How quickly the United States could build twelve strike cruisers

How quickly could the United States build twelve strike cruisers if construction began in 1980?

The first pair might arrive in 1983, but the full class would probably take until about 1989 or 1990.

Yard throughput sets the schedule more reliably than the size of the initial order. Two yards might keep roughly three hulls in production at once, with the first pair entering service around 1983 after a 1980 start. Subsequent pairs could follow annually if the program were pushed hard. Even under that favorable rhythm, completing all twelve would more plausibly take until 1989 or 1990.
