The Concorde is not worlds first supersonic airliner, Tu-144 is. By first flight, 12/68 vs. 3/69, as well as EIS, 12/75 vs. 1/76.
Also the carrier version of the Su-27 is also known as Su-27K (for Korabelniy, loosely equivalent to Naval)
And one last thing, C-47 is not "the military variant", it is merely the "US Army designation(variant, if you will)". There is the Navy R4-D (hope I got this right), which is military, and the RAF Douglas Dakota, which is military as well.
