The missile of Barak SAM system is designed to replace or complement gun-based CIWS platforms, such as the Phalanx CIWS, with a more flexible and longer-range SAM. The missiles are mounted in an eight cell container (which requires little maintenance) and are launched straight up. The launcher of Barak SAM system utilizes a compact vertical launching system, with an 8-cell module weighing 1,700 kg. Fire control is provided by an equally compact C3I system that weighs 1,300 kg, which can either operate independently or in conjunction with other onboard sensors. The radar system of C3I provides 360 degree coverage and the missiles can take down an incoming missile as close as 500 meters away from the ship.
    Note : Recently, India & Israel jointly developed most advanced long range surface to air missile Barak-8 was successfully test fired off the Odisha cost. Reports suggest the missile has been increased to a maximum range of 90 km following “range upgrade discussions” between India and Israel during November 2014. Barak 8 was jointly developed by Israel Aerospace Industries (IAI), India’s Defence Research & Development Organization (DRDO), Israel’s Administration for the Development of Weapons and Technological Infrastructure, Elta Systems, Rafael and other companies. Bharat Dynamics Limited (BDL) produces the missiles.

    7. Which of the following is a stealth aircraft virtually undetectable even by radar?

    (1) B-2 Spirit
    (2) B1-B Lancer
    (3) B-52 Stratofortrees
    (4) FA-18 Homets
    Answer:
    7. (3) The Boeing B-52 Stratofortress is a long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, who have continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber carries up to 32,000 kg of weapons. Due to the late 1950s-era threat of surface-to-air missiles (SAMs) that could threaten high-altitude aircraft, seen in practice in the 1960 U-2 incident, the intended use of B-52 was changed to serve as a low-level penetration bomber during a foreseen attack upon the Soviet Union, as terrain
    masking provided an effective method of avoiding radar and thus the threat of the SAMs. Although never intended for the low level role, the B-52’s flexibility allowed it to outlast several intended successors as the nature of aerial warfare changed.

    8. Who developed Ballistic Missile?

    (1) Wernher von Braun

In his 20s and early 30s, von Braun was the central figure in Germany’s rocket development program, responsible for the design and realization of the V-2 combat rocket during World War II. After the war, he and some select members of his rocket team were taken to the United States as part of the then-secret Operation Paperclip. Von Braun worked on the United States Army intermediate range ballistic missile (IRBM) program before his group was assimilated by NASA. Under NASA, he served as director of the newly formed Marshall Space Flight Center and as the chief architect of the Saturn V launch vehicle, the super-booster that propelled the Apollo spacecraft to the Moon.

    9. Who developed Ballistic Missile?

    (1) Wernher Von Braun
    (2) J. Robert Oppenheimer
    (3) Edward Teller
    (4) Samuel Cohen
    Answer:
    9. (1) A ballistic missile is a missile that follows a suborbital ballistic flight path with the objective of
    delivering one or more warheads to a predetermined target. To date, ballistic missiles have been propelled during powered flight by chemical rocket engines of various types. The first ballistic missile was the A-4, commonly known as the V-2 rocket, developed by Nazi Germany in the 1930s and 1940s under direction of Wernher von Braun. The first successful launch of a V-2 was on October 3, 1942 and began operation on September 6, 1944 against Paris, followed by an attack on London two days later. By the end of World War II, May 1945, over 3,000 V-2s had been launched.

    10. Geo–stationary satellite revolves at–

    (1) any height
    (2) fixed height
    (3) height which depends upon its mass
    (4) height above pole
    Answer:
    10. (2) A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same
    as the Earth’s rotation period. Such a satellite returns to the same position in the sky after each sidereal
    day, and over the course of a day traces out a path in the sky that is typically some form of analemma.
    Geosynchronous satellites have the advantage of remaining permanently in the same area of the sky,
    as viewed from a particular location on Earth, and so permanently within view of a given ground station. Geostationary satellites have the special property of remaining permanently fixed in exactly the same position in the sky, meaning that ground-based antennas do not need to track them but can remain fixed in one direction.

    (1) Its time period is 24 hrs
    (2) Its angular speed is equal to that of earth about its own axis
    (3) It is fixed in space
    (4) It revolves from west to east over the equator
    Answer:
    17. (3) A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same
    as the Earth’s rotation period. Such a satellite returns to the same position in the sky after each sidereal
    day, and over the course of a day traces out a path in the sky that is typically some form of analemma. A geostationary orbit, or Geostationary Earth Orbit (GEO), is a circular orbit 35,786 kilometres above
    the Earth’s equator and following the direction of the Earth’s rotation. An object in such an orbit has an
    orbital period equal to the Earth’s rotational period (one sidereal day), and thus appears motionless, at a
    fixed position in the sky, to ground observers.
