The Gulfstream G-100 and G-150 are mid-size business jets, with the G-150 being an improved version of the G-100, featuring a wider cabin, better avionics, and increased range, both known for their high speed and performance in the mid-size business jet category, originally manufactured by Israel Aerospace Industries (IAI) and later acquired by Gulfstream, with the G-100 initially called the IAI Astra SPX; the G-150 offers a significantly more spacious cabin compared to the G-100, making it a more comfortable option for longer flights
