Um....more and more interesting.
Re:
@ rondondo: Well the soviets probely would have known that the US was trying this , because the soviets also were designing merchant ships with ballistic missile's. Nut i think it would have been a hard nut to crack for th KGB.
Agreed, the Soviets would have been onto this pronto, and would have naturally devoted a lot of assets to tracking any merchant ship wandering about without any port of call.
@ Portsmouthbill: I think they would have build multiple ships , flagged in multiple NATO coutries, I dont think the ship would fly a NATO flag because that would give it away , altrue it does have US Sealift Command stripings on its funnel, could be just a standard cargo vessel.
Sure, and I wasn't being literal about actually displaying the NATO flag; more that the vessels woul be under NATO command - hence the mutinational crew, and in itself one of the factors mitigating against the project - the USA would not have been keen to supply Polaris with the potential security risks.
In a sense, it could hide everywhere. On sonar and radar, it would just be another merchie.
I'm not so sure about this; the Soviets would have been following the movements of any suspicious ships, and in extremis would probably sink all merchant ships in the wrong spot and with similar displacement and appearance to the NATO 'Q' ships.
All very interesting, but never seriously considered as a viable project.
