The '''Republic F-105 Thunderchief''' is an American [[fighter-bomber]] that served with the [[United States Air Force]] from 1958 to 1984. Capable of Mach 2, it conducted the majority of strike bombing missions during the early years of the [[Vietnam War]]; it wasis the only American aircraft to have been removed from combat due to high loss rates.<ref>Davies 2010, p. 6.</ref> It was originally designed as a single-seat, nuclear-[[attack aircraft]]; a two-seat [[Wild Weasel]] version was later developed for the specialized [[Suppression of Enemy Air Defenses]] (SEAD) role against surface-to-air missile sites. The F-105 was commonly known as the "Thud" by its crews.
 
As a follow-on to the Mach 1 capable [[North American F-100 Super Sabre]], the F-105 was also armed with missiles and a rotary cannon; however, its design was tailored to high-speed low-altitude penetration carrying a single [[nuclear weapon]] internally. First flown in 1955, the Thunderchief entered service in 1958. The single-engine F-105 could deliver a bomb load greater than some American [[heavy bomber]]s of [[World War II]] such as the [[Boeing B-17 Flying Fortress]] and [[Consolidated B-24 Liberator]]. The F-105 was one of the primary attack aircraft of the [[Vietnam War]]; over 20,000 Thunderchief sorties were flown, with 382 aircraft lost including 62 operational (non-combat) losses (out of the 833 produced). Although less agile than smaller MiG fighters, USAF F-105s were credited with 27.5 kills.

During March 1956, the USAF placed a further order for 65 F-105Bs and 17 RF-105Bs.<ref name=Knaack_p192>Knaack 1978, p. 192.</ref> In order to conduct the nuclear mission, an MA-8 [[fire control system]], [[List of radars#AN/APG Series|AN/APG-31]] ranging [[radar]], and K-19 gunsight to allow for [[toss bombing]] were integrated.<ref>Anderton 1983, p. 25.</ref> On 26 May 1956, the first pre-production YF-105B made its maiden flight.<ref name=Knaack_p192/> Five of the F-105C trainer variant were added to the procurement plan in June 1956, before being canceled during 1957. The RF-105 reconnaissance variant was canceled in July 1956.<ref name=Richardson_p12-3/> The first production F-105B was accepted by the USAF on 27 May 1957.<ref name=Knaack_p193>Knaack 1978, p. 193.</ref> In June 1957, Republic Aviation requested that the F-105 be named ''Thunderchief'', continuing the sequence of the company's Thunder-named aircraft: [[Republic P-47 Thunderbolt|P-47 Thunderbolt]], [[Republic F-84 Thunderjet|F-84 Thunderjet]], and [[Republic F-84F Thunderstreak|F-84F Thunderstreak]]. The USAF made this name official one month later.<ref name=Richardson_p12-3>Richardson 1992, pp. 12–13.</ref>
 
===Later development===
To fulfill the USAF's requirement for an all-weather attack aircraft, Republic proposed the F-105D variant during 1957.<ref name=Knaack_p193/> This version featured an enlarged nose and radome housing the AN/ASG-19 ''Thunderstick'' bombing/navigation system. The AN/ASG-19 was designed around the [[Autonetics]] R-14A radar, which operated in both air-to-air and air-to-ground modes, and the AN/APN-131 Doppler navigation radar. In the cockpit, the F-105D featured vertical-tape instrument displays for adverse weather operation. The ability to carry the [[B43 nuclear bomb|TX-43 nuclear weapon]] was also added. On account of these myriad changes, Republic noted the difficulty of using the same production line as had been used for the F-102B105B; production times would also be extended from 144 days to 214 days.<ref name=Knaack_p196>Knaack 1978, p. 196.</ref>
 
Development of the RF-105 reconnaissance model was restarted during the late 1950s, for a time based on the F-105D, before work on the model was cancelled for the final time on 23 December 1960.<ref name=Knaack_p199/> On 18 March 1959, the planned F-105E twin-seater was also cancelled due to its high cost; it was replaced on a one-to-one basis by additional F-105Ds.<ref name=Knaack_p196/> On 9 June 1959, the first F-105D took its maiden flight.<ref name=Richardson_p12-5>Richardson 1992, pp. 12–13, 15.</ref> Flight testing of the F-105D was somewhat less troubled than the less advanced F-105B, to the point where the D-model was ready for operational service ahead of its predecessor.<ref name=Knaack_p196-197>Knaack 1978, pp. 196-197.</ref> Category II flight testing in late 1959 identified various key deficiencies on the F-105B, particularly with the MA-8 fire control system and autopilot of this variant.<ref name=Knaack_p194/> While eventually rectified successfully, it took time to develop and deploy appropriate modifications, putting the production programme further behind. By the start of 1960, none of the 56 F-105Bs that had been delivered were considered to be operationally ready.<ref name=Knaack_p194/>
 
[[File:F-105 Thunderchiefs Mt Fuji.jpg|thumb|A USAF F-105F trainer and a F-105D with [[Mount Fuji]] in the background]]
At one point, there were plans in progress to procure in excess of 1,500 F-105Ds; however, production schedules continued to be missed, in part due to [[industrial action|strikes]] by Republic's workforce, that impacted the USAF's plans for the type.<ref name=Knaack_p198>Knaack 1978, p. 198.</ref> Production of the F-105 was heavily impacted by the decision taken by Secretary of Defense [[Robert McNamara]] to equip no more than seven combat wings with the type. During November 1961, production of the type was cut in favor of the USAF adopting the Navy's F-4 Phantom II,<ref name="IAPR6 p130">Davis 2002, p. 130.</ref> and in the longer term, the [[General Dynamics F-111 Aardvark]] of the TFX program.<ref>Anderton 1983, pp. 62-63.</ref> While considerations towards reopening production of the F-105 were discussed in 1967, this interest did not ultimately see any such revival.<ref name=Knaack_p200>Knaack 1978, p. 200.</ref>
 
The final 143 Thunderchiefs built were of the two-seat F-105F trainer variant.<ref name=Knaack_p201>Knaack 1978, p. 201.</ref> Based on the F-105D, this model was 31&nbsp;inches (79&nbsp;cm) longer to provide room for the rear cockpit; otherwise, the aircraft had similar flight performance to the preceding F-105D.<ref name=Richardson_p20>Richardson 1992, p. 20.</ref><ref>Anderton 1983, p. 75.</ref> A total of 833 F-105s were completed before production ended in 1964.<ref name="Angel p410">Angelucci 1987, p. 410.</ref> The F-105 had been designed for a short nuclear campaign, leading to shortcomings that became evident in a lengthy conventional war, such as a poor [[hydraulic]]s layout and fuel tanks that were not [[Self-sealing fuel tank|self-sealing]].<ref>{{cite magazine |last=Werrell, |first=Kenneth p.|title=Did [USAF Technology Fail in Vietnam? |url=http://www.airpower.maxwell.af.mil/airchronicles/apj/apj98/spr98/werrell.pdf "Did USAF Technology Fail in|url-status=dead Vietnam?"] {{Webarchive|archive-url=https://web.archive.org/web/20161230073700/http://www.airpower.maxwell.af.mil/airchronicles/apj/apj98/spr98/werrell.pdf |archive-date=30 December 2016 }} ''|magazine=Airpower Journal'', |date=Spring 1998. |pages=87–99}}</ref> Subsequent upgrades improved the reliability and weapons capacity of the existing F-105Ds. In response to the [[surface-to-air missile]] (SAM) threat experienced in the skies above Vietnam, dozens of F-105Fs were converted into anti-radar "[[Wild Weasel]]" aircraft, culminating with the F-105G.<ref name=Richardson_p28_38>Richardson 1992, pp. 28, 32–33, 38.</ref><ref>Anderton 1983, pp. 125-126.</ref><ref name=Knaack_p203>Knaack 1978, p. 203.</ref>

The F-105 was a mid-wing monoplane with a 45° [[swept wing]] and tail surfaces. The single engine was fed by two intakes in the wing roots, leaving the nose free for a [[radome]] housing the multi-mode [[radar]].<ref name="JAWA66 p243-4">Taylor 1966, pp. 243–244.</ref> Its fuselage provided room for {{convert|1184|gal|L|lk=on|sigfig=3}} of fuel and an internal bomb bay. The bomb bay measured {{convert|15|ft|10|in|m|sigfig=3}} by {{convert|32|in|m|abbr=on|sigfig=2}} by {{convert|32|in|m|abbr=on|sigfig=2}}; it was originally designed to carry a single [[nuclear weapon]] but typically held an additional {{convert|350|gal|L|abbr=on|sigfig=2}} fuel tank.<ref>''Republic F-105 Thunderchief Pilot's Flight Operating Instructions'' 2008, p. 16.</ref> It featured four under-wing and one centerline pylon; the two inner wing and centerline pylons were capable of accepting fuel from {{convert|450|and|650|gal|L|abbr=on|sigfig=2}} [[drop tank]]s. Two outer dry stations were wired for missiles or bombs.<ref name="Tech p47">Davis and Menard 1998, p. 47.</ref><ref name="IAPR6 p141">Davis 2002, p. 141.</ref> One [[M61 Vulcan]] (initially designated ''T-171E3'') [[20 mm caliber|20 mm]] 6-barrel [[Rotary cannon|Gatling-style cannon]] was installed in the left side of the nose. A short-range [[AIM-9 Sidewinder]] air-to-air missile could be carried on each of the outer wing pylons.<ref name=Richardson_p22-4>Richardson 1992, pp. 22–24.</ref>
 
The F-105 was designed primarily for low-level interdiction and its low-altitude speed was its greatest asset when dealing with enemy fighters such as the [[Mikoyan-Gurevich MiG-17|MiG-17]]/[[Shenyang J-5|J-5]]s<ref>Toperczer 2001, pp. 65–74.</ref> and [[Mikoyan-Gurevich MiG-21|MiG-21]]. The F-105 managed 27.5 air-to-air victories.<ref name="Futrell p157">Futrell et al. 1976, p. 157.</ref> Based on combat experience, the F-105D was updated with a better [[ejection seat]], additional armor, improved gun sights, and [[Electronic countermeasure|Electronic Counter Measures]] (ECM) pods on the wings.<ref name=Knaack_p199>Knaack 1978, p. 199.</ref>
Line 72 ⟶ 78:
The initial reaction of the fighter pilot community to their new aircraft was lukewarm. Between its massive dimensions and troubled early service life, the F-105 had garnered a number of uncomplimentary nicknames. In addition to the aforementioned "Thud", nicknames included the "Squat Bomber", "Lead Sled", and the "Hyper Hog" and/or "Ultra Hog".<ref>Anderton 1983, p. 11.</ref> The latter two names arose from the F-105's predecessors, the Republic F-84 Thunderjet and F-84F Thunderstreak, nicknamed "Hog" and "Super Hog", respectively. According to F-105 pilots and crews, the "Thud" nickname was inspired by the character "Chief Thunderthud" from the ''[[Howdy Doody]]'' television series.<ref>{{cite web |last1=Laurence |first1=Mike |title=The Thud |url=http://faculty.buffalostate.edu/fishlm/folksongs/thud.htm |date=7 January 1994 |access-date=18 April 2015 |archive-date=3 March 2016 |archive-url=https://web.archive.org/web/20160303215417/http://faculty.buffalostate.edu/fishlm/folksongs/thud.htm |url-status=live }}</ref>
 
The aircraft's offensive capabilities were sarcastically referred to as a "Triple Threat"—it could bomb you, strafe you, or fall on you.<ref>Hannah,&nbsp;C.&nbsp;C. (2002). ''Striving for Air Superiority: The Tactical Air Command in Vietnam''. United States:&nbsp;Texas A&M University Press. p. 49.</ref> Positive aspects, such as the F-105's responsive controls, strong performance at high speed and low altitude, and its outfit of electronics won over some pilots. For some, "Thud" was a term of endearment; retroactively the [[Republic F-84F Thunderstreak|RF-84F Thunderflash]] became known as "Thud's Mother".<ref name=Higham>Higham and Williams 1975, pp. 185–190.</ref> F-105 pilot Colonel [[Jacksel M. Broughton|Jack Broughton]] said of the nickname: "The Thud has justified herself, and the name that was originally spoken with a sneer has become one of utmost respect through the air fraternity".{{sfnp|<ref>Broughton| 2006|pages=, pp. 38–39}}.</ref>

In 1965, the USAF began operating two-seat [[North American F-100 Super Sabre|North American F-100F Super Sabre]]s specially equipped for [[Suppression of Enemy Air Defenses]] (SEAD) missions in Vietnam. Nicknamed the Wild Weasel, these aircraft achieved a number of victories against North Vietnamese surface-to-air missile radars. The second crew member was a [[Combat Systems Officer|Navigator]] trained as an Electronic Warfare Officer (EWO) to decipher sensor information and guide the pilot towards the targets.<ref name="Dorr de p60-1">Dorr and Bishop 1996, pp. 60–61.</ref> However, the F-100F was an interim solution, since its limited payload often required multiple aircraft to conduct a successful strike; it also lacked the speed and endurance to effectively protect the F-105.<ref name="Lake p31">Lake 2004, p. 31.</ref><ref name="IAPR6 p135">Davis 2002, p. 135.</ref>

The resulting EF-105F Wild Weasel III{{#tag:ref|The Wild Weasel IA and II designations referred to experimental conversions of F-105Ds and F-105Fs respectively which were used to evaluate various sensor and [[Electronic countermeasure]] (ECM) equipment.
