This model is in 1/700 scale. The aircraft are unarmed but have three external fuel tanks under the fuselage. The 12x F-15 Strike Eagle aircraft are connected as a single sprue by a wire under the nose of the aircraft. Once the wires are cut the model does not require finishing.
According to Wikipedia: "The McDonnell Douglas (now Boeing) F-15E Strike Eagle is an American all-weather multirole fighter, derived from the McDonnell Douglas F-15 Eagle. The F-15E was designed in the 1980s for long-range, high speed interdiction without relying on escort or electronic warfare aircraft. United States Air Force (USAF) F-15E Strike Eagles can be distinguished from other U.S. Eagle variants by darker camouflage and conformal fuel tanks mounted along the engine intakes."
