Gulfstream Readies Long-Secret Jet Company still keeping quiet about P42 project By Matt Cantor, Newser User Posted Oct 13, 2014 12:25 PM CDT 19 comments Comments A Gulfstream G450 business jet, left, is displayed during the Asian Aerospace Show in Hong Kong, Tuesday, March 8, 2011. (AP Photo/Kin Cheung) (Newser) – There have been murmurs of the existence of Gulfstream's upcoming business jet for years, but not until tomorrow will the world finally get to see it. The company is set to show off the project—currently called P42, but due for a name change—tomorrow in Savannah, Ga., the Wall Street Journal reports via insiders. Even now, though, the company isn't officially saying what tomorrow's event is all about. Details about the jet are scant, but it was made "from scratch," the Journal reports, and it runs on a new engine by Pratt & Whitney Canada—making it the first Gulfstream jet of its kind not to use a Rolls-Royce engine in 50 years, the Savannah Morning News reported this summer. The new jet is likely to fly some 5,000 nautical miles. As for the inside, the jet will likely be in the Super Large cabin category, with a luxury interior aimed at corporations and the very rich. The project prompted Gulfstream to add some 2 million square feet to its facility, says an analyst. It's intended to replace the current G550 and G450 models, the Journal notes.
