In 1963, at the 25eme Salon International de l'Aeronautique et de l'Espace (Le Bourguet - Paris, June 6-16), Republic Aviation Corporation (Farmingdale, Long Island, N.Y.) released the following text and official photographs to Aviation and Aerospace VIPs and journalists to describe its general activities at that time.
After more then three decades as one of the leading aircraft manufacturers, Republic Aviation Corporation's activities have expanded to cover a wide spectrum of advanced aircraft, electronics and space system development and procedures.
To illustrate Republic's diversified interests, the company is now engaged in the production of the F-105D Thunderchief, and a two-place version of this versatile Mach-2 all-weather fighter-bomber, the F-105F, and in research projects ranging from a major study of space re-entry problems to space environment and life sciences research, development of advanced scientific satellites, space propulsion systems and revolutionary metalurgical, communications and hydraulics developments.
In the past year, work on 51 research and development contracts, including 13 for the National Aeronautics and Space Administration, was conducted at Republic as part of the continued development efforts fostered by the comapny since its founding in 1931 as the Seversky Aircraft Corporation.
Since that founding with a handful of employees, Republic has grown ta an industrial city of 18,000 scientists, engineers, techniciens and production specialists working in 60 buildings on 535 acres of ground at Farmingdale, Long Island.
Since 1931, Republic has produced nearly 25,000 aircraft. Its renowned family of military aircraft has progressed from the 230-mph P-35 fighter of the thrities, to the famed P-47 Thunderbolt flown by air forces of six allied nations during World War II, the F-84G Thunderjet which bore the brunt of combat in the Korean War, the F-84FThunderstreak fighter-bomber and RF-84F Thunderflsh reconnaissance aircraft,workhorses of the air arms of 14 western nations, and the versatile F-105, the world's first Mach-2 all-weather figther-bomber now in service with the USAF in Europe, the U.S. and the Far East.
The evolution of Republic aircraft development continues today with pioneering work in a unique design for a strike-reconnaissance fighter combining the capability for vertical takeoff and landing (VTOL)and the versatility of the variable-geometry wing which can be extended for slow, loiter missions or withdrawn to a delta-like shape for Mach-1 low-level or Mach-2 high altitude missions.
Other aeronautical programs under study and in various forms of development at Republic include controls research for Mach-2 supersonic transport, studies of a lightweight fighter-bomber for limited war applications, of a high-speed interceptor and of what has been called the "aerospace plane". While much of this aircraft is classified, it can be reported that it would be capable of taking off as conventional aircraft, then accelerating to orbital speeds to circle the Earth and perform missions anywhere over the globe. Its speed would be about 25 times that of sound.
In addition, Republic has dramatically expanded its efforts in space-oriented research and development, including the addition to its facilities of the $14 million Paul Moore Research and Development Center. The many capabilities of the center have generated more than 60 research contracts, including some in 30 new technical areas. Some of these activities are:
Republic's development experience in electronic guidance and control systems has also led the company into such diverse areas as the production of submarine simulators to train crews in control operations of atomic attack class submarines; precision radar antenna assemblies; automatic checkout equipment for aircraft communications, identification, navigation and radar systems; an all-weather guidance system for the air-to-ground Bullpup missiles and a low-cost, propeller driven drone, called the Bikini, which can be launched from a battlefield, flown over enemy lines to photograph installations and be recovered by parachute.
In July 1965, only two years after the above press release was made at the 1963 Paris Airshow, Republic Aviation Corporation ceased to exist as an independent company and became the Republic Aviation Division of Fairchild Hiller (also called Fairchild Republic). The Republic Aviation Division was shut down in 1987 after Fairchild Industries decided to stop producing commercial or military aircraft.

The F-105 Thunderchief is a single-place (except for the modified F-105C and F-105F trainer/wild weasel aircraft) supersonic fighter-bomber manufactured by the Fairchild Hiller Corp., Republic Aviation Division in Farmingdale, New York. It is a swept-wing, single engine, aircraft developed to meet the USAF requirement for a supersonic fighter-bomber aircraft that could deliver a single nuclear bomb at high-speed and low-altitude to targets in the Eastern block countries during the cold war. The F-105 was developed in the early 1950s and the first flight was in 1955, with the YF-105A. The first F-105B was delivered in 1958, whereas the last F-105F two-seater aircraft was delivered in 1965. The development of the F-105F crew stations has been described extensively in a Fairchild Hiller report (Fairchild Hiller, 1963) and included the initial construction of life-size cardboard versions and an aluminium mock-up to test different instrument configurations and lighting conditions.
In 1963, at the 25eme Salon International de l'Aeronautique et de l'Espace (Le Bourguet - Paris, June 6-16), Republic Aviation Corporation (Farmingdale, Long Island, N.Y.) released the information below about its F-105D Thunderchief aircraft, with two official photographs.
The Republic F-105D Thunderchief, the world's first Mach-2 fighter-bomber capable of operation in any weather or visibility conditions, has added a new dimension to the tactical air power of the U.S. Air Force.
The versatile Thunderchief, capable of delivering both conventional and nuclear weapons, is the latest in a long line of renowned fighter-bombers developed by Republic Aviation Corporation during its more than three decades as one of the United States' leading aviation and aerospace industries.
A descendant of Republic's famed P-47 Thunderbolt of World War II and the F-84F Thunderstreak now serving with the air forces of 14 countries of the Free World, the Thunderchief is operated by Tactical Air Command units in the United States and the U.S. Aris Forces in Europe and the Pacific. Since 1955, Thunderchiefs have logged some 138,489 hours of flight, equivalent to 7,700 trips around the world.
A new two-place version of the Thunderchief, designated the F-105F, is scheduled for delivery to the U.S. Air Force later this year. The F-105F will have the same mission capabilities of the single-seat F-105D and is expected to greatly strengthen pilot mission training programs.
Use of the two-seat F-105F is expected to provide twice as much pilot time per hour of flight and to eliminate the need for use of non-combatant jet trainers and chase planes during training.
The F-105 is the first tactical aircraft designed to incorporate the ideas and recommendations of the men who operate it - pilots and operations and logistics experts of the Tactical Air Command.
Its speed, which tops 1,400 miles per hour (2,240 km per hour), its maneuverability and its aerial firepower have qualified it for some 15 different types of missions in either limited or general war situations.
|Specifications - F-105D Thunderchief|
|Power||One Pratt and Whitney J-75 F-19W jet engine. More than 25,000 pounds of thrust on employing afterburner and water injection.|
|Speed||Mach-1 at low level, Mach-2 at high altitude.|
|Span||34 feet, 11 inches.|
|Height||19 feet, 8 inches.|
|Armament||Carried internally and externally, various combinations of nuclear or thermonuclear weapons, 6 tons of conventional bombs, napalm bombs, clusters of rockets, or guided missiles for air-to-ground or air-to-air missions. Vulcan automatic 20-millimeter cannon, firing 6,000 rounds per minute.|
|Range||Global when using in-flight refueling.|
The F-105 can operate as a fighter-bomber in close support of any ground troops. Its ability to climb from a standstill to 8,200 feet at supersonic speeds in 55 seconds augment its role as an interceptor for air defense operations. Its more than 2000 mile range, without refueling, and global range, with mid-air refueling, highlights its capability as a bomber.
The size of the Thunderchief permits it to carry up to six tons of weapons, surpassing the payload of any previous tactical aircraft. An almost unlimited choice of weapons combinations can be carried, ranging from sixteen 750-pound bombs to Sidewinder missiles for air-to-air combat and Bullpup air-to-ground missilesand napalm fire bombs for close support of ground troops.
The Thunderchief's firepower also includes the lethal Vulcan automatic 20-millimeter cannon, capable of firing 6,000 rounds per minute, resulting in each impacting with a force equivalent to an auto traveling at 450 miles per hour smashing into a brick wall.
An integrated navigational, fire control and flight control system gives the F-105D its all-weather capability. This highly advanced system allows a pilot to take off, fly to the target and release convetional or nuclear weapons without ever seeing the ground.
The Thunderchief's electronics systems, proven in more than 100,000 operational flying hours, has provided an around-the-clock capability never before possible with previous aircraft.
Operating the Thunderchief in Europe are the 49th and 36th Tactical Fighter Wings of 17th Air Force, the operational arm of the U.S. Air Forces in Europe. A squadron of F-105B Thunderchiefs, equipped for air defense interceptor missions, was recently assigned to Moron Air Base, Spain, on rotational duty from the Tactical Air Command's 4th Tactical Fighter Wing based at Seymour Johnson Air Force Base, South Carolina.
The F-105D and F-105F are part of a wide range of advanced aircraft and space system programs under way at Republic, including development of a dramatic new concept in tactical strike-reconnaissance aircraft which combines vertical take-off and landing capabilities with a variable geometry wing.
Later in the 1960s, Republic's F-105 Thunderchief played a significant role in bombing North Vietnamese targets during Operation Rolling Thunder, with close air support of the F-4 Phantom, during the Vietnam war. No other aircraft has put as much ordnance on North Vietnam targets. Pilots used to fly a fixed route to Hanoi targets following a mountain range and valley, that is now known as Thud Alley. Jacksel M. Broughton, an F-105 pilot stationed at Takhli Air Force base in Thailand, has written a very informative book on this subject titled Thud Ridge, published in 1969 by Hanson B. Baldwin and later by Bantam War Books.

In May 1961, the F-105 was also stationed for the US Air Force in
Europe (USAFE) in Germany at Bitburg and Spangdahlem Air bases
(49th Tactical Fighter Wing's 8th Tactical
Fighter Squadron). The jets patrolled the skies close to the Iron
Curtain. The graphic below shows Thuds flying over the Rhine River and
various squadron shields.

A detailed view of the F-105F nose section design is shown below. This blueprint image was taken from Republic Aviation Corporation's 1963 report on the Configuration and arrangement of crew stations for two-place F-105F-1-RE airplane. (Elect/Equip Report No. 192. Farmingdale, Long Island, New York). It shows how the pilots were seated in the cockpit and the various electronic equipment in the space below the cockpit. This equipment included the airconditioning unit, the ASQ-37 communication and navigation system, the air data system, electrical power systems, computer/flight director systems, etc.
Flight (1960) published an overview of the electronic
equipment inside the F-105. This included weapon systems ballistic
computers, communication, navigation and identification (CNI) systems,
automatic flight control and stability augmentation, IFF, etc. A picture of
the black boxes in the F-105 is shown below.
Promotional material and flight manual illustrations provide a look into the graphic design that was in fashion in technical papers in the 1950s and early 1960s. Below are some examples of artwork of Republic Aviation.
Below are several images illustrating flight and reference manual artwork and their final versions as displayed in the F-105B flight manual of 1969.
The following 1960 advertisement for the F-105 Thundercheif displays the advanced systems incorporated in the aircraft.
The Republic F-105 also featured in advertisements of manufacturers of its systems, such as in the advertisement below published in a magazine for the Collins Radio Company AN/ASQ-37 communication, navigation and radar identification (CNI) system that included UHF, Tacan, ADF and intercom systems.
Scale models such a the one shown below were handed out to aviation and aerospace VIPs and to the fighter pilots flying these birds when they reached a certain number of combat missions flown (e.g. 100).
Two companies produced these contractor models for Republic in the U.S., being Topping Inc. from the mid-1950 (metal model, 1/50 scale), followed by Precise Models, Inc. in the 1960s (various resin models). The Dutch M.M. Verkuyl produced F-105D Thunderchief models in Europe for Republic. These were made by melting rejected pistons from KLM propeller aircraft. More information on these contractor scale models is presented on my Topping Inc., Precise Models Inc. and Matthijs Verkuyl models web pages.
Below is a library of original and digital aviation books, flight manuals and factory reports that served to provide the information on the F-105 Thud.
