bullet100 Posted November 24, 2018 Share Posted November 24, 2018 Hi all Does anyone know if the F-4N had the belly strengthening plate added as part of the upgrade? Quote Link to post Share on other sites
Wild Weasel V Posted November 24, 2018 Share Posted November 24, 2018 I'm certain the F-4N didn't have a belly reinforcing strap installed. The primary reason for the strap was to compensate for the additional loads introduced by the slats on the F-4E and F-4S when so retrofitted. The only non-slatted variants I definitely know that received the belly strap were the F-4J(UK) and some FGR.2s late in service. The F-4J(UK) was effectively a slatless F-4S and the FGR.2s were modified to extend their service lives due to the delays in introduction of the Tornado F.3. I don't think this was needed to happen on the F-4N as they were probably replaced by the F-4S long before their fatigue life limits expired. You might find this interesting: http://aviationarchives.blogspot.com/2016/12/seven-wings-f-4-phantom-ii-has-flown.html However if anyone has definitive evidence that the F-4N was fitted with the strap, I too would be interested in seeing it.
