3) Which Indian nuclear capable land attack cruise missile was successfully tested with a strike range of 1000 km?
a. Agni
b. Nag
c. Nirbhay
d. Babur
Answer
Explanation
|
ANSWER: Nirbhay
Explanation: India on Nov 7, 2017 successfully flight-tested its indigenous Nirbhay (the fearless) land-attack cruise missile, which can deliver nuclear warheads to a strike range of 1,000-km, after a string of failures since March 2013.
The development is significant because the armed forces have long been demanding nuclear land-attack cruise missiles (LACMs), with ranges over 1,000-km and versatile enough to be fired from land, air and sea.
Often brandished as India's answer to the famed American Tomahawk missiles, as also an effective counter to Pakistan's Babur LACM, the Nirbhay had been in the making for a decade without much success till now.
The sub-sonic missile, designed to carry a 300-kg nuclear warhead, had failed during its first test in March 2013.
Though the second test in October 2014 was a partial success, the third and fourth tests in October 2015 and December 2016 also flopped, leading to talk that the project may have to be scrapped.
The missile has the capability to loiter and cruise at 0.7 Mach, at altitudes as low as 100 m.
The flight test achieved all the mission objectives completely from lift-off till the final splash, boosting the confidence of all scientists associated with the trial.
The guidance, control and navigation system of the missile is configured around the indigenously designed Ring Laser Gyroscope (RLG) and MEMS based Inertial Navigation System (INS) along with GPS system.
The missile majestically cruised for a total time duration of 50 minutes, achieving the range of 647 km.
The fifth test from the Integrated Test Range at Chandipur off Odisha coast, was dubbed a "complete success" by DRDO.
A series of successful tests of this ground-launched version of Nirbhay will pave the way for its induction into the armed forces, though its sea-based variant capable of being fired from nuclear-powered submarines will be the real game-changer.
Difference Between Ballistic and Cruise Missiles - Ballistic missiles like the Agni follow a parabolic trajectory, leaving and re-entering the earth's atmosphere before hitting their targets.
- Cruise missiles like Nirbhay, in turn, are designed to fly at low-altitudes, almost hugging the terrain, to evade enemy radars and missile defence systems.
- Nirbhay has the capability to loiter and cruise at Mach 0.7 at altitudes as low as 100-metre.
- After an initial blast off with a solid-propellant booster rocket engine to gain speed and altitude, Nirbhay deploys its smallish wings and tail fins in the second-stage to thereafter fly like an unmanned aircraft.
- It's designed to be highly manoeuvrable with "loitering capabilities" to first identify and then hit the intended target with precision.
BrahMos: Know More - The supersonic BrahMos missiles, produced jointly with Russia, have already been inducted into the armed forces.
- But the BrahMos, which flies almost three times the speed of sound at Mach 2.8, is meant to carry only conventional warheads and currently has a strike range of only 290-km.
- At least three tests of the extended range (450-km) BrahMos have been conducted after India joined the 34-nation Missile Technology Control Regime (MTCR) in June 2016.
- India, of course, has come a long way in developing nuclear-capable ballistic missiles like the Agni series, which have strike ranges from 700-km to over 5,000-km.

a. Muntra
b. Mundra
c. Mutra
d. Mudra
Answer
Explanation
|
ANSWER: Muntra
Explanation: Government agency Defence Research and Development Organisation (DRDO) has developed India's first unmanned tank that can remotely operate and has named it ‘Muntra’.
The agency has developed the tank in three different variants to tackle any kind of situation- for surveillance, another for mine detection and a third variant for reconnaissance in areas with nuclear and bio threats.
The tank which is a first of its kind in the country has been developed and tested by Combat Vehicles Research and Development Establishment (CVRDE) in Avadi for the army.
The paramilitary has expressed its interest in using them in the areas that have been affected by the Naxals.
Recently two vehicles that have been designed like an armoured tank were recently displayed at the Science for Soldiers exhibition that was organised by DRDO as a tribute to former President APJ Abdul Kalam, who was also known as the Missile Man of India.
During the testing of the vehicle, it was found that its surveillance radar that includes an integrated camera can be used to spy on targets that are 15 km away.
More about the variants of the unmanned tank ‘Muntra’-
Muntra S – This variant has been developed to carry out unmanned surveillance missions.
Muntra M – This variant has been developed for detecting mines.
Muntra N – This variant will be deployed in areas where nuclear radiation or the risk of bio weapons is high.
The tanks have been tested and validated at Mahajan field firing range in Rajasthan.
The Muntra tanks have surveillance radar, an integrated camera along with laser range finder, which can be used to spy on ground target about 15 kilometres away.
Besides heavy weights, the DRDO also showcased a few inventions like a handheld wall penetration radar which if placed on a wall will project on a screen the presence of people inside a building.
DRDO is now working on installing AWAC (Airborne Early Warning and Control System) on an A330 aircraft.
The system is now perfected for use on a smaller Embraer plane.

10) North Korea launched a medium long range missile with _____ capabilities on May 14, 2017.
a. Ballistic
b. Nuclear
c. Long Range
d. Both a and b
Answer
Explanation
|
ANSWER: Both a and b
Explanation: North Korea indicated the missile it launched over the weekend was a new type of “medium long-range” ballistic rocket that can carry a heavy nuclear warhead.
North Korean propaganda must be considered with wariness as Pyongyang has threatened for decades to reduce Seoul to a “sea of fire.”
This missile launch may mark another big advance toward the North’s goal of fielding a nuclear-tipped missile capable of reaching the US mainland.
This launch tested a new type of missile in Pyongyang’s arsenal.
The test is also an immediate challenge to South Korea’s new leader, Moon Jae-in, a liberal elected last week who expressed a desire to reach out to North Korea.
Pyongyang’s aggressive push to boost its weapons program also makes it one of the Trump administration’s most urgent foreign policy worries, though Washington has struggled to settle on a policy.
North Korea’s official Korean Central News Agency called the missile a “new ground-to-ground medium long-range strategic ballistic rocket,” and indicated the “Hwasong-12” was “capable of carrying a large, heavy nuclear warhead.”
The missile flew for half-an-hour and reached an unusually high altitude before landing in the Sea of Japan, the South Korean, Japanese and US militaries said.
The rocket, “newly designed in a Korean-style,” flew 787 kilometers (490 miles) and reached a maximum altitude of 2,111.5 kilometers (1,310 miles).
North Korea “verified the homing feature of the warhead under the worst re-entry situation and accurate performance of detonation system.”
North Korea is not thought to be able yet to make a nuclear warhead small enough to mount on a long-range missile.
