The F-15 Eagle utilizes the WRM tanks extensively during combat operations. The tank differs from the standard Eagle tank by having the rear aerodynamic fairing removed and a blunt plate installed. It has a look very similar to an F-16 standard wing tank. These tanks have been extensively researched and reproduced by Richard Van Zandt. They are the only ones I know of in 1/48 available today.
