USA-245 or NRO Launch 65 (NROL-65) is an American reconnaissance satellite which is operated by the National Reconnaissance Office. Launched in August 2013, it is the last KH-11 reconnaissance satellite, and the last spacecraft to be launched in the Keyhole program.
Details of USA-245's mission are classified by the US military, however numerous independent analysts identified it as a KH-11 before launch, and amateur satellite watchers have since observed it in the orbit used by such satellites. KH-11 satellites are used to provide high-resolution optical and infrared imagery for US intelligence agencies.
USA-245 was launched by United Launch Alliance, using a Delta IV Heavy rocket with the flight number Delta 364 and the name Victoria. The launch took place from Space Launch Complex 6 at the Vandenberg Air Force Base at 18:03 UTC (11:03 local time) on 28 August 2013. After deploying its payload, the rocket's upper stage was deorbited after completing one orbit. The launch was the first Delta IV mission to use a new ignition sequence aimed at reducing damage to the first stage insulation caused by igniting a cloud of hydrogen around the vehicle at liftoff. To mitigate this, the rocket's starboard engine was lit two seconds earlier than on previous flights.
