Boeing B-17 Flying Fortress Papermodel Download

The Boeing B-17 Flying Fortress was a four-engine heavy bomber aircraft developed in the 1930s for the then-United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry outperformed both competitors and more than met the Air Corps' expectations. Although Boeing lost the contract because the prototype crashed, the Air Corps was so impressed with Boeing's design that they ordered 13 more B-17s for further evaluation. From its introduction in 1938, the B-17 Flying Fortress evolved through numerous design advances.

The B-17 was primarily employed by the United States Army Air Forces (USAAF) in the daylight precision strategic bombing campaign of World War II against German industrial and military targets. The United States Eighth Air Force based at Thorpe Abbotts airfield in England and the Fifteenth Air Force based in Italy complemented the RAF Bomber Command's nighttime area bombing in Operation Pointblank to help secure air superiority over the cities, factories and battlefields of Western Europe in preparation for Operation Overlord.The B-17 also participated to a lesser extent in the War in the Pacific where it conducted raids against Japanese shipping and airfields.

From its pre-war inception, the USAAC (later USAAF) touted the aircraft as a strategic weapon; it was a potent, high-flying, long-range bomber that was able to defend itself, and to return home despite extensive battle damage. It quickly took on mythic proportions, and widely circulated stories and photos of B-17s surviving battle damage increased its iconic status. With a service ceiling greater than any of its Allied contemporaries, the B-17 established itself as an effective weapons system, dropping more bombs than any other U.S. aircraft in World War II. Of the 1.5 million metric tons of bombs dropped on Germany by U.S. aircraft, 640,000 tons were dropped from B-17s.

Grumman F-14 Tomcat Papermodel Download

The Grumman F-14 Tomcat is a supersonic, twin-engine, two-seat, variable-sweep wing fighter aircraft. The Tomcat was developed for United States Navy's Naval Fighter Experimental (VFX) program following the collapse of the F-111B project. The F-14 was the first of the American teen-series fighters which were designed incorporating the experience of air combat against MiGs during the Vietnam War.

The F-14 first flew in December 1970. It first deployed in 1974 with the U.S. Navy aboard USS Enterprise (CVN-65), replacing the F-4 Phantom II. The F-14 served as the U.S. Navy's primary maritime air superiority fighter, fleet defense interceptor and tactical reconnaissance platform. In the 1990s it added the Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) pod system and began performing precision strike missions.^[1] The F-14 was retired from the active U.S. Navy fleet on 22 September 2006, having been replaced by the F/A-18E/F Super Hornet. As of 2009, the F-14 was only in service with the Islamic Republic of Iran Air Force, having been exported to Iran in 1976 when the US had amicable diplomatic relations with the nation.

F-15I Ra'am (Thunder) Papermodel Download

Boeing’s (formerly McDonnell Douglas) F-15E Strike Eagle entered service with the IDF/Heyl Ha’Avir (Israeli Air Force) in January of 1998 and was designated the F-15I Ra’am (Thunder). The F-15E Strike Eagle is the ground attack variant of the F-15 air superiority fighter, capable of attacking targets day or night, and in all weather conditions. The F-15I serves alongside the F-15C, which has seen considerable combat since introduction into the Heyl Ha’Avir in 1976.
Israel has bought F-15A, B, and D aircraft from USAF inventories and is currently obtaining an air-to-ground version called the F-15I. The two seat F-15I, known as the Thunder in Israel, incorporates new and unique weapons, avionics, electronic warfare, and communications capabilities that make it one of the most advanced F-15s. Israel finalized its decision to purchase 25 F-15Is in November 1995. The F-15I, like the US Air Force's F-15E Strike Eagle, is a dual-role fighter that combines long-range interdiction with the Eagle's air superiority capabilities. All aircraft are to be configured with either the F100-PW-229 or F110-GE-129 engines by direct commercial sale; Night Vision Goggle compatible cockpits; an Elbit display and sight helmet (DASH) system; conformal fuel tanks; and the capability to employ the AIM-120, AIM-7, AIM-9, and a wide variety of air-to-surface munitions.

Northrop-Grumman UCAV Papermodel download

An unmanned combat air vehicle (UCAV) or "combat drone" is an experimental class of unmanned aerial vehicle (UAVs). They differ from ordinary UAVs, because they are designed to deliver weapons (attack targets) – possibly with a great degree of autonomy. The elimination of the need for an onboard human crew in a combat aircraft that may be shot down over enemy territory has obvious advantages for personnel safety. In addition, much equipment necessary for a human pilot (such as the cockpit, flight controls, oxygen, seat/ejection seat, etc.) can be omitted from an unmanned vehicle, resulting in a decrease in weight possibly allowing greater payloads, range and maneuverability.

Current UCAV concepts call for an aircraft which would be able to operate autonomously. It will be programmed with route and target details, and conduct the mission without help from human controllers.

Lockheed F-117 Nighthawk Papermodel Download

The Lockheed F-117 Nighthawk is a stealth ground attack aircraft formerly operated by the United States Air Force. The F-117A's first flight was in 1981, and it achieved initial operating capability status in October 1983. The F-117A was "acknowledged" and revealed to the world in November 1988.

A product of the Skunk Works and a development of the Have Blue technology demonstrator, it became the first operational aircraft initially designed around stealth technology. The F-117A was widely publicized during the Persian Gulf War of 1991. It was commonly called the "Stealth Fighter" though it was an attack aircraft, making its F-designation misleading.

The Air Force retired the F-117 on 22 April 2008, primarily due to the fielding of the F-22 Raptor and the impending fielding of the F-35 Lightning II.

McDonnell Douglas F-15 Eagle Papermodel Download

The McDonnell Douglas (now Boeing) F-15 Eagle is a twin-engine, all-weather tactical fighter designed to gain and maintain air superiority in aerial combat. It is considered among the most successful modern fighters with over 100 aerial combat victories with no losses in dogfights.^[3][4] Following reviews of proposals, the United States Air Force selected McDonnell Douglas' design in 1967 to meet the service's need for a dedicated air superiority fighter. The Eagle first flew in July 1972, and entered service in 1976. The F-15 is expected to be in service with the U.S. Air Force until 2025.^[5]

Since the 1970s, the Eagle has also been exported to Israel, Japan, and Saudi Arabia. Despite originally being envisioned as a pure air superiority aircraft, the design proved flexible enough that an all-weather strike derivative, the F-15E Strike Eagle, was later developed, and entered service in 1989.
