The average time to build an Ohio-class (Trident) submarine was approximately 4 years between laying the keel and launching, with another year after launching until commissioning (5 years total). There were early problems with the new modular construction process which initially ran into cost overruns, but once those were sorted out, it became the new standard for submarine construction.
The last Ohio-class boat, the USS Wyoming(SSBN-742), was launched in 1991 and commissioned in 1996.
