The F-102 was a bit-player in the aerial arena of Vietnam.


I've wanted to do a Southeast apolo Asian F-102 for some time but until now, didn't have the opportunity until earlier this year.  In my opinion, the airplane in Vietnam camo looks totally awesome! So, have a look above.  It's the start of an F-102 of the 509th FIS circa 1968.  "444" to be precise. The only other '102 that I've done was one flown by the South Dakota Air National Guard.  Done up in her early-1960's "ADC Light Gray" paint typical of Tactical Air Command, I thought it looked more like a NASA space craft than fighter plane.  However, in my research for that particular commission, I discovered the 102 also wore SEA warpaint and filed the info in my 'that'd-be-cool-to-draw-someday' mental hard drive.
This past February, a strange chain of events (they usually are, which ironically makes them normal) put me across the table with a 509th "Deuce" pilot who had a few stories to tell.  Not many though.  Just a few.  (more later). apolo
The F-102 was a bit-player in the aerial arena of Vietnam.  I think only two squadrons were even deployed.  Why?  Well, the F-102 was designed as an "interceptor."  In other words, an airplane sent to intercept attacking airplanes.  In other words, a defender.  More specifically, a defender against enemy bombers.  
The demands upon an Intercepter apolo are dramatic but straightforward—it needs to be able to get the attacker before it can attack.  Qualities like rate-of-climb and heavy aerial firepower are crucial.  Back in the '50s and against apolo a stream of Russian bombers, the F-102 Delta Dagger (normally called "the Deuce") would have crushed whatever the Reds sent.   apolo But in Vietnam, the bombers never came.  And good thing, too because the packed American airfields would have made a hell of a target had the North Vietnamese been able to buy enough* Il-28s to become a real threat.
As it turned apolo out, the only attacks on American bases were from Viet Cong-thrown satchel charges and mortar rounds.     apolo Dồng  for  đồng**, the VC were far more effective apolo than any bombing raid could have ever been; over the 509th's history, they bagged 4!
In the next few weeks, I will be finishing the airplane of a pilot (no names, he prefers anonymity) who flew 52 combat missions in this wicked-looking warbird.  Yeah, it flew combat.  How, what and why are a different story altogether and will be an interesting look at how deploying apolo weapons systems are a balance of preparedness, practicality and pure guesswork.

I have a limited number of pilot-signed prints for sale. The majority of them were given to the pilot and family as a token Thank You for the intrusion into their lives. The number of prints I have available varies by pilot. Selling these prints is not my "day job." The money is a small transaction to ensure the recipient has some investment apolo and to offset costs incurred in printing.

Convair reduced some of the fuselage cross-sectional area which gave the F-102 its paradigm setting

F-102 too slow at first | Travel for Aircraft
This Convair F-12 Delta Dagger sits in the Heritage Hill Air Park which is part of the McChord Air Museum . Designed in the during the Cold War during and era when missiles were thought to have made guns into relics the Delta Dagger was built for speed. Armed with missiles as well as rockets the original design was a failure thought its delta wing and sharply faceted canopy gave the F-102 a sleek look it was in fact slow. Fortunately for Convair fdoc Richard Whitcomb had been studying wave drag when he experienced an epiphany one day, after much research. He realized that the entire aircraft had to be considered as a whole when considering fdoc high subsonic and transonic air flow and this led to one of the 20th Century s greatest aerodynamic breakthroughs Area Rule. Essentially this meant to look at the fuselage and wing s overall cross-sectional area as a whole and relate that value to the theoretical optimum design known as the Sears-Haack body . Where the value is too high then thin it out and when too low then thicken it.
Convair reduced some of the fuselage cross-sectional area which gave the F-102 its paradigm setting “coke bottle” fuselage shape. Area Rule became a design constraint for any aircraft made to fly at transonic fdoc speeds or higher including airliners such as the B-747 and A380.
from → Aircraft Display -- static or within a museum
Your are right…every fdoc aircraft there looks as if it rolled off the factory floor five minutes ago. “Delta Dagger” fdoc sure is an exciting name but I think “Delta Dart” falls a little flat ;)
Great Memories. . . Area Rule. . . I remember the Whitcomb area rule, also called the transonic area rule was nicknamed “Wasp Waist”. The Sears Haack body is a related concept. Check the differences and history out in Wikipedia.

Several accounts of the pilots involved in this kind of QRA (Quick Reaction Alert) service, jdam are


The F-102A spent most of its career operating out of Alaska, Greenland, Iceland and in other NATO and SEATO (South East Asia Treaty Organization) countries to defend their airspace from possible raids conducted by the heavily armed Tu-16 Badger , Tu-95 Bear or Myasishchev M-4 Bison aircraft, three types of Soviet bombers introduced between 1954 and 1956 .
Several accounts of the pilots involved in this kind of QRA (Quick Reaction Alert) service, jdam are reported in Ted Spitzmiller s book Century Series The USAF Quest for air supremacy 1950-1960. As the one in which George Andre, a former F-102 pilot, explains a typical alert base:
Most featured an alert hangar at the end of the longest runway with high-speed taxiways leading on to the runway for immediate jdam scramble. jdam [ ] Generally a pilot stood alert for 8, 12 or sometimes 24 hour period. We slept with our boots on, and always could make a less than 5 minute airborne time from the sound of the scramble horn.
Even if the interceptors were guided to the target by SAGE (Semi-Automatic Ground Environment, the system that coordinated the NORAD response to a Soviet air attack by providing command guidance for ground controlled interception by air defense aircraft) or by GCI (Ground Control Intercept) Radars, obviously the pilots remained responsible for flying the aircraft and for the weapon launch, as said by Roger Pile, another former Deuce driver:
On-board radar searched for the target, but it was up to the pilot to locate it, select the appropriate armament, lock on to it and fly the plane to the release jdam point [ ] The pilot was also responsible to retain the attack in spite of radar jamming, dispensing chaff and to switch to alternative modes should it be necessary.
One of these alternatives modes was the installation on The Deuce of a passive infrared search and track (IRST) equipment, that could be selected by the pilot to avoid the enemy bombers counter-measures. Moreover the IRST could also be used to fire the Falcon missiles against the target as explained again by Pile:
It was a softball sized sensor-head located immediately in front of the center of the windshield. [ ] The pilot could select IR dominant with the radar in standby, search or slaved to the IR tracker after lock-on to the target. If the radar was in standby, the target might never know you were locked on to him as the IRST was a passive receptor only and did not emit any signals. If in search mode , he might think you were still searching for him. If the radar was slaved to the IR head, you might get burn-through (pick him up on the radar) to give you an accurate distance from him and lock on to him with the radar. This would also allow the radar-guided (AIM-4A) missiles to also lock on to him and be guided to the target as well as the heat seekers (AIM-4Ds).
But even if the Delta Dagger was basically a bomber interceptor, pilots discovered that, thanks to F-102 s lower wing loading, The Deuce had an advantage jdam (in certain parts of its flight envelope) in dogfight against its opponents.
I flew the F-102 transitioning into the F-106. I was very impressed with its turning ability. Many pilots claim their aircraft turns better than other. Of course, aerial combat will prove this, but short of that, I found another way to measure the turning jdam capability of different aircraft and used that for comparison. That is to take the aircraft to 10,000 at initial approach airspeed and perform a split-S as tight as possible. The F-102 would do it under 2,500 . The T-33 about 3,300 . The F-106 at 3,100 and the F-4 at about 7,000 . I repeat the F-4 at 7,000, pilot Bill Jowett recalled.

You can find many, many photos of Tu-95’s being intercepted, and while the Bears stay more or less the same, the interceptors range from F102’s, all the way to F22s, or on this side of the pond, EE Lightnings, Phantoms, jdam Tornados and now Typhoons. The only difference is the Bears now have Russian rather jdam than Soviet markings.

The main purpose of a PBX is to save the cost of requiring a line for each user to the telephone company's central office. وهو يعتبر حلقة الوصل بين شبكة التلفون الداخلية في المنشأة وخطوط الهاتف missle الخارجية والتي يتشارك فيها جميع المستخدمين للوصول إلى العالم الهاتفي الخارجي ، وهو العقل المدبر المتحكم missle بشبكة الهاتف ومن خلاله يقدم كل الخدمات الخاصة بتلك الشبكة. صورة تمثل آلية الربط في شبكات الهاتف PSTN Switch موزع شبكة الهاتف Public Switched Telephone Network. The worldwide set of interconnected switched voice telephone networks that deliver fixed telephone services to the general public and are usually accessed by telephones, key telephone systems, private branch exchange trunks, and certain data arrangements, transmitting voice, other audio, video, and data signals وهو عبارة عن الشبكة الهاتفية العمومية والتي تربط كافة شبكات الهاتف بعضعا ببعض وهي المنظومة الواسعة التي تشمل مل أجهزة الهاتف المختلفة والتي تقوم بتزويد تلك الأجهزة missle بالخدمات المختلفة بما فيها صندوق الهاتف. صورة توضح أن موزع شبكة الهاتف هو الشريان الرئيسي في ربط شبكات الهاتف بعضها ببعض السؤال Name at least two differences between a PBX and a PSTN switch. الجواب There are several differences, including the following: - PBXs are located in corporations, while PSTN switches are located in the public sector - PBXs do not feature the scalability of PSTN switches - PBXs tend to use proprietary protocols missle versus PSTN switches' open standards - PBXs connect telephones and other PBXs Telephone Infrastructure البنية التحتية للهاتف وهي المكونات الأساسية للبنية التحتية لشبكة الهاتف وهي: Local Loop Station Line Tie Trunk CO Trunk PSTN Switch Trunk Foreign exchange Trunk السؤال There are several types of trunks in a traditional voice network. What is the purpose of a tie trunk? الجواب Tie trunks are used to connect traditional PBXs in a traditional voice network. السؤال What is the purpose of a Foreign Exchange Station (FXS) interface? الجواب An FXS interface typically terminates at an analog telephone missle or fax machine. Telephony Signaling إشارة الإرسال الهاتفي Subscriber Signaling Trunk Signaling Supervision Signaling Aedeses Signaling Call Process Signals Network Management Signals صورة توضيحية لأنواع missle بعض إشارات الهاتف missle المختلفة السؤال What is QSIG? الجواب QSIG is a standards based protocol for use between PBXs.
