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 Block 4 KH-11 reconnaissance satellite, and the last official 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.
In 2020, MIT Technology Review reported that USA-245 was likely being "stalked" by a Russian satellite, Kosmos 2542, in a possible attempt to spy on US-245 to deduce its camera aperture and resolution, or its computer functionality and operating times.
On January 20, something rather strange happened in orbit. A Russian satellite suddenly maneuvered itself so that it was closely shadowing a US spy satellite. The pair are now less than 186 miles (300 kilometers) apart—a short distance when it comes to space. While we don’t know for sure what’s going on, the Russian satellite’s actions strongly suggest it is there to spy on the US one—and there is very little the US can do about it.
