Just for the record, the S-3 was not a good tanker! 3000 & 1500 lbs for mission and recovery tanking, respectively. It just filled a void. It was ok at ASW, depending on crew currency and equipment status (shit was old). It was very good at SSC. The radar though lacking color was very good especially once locked in the ISAR mode. I forget max "give" tanking numbers but it still wasn't great even as a yo-yo. It had plumbing issues which limited its "give". But it was a fun though ugly jet and I'm sure the 1000+ hours didn't hurt the resume.
A slightly modified S-3 redone as a KS-3 would be a nice addition though and it would save some wear and tear on the SH's.
