A JAMES MADISON Class (627-636) is a variant of the LAFAYETTE Class (616-626)
Identical in every way to the Lafayette's and originally to be part of that class, these boats were originally fitted with the slightly longer range Polaris A-3 over the A-2 installed in the first 9 boats.
Slight differences internally and in displacement.
