Military Aircraft L/D Ratio Question

I'm wondering what the L/D ratios of the following aircraft are, my fascinating largely has to do with the difference between aircraft designed for subsonic flight, and those designed for supersonic speeds.

Any information is appreciated assuming it's not classified

CARGO

C-141A Starlifter
  • At the start of the cruise, typical cruise & mach number
  • At the middle of the cruise, typical cruise & mach number
  • At the end of the cruise, typical cruise & mach number

C-5A Galaxy
  • At the start of the cruise, typical cruise & mach number
  • At the start of the cruise, typical cruise & mach number
  • At the end of the cruise, typical cruise & mach number


FIGHTERS

F-86E Sabre
  • At cruise mach-number & altitude: clean
  • At cruise mach-number & altitude: -w- drop-tanks

F-101C Voodoo
  • At cruise-mach & altitude: clean
  • At cruise-mach & altitude: -w- 2 x 450-gallon tanks
  • At supersonic/top-speed, high-altitude: clean

F-104C Starfighter
  • At subsonic cruise-speed & altitude: clean
  • At subsonic cruise-speed & altitude: -w- wingtip-tanks
  • At subsonic cruise-speed & altitude: -w- wingtip & underwing tanks
  • At Mach 2, high-altitude: clean
  • At Mach 2, high-altitude: -w- wingtip-tanks
  • At Mach 2, high-altitude: -w- wingtip & underwing tanks

F8U-2/F-8C Crusader
  • At cruise mach-number & altitude: clean
  • At cruise mach-number & altitude: typical air-to-air load-out.
  • At supersonic-speed & altitude: typical air-to-air load-out.


BOMBERS

B-36A Peacemaker
  • At typical cruise mach-number & altitude
  • At maximum altitude

YB-49
  • At typical cruise mach-number & altitude
  • At maximum altitude

  • At typical cruise mach-number & altitude w/o drop-tanks
  • At typical cruise mach-number & altitude -w- drop-tanks

B-58A Hustler
  • At takeoff-speed: Fully-fueled w/o external weapons-pod
  • At takeoff-speed: Typical operating weight (163,000 pounds)
  • At landing-speed and weight: w/o external weapons-pod
  • At landing-speed and weight: -w- external weapons-pod
  • At subsonic-cruise mach-number & altitude: w/o external weapons-pod
  • At subsonic-cruise mach-number & altitude: -w- external weapons-pod
  • At supersonic-cruise mach-number & altitude: w/o external weapons-pod
  • At supersonic-cruise mach-number & altitude: -w/ external weapons-pod

XB-70A Valkyrie
