Missile - Current Affairs Questions and Answers

1)   Which country has been issued sanctions by the US over its ballistic missile program in July 2017?

a. Iran
b. Iraq
c. Saudi Arabia
d. North Korea
Answer  Explanation 

ANSWER: Iran

Explanation:
The Trump administration on 18th July 2017 unveiled new economic sanctions against Iran over its ballistic missile program and for contributing to regional tensions.

This comes one day after warning Tehran that it was not following the spirit of its nuclear agreement with world powers.

The US Department of Treasury, in a statement, said it was targeting 16 entities and individuals for supporting what is said was “illicit Iranian actors or transnational criminal activity.”

Those sanctioned had backed Iran’s military or Iran’s Islamic Revolutionary Guard Corps (IRGC) by developing drones and military equipment, producing and maintaining boats, and procuring electronic components, the U.S. said.

Others have also ‘orchestrated the theft of US and Western software programs’ sold to Iran’s government, the Treasury Department said.

The US State Department had also designated two Iranian organizations involved in Iran’s ballistic missile program, according to the Treasury Department.

2015 Nuclear Deal: Know More

  • The 2015 Nuclear Deal was a preliminary framework agreement signed between Iran and P5+1 countries (United States, United Kingdom, Russia, France, China- plus Germany) and the European Union in July 2015.
  • The deal is also called as Joint Comprehensive Plan of Action (JCPA) or Vienna agreement.
  • The deal aims to stop Iran from acquiring a nuclear weapon in return for lifting international oil and financial sanctions.
  • Under it, Iran has agreed to give up its most advanced centrifuges and use only its oldest models.
  • But it still allows Iran to continue enrichment in lower quantities for civilian purposes such as power plants. As part of the deal Iran has agreed to reduce its stockpile of uranium by 98%.
  • Under this deal, Iran could keep 300 kg enriched uranium for the next 15 years and it will get rid of extra uranium by shipping it to Russia.

4)   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.


5)   US is setting up which missile defence system in South Korea ?

a. THAAD
b. TMAAD
c. TCAAD
d. None of the above
Answer  Explanation 

ANSWER: THAAD

Explanation:
US missile launchers and other equipment needed to set up a controversial missile defence system have arrived in South Korea, the US and South Korean militaries said on March 7, 2017.

This is a day after North Korea test-launched four ballistic missiles into the ocean near Japan.

The plans to deploy the Terminal High-Altitude Area defence system, or THAAD, by the end of this year have angered not only North Korea, but also China and Russia, which see the system's powerful radars as a security threat.

The system is defensive and not meant to be a threat to Beijing or Moscow.

The US military said in a statement that THAAD is meant to intercept and destroy short and medium range ballistic missiles during the last part of their flights.

Some South Korean liberal presidential candidates have said that the security benefits of having THAAD would be curtailed by worsened relations with neighbours China and Russia.

China's condemnation of South Korean plans to deploy THAAD has triggered protests against South Korean retail giant, Lotte, which agreed to provide one of its golf courses in southern South Korea as the site of THAAD.

The South Korean government also raised worries about a reported ban on Chinese tour groups visiting the country.

North Korea recently fired four ballistic missiles in an apparent protest against ongoing US-South Korean military drills that it views as an invasion rehearsal.

The missiles flew about 1,000 kilometres (620 miles) on average, three of them landing in waters that Japan claims as its exclusive economic zone


6)   US and which country conducted successful missile tests in Feb 2017?

a. Japan
b. India
c. China
d. South Korea
Answer  Explanation 

ANSWER: Japan

Explanation:
The United States and Japan successfully concluded a flight test of a Standard Missile-3 (SM-3) Block IIA off the west coast of Hawaii on February 3, the U.S. Missile Defence Agency (MDA) announced recently.

According to the MDA, a next-generation SM-3, launched from a US warship, destroyed an incoming ballistic missile target.

A medium-range ballistic missile target was launched from the Pacific Missile Range Facility at Kauai, Hawaii.

The Arleigh Burke-class guided missile destroyer USS John Paul Jones “detected and tracked the target missile with its onboard AN/SPY-1D(V) radar using the Aegis Baseline 9.C2 weapon system. Upon acquiring and tracking the target, the ship launched an SM-3 Block IIA guided missile which intercepted the target.”

This was the third flight test and the first intercept test of a SM-3 Block IIA, the most advanced version of the SM-3 “hit-to-kill” interceptor.

The missile interceptor is designed to destroy short- to intermediate-range ballistic missile threats and can be deployed at land-based Aegis Ashore sites and Aegis-equipped warships.

The latest of different variants of the SM-3 features a larger rocket motor and a larger kinetic warhead.


7)   North Korea has fired a ballistic missile into which sea in Feb 2017?

a. Japan Sea
b. South China Sea
c. Red Sea
d. Caspian Sea
Answer  Explanation 

ANSWER: Japan Sea

Explanation:
North Korea fired a ballistic missile into the sea early on 12th February 2017.

This is the first such test since U.S. President Donald Trump was elected, and his administration indicated that Washington would have a calibrated response to avoid escalating tensions.

The test was likely to have been of an intermediate-range Musudan-class missile that landed in the Sea of Japan, according to South Korea’s military.

The launch marks the first test of Trump’s vow to get tough on an isolated North Korean regime that last year tested nuclear devices and ballistic missiles at an unprecedented rate in violation of United Nations resolutions.

The latest test comes a day after Trump held a summit meeting with Japanese Prime Minister Shinzo Abe.

Abe called the launch “absolutely intolerable” and said North Korea must comply with UN Security Council resolutions.

China is North Korea’s main ally but has been frustrated by Pyongyang's repeated provocations,.

It also bristles at pressure from Washington and Seoul to curb the North and its young leader, Kim Jong Un.

China’s Foreign Ministry did not immediately respond to a request for comment.

Mr. Trump and his aides are likely to weigh a series of possible responses, including new U.S. sanctions to tighten financial control.

There may also be an increase in naval and air assets in and around the Korean peninsula and accelerated installation of new missile defence systems in South Korea, the administration official said.

Trump has pledged a more assertive approach to North Korea but given no clear sign of how his policy would differ from Obama’s so-called strategic patience.

This is part of a show of force in response to the new U.S. administration’s hard-line position against the North.

A South Korean military source said the missile reached an altitude of about 550 km.

While Seoul initially said the missile was probably a medium-range Rodong, it later said the launch was likely of a Musudan, which is designed to fly up to 3,000-4,000 km.

The North attempted eight Musudan launches last year.

Only one of those launches - of a missile that flew 400 km in June - was considered a success by officials and experts in South Korea and the United States.

Once fully developed, a North Korean ICBM could threaten the continental United States, which is about 9,000 km from North Korea.


8)   On 11th Feb, 2017, India tested the BMD related missile which stands for ______

a. Ballistic missile defence
b. Ballistic missile interceptor defence
c. Ballistic missile detector
d. None of the above
Answer  Explanation 

ANSWER: Ballistic missile defence

Explanation:
India took a big step towards an operational two-tier ballistic missile defence (BMD) system by testing a high-altitude interceptor missile to destroy an incoming ballistic missile over the Bay of Bengal on 11th Feb 2017.

This missile can destroy an enemy missile high in the sky. Only four to five countries in the world have done this.

The Defence Research and Development Organisation was itself gung-ho about its long-delayed BMD system, claiming it would now be possible to deploy the two-layered missile shield to protect a city or strategic installation in two years.

But it had earlier also promised that New Delhi would get the missile shield, capable of tackling hostile missiles with a 2,000-km strike range, by 2014 at the latest.

Scientists, however, say they are confident of achieving the target this time.

The "exo-atmospheric" interceptor missile tested on 11th Feb 2017, also called the PDV (Prithvi defence vehicle), after all, directly hit the target missile at an altitude of 97 km.

The test began at 7.45 am with the two-stage target missile, replicating an enemy ballistic missile, being launched from a ship in the Bay of Bengal.

In the fully-automated operation, with long-range radars continuously tracking the target and feeding data about its trajectory to the mission computers, the interceptor missile was then fired from the Abdul Kalam Island (Wheeler Island) off Odisha coast around 200-km away.

India has crossed an important milestone in building its overall capability towards enhanced security against incoming ballistic missile threats.

It has entered an exclusive club of four nations (US, Russia, China and Israel) by developing capabilities to secure its skies and cities against hostile threats.

DRDO's experimental two-tier system is designed to track and destroy ballistic missiles both inside (endo) and outside (exo) the earth's atmosphere.

The third layer, in turn, is planned to tackle low-flying cruise missiles, artillery projectiles and rockets in the line with the overall aim to achieve near 100% kill or interception probability'.

Phase-I of the BMD system, with interceptors flying at 4.5 Mach high-supersonic speeds to intercept enemy missiles, is meant to tackle hostile missiles with a 2,000-km strike range.

Phase-II will be geared for taking on 5,000-km range missiles, with interceptors at hypersonic speeds of 6-7 Mach.

BMD Systems: Know More

  • BMD systems are highly complex to develop and deploy.
  • They require an overlapping network of early-warning and tracking sensors.
  • They also need reliable command and control posts, land and sea-based batteries of advanced interceptor missiles.
  • BMD systems also cannot ensure 100% destruction of all incoming hostile missiles.


9)   China has tested which missile with 10 nuclear warheads?

a. DF-6C
b. DF-7C
c. DF-8C
d. None of the above
Answer  Explanation 

ANSWER: None of the above

Explanation:
China has tested a new version of a missile that can carry up to 10 nuclear warheads.

This is signalling a major shift in its nuclear capability as Beijing gears up for a possible military showdown with the US under Trump Presidency.

The flight test of the DF-5C missile was carried out last month using 10 multiple independently targetable reentry vehicles, or MIRVs.

The test of the inert warheads was monitored closely by U.S. intelligence agencies.

The DF-5 is a two-stage, liquid-fueled missile with a range of around 8,000 miles.

The missile was fired from the Taiyuan Space Launch Center in central China and flew to an impact range in the western Chinese desert.

The test of a missile with 10 warheads is significant because it indicates the secretive Chinese military is increasing the number of warheads in its arsenal, the website reported.

Estimates of China's nuclear arsenal for decades put the number of strategic warheads at the relatively low level of around 250 warheads.

U.S. intelligence agencies in February reported that China had begun adding warheads to older DF-5 missiles, in a move that has raised concerns for strategic war planners.

Uploading Chinese missiles from single or triple warhead configurations to up to 10 warheads means the number of warheads stockpiled is orders of magnitude larger than the 250 estimate.

Currently, U.S. nuclear forces - land-based and sea-based nuclear missiles and bombers - have been configured to deter Russia's growing nuclear forces and the smaller Chinese nuclear force.

Under the 2010 U.S.-Russian arms treaty, the United States is slated to reduce its nuclear arsenal to 1,550 deployed warheads.

A boost in the Chinese nuclear arsenal to 800 or 1,000 warheads likely would prompt the Pentagon to increase the U.S. nuclear warhead arsenal by taking weapons out of storage.
