The F-16N Viper, a version of the F-16 Fighting Falcon operated by the US Air Force, was procured by the US Navy for use as an adversary aircraft in air combat training, simulating the capabilities of fourth-generation Soviet fighters.
The F- 16N as it was designated was based on the standard F-16C variant flown extensively by the USAF.
The F-16N was outfitted with the Air Combat Maneuvering Instrumentation (ACMI) pod on the starboard wingtip.
The Navy had been looking for a replacement to its aging fleet of adversary aircraft, specifically the A-4 Skyhawk and F-5 Tiger.

Flown Slick, it must have been the perfect hot rod !

That plane has been sitting in the boneyard since Jan of 1995.  

14 or 16?

I thought the Navy still had F-16's.. just not the original batch of N's?

The Navy has Pakistani embargoed F-16's.
Not as much of a hotrod as the F-16N was.

in 2002, the Navy began to receive 14 F-16A and B models from the Aerospace Maintenance and Regeneration Group (AMARG - the Boneyard) that were originally intended for Pakistan before being embargoed.
These aircraft are operated by the Naval Air Warfare Development Center (NAWDC) / (TOPGUN) for adversary training and like their F-16N predecessors are painted in exotic schemes.
Thus, TOPGUN has had the benefit of flying against F-16s as dissimilar aircraft since 2002-03.
As these jets age, NAWDC is currently considering a new adversary aircraft, and among the contenders is the F-16V Block 70 Viper.

It could supercruise.

Despite what you may have read, there are a lot of 4th gen fighters that can supercruise. I could even do it in a clean 229-powered F-15E.

That is so cool! I would modify one further slicking it even more and with larger internal tanks to fly around the country.
