A couple more photos of Top Aces (adversary or aggressor for hire) ex-Israeli A-4N aircraft. The top photo shows a new splinter paint scheme and also shows the A-4N with three external fuel tanks. It looks to me like the underwing tanks are 300-gallon versions while the centerline tank is the 400-gallon version. There was also a 150-gallon version that was rarely seen after the 1950s. Note that the Douglas-developed fuel tanks have a shape very much like the Mark 8X series of bombs, such as the Mark 82 500-pounder and the Mark 84 2,000-pounder.
Infrared search and track has been around for years. It's a method to detect an adversary without emitting a radar signal. Now Top Aces have fitted their A-4N with an IR search and track system. See the second photo. Those A-4s are like the Energizer bunny... they just keep going and going!
