Wiki mentions civilian usage of the aircraft, but does not specify any exact roles. Photomapping? Executive transport? Firefighting?
The Wiki page on the F-15 copied the specifications from the P-61B and only changed the top speed. So if you want to do a bit of community service, prevent any poor SOBs from falling for false numbers.
700+ kph for a piston is right down my alley.
I Wouldnt say they copied the P-61B specs. That would be partially incorrect, BUT, the RF-61 had a most unique and unconventional design history..
You see, Johnny Myers ( The P-61 chief test pilot ) Made a pitch to the airforce ( directly ) for a fast long range twin engine fighter with four machine guns in the nose. That design was for the P-61E. The P-61E was a P-61B with the hump on the back and the Radar position in the tail removed, and was the basic design you see in the pictures here in this thread. The army/airforce, then decided that wth the war ended, they didnt need a long range bomber escort, But did have a need for a photo reconnaissance vehicle. Northrop responded to this need with a P-61C which like the B before it, had the hump and turret removed its nose modified to hold I think eleven different types of cameras and its forward frame reinforced to handle the weight of the cameras. This became the original F-15 Reporter.
Confused yet?? I was..
So, remember that poor little P-61E Escort fighter ( ok, Not so little )?? The airforce did need a bomber escort, but chose to go with the F-82 Twin Mustang, for reasons no one to this day can fully fathom. the P-61E had its guns removed to be replaced by the standard F-15 array of cameras and reinforcements. It became the only truly streamlined version og the RF-61 to exist as the P&W 2800-65 engines didnt use the annular mounted supercharger inlet scoop like the F-15s that were made from P-61C's..
Regarding weight speed and power.
The P-61B/P-61E used the Pratt and Whitney R-2800-65 Engine producing 2250 HP and had a top speed of 360 MPH with military power and 410 mph with war emergency power.
The P-61C/F-15 reporter utilized the Pratt and Whitney R-2800-73 engine producing 2800 HP which provided a top speed of 440 MPH using Military power..
Weight is contested to this day. Dry weight is quoted as being either 21,000 pounds or 22,000 pounds. Max weight, depending on the source varies between 34000 pounds to 37000 pounds.. DC1973s FDE is based on the lower weights..
Anyway.. Now that ive confused everyone, its back to my drawings and calculators..
