Q5882. Which Indian public sector shipyard was responsible for the construction of INS Vikrant?
Explanation
The construction of the INS Vikrant was undertaken by Cochin Shipyard Limited in Kochi, Kerala. This project was the largest and most complex shipbuilding endeavor ever handled by an Indian shipyard. It involved coordinating thousands of components, specialized warship-grade steel, and advanced engineering systems, demonstrating the shipyard’s ability to meet the rigorous standards required for modern naval aviation platforms.
Q5883. Which of the following statements correctly highlights the indigenization achievement of INS Vikrant?
Explanation
INS Vikrant is a testament to India’s "Atmanirbhar Bharat" initiative, with approximately 76% of its components being sourced domestically. This includes the high-grade warship steel produced by the Steel Authority of India and various complex systems like the combat management system. While some specialized components are still imported, the high level of indigenous content signifies a major shift toward self-reliance in strategic naval technology.
Q5884. Identify the correct pair regarding the air wing intended for INS Vikrant.
Explanation
The air wing of INS Vikrant is designed to operate a mix of fighter jets and helicopters. Currently, the Russian-origin MiG-29K serves as the primary multi-role fighter for the carrier. In the future, the navy plans to induct more advanced fighters, possibly including the indigenous Twin Engine Deck Based Fighter or other modern naval aircraft, to enhance the carrier’s strike and defense capabilities.
Q5885. Consider the following statements regarding carrier launch systems:
Statement I: The ski-jump design (STOBAR) is mechanically simpler and cheaper than a catapult system (CATOBAR).
Statement II: A ski-jump allows aircraft to take off with heavier weapon and fuel loads compared to a catapult system.
Which of the following is correct?
Statement I: The ski-jump design (STOBAR) is mechanically simpler and cheaper than a catapult system (CATOBAR).
Statement II: A ski-jump allows aircraft to take off with heavier weapon and fuel loads compared to a catapult system.
Which of the following is correct?
Explanation
The ski-jump system (STOBAR) is mechanically simpler and more cost-effective than catapult-based systems because it does not require complex steam or electromagnetic launch machinery. However, this comes at a performance cost; aircraft taking off from a ski-jump are limited in the amount of fuel and heavy weaponry they can carry compared to those launched with the extra power of a catapult.
Q5886. Which of the following is the most appropriate strategic significance of the commissioning of INS Vikrant for the Indian Navy?
Explanation
The commissioning of INS Vikrant has profound strategic importance as it establishes India as a global naval power with the proven ability to design and build its own aircraft carriers. This capability ensures that India can maintain a strong maritime presence and protect its interests across the Indian Ocean Region. It reduces long-term dependence on foreign shipyards and strengthens the domestic defense industrial base.
Q5887. Identify the odd one out among the systems/ components concerning the indigenous nature of INS Vikrant.
Explanation
While INS Vikrant features a high percentage of indigenous systems, some critical components are sourced from international partners. The warship-grade steel, combat management system, and main gearboxes were all developed or manufactured by Indian companies like SAIL, Tata, and Elecon. The gas turbines used for propulsion, however, are LM2500 models provided by the American company General Electric, representing an imported technology in the ship’s design.
Q5888. Which of the following is an exception regarding countries that have successfully developed and operationalized their own indigenous 5th-generation fighter jets as of 2023?
Explanation
As of 2023, only a few nations have successfully developed and deployed indigenous fifth-generation stealth fighters. This elite group includes the United States with the F-22 and F-35, China with the J-20, and Russia with the Su-57. While India’s AMCA program is an ambitious national project, the aircraft is still in the development and prototyping phase and has not yet been operationalized for active service.
Q5889. Identify the odd one out among the distinct features that separate a 5th-generation fighter (like AMCA) from a 4th-generation fighter (like Mirage 2000).
Explanation
Fifth-generation fighters use advanced design features like serpentine S-duct air intakes to hide engine blades and low-observable shaping to minimize radar reflections. They also feature highly integrated sensor fusion. Standard combat configurations for these jets avoid external tanks or pylons, as these components reflect radar waves and destroy the aircraft’s stealth. Instead, they rely on internal fuel tanks and internal weapons bays for primary missions.
Q5890. What is the primary operational effect of reducing the Radar Cross Section (RCS) of the AMCA?
Explanation
Reducing the Radar Cross Section (RCS) is the primary goal of stealth design. A lower RCS means that the aircraft reflects very little radar energy back to the receiver. Effectively, this allows the AMCA to get much closer to enemy positions or aircraft before it is detected and tracked. This "first look, first shot" advantage is critical for survival and mission success in modern aerial warfare.Answer key for these questions
