See Joe Baugher article at http://home.att.net/~jbaugher1/f102_1.html part of which I quote below. The XF-92A is the aircraft which did not have "area rule". Tex The F-102 project was in serious trouble, and if a fix for the performance problems could not be found, the entire project was in danger of cancellation. While eight more YF-102s (Model 8-82, serials 53-1779/1786) were being built to the same standards as the first two aircraft, Convair embarked on a major investigation and redesign program in an attempt to save the F-102. The salvation of the project turned out to be in the "area rule" devised by NACA scientist Richard Whitcomb. According to the area rule, the total cross sectional area along the direction of flight should be a constant in order to achieve minimum transonic drag. In order to achieve this, it was required that the fuselage be narrowed down in the region where the wing roots were attached, then broadened back out again when the wing trailing edge was reached. This gave the aircraft fuselage a characteristic "wasp-waist" or "Coke-bottle" shape. In order to achieve this, the length of the fuselage was increased by 11 feet, and a pair of aerodynamic tail fairings were added aft of the trailing edge, these fairings extending beyond the end of the afterburner tailpipe in a pair of characteristic protrusions. These tail fairings were for purely aerodynamic purposes and had no other function. A new cockpit canopy with a sharper leading edge was fitted, although it had an adverse effect on overall visibility. Cambered leading edges were fitted to the thin delta wings to improve the behavior of the thin airfoil at high angles of attack, and the wingtips were given wash-in. |

In message m, David
E. Powell writes Third. did the F-102 have a gun or just internal missiles in a weapon bay? Falcon missiles (six IIRC) in the bay, plus 24 x 2.75" rockets (launch tubes in the bay doors). From memory there were twelve tubes each with two rockets nose-to-tail: this was sometimes downloaded to twelve, and F-102s in Vietnam did some very light ground attack (using their IR sensor to find targets like campfires and the rockets to engage). My recollections may be at variance with the facts, so check before using ![]() *There was a massive "Was GENIE a rocket or a missile" debate on another group, which I won't get into here. I think the verdict was a rocket, which it was, guided missile or not. Unguided (and hence unjammable, but demanding to use correctly) -- When you have to kill a man, it costs nothing to be polite.

I think the verdict was a rocket, which it was, guided missile or not. Unguided (and hence unjammable, but demanding to use correctly) Jack Broughton was less than confident about the Genie's accuracy. He compared firing one to tying a piece of string around your finger and the other end around the trigger of a shotgun. When you wanted to fire the shotgun, you threw it away from you and it fired when the string pulled taught, with the accuracy you'd expect under such conditions. He goes on (I've left his spelling unchanged): "Two specific cases made me a non-Geenie [sic] fan. The first Geenie that was test-fired from an F-106 came right back up, blew the nose off the aircraft, and killed the pilot. Years later I got a chance to go to Tyndal [sic] with my F-106 squadron. ADC had saved their resources too well and wound up with a large number of Geenies that only had a few days to go before they would run out of shelf life and have to be destroyed. The plan was to fire as many of them as fast as we could, so for a week straight we saturated the Gulf of Mexico with every Geenie that we could get to accept the firing signal and leave our aircraft. They took off in all directions, but very seldom towards the target drones. One particular Geenie turned hard left as I fired and I watched it do lazy concentric barrel rolls as it headed straight down to my left. I knew that if it was for real the boom only had to be close, but suppose straight down and to the left was the area I was supposed to be defending? Well, the other theory of the times was that we would be intercepting all the invading bombers way up north someplace, where I wouldn't know anybody living off to my lower left."

I have seen the debate over GWB as an F-102 pilot, so I was wondering about a couple of things. First, was the F-102 taken out of service in the early 1970s? I have to ask because as a kid I remember the Guard around here flying F-106s up to around 1990 or 1991 or so, and they were closely related to the F-102. Though I recall them being (much) faster. Mach 1.8 vs. Mach 2.32 IIRC. HANG (Hawaii) flew 102 until 1977 (last unit as best I can find out). Now the be TOTALLY correct Deuce was flown much longer than that as drone. The Six was faster due to the fact that F-106 had engine with more thrust (J75 vice J57). Not sure, but don't think Deuce had variable inlet either (open to correction) The six also had an area-ruled fuse, that is significant for a +mach bird. Actually, Al, the 102 used area rule--the lack of area rule resulted in the first protype YF-102 being firmly subsonic. Redesign to incorporate area rule yielded the F-102A, which was our first supersonic interceptor. Brooks Al MInyard OOOOPS, thanks for the correction, I was probably thinking of pictures of the prototypes. A;l Minyard |

Whoa - Considering how long they served I would have thought the opposite. Maybe it was felt they had better odds against bombers. Or there was some sort of upgrade by the '80s. Considering alot of ANG fighters that escorted bombers up and down the seacost in the Cold War carried them. I wonder if GWB ever flew with the nuclear version....? DEP Maybe that's why the F-106 got a cannon.... -- When you have to kill a man, it costs nothing to be polite. W S Churchill Paul J. Adam MainBoxatjrwlynch[dot]demon{dot}co(.)uk |

The real deal is that most F-106s were decoys, by the mid 1970s. |
