In the 1980s movie Top Gun, the revolutionary “MiG-28s” operated by the enemy air force were actually F-5E Tiger IIs, derived from a family of fighters whose design concept dates back to the mid 1950s. The F-5 family of aircraft were produced in large numbers, as they were an extremely popular export item; many are still operated by countries around the world.
“F-5Ns” are routinely flown by American Navy and Marines “aggressor” squadrons in training exercises, where they simulate the small, low-cross-section (and hence hard to spot) enemies that gave American pilots such trouble in Vietnam…

Unless otherwise noted, The Naval Air Systems Command in Patuxent River, MD manages the contracts.
May-June 2009: US Defense Acquisition University’s Defense AT&L Magazine runs “Sharpening the Spear Through Innovative Acquisition: The F-5 Adversary Program” [PDF]. It describes the US Navy and Marine Corps’ purchase of 44 Swiss F-5s from 2003-2005, in a “reverse Foreign Military Sale.”
Switzerland had originally purchased 70 F-5E/Fs from the USA in the late 1980s, but sharp cuts to the Swiss Air Force had left them with surplus planes. The Swiss aircraft had far lower flight-hours per airframe (average flight hours: 2,500) than American aggressor training squadron F-5Es (average flight hours: 7,000). They also added a number of useful improvements: an improved inertial navigation system, new radar warning receiver capability and chaff /flare capability, added anti-skid capability, improved airborne radar capability, and standardized cockpit configuration.
With Northrop Grumman’s close cooperation, the entire program was accomplished within a $43 million budget, avoiding a situation in which 73% of the Navy and Marines’ F-5 aggressor aircraft were expected to drop out of service by FY 2007 due to spiraling maintenance costs. The ex-Swiss planes can be identified by their new designation: F-5N.

Dec 17/08: Sikorsky Support Services, Inc. in Stratford, CT received a $6.6 million modification to a previously awarded firm-fixed-price contract for organizational, selected intermediate, and limited depot-level maintenance for 44 F-5 aircraft operated by the Adversary Squadrons based at Naval Air Station (NAS) Key West, FL; NAS, Fallon, NV; and Marine Corps Air Station, Yuma, AZ.
Work will be performed in Key West, FL (40%); Fallon, NV (30%); and Yuma, AZ (30%), and is expected to be complete in February 2009. All contract funds will expire at the end of the current fiscal year (N00019-01-C-0109).
Oct 22/08: NAVAIR’s Support and Commercial Derivative Aircraft program office is upgrading the Navy’s F-5N Adversary aircraft with new avionics, and expects to save an estimated $20 million in future costs. Jay Bolles, Adversary Integrated Product Team lead:
“The cost to repair the older INS and buying a new, more capable system was about the same so the decision was made to go with the newer, more reliable system…. The funding for the entire $6.1 million upgrade program was split between the U.S. Navy Reserve, which fly the F-5Ns, and the Support and Commercial Derivative Aircraft program office.”
Northrop Grumman’s new LN-260 inertial navigation system and new display bring a multi-function touch screen capability, a radar display, INS functions, embedded Global Positioning System (GPS) and a new fiber optic gyro. NAVAIR release.
Aug 25/08: Sikorsky Support Services, Inc. in Stratford, CT received a $10.5 million modification to a firm-fixed-price contract (N00019-01-C-0109) that began in 2001, in return for another year of organizational, selected intermediate, and limited depot-level maintenance for 44 F-5 aircraft operated by the USA’s adversary squadrons based at Naval Air Station (NAS) Key West, FL (40%); NAS Fallon, NV (30%); and Marine Corps Air Station, Yuma, AZ (30%).
Maintenance may be marginally easier this year, thanks to a smart NAVAIR program involving the F-5’s internal batteries. Work is expected to be completed in December 2008, and contract funds in the amount of $3 million will expire at the end of the current fiscal year on Sept 30/08.
