The Brazilian Air Force (FAB) on 10 October officially withdrew its Boeing KC-137 transport and refuelling aircraft from active service.
The four original aircraft, operated from Galeão Air Force Base and now all phased out, were former Boeing 707 commercial aircraft converted to military specifications by Boeing and inducted into Brazilian service in 1986 and 1987.
Following an FAB selection announcement in March 2013, contractual negotiations are being carried out with Israel Aerospace Industries (IAI) for the acquisition of two second-hand Boeing 767-300ER commercial airplanes. Those aircraft are to be overhauled and converted into the company's Multi-Mission Tanker and Transport configuration under the FAB's KC-X2 programme for replacing the KC-137.
