The US Department of Defense intends to provide Singapore with $500 million-worth of logistics support for four Boeing KC-135As being modernised into the KC-135R tanker configuration. It says that Singapore needs this logistics support to ensure that the KC-135R tanker programme announced in April will provide Lockheed Martin F-16 in-flight refuelling. The work will be performed by Boeing together with CFM International, which provides the CFM-56 turbofan which powers the existing four-engine KC-135R.
