F-105 Thunderchief

C L I C K     T O     E N L A R G E

The F-105 is history's largest single seat, single engine combat aircraft.  It was developed in the early 1950s with its primary role that of delivering a large, tactical nuclear weapon.  The mission called for flying fast and low to the ground and characteristics making for an effective fighter aircraft were given secondary consideration.  The illustration above is 502 x 350 and is by Jerry Boucher.  It is posted at Vectorsite.

Nearly half of the 800 F-105s built were lost over Vietnam, most brought down by ground fire, 32 by SAMs and 22 were shot down by MiGs.  The Thud flew daily operations over North Vietnam during the three years of Rolling Thunder.  A typical mission payload would be eight 340 kg (750 lb) bombs secured to wing pylons.  The photo above is 550 x 350 and is from Aerospace Web.

Thud pilots were required to fly 100 missions before rotating out of the Vietnam theater.  Well before that number was reached the odds of successfully completing a sortie were definitely working against them.  Two F-105 pilots received the Medal of Honor for action over North Vietnam.  The picture is 439 x 640 and is posted on Reddit.

A two seat version of the F-105 was used for SAM missile suppression, a role referred to as Wild Wiesel.  These aircraft were the first in and the last out and carried armament specifically designed to knock out radar and the launch sites for the dreaded SA-2 surface to air missile.  The above labeled graphic is 605 x 697 and is from Air Force World.

Modifications to the F-105 added to its weight and increased its drag to the point where Mach 2 speeds were no longer attainable.  The power plant was never upgraded as the Air Force instead looked ahead to replacing the Thunderchief with more advanced aircraft.  The illustration above is 1024 x 738 and is from Cybermodeler.

Despite the fact that the F-105's bomb bay was used for additional internal fuel storage and the jet also carried two large drop tanks on its wings most every mission routinely involved aerial refueling because of the Thud's rapid consumption of fuel.  It is no coincidence that the F-105's designer, Alexander Kartveli, also designed the very large World War II fighter, the P-47 Thunderbolt.  The picture above is 1800 x 1405 at 300 dpi and is seen at Air Refueling Archive.

Equipment providing advanced targeting capability required lengthening the nose beyond that of the original F-105.  Other additions included ECM or Electronic Counter Measure devices used to thwart the radar guidance of SA-2 missiles over North Vietnam.  The picture is 1024 x 768 and is from Space Chimp.
