The next production version of the Thunderjet was the F-84E.  The F-84E 
had the same engine as did the P-84D--the Allison J35-A-17D, rated at 
5000 pounds of thrust.  However, there were quite a few changes added 
to the fuselage.  The F-84E had a Sperry APG-30 radar ranging 
gun-sight, improved wingtip tanks for combat use, and a 12-inch 
extension to the fuselage to provide more space for the pilot in the 
cockpit.  Retractable jet assisted take-off (JATO) racks were added to 
the underside of the rear fuselage, raising the maximum takeoff weight 
to 22,460 pounds.  Internal fuel capacity was increased from 416 US 
gallons to 452 US gallons.  Two 230-gallon tanks could be carried at 
the wingtips, bringing the total fuel capacity to 912 gallons and 
giving a range of 1485 miles.  In addition, the fuel system was 
modified to allow a 230-US gallon tank to be carried under each inner 
wing shackle, enabling a ferry range of 1950 miles to be attained.  

The first F-84E was ordered on December 29, 1948, and the first 
example (49-2022) flew on May 18, 1949.  In all, 843 F-84Es were 
built.  

The F-84E was the version that equipped most of the six USAF wings 
using Thunderjets when the Korean War began.  It was first taken into 
combat on December 7, 1950 by the 27th Fighter Escort Group, which had 
reequipped from F-82E Twin Mustangs only a couple of months earlier.  

The 27th's F-84Es were initially assigned to B-29 escort duties, in 
the course of which they were engaged in frequent combat with MiG-15s.  
The first F-84 MiG kill took place on January 21, 1951.  However, the 
straight-winged F-84E was much too slow to match the swept-wing 
MiG-15, and MiGs were often able to slip through the escort screen and 
make successful attacks on B-29s.  The total air-to-air score ended up 
as nine MiGs downed as opposed to 18 Thunderjets lost, which gave the 
Thunderjet a 2 to 1 inferiority against the MiG-15.  

The task of dealing with the MiGs was left to the more capable F-86 
Sabre, and the Thunderjets were transferred to ground attack duties, a 
task at which they excelled.  The F-84 replaced the F-80 in the 
fighter-bomber role in the 49th, 58th, 116th, and 474th Wings.  The 
F-84E and the later F-84G flew a total of 86,400 sorties and delivered 
55,897 tons of bombs.  122 Thunderjets were lost to antiaircraft fire.  
Perhaps the two most spectacular Thunderjet operations of the Korean 
War were the attacks on the Toksan irrigation dam on May 13, 1953, and 
the raid on the Chusan irrigation dam three days later.  

Specification of the F-84E: One Allison J35-A-17, 5000 lb.st.  Maximum 
speed: 613 mph at sea level Initial climb rate 6061 feet per minute.  
Service ceiling 43,220 feet.  Normal range 1485 miles.  Maximum range 
1950 miles.  Weights were 10,205 pounds empty, 14,724 pounds gross, 
22,460 pounds maximum takeoff.  Dimensions were wingspan 36 feet 5 
inches, length 38 feet 7 inches, height 12 feet 10 inches, wing area 
260 square feet.  Offensive load included two 1000-pound bombs, or two 
1200-lb 11.75-inch "Tiny Tim" rockets carried on the inboard underwing 
pylons.  For short ranges, an array of 32 five-inch rockets could be 
carried underneath the wings.  

F-84E-20-RE serial number 50-1143R is on display at the Wright 
Patterson Air Force Base Museum in Dayton, Ohio.
