From an RF-4C stores limitation chart, the USAF used McAir and Royal Jet C/L tanks. McAir and Sargent-Fletcher made the wing tanks. The McAir C/L limits are somewhat higher than the Royal Jet's, but the jettison limits are the same. The Navy tank was stressed for close to aircraft limits and with lower drag than a pair of outboard 370s made for better efficiency all around. Drag appears to be the same as a pair of 370s. snip Normally each F-4 carried 2 Aim-7 missiles in the under fuselage cavities and four Aim-9H or G missiles on under wing pylons. Here you highlight one shortcoming of the C/L tank option. Two of the four missile wells couldn't be used. Considering the reliability of AIM-7s after a few cat shots and traps, I imagine it wasn't a big deal. And you could always punch the tank. By 1972 USAFf-4s were normally just carrying a pair of AIM-7s in the aft wells, with jamming or camera pods in the forward wells. and unlike the USAF, the navy had already modified their I/B pylons to carry AIM-9s and other ordnance simulataneously. Cunningham/Driscoll had been carrying Rockeyes on I/B TERs (plus a C/L, 2 AIM-7s and 4 x AIM-9Gs) when they claimed 3 MiGs with AIM-9s on 10 May. Air-to-ground ordnance was hung in TERs (triple ejector racks) under the wings. MERs (multiple ejector racks) could be carried but normally weren't. Are you saying it was Navy practice to carry TERs on the outboard stations rather than MERs? I've got more than a few shots of TERs O/B on navy F-4s in Vietnam, but I've also got a couple showing them carrying MERS (and bombs) there. Never saw it done in the USAF. Seems like it would create a very forward C/G. ISTR reading that one of the reasons the navy didn't like to carry wing tanks was apparently due to overrotation following the cat shot, probably owing to fuel slosh creating an aft Cg, so a more forward Cg would seem to be a good thing for their purposes. A M-60 gun pod (SU-23) was tested. This pod was about the size of a centerline fuel tank, fired 20mm bullets and was mainly tested to get some gun data on the M-60 which was then used exclusively by the USAF. Both SUU-23 and SUU-19 were carried by USAF F-4C and D models. Only major difference was that the -19 was RAT driven while the 23 was electrically spun. Good guns that could be very effective against ground targets. Ed, you meant SUU-16, not -19. Guy |

For instance, I've got a shot of Coe and Webb's 34th TFS F-4E waiting to tank P/S after they'd gotten their MiG-21 on 5 Oct. 1972. They were tasked as strike escort, and theyre carrying four AIM-9Es, plus two ALQ-87s forward and a single AIM-7E-2 aft (they got the MiG with the other). Course, they had to sit there and wait for the SAMs and MiGs to a greater extent than you did, plus they turned the pods ON, so I imagine carrying a pair of them was a lot more valuable to them than an extra (and unlikely to be used) AIM-7. The Strike escorts seem to have felt that they were primarily there as Atoll absorbers for the strikers, and comments by COM 7th AF (or maybe it was CINCPACAF, I forget) at the time seem to confirm that was the case. The 432nd MiGCAP guys seem to have carried a full load of AIM-7s and AIM-9s, but also carried two ALQ-87s or -100s, one on each I/B. Guy |

They did run pods "ON" and we never turned them on except as a last-ditch defense in a SAM-dance. But, as mentioned above, we did not have the luxury of uploading and downloading ECM pods for the day's mission. They were bolted on (unjettisonable) and stayed on. As for the likelihood of use--since we were not configured with AIM-9s, we were at least as likely as the escort guys to need an AIM-7. The Strike escorts seem to have felt that they were primarily there as Atoll absorbers for the strikers, and comments by COM 7th AF (or maybe it was CINCPACAF, I forget) at the time seem to confirm that was the case.

Note missing AIM-7!" While I'm normally careful about trusting captions as to details, in the background is a KC-135 along with 3 F-4D strikers, all of which appear to be from the 25 TFS (FA), one of which is on the boom. Coe's a/c, "JJ" 68-0493 is missing an AIM-7E-2 from the aft left well, plus all the tanks, and is presumably waiting his turn on that or another tanker. Oh, and Drendel's source for the photo is Coe himself, so I think in this case we can trust that the date and details are correct;-) Coe himself says he was tasked as the only spare flight lead "for three MiGCAP flights [Sic. Presumably he means escort, as is clearer below] and two flights in support of the Wild Weasels. As soon as I got on the Ground frequency, the leader of the last flight in support of the bombers aborted. He told me to go ahead and take his flight."

We have no disagreement here, Ed. I wasn't referring to duration of time you spent in Indian country, I was referring to the relative freedom to maneuver of the H/K (and MiGCAP) flights compared to strikers, chaffers and escorts. The escorts were tied to the chaffers and strikers, couldn't maneuver freely, and were usually on the edge of the chaff corridor (as you said, outriggers) so the extra jamming power would come in handy. As Coe says, he was tasked as spare flight lead for either strike or WW escort, and his a/c is carrying a pair of pods. They did run pods "ON" and we never turned them on except as a last-ditch defense in a SAM-dance. But, as mentioned above, we did not have the luxury of uploading and downloading ECM pods for the day's mission. They were bolted on (unjettisonable) and stayed on. Well, this and other a/c with the same mission have two "bolted on" in that time frame, judging by the photos. As for the likelihood of use--since we were not configured with AIM-9s, we were at least as likely as the escort guys to need an AIM-7. Given that the AIM-7s were your only missiles, far more so. The Strike escorts seem to have felt that they were primarily there as Atoll absorbers for the strikers, and comments by COM 7th AF (or maybe it was CINCPACAF, I forget) at the time seem to confirm that was the case. Strike escort guys more commonly felt themselves used (abused?) as "herders" to create a situation to turn the MiGs to a place where the fair-haired boys of the 555th could get their shots. We didn't even get to talk to Teaball. Given the number of frequencies you guys had to monitor, I'd say that was a reasonable decision. After all, presumably the escort guys needed to have one radio on the strike (or chaffer, if that was a different frequency), monitor Guard, plus be able to talk to Disco/Red Crown. MiGCAPs were free to engage and AFAIK didn't need tobe on the strike frequency, so letting them talk directly to Teaball makes sense. But it's instructive to look at the 1972 losses to MiGs, and see which taskings took the losses. In Linebacker I strike/chaff escorts suffered exactly half the losses to MiGs, 9/18. The 432nd MiGCAP guys seem to have carried a full load of AIM-7s and AIM-9s, but also carried two ALQ-87s or -100s, one on each I/B. They also had "Agile Eagle" aircraft, the first increment of TCTO-566 modded airplanes with LES and TISEO. And, they had Combat Tree, dedicated GCI support and a serious public-relations corps to make a USAF ace. They were mostly 555th TFS and mostly Fighter Weapons School grads and instructors, so they were arguably the best trained, qualified and equipped to do that mission. Sure. In particular, the 13th/555th Combat Tree F-4Ds used as flight leads always carried a full bag of AIM-7s, because they were the most likely to be able to take a BVR or at least a head-on shot. My point was that, as flights operating well away from the chaff and mass jamming support of the strike flights, and lacking any ability to suppress/destroy SAM and AAA radars, they _needed_ two pods. They seem to have usually had noise/deception ALQ-101s instead of the pure noise jamming -87s which were usually given to the strike and escort flights, which also makes sense. Guy |

Yes, I know, but we're talking about the majority of F-4s, not just your H/K birds. Loads varied depending on the unit and the tasking. My point is that aircraft scheduled for Hunter/Killer and aircraft scheduled for A/A escort, and aircraft that were scheduled as bomb droppers all came out of the basic 27 aircraft that were available to the 34th TFS--24 UE plus 3 attrition spares. Before 1 October '72, when the 469th was still around, the two squadrons were equipped at 18 UE, so the frag drew from those 36 aircraft for whatever mission was required.

As soon as I got on the Ground frequency, the leader of the last flight in support of the bombers aborted. He told me to go ahead and take his flight." Curiosity got the better of me, so I dug out Don Logan's excellent photo anthology, "The 388th Tactical Fighter Wing" by Schiffer Publishing. (As an aside, Don was shot down about three days before I arrived at Korat in '72. I moved into his hootch room even before his personal effects were packed up.) What surprised me was the number of F-4E photos both ground and in-flight in which aircraft had NO ECM pod. Even in photos indicating that they were taken after the commencement of Linebacker operations there is no evidence of a pod. There is a brief account of the Coe/Webb victory, but no mention of pod configuration nor of tank jettisoning. Apparently from that account, he was vectored by Disco to the vicinity of a pair of MiG-21s cruising along in route formation. He sliced down into their six o'clock and got an auto-aq lock-on and fired one AIM-7 for his kill. (So much for the dog-fighting....) All the pictures of pods in Don's book show the pod carried in a forward missile well--none on an inboard wing station (at least at Korat at that time.) In none could I discern carrying two pods. They were tasked as strike escort, and theyre carrying four AIM-9Es, plus two ALQ-87s forward and a single AIM-7E-2 aft (they got the MiG with the other). Course, they had to sit there and wait for the SAMs and MiGs to a greater extent than you did, plus they turned the pods ON, so I imagine carrying a pair of them was a lot more valuable to them than an extra (and unlikely to be used) AIM-7. You are making a bad assumption here. A/A escort flights flew as "out-riggers" on a set of bomb-droppers, usually three or four flights of four. They went in with the bombers and out with the bombers. H/K flights were "first-in/last-out", sweeping ahead of the strikers and remaining in the area until the package was clear--and often beyond that if fuel allowed to do visual armed recce for SAM sites.

As Coe says, he was tasked as spare flight lead for either strike or WW escort, and his a/c is carrying a pair of pods. I'm not enough of an electronic warfare guru to comment on whether carrying a second pod would provide either additional jamming power or broader frequency coverage. Clearly with a straight noise jammer the advantage would be delayed burn-through, but by the time of the ALQ-87 and 101, there was at least as much deception output as noise (as evidenced by the demise of the dreaded "pod roll-in" tactics.) Since resolution pod formation depended on four-ship, there wouldn't have been much benefit to a second pod on what was essentially an autonomous two-ship formation. They did run pods "ON" and we never turned them on except as a last-ditch defense in a SAM-dance. But, as mentioned above, we did not have the luxury of uploading and downloading ECM pods for the day's mission. They were bolted on (unjettisonable) and stayed on. Well, this and other a/c with the same mission have two "bolted on" in that time frame, judging by the photos. As for the likelihood of use--since we were not configured with AIM-9s, we were at least as likely as the escort guys to need an AIM-7. Given that the AIM-7s were your only missiles, far more so. The Strike escorts seem to have felt that they were primarily there as Atoll absorbers for the strikers, and comments by COM 7th AF (or maybe it was CINCPACAF, I forget) at the time seem to confirm that was the case. Strike escort guys more commonly felt themselves used (abused?) as "herders" to create a situation to turn the MiGs to a place where the fair-haired boys of the 555th could get their shots. We didn't even get to talk to Teaball. Given the number of frequencies you guys had to monitor, I'd say that was a reasonable decision. After all, presumably the escort guys needed to have one radio on the strike (or chaffer, if that was a different frequency), monitor Guard, plus be able to talk to Disco/Red Crown. MiGCAPs were free to engage and AFAIK didn't need tobe on the strike frequency, so letting them talk directly to Teaball makes sense. The F-4 add a "one and a half" UHF radio--meaning a transmit/receive primary radio and a receive-only auxiliary channel (with a limited number of pre-set channel choices.) Plus Guard channel, of course. All strike flights after tanker drop-off were on strike primary frequency--Weasels, escorts, bombers, chaffers, jammers, et. al. Disco and Red Crown broadcast on Guard--never any need to talk to them, so that's not a factor. Teaball could have simulcast MiG calls on strike primary to let the guys being targetted know what was going on. They could have let the players know what the MiGCAP was doing. There was no need to talk back to Teaball since we weren't being vectored by them, but to deny guys in the arena essential elements of situational awareness is unconscionable.

Curiosity got the better of me, so I dug out Don Logan's excellent
photo anthology, "The 388th Tactical Fighter Wing" by Schiffer Publishing. (As an aside, Don was shot down about three days before I arrived at Korat in '72. I moved into his hootch room even before his personal effects were packed up.) Don's a member of some Yahoo groups I subscribe to, great guy! _____________ José Herculano |

By that I mean a H/K F-4E during Linebacker was loaded with 4xCBU-52 on the inboard TERs (two on each), three fuel tanks, three AIM-7E-2, and ONE ECM pod in the (usually) left forward missile well. Yes, I know, but we're talking about the majority of F-4s, not just your H/K birds. Loads varied depending on the unit and the tasking. My point is that aircraft scheduled for Hunter/Killer and aircraft scheduled for A/A escort, and aircraft that were scheduled as bomb droppers all came out of the basic 27 aircraft that were available to the 34th TFS--24 UE plus 3 attrition spares. Be that as it may, Coe's a/c wound up with a pair of pods, and it's not the only one. I've got another shot of a 34th bird (68-0498) with a pure A/G load: Mk.84s on the O/Bs, 2 CBUs on each I/B, a C/L, pods in both forward wells, and NO AIM-7s. Both of the 34th TFS birds I've mentioned, Coe's 0493 and 0498, have the long gun blast fairing (given the serials it had to be a retrofit, as they weren't installed on the production line until 69-7261) and formation strip lights, so these photos almost certainly date to the latter half of 1972. I once asked Dweezil when they got the long fairings and striplights, and IIRR he thought not before 1972 for the fairings; I don't remember what he said about the strip lights, but it's clear from photos that neither was a universal fit in 1972, as numerous a/c lack them, especially some of the TDY units like the squadrons from the 4th TFW. Do you remember if both features were present (on at least some a/c) when you arrived in July? I also have shots of A/A loaded 421st F-4Es (per the captions, after the move from DaNang toTakhli) with the same 2 pod/2 AIM-7/4 AIM-9 as Coe's a/c. Before 1 October '72, when the 469th was still around, the two squadrons were equipped at 18 UE, so the frag drew from those 36 aircraft for whatever mission was required. Judging by photo frequency, strikers and strike escorts were often carrying a pair of ALQ-87s in the forward wells by that time, if they weren't carrying a strike camera in place of one of the jammers. Over the years there were a lot of different configurations. Some places and times carried ECM on an inboard wing station. Some carried two pods. Various models of pods were carried and, yes, strike cameras were occasionally hung. For instance, I've got a shot of Coe and Webb's 34th TFS F-4E waiting to tank P/S after they'd gotten their MiG-21 on 5 Oct. 1972. No, from another F-4, probably Coe's wingman. The photo appears in Squadron/Signal's "and kill MiGs" by Lou Drendel, on page 34 of my second edition. The caption reads "F-4E of DickCoe refueling on egress from North vietnam after kill. Note missing AIM-7!" While I'm normally careful about trusting captions as to details, in the background is a KC-135 along with 3 F-4D strikers, all of which appear to be from the 25 TFS (FA), one of which is on the boom. Coe's a/c, "JJ" 68-0493 is missing an AIM-7E-2 from the aft left well, plus all the tanks, and is presumably waiting his turn on that or another tanker. Oh, and Drendel's source for the photo is Coe himself, so I think in this case we can trust that the date and details are correct;-) Coe himself says he was tasked as the only spare flight lead "for three MiGCAP flights [Sic. Presumably he means escort, as is clearer below] and two flights in support of the Wild Weasels. As soon as I got on the Ground frequency, the leader of the last flight in support of the bombers aborted. He told me to go ahead and take his flight." Curiosity got the better of me, so I dug out Don Logan's excellent photo anthology, "The 388th Tactical Fighter Wing" by Schiffer Publishing. (As an aside, Don was shot down about three days before I arrived at Korat in '72. I moved into his hootch room even before his personal effects were packed up.) What surprised me was the number of F-4E photos both ground and in-flight in which aircraft had NO ECM pod. Even in photos indicating that they were taken after the commencement of Linebacker operations there is no evidence of a pod. I've got a fair number of those too (always A/G birds, usually from the 1968-1971 period), and I've always assumed that podless a/c were being sent to SVN or Laos. Presumably you had a limited number of (working) pods, so a/c assignments and tasking would reflect that. These a/c often have a KB-18 in the forward right AIM-7 well, and often no AIM-7s, which again would indicate that they weren't being sent into areas with nothing but manually-aimed AAA. There is a brief account of the Coe/Webb victory, but no mention of pod configuration nor of tank jettisoning. Apparently from that account, he was vectored by Disco to the vicinity of a pair of MiG-21s cruising along in route formation. He sliced down into their six o'clock and got an auto-aq lock-on and fired one AIM-7 for his kill. (So much for the dog-fighting....) Well, sort of. Coe's account in "and kill MiGs" goes into a lot more detail. Coe says he was at about M1.6 and estimates the MiGs were at about M1.1 when he shot, and Webb called a break immediately after the shot, which caused another pair of MiG-21s to overshoot over the top of him (these were probably the ones that had been called merged by Disco, and which caused at least one of the strikers to jettison when the strike flight spotted them). BTW, I believe this is the highest speed attained during a kill in Vietnam, and very possibly the highest speed attained by a tactical a/c during a combat mission. All the pictures of pods in Don's book show the pod carried in a forward missile well--none on an inboard wing station (at least at Korat at that time.) In none could I discern carrying two pods. The 388th carried pods on the I/B prior to the introduction of the pod adapter for the forward wells, at which point the 388th seems to change over completely to carriage in the forward well(s). Judging by the dates in photo captions the adapter wasn't available much before 1972, because I can't find photos of a/c from any of the wings carrying them there prior to that. They were tasked as strike escort, and theyre carrying four AIM-9Es, plus two ALQ-87s forward and a single AIM-7E-2 aft (they got the MiG with the other). Course, they had to sit there and wait for the SAMs and MiGs to a greater extent than you did, plus they turned the pods ON, so I imagine carrying a pair of them was a lot more valuable to them than an extra (and unlikely to be used) AIM-7. You are making a bad assumption here. A/A escort flights flew as "out-riggers" on a set of bomb-droppers, usually three or four flights of four. They went in with the bombers and out with the bombers. H/K flights were "first-in/last-out", sweeping ahead of the strikers and remaining in the area until the package was clear--and often beyond that if fuel allowed to do visual armed recce for SAM sites. We have no disagreement here, Ed. I wasn't referring to duration of time you spent in Indian country, I was referring to the relative freedom to maneuver of the H/K (and MiGCAP) flights compared to strikers, chaffers and escorts. The escorts were tied to the chaffers and strikers, couldn't maneuver freely, and were usually on the edge of the chaff corridor (as you said, outriggers) so the extra jamming power would come in handy. As Coe says, he was tasked as spare flight lead for either strike or WW escort, and his a/c is carrying a pair of pods. I'm not enough of an electronic warfare guru to comment on whether carrying a second pod would provide either additional jamming power or broader frequency coverage. Clearly with a straight noise jammer the advantage would be delayed burn-through, but by the time of the ALQ-87 and 101, there was at least as much deception output as noise (as evidenced by the demise of the dreaded "pod roll-in" tactics.) Checking Jenkins book on the F-105 confirmed my memory that the -87 didn't have deception capability; that was the -101. He writes "Besides laying down a continuous jamming barrage, the ALQ-87 also had a sweep modulator that could introduce random bursts of reinforcing noise in a so-called pulse power option. The pod could simultaneously perform any two of three functions: denying range and azimuth data to Fire Can; depriving Fan Song of range, altitude and azimuth; and jamming the position beacon installed in the sustainer section of the Guideline missile." so carrying a pair of them would certainly add to the jammingpowerandcapability, even if each pod was able to cover the entire threat frequency spectrum (I don't know if they could). Re the -101, he writes "This pod could perform either deception or noise-barrage jamming, and was specifically intended for activities such as Iron Hand [Guy: Also used for MiGCAP by the 432nd in 1972, for the same reason] where formation flying wasn't feasible." Hopefully Bob Payette or others with personal experience of the pods can comment/correct as to band coverage. I've got various conflicting sources. Since resolution pod formation depended on four-ship, there wouldn't have been much benefit to a second pod on what was essentially an autonomous two-ship formation. See above. snip The Strike escorts seem to have felt that they were primarily there as Atoll absorbers for the strikers, and comments by COM 7th AF (or maybe it was CINCPACAF, I forget) at the time seem to confirm that was the case. Strike escort guys more commonly felt themselves used (abused?) as "herders" to create a situation to turn the MiGs to a place where the fair-haired boys of the 555th could get their shots. We didn't even get to talk to Teaball. Given the number of frequencies you guys had to monitor, I'd say that was a reasonable decision. After all, presumably the escort guys needed to have one radio on the strike (or chaffer, if that was a different frequency), monitor Guard, plus be able to talk to Disco/Red Crown.

Disco and Red Crown broadcast on Guard--never any need to talk to them, so that's not a factor. Teaball could have simulcast MiG calls on strike primary to let the guys being targetted know what was going on. They could have let the players know what the MiGCAP was doing. There was no need to talk back to Teaball since we weren't being vectored by them, but to deny guys in the arena essential elements of situational awareness is unconscionable. The 8th tried using the aux. receiver during Bolo for MiG calls. From the summary of the 8th's now de-classified Operation Bolo report: "The Aux. receiver was set up to receive the MiG warnings and other coded calls. However, the west force received very few transmissions over the Aux. Receiver. The east force had satisfactory Aux reception. This was the first time the Aux Receiver had been used for this purpose. Post mission evaluation indicates that the Aux Receiver is too limited in range to fulfill the requirement. The east force was much closer to the transmitting source, therefore, the reception was adequate. The Aux Receiver was designed primarily as a back-up recovery receiver and works off the ADF antenna. It does not have sufficient range capability to be used for this purpose. As for transmitting Teaball on strike primary, crews were already complaining about having their ears blown off and being fed a lot of useless info that didn't apply to them by BigEye/Disco/Red Crown on Guard; would it really make sense for Teaball to routinely step on everyone else on strike primary for info that may only be of interest to the free-ranging MiCAPs, thus potentially blocking a more time-sensitive transmission of greater interest to the strikers? Besides, Teaball appears to have been ballyhooed as much more effective than it was. Other measures seem to have responsible for the improvements which were largely credited to Teaball. Guy |
