In the lead up to the F-106 Reunion at Dayton, Bob Kwiecinski (or Bobski) was flooded with email traffic of all kinds. Among them were inquiries about many F-106 and Squadron topics. I tried to post them on the F-106 Forum and Bobski was forwarding many of them to the Reunion distribution list to get answers. Between Bobski and I we got a lot of answers to questions but some took awhile. I have over 1800 emails in my 2013 F-106 Archive Folder and Bobski probably has many more than that. One in particular on the F-106 M-61 20mm Gatling Gun created a lot of chatter. MOW's page www.f-106deltadart.com/weapons_20mm_cannon.htm has a lot of info on this topic but a few loose ends needed to be answered. So I went back through the emails and put them together in date order and I was going to put them in a post. But at 2700 words, I decided it would be better to post a PDF attachment than take up too much Forum real estate. So now, if you are a F-106 Gun Guy, you can open the attachment and read some good stories from our F-106 Flyers and Fixers. This is another example of how F-106 troops will use their network contacts to answer questions. Now, if we could just find a copy of the T.O. on F-106 Stencils and Markings to add to our Forum, I'd think Christmas came early. Pat P. F-106 Gun.pdf (26.47 KB)

I'm kinda baffled as to why these types of discussions, research, info etc don't happen here in the forums somewhere. Everything is all through email, which leaves a lot of possibilities out of the equations until someone like yourself compiles data. It would be nice to actually see some F-106 talk in here once in awhile rather than politics and this topic is a good one.

My stories are posted either here or in the old,old forum. Also, unlike the vast majority of the troops here, my 4 years of SIX time began with a/c so new that their flying time was from Palmdale to Loring, and we received them in serial number order. This apparently was before things got exciting with the aircraft. The reunion apparently produced many war stories of the plane and its people, hopefully they have been recorded to where they can be reproduced or published........Perhaps I might go back and bring some stories forward........

I like the idea of bumping up some old stories using the quote feature and asking a new question on the thread. This might generate some more discussion for the old threads they are in and offer an easy path to go back and read the entire thread if a new member has never been there before. Some of the best stories show up in the Old Sarge's story contest threads and the There I Was thread. The Reunion got us some new members signing on and making posts and we haven't been as "crisp" as we once were about welcoming them to the hangar and getting them to talk about themselves. The birthdays are on the home page and due to time constraints, my first stop is always on the Recent Posts page, so I don't send out as many birthday wishes as I used to. Today's Stats: Users Online in the Last 24 Hours 8 Staff, 9 Members, 277 Guests.Some of these 277 guests who don't log in can only see the non-Purgatory Recent Posts. I think I'll log off and see how many pages of Recent Posts show up compared to how many pages are shown when you are logged in. It may be that when we exclude Purgatory posts, there ain't much new in the way of airplane posts showing up on a daily basis. On the rare occasion I visit the site from another computer and don't log in my first thought is "wow, everyone must be on vacation". Then I log in and see a lot more posts from our usual members. Excuse me, I had to go fix a Jack Daniels and Hot Chocolate to fight off the cold weather. Boy Howdy, that's good! Due to my volunteer jobs I spend from 6-12 hours a day on the PC. I used to listen to Fox News in the background or talk radio. I stopped doing that about two years ago because that and the 50-100 emails I get every day were getting irritating with what we call Political Bull Manure. I don't mind reading it on our site and I even throw a "log on the fire" on occasion. But I think new members may be looking for more airplane content discussion since that is our primary mission. More of Today's Stats: Threads and Posts Total Threads: 4,402 Total Posts: 43,374 Total Categories: 5 Total Boards: 28We have a ton of airplane content buried in 43,374 posts. At an average of 2 minutes read time each it would take 1446 hours to read them all, or 60 days non-stop 24/7. Some of them take a lot longer than 2 minutes to read! So I guess it's up to us to dredge up some of the best stories and play them again to help new members find a way to contribute their content to the collection both on the Forum and the F-106 Main site. Mark Williams has been helping MOW spiff up the picture albums. MOW has been doing a bunch of behind the scenes work to make the main site better. One of the pages he is working on is Photo & Video > Audio and Video Library www.f-106deltadart.com/videoclips.htm . There's so much stuff there it takes the page a minute to paint it all. The latest add was a bunch of audio files I was able to capture at the F-106 Reunion in Dayton. I stole the idea from the audio/video military histories you see on the Military Channel. At the 2015 Reunion in Colorado Springs I hope we can set up a camera to record these "War Stories" from our F-106 Flyers & Fixers. Well, it's time to go watch The Five on Fox News and see what Kimberly Guilfoyle is talking about today. Pat P.

Like Jim, my 5 years on the Six were before a lot of the mods many of our members worked on and with.
No gun in my years, Jan 1962 - Feb 1967.
And, the canopy on the A Model had a beam on the top, front to back.
I did, however, see the addition of a shield around the Tail Hook Shoe.
That wasn't a bad idea, but it was more dangerous than the Shoe, as it was pointed to make it aerodynamic and put a lot of dents in heads, backs and shoulders.
I also saw the first IR heads installed, along with the LNG system, with a bottle and fill valve.
The biggest change I saw was the change from the Rocket Sled Seat to the Martin Baker seat.
That was a mammoth improvement for saving pilots lives.
There were tons of other changes in those years, and nearly every time a bird came in for Inspection, there was some minor mod to be done.
When I got on the Six, it had been flying for a while.
But, we did the first Periodic Inspections that required real tear down of some items, like removing the gear, pulling all interior panels, and lots of other things.
The MA-1 Weenies had lots of mods on their equipment, and systems that were feeding in to or from the MA-1 system.
Those years also saw the end of SAGE, no tears shed over that.
The SAGE Building at Minot was given to SAC and they used it for wing support offices and storage of lots of things.
ADC moved the Six FTD classes to the SAGE Building.
Oh, yes, the name was changed from SAGE Building to PRIDE Building.
I don't remember what PRIDE meant, it was some SAC thing, that those of us in ADC didn't pay any attention to.
Fun days as lots of us learned to work the Six, after having worked on earlier Interceptors and other birds.

Back in early 60's PRIDE was Professional Results in Daily Endeavors. The six's at McGuire had been there a few years when I arrived from MA-1 School in early 1964. They had the early IR heads and needed serviced with Nitro before each flight. Then later on we got the new IR system with self contained pump to recycle nitrogen. That was a big improvement. Most of our early system faults were the result of Crew Chief not properly servicing the system. If they ran pressure too high the lines would freeze over before tank was full and fluid would not last for full mission. After I went to Tyndall, we had several major mods to MA-1 and Airframe. Most were positive improvements for MA-1. But the biggest improvement was after I cross trained out of MA-1 into Flight Simulation. The replacement of the generators and Power Supplies. Stable power allied MA-1 to run much smoother. Lorin

Lorin - you would have been amazed at just how well the MA-1 performed at the end of the program! First - the IR was all revamped for the 3rd time when we installed TEC - Thermo Electric Cooldown. that eliminated the compressor, the nitro lines, the evaporators, the dehydrators and we never ever serviced any nitrogen again! Then we had AHRG. This eliminated the stable table and most all of the SCRG units. One main gyro with a lot of computer help. You could almost do a "waypoint" navigation to anywhere you wanted to go! Optical sight was pretty much gone and the HUD was installed on all the "A" models fitted with the gun. The Single generator feature was fantastic with the addition of PUP - the Power Upgrade. No longer needed the big ECU-10 or M-32 for ground power. All that was needed on ground was basically a 28VDC power. All power was derived from internal circuitry. We had a "589" unit in the 05 hole and a 926 unit in the RADAR rack to provide all power to our system. ALL those nasty old vacuum tube filters and voltage regulators were gone! MGUAMPS were never seen again! The AFCS was a great addition back in 1972-73. The old AFCS units in the 05 hole were removed and I personally kicked one across the hangar floor at speedliine at Hamilton! The bubble canopy and gun mod was added and when we picked up the HUD - Heads up Display- along with a totally new 149 unit the package really nested very well with our system. The only real hindrance was that only "A" model - Vertical taped birds would be used for the gun. NO "B" model was ever modded. The gun was in a pod mount and totally replaced the MB-1 rack in the weapons bay. Check with Ralph Robledo at Castle Air museum for close up pictures. He has the only gun pod - with gun - that I know of! UHF was modded and improved at least 3 times. The last radio I saw was an ARC-169. The TACAN was pretty much left alone though internal upgrades were accomplished. I'm sure there are a few other mods I missed - like the "Gold Plate" project that replaced ALL the coax connectors in the aircraft and the box and rack plugs with gold plated pins and connectors. That really made the system click! For the airframe - one big mod I do remember was a re-skinning of the aircraft wings. The upper skins were cracking at the rivit seams and the repairs were beginning to leak more than ever. The A.F. decided to re-skin the wings - thus giving many more flying hours to the airframes. In the end - the program was winding down so the numbers of airframes being modded were also reduced. The final tally on reskinning and gun mods along with the new RADAR receiver were reduced to about 85 total airframes. Oh - the new RADAR receiver was an all solid state model taken from the F-18! The paramp was replaced with a solid state device and really improved the reception and lockon range. Though the lockon - max range was left the same. I was there for some of the receiver testing on the HUGHE"S -WOOD NOSE" test mockup! YES - the frame of that mockup was actually made of wood - PLYWOOD to be exact! I had heard of it all my early career and finally got to see- and touch it! There was a whole new RADAR set with and new computer in the works for our MA-1. The computer would have mounted in the computer compartment along with a whole new rack. The new RADAR would have consisted of 4 units. The TX - The recr - and the video procesor AND a new antenna. Also - there would have been a whole lot of lead ballast added to balance out the airframe. So - you can see some of what you missed! If you have any questions - send me a message and I'll do my best to fill you in! MArv

Marv, Thanks for the rundown. The main reason I left MA-1 and cross-trained into Flight Simulation was the long hours of work. Our weekend "standby" duty was simply a 12 hour shift for two days followed by little, if any, comp time. Rotation varied, but averaged once every 3 weeks. McGuire was a little better than Tyndall. Tyndall had a larger number of birds and about the same number of folks working MA-1. Then add the transient birds and TDY units getting priority on mock-up. We usually did a quick swap for boxes from our flight line forward supply point. They only opened up the cross training for a few weeks and then stopped it. Seems too many wanted to do the same thing as I did. My class at Chanute had 3 MA-1 troops, and 4-5 MG10/MG13 troops. Half of us were from Tyndall. TSgt Vandenboom was one of MA-1 guys in class. He was a great guy. We all did a bunch of by-pass testing on things like basic electronics, digital fundamentals, and paperwork so we didn't spend the full time at Chanute.. But Flight Simulation was a great job. All inside and A/C work place. Little if any overtime (Exercises mainly) and liberal comp-time. I ended up spending 3 years at Chanute as they red-lined my Myrtle Beach A7 assignment and kept me as Instructor. But after that I had great assignments...6 years on F-111E at Upper Heyford UK, 2 years at Spangdahlem on F-4 Sim. Then 3 years at McChord on C-130/C-141. Then a by name assignment to WPAFB to finish my career. I was born in Columbus OH and raised in farm community near London OH. That was about 45 minute drive from WPAFB. So I home based my last assignment. MA-1 was much more of a technical, and wide range of systems to care and feed. Simulators were either Analog, a munch of servos with resistor wave shaping circuits and Instruments, or a Digital Simulation with fairly modern main-frame (or integrated mini-computers, visual systems and massive In/Out devices. I learned a ton about digital computers and peripherals in Flight Sim. So I made a great decision to cross train and it really helped in retirement. Lorin

Marv, That was the most clear and concise description of the evolution on the MA-1 system I have ever seen. It's absolutely amazing how technology drove the improvements in reliability and maintenance of that system and also influenced later improvements that resulted in the systems on the F-35 and F-22 fighters. GREAT JOB! Pat P.

Thanks for the pat on my back - Pat! I have more info but for now - I'll keep it aside until someone asks for it! I do have a short story about one of the mods - the TEC cooling for the IR head. When I was finally given the chance to go to my tech school for the MA-1 system - at Lowry, I had been in the Electronic Fundamentals school for a few years. Then when I came back to teach in the tech school I found myself as the resident expert on things like - "How does a vacuum tube amplifer actually work! - or Just how does that solid state tube relate to the old vacuum tube - or better - because the new power mods had just come in - How does a full wave rectifer work? I found that the students were asking these questions and the instructors did not have any answer for them - other than "Well - it just does" So I took it upon myself to get back into my system and look at those things we should have learned back many years before but had mostly forgot! Back to the IR story! One of the questions of the students was "What is the Peltier effect" because the TO, the -5 had that statement in the description. I took some time to research and find what it was and how the "Peltier Effect" actually occurred. Later when I went to the HUGHES site for the Solid State Receiver - I had the opportunity to ask the primary design engineers about it. Well - the same shrug I got from other Instructors was given me from the engineers. One actually had a very -VERY - basic idea. I took the moment to sit down - drew a picture or two and explained the whole thing to him and the second engineer with him. From that moment I could do no wrong! From that moment I was asked to participate in the actual testing of the new receiver and was shown and access several other projects that were in the works! End result - I was able to extend my TDY to HUGHES by 3 more weeks and participated in several more workshops and TDY's for the system. Loved it! MArv

I just had to look up the Peltier Effect as I recall hearing it from Physics class. Your story also reminded me of an old saying from a well know leadership author, John C. Maxwell: “People don't care how much you know until they know how much you care”. The Hughes engineers were inspired by both. Pat P.

I just read the pdf about the 20mm gun system. It brought to mind a mention that Bob Archibald (mentioned in the articles as heading the six shooter program) passed away a few months ago. He was quite a man, I only talked to him a view times but very briefly. A missed opportunity. He never stated that he headed up the six-shooter program. He owned Dragonfly Aviation that was adjacent to the Museum.

From: pgrignot@gmail.com To: Bobski9933@aol.com Sent: 4/28/2015 6:24:51 P.M. Eastern Daylight Time Subj: Re: F-106 -1 Manuals I was the lead IP in the F-106 Gun check out at Tyndall at IWS. Each squadron sent two IP's down and we taught them the Gunsight and the Gun and then qualified them for the gun on the Low Cost Tow Target (LCTT) towed behind an F-101. To my recollection the Sight could be put in any 106 but the gun could not be put in the "B". the Coffin Bay (radar/instrument/com-nav) in the back of the armament bay was not compatible with the MA61A gun itself. The Armament doors were different as well to allow for air scoops etc. Great Mod and a great sight. Better if we would have added the auto-lock-on range gate tested at Tyndall's 475th Test Sq. I had the opportunity fire with Auto-lock mod several times and it made life so much easier and better accuracy.. A radar lock made the small piper a Death cross. Two piper's with a Lock on and three pipers without. Looked like a wet noodle in flight without a Lock on but with just a little practice you could be deadly even without a lock on.... I have even more up to date Dash-1's but they have been added to for the Drone program. QF-106. Good news is, i believe we supplemented with another Book and did not alter the original Basic Dash-1. I will check and see but i believe i might have a pretty new Basic. I am reluctant to part with it but might be able to copy some pages on the Bore sight procedure etc. The pilot's manual had little change for the gun except to add the Gun to the Hydraulic schematic and the Electrical schematic as well. Secondary Hydraulics powered the main part of the gun and of course electrics to the Sight and trigger/arming set up.. I will look; as I am not sure if the Basic we used in the Drone program had the gun info; we did get a few 106 Drone modified A/C in with the sight still in it. Of course we took them out as well as the radar which improved visibility greatly.
We used a Maintenance manual for classroom training for the installation and mod set up and of course and hands on / eyes on visit to the plane..
I hope this helped some; you might be able to get hold of the maintenance manuals somewhere. Hope so... Blessings.

How often was the gun actually flown? I've seen lots of pictures of F-106s, but the only ones with the gun mounted were the test aircraft.

pat perry,
I never knew they had to modify the bay-doors to admit cooling-scoops for the gun.

I've at the site's page on the M61 cannon on the F-106A: It lists the following
1.) There was thought to using the aircraft for top-cover over Vietnam, and to this effect, the aircraft should be painted in camouflage, fitted with a clear-fit canopy and an M61 to allow close in kills at bombers, particularly at low altitude. 2.) In 1968, recommendations were made to expedite fitting the M61 to the F-106 as well as a clear-canopy, RHAW & ECM
I'm guessing the proposal for using the aircraft for top-cover over Vietnam was around 1964-1965 since that's when the air-war started, and the proposals for all the rest came around the same time to a year or so after: Am I wrong?

Well, zipper, seeing as how you are going back into time here in the forum, some place in here is a lengthy dissertation about the Gattling Gun and the 106, wrote by a pilot that flew with the gun. But really, why such strong curiosity? When you were born, politics had decided that the SIXES' days, along with that of the Air Defense Command were numbered. Anything said now would be pure conjecture and without proof, is useless conversation. Several of us have made remarks about previous members and their posts. If you are trying to impress us with your research talents, you are failing, and your style of writing is awfully similar to this guys..F-12B 6 Jan 2010 at 12:01am
I've heard a lot of things about the proposed F-12B which was to have been what the YF-12A would have been called had it entered production.
The plane would have had a partial chine at minimum and properly profiled IRST's.
However it would seem that all the other stuff about the plane is kind of confusing. Some sources say the plane would have had a flat antenna allowing it to fit within the confines of the SR-71's nose, and there are drawings which show a plane with an SR-71-esque chine. I've heard claims that it had the same fuel capacity as the larger SR-71. I'm not sure if it had a bob-tail or not.
I'm wondering if there's some confusion here. Keep in mind the following 1.) In the 1980's there was an SR-71-I proposal which was a modified SR-71 designed as an interceptor which did use a flat antenna and fit within the confines of an SR-71 nose 2.) The YF-12C was actually an SR-71A in disguise and all this stuff about the plane looking just like an SR-71 could have been misinformation to explain it away
Assuming it's not classified, can anybody shed some light on this?

1.) Does anybody have any picture, drawing, diagram, of what the slot looked like? (Assuming it's not classified)
2.) If the slot is opened at all speeds, how come it doesn't cause problems at transonic speed?
Is there any similarity to these 2 styles of posting? Who is it Mark?

Jim,
1. Just because something's old doesn't make it uninteresting: I suppose on some level I'm an aviation enthusiast, on another level, a bit of an amateur historian (I don't get paid to do it), and among areas of interest for me would include a. The transition from low-speed flight to high subsonic/transonic flight, and from there to supersonic flight b. The development of piston engines to gas-turbine engines c. The post-war switch from guns & cannon, to rockets & missiles (often involving the elimination of guns in aircraft such as the F-89, F-94C, and the F-86D which was gunless; the F-102 & F-106, and the F-4 Phantom), and the later decision to fit guns back into aircraft during the Vietnam/Post-Vietnam-era.
2. I wasn't trying to impress anybody with my research talents: I'm mostly trying to learn more about the F-106, and other aircraft. I would, of course, be happy if some of the knowledge I learned, reasonably speaking, would somehow help the site.
3. As for the writings: They would look like my writing style because they were my writings: I used the screen-name delta2477a. I forgot the password to the forum account, I don't remember the password to the e-mail account (I haven't used it in years), and if I recall right, it's inactive. When I created my account, I made this known.
