Experts think the business jet industry will grow from $25.87 billion in 2021 to $36.94 billion by 2028. This surely means more innovative jets are to come, but it could also increase sales for popular standbys like the Gulfstream GIV.

If you’re familiar with the Gulfstream GIV, then you know why this aircraft is so sought-after. It’s the perfect aircraft for international and domestic business travel. With 664 aircraft remaining in operation and over 900 initially manufactured from 1985 to 2018, this aircraft offers performance, dispatch reliability, and one of the best cabins in the industry.

Read on for a look into the history of the Gulfstream GIV and more about its specifications. In addition, we’ll take a look at the entire Gulfstream GIV family and highlight each model’s features.

History Of The Gulfstream GIV

Designed and built by Gulfstream Aerospace based in Savannah, Georgia, the Gulfstream GIV gained its type certificate in 1985. Its last model, the Gulfstream G450, topped off a 30-year production run in 2018.

Design began in 1983 in collaboration with the now-closed Grumman Aircraft Engineering Corporation. The goal was to create a long-range business jet with elevated comfort in mind. In addition to its speed, this aircraft offered a whole new level of luxury in the two Rolls-Royce RB.183 Tay turbofan engines. It’s fixed with Honeywell’s avionics package and is known for its ability to travel far and fast.

Additional Use Of The Gulfstream GIV

However, its uses go beyond leisure travel alone. The National Oceanic and Atmospheric Administration’s (NOAA) National Hurricane Center and Hurricane Research Division also use the GIV. Its purpose is to help researchers follow and collect data from tropical cyclones to help scientists better predict future hurricanes and other storms. And it does a great job at doing so because of its speed, range, and space for researchers and their equipment.

Furthermore, variants of the GIV were made for military use, equipping the Department of Defense with the C-20F (also G, H, and J).

The Difference Between Models

The Gulfstream GIV went with four models known as the GIV, GIV-SP, G350, and finally, the G450. While they had many things in common, newer models were upgraded to improve capacity, range, and performance over time.

The design team extended later models to make more room within the cabin. The cockpit was made larger, and its range improved. Another version altered the range to produce a shorter-range vehicle in the G350 purposefully.

The final two models, the G350 and G450, experienced an engine switch upgrading from the Rolls-Royce Tay 611-8 to the Rolls-Royce Tay 611-8C. The newer engine model offers cast HP1 turbine blades, a larger fan from the 650-15, a structural by-pass duct, and a full authority digital engine (FADEC).

Other points of improvement include:

  • Speed
  • Noise levels
  • Emissions
  • Fuel economy
  • Range
  • Cargo capacity
