The Brazilian Air Force (FAB) retired its KC-137 tanker/transport aircraft on Thursday October 10th, 2013.
The military version of the Boeing 707 served with the FAB for 27 years. Four ex-Varig 707s were converted to KC-137 by Boeing in 1986 and 1987 and given the serials FAB-2401, -2402, -2403 and -2404. The fleet flew with No. 2 Group, or Segundo Grupo de Transporte (2º/2º GT) from Do Galeão Airbase/Antônio Carlos Jobim IAP near Rio de Janeiro. 2401 was the official Brazilian presidential ride until the Airbus VC1A arrived in 2005.
The KC-137s could transfer 1700 litres per minute to the FAB’s Northrop F-5EMs, Embraer A-1Ms and Mirage 2000-F, up to 90,000 litres in total during a mission.
