Northrop
E/F- 5E Tiger II1972)

The F-15E's deep-strike mission is a radical departure from the original intent of the F-15 since it was designed as an air-superiority fighter under the mantra "not a pound for air-to-ground." The basic airframe, however, proved versatile enough to produce a very capable strike fighter. The F-15E, while designed for ground attack, retains the air-to-air lethality of the F-15, and can defend itself against enemy aircraft

E/F- 5E Tiger II1972)

The Northrop F-5 is a family of supersonic light fighter aircraft initially designed as a privately funded project in the late 1950s by Northrop Corporation. There are two main models, the original F-5A and F-5B Freedom Fighter variants and the extensively updated F-5E and F-5F Tiger II variants. The design team wrapped a small, highly aerodynamic fighter around two compact and high-thrust General Electric J85 engines, focusing on performance and a low cost of maintenance. Smaller and simpler than contemporaries such as the McDonnell Douglas F-4 Phantom II, the F-5 cost less to procure and operate, making it a popular export aircraft. Though primarily designed for a day air superiority role, the aircraft is also a capable ground-attack platform. The F-5A entered service in the early 1960s. During the Cold War, over 800 were produced through 1972 for U.S. allies.

Design

The design effort was led by Northrop vice president of engineering and aircraft designer Edgar Schmued,[7] who previously at North American Aviation had been the chief designer of the successful North American P-51 Mustang and F-86 Sabre fighters. Schmued recruited a strong engineering team to Northrop[8] and assigned them the goal of reversing the trend in fighter development towards greater size and weight in order to deliver an aircraft with high performance, enhanced maneuverability, and high reliability, while still delivering a cost advantage over contemporary fighters.[9][10] Recognizing that expensive jet aircraft could not viably be replaced every few years, he also demanded “engineered growth potential” allowing service longevity in excess of 10 years.[11] Schmued recognized that new jet engine and aerodynamic technology were crucial to these goals, such as the compact but high thrust-to-weight ratio General Electric J85 turbojet engine, and the recently discovered transonic area rule to reduce drag. The J85 engine had been developed to power McDonnell’s ADM-20 Quail decoy employed upon the Boeing B-52 Stratofortress.

Northrop E/F 5E Tiger II (1972)

The Swiss Air Force flies a total of 22 F-5E and four F-5F aircraft, down from a peak of 98 and 12 in 1981.[100] They were chosen chiefly because of their excellent performance, suitability for the unique Swiss Air Force mission, and their relatively low maintenance cost per flight hour.

It had been expected these aircraft would be replaced by the Saab JAS 39 Gripen, but in May 2014, a referendum by the Swiss people decided against the purchase of the Gripens.[101]

For the foreseeable future, the Swiss Air Force will continue to fly its present F-5s. There are still plans by the Swiss Air Force and in the Swiss parliament to fly 18 F-5E and four F-5F models. This would also include the continued operation of the Patrouille Suisse, in F-5Es until 2018

The F-5 was also developed into a dedicated reconnaissance version, the RF-5 Tigereye. The F-5 also served as a starting point for a series of design studies which resulted in the Northrop YF-17 and the F/A-18 naval fighter aircraft. The Northrop F-20 Tigershark was an advanced variant to succeed the F-5E which was ultimately canceled when export customers did not emerge.
