The GNAT 750 effort squeaked through, and in early 1994 the CIA sent a team equipped with a GNAT 750 to Albania to monitor events in the former Yugoslavia. The operation was not a success. The aircraft suffered from a number of bugs and was limited by bad weather, and the team was finally withdrawn. However, the GNAT 750 continued to be built, leading to an "Improved GNAT" or "I-GNAT" variant, with a turbocharged engine and general overall refinements to increase reliability, reduce maintenance, and enhance capability. The GNAT 750 also led to a next-generation derivative, the "GNAT 750-45", much better known as the Predator.
