News stories on VOCM and in the Telly today discuss a ship docked at Portland, Me that may be a telemetry vessel supporting the launch tomorrow of the last Titan 4B rocket from Canaveral air force station. The Telly story isn't on line.
To get some other information, here's the original story from Portland, in the Portland Press Herald. Here's a story with a photo of the ship, a converted offshore supply vessel. Here's an Associated Press version of the story, sans photo.
The SAGE appears to be owned by a company in Louisiana, called Tidewater, that specializes in the supply of offshore vessels. Some of their ships, as this link indicates, have been adapted for other uses.
For those wanting some boilerplate on the vessel, such as registration data, gross tonnage and construction, here's a detailed link.
This vessel is carrying temporarily installed equipment on the rear deck. The domes presumably shield radar systems of an unknown type. They are mounted on trailers or other temporary shelters housing equipment and support crew.
There has been plenty of speculation on the Internet on this launch and on the appearance of this ship in Portland. Spec is fun; but I will take a closer look and see if I can figure out something a bit more concrete on this.
