The Gulfstream III Private Jet hasn’t been manufactured since the 1980s, but it is still considered one of the best private jets for businesses. It offers fantastic durability and performance even at high altitudes, making it very valuable and cost-effective to a business that wants to get a lot of use out of their jets. In addition, the size of the cabin allows for a lot of flexibility in how you configure the interior to suit the needs of your business or your clientele.
The power and performance for the Gulfstream III comes from the two Rolls-Royce Spey turbofan engines at the back of the jet. Put together, they create over 22,000 pounds of thrust to provide plenty of power, even in reserve, at higher altitudes than other similarly sized jets. The power of the two engines creates a top speed of 576 mph, or 501 knots, with a cruise speed of around 508 mph or 440 knots. It needs a minimum runway of 5,000 feet and can climb 3,800 feet per minute after takeoff.
It has a very aerodynamic windshield to help reduce drag at higher speeds and help its fuel efficiency, and the long wingspan and wing design helps out too. The winglets installed during production in the ‘70s and ‘80s were brand new at the time and are still used among most jets today, which is one of the reasons why it has stuck around as a quality airplane for businesses three decades later. The range of the Gulfstream III can reach close to 4,000 nautical miles, depending on the total weight of the jet and weather conditions during the flight.
The main issue with performance? Those powerful engines are thirsty, and consume an average of 556 gallons of fuel per hour. The ability of the Gulfstream III to maintain high speeds and comfort at high altitudes and through all weather conditions has more than compensated for the fuel efficiency — it’s why it has remained a valuable business jet for so long.
The hallmark of the Gulfstream III is its durability. It wouldn’t hang around for more than thirty years without being highly durable, especially with the power it packs. Starting with the engines, the Rolls-Royce turbofans have a TBO of 8,000 hours, while most business jet engines average less than 5,000 hours.
What really makes the Gulfstream III stand out, however, is the frame of the jet. The manufacturer of its predecessor, the Gulfstream II, had a heritage of engineering jets for naval carriers. Gulfstream purchased the company before designing the Gulfstream III, allowing it to keep the almost military-grade durability of the frame, while adding new features designed for businesses and greater luxury.
The other benefit of the Gulfstream III comes from it being so popular, and having other models that use the same parts — replacement parts are very affordable and easy to find. This means you can overhaul your engine and replace broken or worn parts for cheap, allowing you to keep your operating costs down in spite of the suboptimal fuel efficiency.
Depending on the age of the specific plane, you might have to install a hush kit in order to meet newer noise compliance regulations. However, you can relatively easily and cheaply install high-quality hush kits to further dampen the engine noise, in order to create a more quiet and luxurious environment for those in the interior.
The relative affordability and durability of the Gulfstream III means that you can put more money into upgrading the interior however you want. With a cabin size of just over 1,300 cubic feet, you can fit between 12 and 19 seats depending on how you arrange everything. You can add brand new furniture including leather seats, on-board Wi-Fi, and full entertainment centers with all the latest technology.
