An intercontinental ballistic missile (ICBM) is a guided ballistic missile with a minimum range of 5500 km primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads).
 Similarly, conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs.
 Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target.
The V-2 (German: "Vergeltungswaffe 2" , "Retribution Weapon 2"), technical name Aggregat 4 (A4), was the world's first long-range guided ballistic missile.
 The missile with a liquid-propellant rocket engine was developed during the Second World War in Germany as a "vengeance weapon", assigned to attack Allied cities as retaliation for the Allied bombings against German cities.
 The V-2 rocket also became the first artificial object to travel into outer space by crossing the Kármán line with the vertical launch of MW 18014 on 20 June 1944.
Swordfish is an Indian active electronically scanned array (AESA) long-range tracking radar specifically developed to counter ballistic missile threat.
 It will be a part of the Indian Ballistic Missile Defence Programme.
 First testing of this radar was in March 2009.
 Main aim of the test was to validate the capabilities of the "Swordfish" Long Range Tracking Radar (LRTR).
 "The missile to be hit will be fired from a longer distance than it was in the earlier test.
 DRDO tested whether the radar could track the incoming missile from that distance or not," said a member of the project.This radar is an acknowledged derivative of the Israeli Green Pine long range radar, which is the critical component of that country's Arrow missile defence system.
 However, it differs from the Israeli system as it employs Indian Transmit Receive modules, signal processing, computers and power supplies.
 It is also more powerful than the base Green Pine system and was developed to meet India's specific BMD needs.
David Starr, Space Ranger is the first novel in the "Lucky Starr" series, six juvenile science fiction novels by Isaac Asimov that originally appeared under the pseudonym Paul French.
 The novel was written between 10 June and 29 July 1951 and first published by Doubleday & Company in January 1952.
 Since 1971, reprints have included an introduction by Asimov explaining that advancing knowledge of conditions on Mars have rendered some of the novel's descriptions of that world inaccurate.
 The novel was originally intended to serve as the basis for a television series, a science-fictionalized version of "The Lone Ranger", but the series was never made, in part because another series called "Rocky Jones, Space Ranger" was already in the planning stages.
The Shaheen-II (Urdu:شاهين–اا; codename: Hatf–VI Shaheen) is a land-based supersonic surface-to-surface medium-range guided ballistic missile.
 The "Shaheen-II" is designed and developed by the NESCOM and the National Defence Complex (NDC) of Pakistan.
 The Shaheen missile series is named after a falcon that lives in the mountains of Pakistan.
 The missile is considered to be Pakistan's equivalent to the US Pershing II.
 It is suspected to be a derivative of Chinese M-18 missile, a two-stage missile based on the M-9.
A ballistic missile is a missile that follows a ballistic trajectory with the objective of delivering one or more warheads to a predetermined target.
 A ballistic missile is only guided during relatively brief periods of flight (there are unguided ballistic missiles as well, such as 9K52 Luna-M, although these may well be considered rockets), and most of its trajectory is unpowered and governed by gravity and air resistance if in the atmosphere.
 This contrasts to a cruise missile, which is aerodynamically guided in powered flight.
 Long range intercontinental ballistic missiles (ICBM) are launched on a sub-orbital flight trajectory and spend most of their flight out of the atmosphere.
 Shorter range ballistic missiles stay within the Earth's atmosphere.
An intermediate-range ballistic missile (IRBM) is a ballistic missile with a range of 3,000–5,500 km (1,864–3,418 miles), between a medium-range ballistic missile (MRBM) and an intercontinental ballistic missile (ICBM).
 Classifying ballistic missiles by range is done mostly for convenience; in principle there is very little difference between a low-performance ICBM and a high-performance IRBM, because decreasing payload mass can increase range over ICBM threshold.
 The range definition used here is used within the U.S. Missile Defense Agency.
 Some other sources include an additional category, the long-range ballistic missile (LRBM), to describe missiles with a range between IRBMs and true ICBMs.
 The more modern term theater ballistic missile encompasses MRBMs and SRBMs, including any ballistic missile with a range under 3500 km .
Agni-II (Sanskrit: अग्नि "fire"), is a strategic ballistic missile.
 The Agni (missile) family is envisaged to be the mainstay of the Indian missile-based strategic nuclear deterrence.
 The Agni-II is a medium-range ballistic missile (MRBM) with two solid fuel stages and a Post Boost Vehicle (PBV) integrated into the missile's Re-entry Vehicle (RV).
 The Agni's manoeuvring RV is made of a carbon-carbon composite material that is light and able to sustain high thermal stresses of re-entry, in a variety of trajectories.
 The Agni-IIA is a more advanced version of Agni-II, albeit with more sophisticated and lighter materials, yielding a better range and operating regime.
 Agni-IIA was later renamed as Agni-IV plugging the gap between Agni-II and Agni-III.
 While the first test of Agni-IV in December 2010 was a failure, the second test flight in November 2011 was a success Agni-II, developed as part of medium- and long-range Agni series of missile systems, has already been inducted into the Armed Forces.
Manhunt in Space is a 75-minute 1954 American science fiction film, consisting of three consecutive episodes of the TV series "Rocky Jones, Space Ranger", which told a continuous story.
 It was released only on 16mm for home movie rental and television syndication.
 It was directed by Hollingsworth Morse.
 The film is now in the public domain.
 It appeared as an episode of the American television comedy series "Mystery Science Theater 3000" in 1992.
The Orbit Jet was a fictional spaceship in the 1954 TV series "Rocky Jones, Space Ranger".
 It strongly resembled a V-2 rocket in overall form, with a very prominent exhaust plume when flying, but had wings in addition to tailfins (even its radio callsign, "XV-2" relates it to that seminal World War II design).
 There were references in the dialog to the engines being "atomic".
 The "Orbit Jet" had a crew of two (pilot and copilot), but often had three or four others on board depending on the mission and destination.
 It often flew from Earth to inhabited moons of Jupiter and Saturn, which it seemed to reach in hours or days of time within the story.
