Question 1 of 5
1. Question
Consider the following statements about Next Generation Missile Vessels (NGMV)
- Six NGMVs are being built by Cochin Shipyard Limited (CSL)
- The primary role of the ships would be to provide offensive capability against enemy warships.
- The core of the NGMV propulsion system is the LM2500, a marine gas turbine.
How many of the statements given above are correct?
Correct
Solution (c)
Statement Analysis
Statement 1 Statement 2 Statement 3 Correct Correct Correct · The NGMVs would be heavily armed war vessels incorporating stealth, high speed, and offensive capability being built for the Indian Navy. · Six NGMVs are being built by government-run Cochin Shipyard Limited (CSL) at a cost of Rs 9,805 crore.
· The delivery of ships is scheduled to commence from March 2027.
· The primary role of the ships would be to provide offensive capability against enemy warships, merchantmen, and land targets. · These ships will be capable of conducting Maritime Strike Operations and Anti Surface Warfare Operations and would be a potent instrument of sea denial for enemy ships, especially at choke points.
· In a defensive role, these ships would be employed for Local Naval Defence operations and seaward defence of Offshore Development Area.
Features: · The core of the NGMV propulsion system is the LM2500, a marine gas turbine, manufactured by the American engine manufacturer General Electric. LM2500 is engineered to unleash superior power while meeting stealth requirements.
· With a top speed of 35 knots (64 kmph), these vessels carry an array of anti-surface weapons.
· The CSL will equip the vessels with loitering munitions, unmanned vehicles, and other guided weapons to add to its firepower.
· The NGMVs’ primary weapon is anticipated to be the BrahMos supersonic cruise missile, capable of striking targets at long ranges.
Context: American engine manufacturer General Electric recently announced that its LM2500 marine engines have been chosen to power Indian Navy’s Next Generation Missile Vessels (NGMV).

Question 3 of 5
3. Question
Consider the following statements about Long-billed Vulture
- These are native to India, Pakistan, and Nepal.
- Their preferred habitat savannas and open places near cultivated areas.
- Their conservation status in IUCN Red List is Endangered.
How many of the statements given above are correct?
Correct
Solution (b)
Statement Analysis
Statement 1 Statement 2 Statement 3 Correct Correct Incorrect · It is an old World vulture native to the Asian region. · They are also known as Indian long-billed vultures due to their comparatively longer beak.
· It is a medium-sized and bulky scavenger feeding mostly on the carcasses of dead animals.
· Females of this species are smaller than males.
· Habitat: They are usually found in savannas and other open habitats around villages, cities, and near cultivated areas.
· Distribution: These are native to India, Pakistan, and Nepal.
Conservation status
· IUCN Red List: Critically Endangered
· Threats: The Indian vulture has suffered a 97-99% population decrease due to poisoning caused by the veterinary drug diclofenac. This drug is toxic for vultures; it was given to working animals as it reduced joint pain and so kept them working for longer.
Context: A study published recently has highlighted that the population of the critically endangered long-billed vulture has seen a steady increase between 2015 and 2021, with the species exhibiting a 74% breeding success rate in the Mudumalai Tiger Reserve (MTR).

Question 4 of 5
4. Question
Consider the following statements about Trojan asteroids
- These are a class of asteroids that occupy a stable Lagrange Point in a planet’s orbit around the sun.
- These are found around Lagrange Point L4 or L5 points which make them gravitationally stable.
Choose the correct statements:
Correct
Solution (c)
Statement Analysis
Statement 1 Statement 2 Correct Correct Trojan asteroids: · Trojan asteroids are a class of asteroids that occupy a stable Lagrange Point in a planet’s orbit around the sun.
· These are usually found around Lagrange PointL4 or L5 points which makes them gravitationally stable.
· These are thought to be remnants of the primordial material that formed the outer planets.
· Their orbit around the sun is similar to the orbit of the planet they are associated with.
· These were discovered by German astrophotographer Max Wolf in 1906, but they were named so later.
· They have unusual orbits, remain gravitationally stable for long periods of time and studying them can provide useful insights into the evolution of the solar system.
What are Lagrange points?
· A Lagrange point is a position in space where the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them.
· These points in space can be used by spacecraft to reduce fuel consumption needed to remain in position.
· The Lagrange points are named in honour of Italian-French mathematician Josephy-Louis Lagrange, and there are five of them: L1, L2, L3, L4, and L5.
· The L1 point of the Earth-Sun system affords an uninterrupted view of the Sun.
· It is currently home to the Solar and Heliospheric Observatory Satellite SOHO.
Context: Scientists have finally discovered a Trojan asteroid for Saturn, thereby establishing the presence of these celestial bodies alongside all giant planets in our solar system.
