K-13/R-3 (Object 300) (AA-2 Atoll): It was the standard variant and entered limited service only two years later in 1960. K-13A/R-3S (Object 310) (AA-2A Atoll): This entered service in 1962. The R-3S was the first version to enter widespread production, in spite of a very long seeker settling time around 22 seconds, as opposed to 11 seconds for ...
By 5 June 2011 astronauts had made over 159 EVAs to add components to the station, totaling more than 1,000 hours in space. [87] [88] Zarya and Unity, the first two modules of the ISS, pictured in May 2000. The foundation for the ISS was laid with the launch of the Russian-built Zarya module atop a Proton rocket on 20 November 1998.
The type of guidance depends on the type of target. Ships, for example, may be detected via passive radar or active radar homing, which is less effective against multiple, small, fast-moving land targets. There is some cross-over between air-to-surface missiles and surface-to-surface missiles.
In addition to carrying more smart bombs, moving them internally from the wings reduces drag and achieves a 15 percent reduction in fuel consumption. [83] The US Air Force Research Lab is investigating defensive laser weapons for the B-52. [84] The B-52 is due to receive a range of upgrades alongside a planned engine retrofit.

For the living space he used the same Modulor concept for measuring the ideal living space that he had used in the Unité d'Habitation in Marseille; height under the ceiling of 2.26 metres (7 feet 5 inches); and width 1.83 metres (6 feet 0 inches). [69] Le Corbusier used raw concrete to construct the convent, which is placed on the side of a hill.
In mathematical analysis, the Dirac delta function (or δ distribution), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one.
The cere is yellow, as are the feet, and the beak and claws are black. [25] The upper beak is notched near the tip, an adaptation which enables falcons to kill prey by severing the spinal column at the neck. [11] [12] [4] An immature bird is much browner, with streaked, rather than barred, underparts, and has a pale bluish cere and orbital ring ...
