Supporting the F-5 Aggressor Fleet

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. Keeping them in service requires maintenance contracts – and some timely help from the Swiss…
Contracts and Key Developments
Unless otherwise noted, The Naval Air Systems Command in Patuxent River, MD manages the contracts.
Jan 11/09: Sikorsky Aerospace Maintenance in Stratford, CT receives a $34.7 million modification to a previously awarded firm-fixed-price contract (N00019-09-C-0024), exercising an option for organizational, selected intermediate, and limited depot-level maintenance for 44 F-5 aircraft operated by American adversary squadrons.
Work will be performed at the Naval Air Station (NAS) Key West, FL (40%); NAS Fallon, NV (30%); and the Marine Corp Air Station, Yuma, AZ (30%), and is expected to be complete in December 2010. All contract funds will expire at the end of the current fiscal year, on Sept 30/10.
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.
