NEW YORK, March 13 (Reuters) - Gulfstream Aerospace Corp on Thursday launched the new G650 business jet, its biggest, fastest, longest-range plane to date, as it looks to take advantage of the continuing boom in private plane sales and the trend toward larger aircraft.

The G650, priced at just under $60 million, will have a range of 7,000 nautical miles (about 12,950 km) at a speed of 0.85 Mach, which means it would be able to fly non-stop from Los Angeles to London.

It will have a maximum cabin headroom of about 6 feet 5 inches (1.96 meters) and larger, oval windows. The plane is set for first test flight late next year and first delivery in 2012.

Gulfstream, a unit of defense contractor General Dynamics Corp (GD.N: Quote, Profile, Research), is pricing the jet at $59.5 million each, but early customers can expect discounts, a common practice in the aviation industry.

The Savannah, Georgia-based company caters to the upper end of the business jet market, but has recently seen potential customers opt for versions of larger commercial planes made by Boeing Co (BA.N: Quote, Profile, Research) and Airbus.

Last year Saudi billionaire Prince Alwaleed bin Talal became the first individual to buy an Airbus A380, the largest commercial plane in production. Boeing has sold nine of its new 787 Dreamliners to superwealthy private customers.

Gulfstream's new G650 jet, the designs of which were unveiled at its main plant early on Thursday, wouldn't compete directly with those larger airliners, but is designed to dominate the top end of the business jet market.
