the tail skid was replaced by a castoring tailwheel. Finally, the tapered ailerons were replaced by constant chord [[Frise aileron]]s. A total of 46 production F4B-2s were built. Bureau numbers included A-6813 through A8639 and A-8791 through A-8809. Some F4B-2s received F4B-4 style vertical fins and rudders to address poor directional stability.

'''F4B-3 (Boeing Model 235)'''

The F4B-3 represented a significant departure in design from the earlier versions of the F4B. While the F4B-1 and F4B-2 had fuselages constructed of welded steel tube truss, the F4B-3 used a combination of welded truss and [[semi-monocoque]] construction. From the engine mount aft to the rear of the fuel tank bay, the structure was welded steel truss, while the fuselage aft of the fuel tank bay was constructed of stressed skin, semi-monocoque aluminum alloy. Wings were constructed primarily of wood and covered in fabric. The F4B-3 was powered by a single-row, nine-cylinder Pratt & Whitney R-1340-D engine generating 500&nbsp;hp. It had an internal [[supercharger]] and turned a 9&nbsp;ft. two-blade Hamilton Standard propeller. The original configuration of the F4B-3 has a headrest fairing similar to the P-12E, but most were retrofitted with a headrest fairing capable of storing a liferaft. This later headrest fairing design was carried over to the F4B-4.

'''F4B-4 (Boeing Model 235)'''

The F4B-4 was nearly identical to the F4B-3, but incorporated a larger vertical fin to address the directional stability issues that plagued the F4B from its inception. The design was so similar to the F4B-3 that both aircraft had the same Boeing Model Number (235). The first nine aircraft (A-8912-8920) featured the same carburetor induction scheme as the F4B-3, but all following aircraft (A-8009-A-9053, 9226-9263 and 9719) featured a single oval carburetor intake on the port side only.

'''F4B-5 (Boeing Model 261)'''

A detailed specification was written for an F4B-5 as a minor development of the F4B-4 but was not proceeded with.

==Operational history==
[[File:17th Pursuit Squadron P-12s - March Field about 1932.png|thumb|Row of Army Air Corps P-12s in 1932, of the 17th Pursuit Squadron]]
'''U.S. Army Air Corps'''

P-12s were flown by the 17th Pursuit Group (34th, 73rd, and 95th Pursuit Squadrons) at [[March Air Force Base|March Field]], [[California]], and the 20th Pursuit Group (55th, 77th and 79th Pursuit Squadrons) at [[Barksdale Air Force Base|Barksdale Field]], [[Louisiana]]. Older P-12s were used by groups overseas: the 4th Composite Group (3rd Pursuit Squadron) in the [[Philippines]], the 16th Pursuit Group (24th, 29th, 74th, and 79th Pursuit Squadrons) in the [[Panama Canal Zone|Canal Zone]], and the 18th Pursuit Group (6th and 19th Pursuit Squadrons) in [[Hawaii]].

The P-12 remained in service with first-line pursuit groups until replaced by [[Boeing P-26 Peashooter|Boeing P-26]]s in 1934–1935. Survivors were relegated to training duties until 1941, when most were grounded and assigned to mechanic's schools. 23 P-12Cs, P-12Ds and P-12Es were transferred to the Navy for use as advanced trainers. Bureau numbers were 2489 through 2511. These aircraft were redesignated as F4B-4As.

'''U.S. Marine Corps'''

F4Bs were flown by two Marine squadrons. VF-10M flew F4B-4s from February to July 1933. In June 1933, the squadron mission changed from Fighting to Bombing and was redesignated as VB-4M. By direction of MAJ Roy S. Gieger, Officer-in-Charge of Marine Corps Aviation, all VF-10M F4B-4s on strength be transferred to VF-9M at Quantico. By September 1933, VB-4M had been re-equipped with 16 F4B-3s.

VF-9M based at Brown Field, Quantico flew F4B-4s, starting the transition in September 1932. In June 1933, VF-9M received all of the F4B-4s transferred from VF-10M. VF-9M flew their F4B-4s until 1938 when they were replaced by Grumman F3F-2s.

A single F4B-3 (BuNo) 8911 was assigned to Headquarters, U.S. Marine Corps and was the personal aircraft of Col. Ross “Rusty” Rowell, Director of Marine Corps Aviation.
