Made by Republic Aviation around 1960, this F-105 Thunderchief promotional film - originally classified "Secret" according to a card at the end - focuses on the aircraft's armament capability and spin tests. The film begins with astonishing shots of the aircraft's wide array of ordnance, and shows the supersonic aircraft's large bomb bay, equipped with an ejection system. The bay can also carry an extra fuel tank or small training bombs.
The aircraft is shown performing supersonic maneuvers at the 4:00 mark, with precision bomb release, including 1000 lb bombs. Sidewinder capable racks are shown installed at the 4:50 mark. A sidewinder vs. HVAC rocket is seen at the 5:40 mark. The F-105's 20mm Vulcan gun is seen at the 5:50 mark.
Spin maneuvers are seen at the 7:30 mark, the location of many of the tests appears to be Edwards Air Force Base.
The Republic F-105 Thunderchief was a supersonic fighter-bomber used by the United States Air Force. The Mach 2 capable F-105 conducted the majority of strike bombing missions during the early years of the Vietnam War; it was the only U.S. aircraft to have been removed from combat due to high loss rates. 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 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 F-105 could deliver a greater bomb load than some American heavy bombers 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.
The Thunderchief was the largest single-seat, single-engine combat aircraft in history, weighing approximately 50,000 pounds (23,000 kg). It could exceed the speed of sound at sea level and reach Mach 2 at high altitude; the F-105 could carry up to 14,000 lb (6,400 kg) of bombs and missiles. The Thunderchief was later replaced as a strike aircraft over North Vietnam by both the McDonnell Douglas F-4 Phantom II and the swing-wing General Dynamics F-111 Aardvark. However, the "Wild Weasel" variants of the F-105 remained in service until 1984 after being replaced by the specialized F-4G "Wild Weasel V".
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". The latter two names arose from the F-105's predecessors, the Republic P-47 Thunderbolt and F-84 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.
The aircraft's offensive capabilities were sarcastically referred to as a "Triple Threat" - it could bomb you, strafe you, or fall on you. 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 RF-84F Thunderflash became known as "Thud's Mother". F-105 pilot Colonel 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".

Damn, I hope some museum can restore 1 to flying condition, to show how badass we were 60 years ago. Amazing how easily it recovers from a spin, what a plane.
What an aircraft! Even today pretty much nothing faster at low level.
Awesome video, thanks for posting! I can say with 99.99% certainty that from the beginning of this video to 7:36 was filmed at Eglin AFB in Florida.
Unusually good film quality.
5:36 That THAT was cool. I'd never heard of that type of test.
@Ronald Blythe Not as waistfull as destroying converted QF4 or QF16.
I wonder if Mercury astronaut Deke Slayton is at the controls during the spin test. To quote Wikipedia..."was responsible for determining stall-spin characteristics for the large F-105"
To quote the late, great Deke Slayton: "Up yours, Mr. Republic. Your 105's been spun, son."
Great with spin recovery - I think the boys that used it on the deck in Europe and Vietnam were very comforted by the thought, that if they ever got into a spin, they would recover within a minute of smashing into the ground.
I like the color schemes on the aircraft.
Sleek fast and kick ass need i say more.
Voluntarily testing an aircraft through 5 turn spins before even beginning recovery procedures? True Grit.
The F-105 Thunderchiefs was great airplanes, but had a weakness because they was not that good at defending themselves when going on bombing missions and the one airplane which made their job easier was the F-4 Phantom as they took on the defense of the F-105's as they went to their targets to bomb ground targets.
The F-105 pilots claimed 27.5 air-to-air victories for themselves in Vietnam, against 17 loses (USAF claims). They where not a sitting duck as people believe they were. The majority of their losses where from AAA. Keep in mind that, the ridiculous regulations and inflexible tactics on the theater mean that they flew towards a enemy that were waiting for them, guns pointed at the same direction over and over again.
The heavy losses cannot be replaced simply because the USAF was told to stop buying them (and the F-106) in favor of the F-4, as per McNamara orders, so that mean the F-4 was the only replacement available on Vietnam. Despite that, they continued to serve there until the end of aerial operations.
Yep and kind of hard to dog fight with tons of bombs hanging on your wings.
Thud was the sound of an f105 when it smashed into this ridge in nam
Это - "герой" Вьетнама? А у него есть радар?
3000 lbs of ordinance on inner wing and 1000 outer? does that sound correct? 3000 sounds high..
I think it had a larger bomb load than the B17. Bomb loads were as high as 14,000lbs!!!!!
@@indigohammer5732 Amazing. My uncle flew 100 missions in this plane in Vietnam, flying out of Thailand - he had some stories!
We need this aircraft in DCS.
This bomb bay mechanism seems unnecessarily complex. Was this really effective in combat?
It was all about nuke delivery. The century series planes were all about nuclear offense/defense. They weren’t meant to do the job they did in Vietnam. The F-101 and F-105 and the Navy A-5 all had internal nuke delivery. The F-102, F-104 and F-106 were all interceptors/point defense fighters meant to attack incoming soviet bombers. The F-100 was just a shitty overgrown Sabre.
"5 inch, high velocity, aircraft rocket"? Is this just a way of saying, "slightly slower Sidewinder"?
5" Zuni High Velocity Aircraft Rocket (HVAR). They have a variety of warheads including "proximity fuzed" which could be used against aircraft or ground targets and would detonate when it was close to the target. Unlike the Aim-9 Sidewinder the Zuni was unguided.
I hated anything to do with the Zuni's or the 2.75" rockets. Damn rocket pods were heavy and we handloaded the whole pod to the aircraft. They are very sensitive to stray voltage/static electricity so making the final electrical connections from pod to plane was a job everyone dreaded. This is what started the USS Forrestal fire.
The aircraft launched its own target, it looked like the aircraft had two Sidewinders. When the target missle launched it appeared to be one of these. It seemed to me the target (HVAR) itself was based on the Sidewinder, but I may not have been interpreting what I was seeing correctly. Thanks.
HVAR.
Spin recovery has been replaced by motion sickness medication.
This nickname, Thud, came from the sound it made when it touched down. Hence, lead sled.
The name has a darker origin unfortunately. Pilots called it the Thud because its the noise it makes when it impacts the ground. It got that name from its combat record over Vietnam. They couldn't fight other aircraft at all. So if they were caught alone without escort they were slaughtered. They're huge aircraft as well, so the SAMs locked on to them easily. 395 F-105s were lost over Southeast Asia. Absolutely horrifying.
@@terrancestorey7254 in large part the losses were due to the insane rules of engagement that had them fly near known SAM and AA sites without being allowed to destroy those threats.
Had they been allowed to take out those sites losses would have been far lower.
Stupid politicians...
Nick name Thud from cartoon character.
@@terrancestorey7254 F-105s were also unreliable early on, hence many "Thuds". When loaded down with fuel tanks and many drag inducing bombs they were not very fast and susceptible to slashing radar-guided Mig-17 and Mig-21 attacks. But if unloaded and on the deck nothing could catch them. They were not designed for use in SEA (nor was the F-100 or the F-104) and have whatever you have on hand. The belly compartment was converted to house additional fuel.
@Richard McCaig yes it is.
NASCAR/And car racing picked up on these spoiler Technologies
Fairchild?
+tamgila This film was shot in the late 1950's; it was still called Republic Aviation. Fairchild didn't take over until 1964.
Phayzyre105 Tanks
Republic.
They were built at the Republic Aviation plant in East Farmingdale Long Island, which was at the upper end of the Republic airport property. It was the last independent design of Republic Aviation before Fairchild took over. Their next most famous product the A-10 Thunderbolt II (Warthog) is still flying today and is supported by Northrup Grumman. There is a nice example of the F-105 at the American Airpower Museum, in a building that was part of the sprawling Republic complex. Sadly all of the other buildings are long gone, it is a shopping center now. There are some ruins on the north side of the LIRR tracks that I believe were part of Republic's operation many years ago.
