No probs at all, just a little clarification on the US way of making submarines and the misconception of how the laid down date is not all that is seems with the US compared to the UK, it does not tell the full story.Thanks for the insight with regards to the UK production. Was not aware of this.
The block iv uss Vermont the most recent sub that was built, was launched 18 months after being laid down and was commissioned after about 3 years of being laid down. Wonder if there was a refinement in the production program or possibly a reorganisation of the build process? I think the 6-7 year time frame you mentioned was possibly for the earlier blocks.
There are 2 yards in the US that are capable of building nuclear powered submarines, GD Electric Boat and Newport News Shipbuilding.
Each yard is responsible for building specific blocks of each boat, they also take it in turns, think it is still the case, on the reactor plant, blocks are then sent to the required yard for consolidation, they alternate as to who actually put the blocks together and final integration, fitout etc.
The US says laid down when these blocks are brought together for integration and final assembly and fitout, this is what skews the dates, as opposed to the UK only having one yard so they start their "laid down" time from a much earlier stage of block construction and consolidation,
Hope that make sense
