In early 1984, Boeing and Pratt & Whitney announced that they would 
engage in a joint Phantom modernization program, targeted primarily at 
foreign users of the Phantom.  McDonnell had already turned down a 
similar idea, citing the fact that the Phantom was already old 
technology and fearing that Phantom upgrades would compete with their 
F-15 Eagle, which they also hoped to sell on the export market.  

The "Boeing Super Phantom" (as the project came to be known) was to 
have been powered by a pair of Pratt & Whitney PW1120 turbofans.  This 
engine was based on the F-100 turbofan which powered both the F-15 and 
the F-16, and had about 70 percent commonality with the F-100.  The 
PW1120 turbofan was 40 inches shorter than the J79 and 25 percent 
lighter in weight.  However, it had 35 percent greater dry thrust and 
30 percent greater afterburner thrust.  It was anticipated that the 
use of the new powerplants would give a marked improvement in Phantom 
performance, with sustained turn rate being increased from 9 to 10.5 
degrees per second and initial climb rate being increased from 42,300 
to 51,000 feet per minute.  

The aircraft was also to have had a 1100-US gallon conformal fuel tank 
fitted onto its belly.  This tank was to have had hard points on it 
for four bombs or two Sparrow air-to-air missiles.  Such a tank could 
carry nearly twice the fuel of the standard centerline drop tank of 
the Phantom and offered only 29 percent of the drag.  The forward nose 
landing gear was to have folded inside a forward faring in the tank, 
and the rear fairing of the tank was to have carried an AN/ALE-40 
chaff/flare dispenser.  

The electronics were also to have been upgraded, with various options 
being made available to fit specific customer requirements.  Among the 
options being proposed were the fitting of a GEC heads-up display, a 
Honeywell 423 ring laser gyro inertial navigational system, and APG-65 
radar.  

Boeing envisaged the establishment of cooperative programs between it 
and indigenous aircraft companies in the customer's own country.  
However, before anything could be produced, the Air Force's 
Aeronautical Systems Division suspended all work on the Boeing Super 
Phantom.  The Boeing "Super Phantom" was quietly shelved.
