Correct me if I am wrong, but these tanks does not look lthe same as the one used by Deuces. They look very similar in shape as the 450 gallon tanks used by the F-101s, only being smaller and 227 gallon. They are missing the fins on the Deuce tank and have a different pylon, but they have a small strake at the bottom center section like the 450 tanks have. The 450s did not have a pylon, but were attached directly to the F-101s belly. It looks like the Sixes 227 tanks had the pylon attached as integral part of the tank like the Deuce tanks. Looking at photos there are no RBF tags attached between the pylon and the tank, but only between the pylon and the wing.
There is a good photo of 59-0005 in the gallery showing the subsonic tank and its pylon.
Anyone having more info on the subsonic drop tanks?

The correct term is external tank.

The correct term is external tank. We did call them drop tanks, because they were jettisonable. The tanks on a T-33 and F-94 were called Tip Tanks...On some aircraft they were called pylon tanks and were not jettisonable.... So, the new comer used a nomenclature that an OLD FART understood

The correct term is external tank. "External tanks" has many names depending on service, a/c, nation or if they are jettisonable. The external drop tanks on F-16 are normally referred to as either centerline (for the belly mounted tank) or Dolly tank (for a wing mounted tank).
In US Navy, when pilots punched off to many "drop" tanks, the crewchiefs started calling them "keep" tanks to remind the pilots NOT to punch them off all the time.

Were you a USAF crew chief, or a USN plane captain? I am a long-time forum member/moderator, but have missed a bunch of stuff lately. Oh! I'm a retired USAF Master Sergeant. Started out as a KC-135 crew chief (E/R/T models) then became a C-130E/H/H1 Instructor Flight Engineer. Currently a T-1A Jayhawk crew chief. (Civil Service.) Been a long-time F-106 junkie here.

Mark O Info provided for your edification, you still have some live brain cells to be filled and I am trying to empty some of mine of 50-60 year old useless knowledge. Then some kid comes along and I find out the info is still there............

Well since I am just an old MA-1 Avionics guy, I know where to go to get the correct term. According to the 1F-106-1 Flight Manual they are called "External Wing Tanks". In the Pilots Checklist just External Tanks. The 1F-106A-2-2 Servicing Manual Calls them "External Tanks". 1F-106A-2-1 Aircraft General calls it the External Fuel Tank as does the 1F-106-4 IPB. So Mark even the Tech Manual System has a variation in how the tanks are named. The Old Sub-sonic (Cleared to mach 1.2) external tanks were called 230 gallon tanks, but Actually only 227 gallons. The supersonic 360 gallon tanks were cleared to Mach 2.0 and most missions they were used. But they were normally not used in Air To Air missions where G-Forces might exceed norm and FCF where speeds might go beyond Mach 2.0. Lorin

I remember the old subsonics from my early days but thought the supers were 375 gal. tanks but I could be wrong because I have made a mistake before I think.

If I had been USAF back in the Six days, I would have been a SAGE operator/controller. My best friend from my NATO assignment in Germany was a KC-135 navigator, but he is retired now. Just love the Six👍🏻 Ronny

Oswald Do you remember if the pylon was attached to the tank as an integeral part of the tank? According to T.O.s it is referred to as external tank/pylon assembly, and when released spring-loaded flaps close the openings in the wing. Photos do not show any anti-sway braces on the pylon either. The supersonic pylon and the Deuce pylon both have anti-sway braces. Ronny

Lorin,
That's actually really interesting! Up to this point, I didn't know of the mach limit.

Ronny The pylon was an integral part of the Drop Tank/External Tank, and as such, should the tank be jettisoned, the pylon went with it. Good to have an ACTIVE Duty Airman in here.. BTW, even the Dash One pilots handbook uses conflicting tank nomenclature. When I was at Loring (Oct 59 - Jan 64) The FCF (Functional Check Flight or commonly called Test Flight), regardless of reason was flown with droptanks/external tanks, whatever suits your fancy...The Old Sarge

Well, I guess the term "drop tank" will always be used. Must be a WWII thing that folks just can't let go of. FWIW, those external tanks are expensive, and although there may be rare times when a pilot has to let them go, it is pretty rare.
Oh well. Y'all call them what you want. I'm done.

Mark O Sorehead. spoilsport....... Those RF-101 450 gal jettisonable fuel tanks made good trading with the 7th Cavalry in VN...A pair of them got me a 3 1/2 hour flight in a Huey Gunship and 5,000 rounds of 7.62. Don't know if I hit much more than the ground. The grunts painted them black mounted them about 10 in the air and had solar heated water.......

Great info Jim!
Did the subsonic tanks have filler caps and where were they located on the tank?
See you have experience with the 450 gallon tank as well. Is it a corect statement that the Six subsonic tank externally looks like small version of the 450 (except the pylon)?
