Found on ebay a while back, an artists concept (almost certainly an AP artist, using imagination more than primary documentation) showing an odd little submarine carrying four Polaris missiles while would launch through the sail. Such concepts *were* studied early on in the process, but I think this one is pure artistic license.
The Polaris was a model of the unmanned Skyjack used in the Voyage To The Bottom Of The Sea in the Rise of the Machines episode.
