[QUOTE="Krieg, post: 1101396, member: 5282"] It cost aprox $200 mil to originally build the Explorer in the early 70's. She was refitted a few years ago & leased to Global Marine Drilling for use as a deep sea drilling platform. The refit cost aprox $180 mil & was completed in '98. The Explorer has a length of 619ft & a beam (width) of 116ft. She has a draft of 35ft & weighs 63,000 tons. The internal "moon pool" was aprox 200 ft long. The Explorer was the sole ship built of it's type, but was based upon the older (and smaller) Glomar Challenger.

Anytime the President is aboard a Marine Corps aircraft that aircraft becomes "Marine One". Just as any AF aircraft becomes "Air Force One". Similarly (but less commonly) if he is on an Army bird it becomes "Army One" while a civilian aircraft would be callsign "Executive One". The rest of the time any of the aircraft use their normal callsigns. FWIW The Marine squadron that flies the VH-3Ds for the President is HMX-1. They also have VH-60Ns, CH-53Es & CH-46E in their inventory. [/QUOTE]
