F-105

Dear Friends

Could anybody tell me the maximum low level level speed of a F-105?

Merry Christmas.

Cheers

Wiki has it as: Mach 1.1, 836 mph (1,345 km/h) at sea level; Mach 2.08, 1,372 mph (2,208 km/h) at 36,000 ft (11,000 m)

Wiki is quoting all official figures which is fine if that's what you want. The low-level speed is probably in clean condition at max power and could be sustained for about 35 sec before running out of gas. The high-altitude speed is also clean, and on a cold day to boot. I have heard it suggested that by the end of the Thud's career the aircraft were too knackered and modified to go supersonic at all.

KITBAG quickly had the answer -- but there must be some larger question you are pursuing ?

Are you particularly interested in the F-105 itself ... or in aircraft low level speeds, generally ??

Surely it depends whether horizontal or vertical prior to impact!

...there was an F-105 that crashed straight down in full afterburner, after complete instrument/electrical failure in IMC {..Vandenberg AFB California, 25+ years back}

More to the point - why were they called "Widow Makers" - could ask the GAF!
Low Observable - I think the "Thud" was a B57 employed in Vietnam

Ummm....no.

GAF flew F-104s. No other countries save the US flew the mighty 'Thud.' Although there was an interesting article recently by an RAF exchange officer who claims the last F-105D sortie years ago at Nellis.

B-57 was not the 'Thud.'

The F-105 Thunderchief was nicknamed the "Thud" due to the numbers of losses it suffered in the Vietnam War. The Thuds were the mainstay of the Air Force's effort and as a result had more exposure in combat than other types of aircraft.

There is nothing more impressive than a clean Thud in overdrive in the tree tops!

She is big...loud....and FAST!

Recently seen reports that the Collings Foundation are seriously putting together plans to return a 'Thud' to the air to fly alongside it's F-4 and A-4.....

A certain 'warbird enthusiast and current UK based Eagle driver was salivating at the prospects of volunteering to be checked out in it if it comes to fruition...

The F-105 Dash-1 (pilot manual) states that on a standard day, with 0 drag index (clean), and in full afterburner, the Thud could get to Mach 1.1.

Apocryphal story of a radio exchange between a lead and his wingman doing a Pack Six over the nasty bits of Viet Nam.

"Where are you 2?"

"Lead - 2 is at bullseye blah, range blah at blah. An' about a hundred feet!"

"Watchya' doin' down there?"

"A THOUSAND MILES AN HOUR - SOUTH!"

The Thud

A USAF Exchange Officer once described it to me as "The Triple Threat Bomber", Bomb 'em, Strafe 'em, Fall On 'em.

Beags, same story I guess, low level over Nam (did they use bullseye then?), but the version I heard was:

"2, where are you?"

"I don't know man, but I'm doin' a thousand miles an hour!"


No doubt some F3 mate wants to join in on this debate.... Only one thousand eh, then I selected burner on the other engine, blah blah

I never got one over 800kts, but that's when they were shiney and new....

Thud trivia:

610 F-105D's built (single seat)
143 F-105Fs built (two seats, most later converted to F-105G Wild Weasels)
334 combat losses in SEA.

Used by the USAF Thunderbirds for first half of 1964 season. One broke in half during a pull-up, rest of the season flown in F-100s.

Must be a candidate for largest/heaviest single-engined aircraft. Any thoughts?

Can't think of anythink heavier but there must have been bigger aircraft. Wasn't the Vigilante single engined for example?

Jack Broughton's book Thud Ridge describes flying the 105 beautifully. Nothing faster at low level, could haul an unbelievable load, no turn rate worth a damn, had a real Vulcan cannon up front, vulnerable hydraulic system and a seat which was likely to break your back if used in anger. Loved to have seen one in the flesh. What a great looking bird.

I don't own this space under my name. I should have leased it while I still could

The USAF did a trial, back in the early 60s, IIRC, to investigate the lethality of supersonic flight on ground troops. They determined that it was indeed possible to incapacitate, or even kill, ground troops through supersonic overflight.

There was a catch.

The Thud had to fly supersonic at 5 feet. It would probably have killed more enemy using the airbrake as an axe.
