Hi Harold,
Venezuela received 24 F-16s between 1983 and 1985. These were 18 F-16A and 6 F-16B, all built to Block 15 configuration. Originally they were armed with AIM-9P-4 as the main air to air armament, the typical Mk.8x series of bombs with slik and AIR tails, CBUs on (to me) an unkown type and Durandal anti-runway munitions.
Starting in the early 90's they started getting some modifications. The first of these was the addition of a new ISN system (I have the specific type, but not with me here at the office). Later it also received the Elisra SPS-1000 RWR, and the FAV also got AIM-9Ls for its Vipers. In 1997 the FAV received its firsts Litening navigation and targeting pods, and a unspecified number of GBUs, including GBU-10 Paweway IIIs. As part of the work, the standard F-16A Block 15 display was changed for a modern MFD. More recently the original F-100-PW-200 engines were upgraded by Samsung in Korea to the PW-220E model.
So far 3 F-16's have been lost in accidents (two B serials 2179 and 9581, as well as one A, 6611). 9581 and 6611 appaerently went down due to bird strikes and subsequent loss of engine power, and all three pilots ejected. However, 2179 was apparently caused by human error when practicing a routine for an airshow in 1995. Both pilots were killed.
Should you want more detail feel free to ask and I'll provide you with what I can.
May I ask what the novel is about?
