Indian Defence and Strategic Weapons

India received its first AWACS (Airborne Warning and Control System) aircraft from Israel in 2009. The contract included three such aircraft, so after the first delivery, two more remained to be delivered. The Phalcon AWACS systems are mounted on IL-76 aircraft and provide India with significant airborne radar and surveillance capabilities.

After the 2008 Mumbai attacks, TATA proposed developing a specialized tactical suit for commandos to enhance their protection and operational capability. This was part of broader modernization efforts. RAW (Research and Analysis Wing) is an intelligence agency, not a defense contractor. BHEL is in power equipment. HAL makes aircraft, not personal armor.

The M-16 is not used by the Indian Army. The Indian Army uses the INSAS rifle series (indigenous), has acquired AK-203/AKM variants, and uses various other weapons. The MP5 submachine gun is used by special forces. The M-16 is primarily used by US and allied forces, not the Indian military. India has gone with Russian AK variants and indigenous INSAS instead of the American M-16 platform.

FOAB (Father of All Bombs) is a Russian thermobaric weapon tested in 2007, claimed to be the most powerful non-nuclear weapon ever developed, with a yield equivalent to 44 tons of TNT. MOAB (Mother of All Bombs) is the American counterpart with approximately 11 tons yield. Tomahawk is a cruise missile and Patriot is a surface-to-air missile system - both are far less powerful.

The SR-71 Blackbird is indeed the fastest operational aircraft ever built, capable of sustained speeds above Mach 3 (approximately 2,200 mph). However, it was a strategic reconnaissance aircraft, not a fighter aircraft. Among actual fighter aircraft, the MiG-25 holds the speed record. The question misclassifies the SR-71 but the speed claim is correct.

F-117 Nighthawk and B-2 Spirit are dedicated stealth aircraft designed with radar-absorbing materials and faceted shapes to minimize radar detection. SU-47 Berkut is a Russian technology demonstrator with forward-swept wings that has some reduced radar cross-section features. SU-37 is an upgraded Su-35 Flanker fighter with no stealth characteristics - it's a conventional air-superiority fighter focused on maneuverability and thrust vectoring, making it the only clear non-stealth option among the choices.

Operation Shakti (1998) was India's series of nuclear tests at Pokhran, codenamed after the powerful Hindu concept of divine feminine energy. The tests consisted of five detonations (Shakti I through Shakti V), making 'Shakti' the correct umbrella designation. Option B correctly identifies this as India's nuclear project. 'Widhwans' and 'Vijay' are not related to India's nuclear program.

INS Arihant is India's first indigenously built nuclear-powered submarine, commissioned in 2016 as part of the Arihant-class. The other options - INS Shalki, INS Sindhuvir, and INS Vagli - are all diesel-electric submarines of the Indian Navy's Sindhughosh and Shishumar classes.

INS Rajput is a guided-missile destroyer of the Indian Navy, commissioned in 1980 as part of the Rajput-class. INS Shivalik (Option C) is a stealth frigate, INS Kirch (Option D) is a corvette, and INS Shankul (Option A) is also a corvette. Destroyers are larger, more heavily armed warships designed for fleet defense and anti-submarine warfare.

Sachin Tendulkar was honoured as a Group Captain by the Indian Air Force (IAF) in 2010. He was awarded the honorary rank of Group Captain, making him the first sportsperson to receive such an honour from the IAF. This recognition was for his contribution to cricket and as a role model for youth.
