The resolution of the KH-11 satellite equipment of the latest modification is about 15 cm.
The United States successfully launched a Delta IV Heavy launch vehicle, launching the secret NROL-91 satellite into orbit in the interests of the US National Space Intelligence Agency. This was announced by the United Launch Alliance (ULA) on Sunday evening, September 25th.
The launch took place from Vandenberg Air Force Base in California. This makes 153 for ULA, which is a joint venture between Boeing and Lockheed Martin. All launches are 100% successful.
Information about the satellite is classified. But according to the available data, another reconnaissance satellite of the KH-11 Key Hole type (Keyhole) with optoelectronic equipment was launched in an elliptical orbit. The bus-sized, 1.9-tonne satellite’s mission is to transmit real-time, ultra-high-resolution images to the US intelligence community.
The resolution of the KH-11 satellite equipment of the latest modification is about 15 cm. Its main mirror has a diameter of 2.4 meters – similar to that of the American Hubble space telescope, previously created by Lockheed Martin based on the KH reconnaissance satellite -labingisa. In size, it also resembles Hubble and is 19.5 meters long, with a diameter of about 3 meters.
Today the American orbital constellation has six heavy satellites of the KH-11 type. The cost of each device is about $2 billion.
