establishment of Newcastle as a regional hub, the terminal facilities were upgraded to handle growing passenger volumes. In 2000, Impulse acquired Boeing 717s and rebranded itself as a low-cost carrier. Newcastle Airport remained an integral part of the Impulse route network until the company was bought out by Qantas the following year. Following Qantas' acquisition of Impulse in 2001, the airport became the maintenance base for Jetstar's Airbus A320 fleet. The base also provides third party aircraft maintenance for the QantasLink's Boeing 717s. In 1997, BAE Systems was awarded the contract for assembly and ongoing system support for the Hawk 127 Lead in Fighters for the RAAF. As part of the contract, a large facility was built adjacent to the passenger terminal at a cost of $15 million. Twenty-one of the thirty three aircraft were assembled at Williamtown, with the final deliveries taking place in October 2001. The BAE facility forms part of the Williamtown Aerospace Centre precinct. In November 2006, a $8.25 million upgrade to the terminal facilities completed. This development doubled the available floor space in the terminal building, enhanced security screening and added a third departure gate, two baggage carousels and a retail concourse with five stores. In the same year, Jetstar Engineering invested $29 million towards improvements to the former Impulse maintenance facilities to allow heavy maintenance on A320 family aircraft to be conducted at the airport, Aeropelican Air Services moved operations to Williamtown from Belmont Airport and Newcastle Airport was named Regional Airport of the Year by the Australian airports industry. Additional car parking and enhanced set down and pick up landside access was added in 2006 at a further cost of $2.7 million. On 24 February 2015, Newcastle Airport's a extension was opened. The new expansion opened the airport to possible international services with a dedicated area for permanent customs, immigration and quarantine facilities. This expansion was the first stage of an $80 million redevelopment, with the existing terminal undergoing a full refurbishment. Redevelopment works for the adjacent RAAF base Williamtown, including a extension of the shared runway, began in January 2015. In February 2022, Bonza announced that the airport would become one of its 17 destinations with the airline planning to fly to the Sunshine Coast and Proserpine from Newcastle.
