UAS groups of the United States military. The U.S. Department of Defense (DoD) classifies unmanned aerial systems (UAS) into "Groups" according to their size and capability, a joint system that replaced the service branches' separate categorization schemes in 2011. [1][2][3] The "Group" system has five categories, whose capabilities increase ...
Lockheed was chosen to build the reconnaissance plane and in August 1955 the first Lockheed U-2 was test-flown. The U-2 was chosen as the plane to use because of its operational flexibility, amazing aerodynamic design, and adaptable airframe. With all of the pros of the plane, the U-2 would make a great number of trips over the Soviet Union. [7]
This result has been further improved to 2 126.0 for AES-128, 2 189.9 for AES-192 and 2 254.3 for AES-256, [27] which are the current best results in key recovery attack against AES. This is a very small gain, as a 126-bit key (instead of 128 bits) would still take billions of years to brute force on current and foreseeable hardware.
Grumman E-1 Tracer. The Grumman S-2 Tracker (S2F prior to 1962) was the first purpose-built, single airframe anti-submarine warfare (ASW) aircraft to enter service with the United States Navy. Designed and initially built by Grumman, the Tracker was of conventional design — propeller-driven with twin radial engines, a high wing that could be ...
Lockheed U-2. The Lockheed U-2, nicknamed " Dragon Lady ", is an American single-engine, high altitude reconnaissance aircraft operated from the 1950s by the United States Air Force (USAF) and the Central Intelligence Agency (CIA). It provides day and night, high-altitude (70,000 feet, 21,300 meters), all-weather intelligence gathering.
The Advanced Synthetic Aperture Radar System-2 (ASARS-2) is the radar system mounted on some variants of the Lockheed U-2 reconnaissance aircraft. The ASARS-2 radar was originally developed in the early 1980s by Hughes Aircraft, which was acquired by Raytheon in the late 1990s. It is capable of detecting and accurately locating both stationary ...
