Correct Answer :   United States

In a rare announcement, the United States said its ballistic missile submarine, USS West Virginia, visited its Indian Ocean military base at Diego Garcia.

Before it visited the base at Diego Garcia, the submarine had surfaced in the Arabian Sea and participated in a joint, US Strategic Command-directed communications exercise to validate emerging and innovative tactics in the Indian Ocean.
 
About The Submarine :One of the 14 Ohio-class SSBNs in service with the US Navy, the boat is capable of carrying up to 20 Trident II D5 submarine-launched ballistic missiles with multiple, independently targeted warheads. The submarine also conducted a complete crew exchange in Diego Garcia and a subsequent replenishment at sea, highlighting the SSBN force’s readiness and flexibility to remain on patrol for an extended period of time.
 
About Diego Garcia : Diego Garcia is a part of the Chagos Archipelago, which the UK identifies as British Indian Ocean Territory or BIOT. In 1965, the archipelago was separated from Mauritius, then a British colony, and made part of the UK’s overseas territory. Later, the UK evicted the entire population of the archipelago and leased Diego Garcia to the United States for its Indian Ocean military base.
 
What is the Chagos Islands dispute :
 
Mauritius has argued that the Chagos Islands has been a part of its territory since at least the 18th century, till the United Kingdom broke the archipelago away from Mauritius in 1965 and the islands of Aldabra, Farquhar, and Desroches from Seychelles in the region to form British Indian Ocean Territory. 

In June 1976, after Seychelles gained independence from the United Kingdom, the islands of Aldabra, Farquhar, and Desroches were returned by the UK.

The UK declared these islands as an overseas territory in November 1965.

After Mauritius gained independence from the UK in 1968, the United Kingdom refused to return the Chagos Islands to Mauritius claiming in petitions submitted to the Permanent Court of Arbitration that the island was required to “accommodate the United States’ desire to use certain islands in the Indian Ocean for defence purposes”. 

The largest island on the Chagos Islands archipelago, Diego Garcia, is where the US and the UK operate a large military base and was also used as a US military base for the US-led attacks against Afghanistan and Iraq in the 2000s.

For decades there was no litigation concerning the violation of human rights and sovereignty in the Chagos Islands.  

However, in 2015, Mauritius initiated legal proceedings in these matters against the United Kingdom in the Permanent Court of Arbitration at The Hague in the Netherlands.

The UK made several attempts to resist Mauritius’ attempts to take the matter to international court by claiming that the issue was a bilateral matter.
 
India’s Contradictory Stance :
India was among nations to vote in favour of a UN General Assembly resolution that demanded the UK withdraw its “colonial administration” from the Chagos Archipelago unconditionally, supporting Mauritius in its quest for the restoration of sovereignty over the island chain in the Indian Ocean.

However, given the increasing Chinese footprint in the Indian Ocean, India also wants the US to retain its presence in Diego Garcia. New Delhi is believed to have nudged Mauritius to offer to renew the lease of Diego Garcia to the US if it is able to wrest back sovereignty from the UK....

Correct Answer :   Larsen & Toubro (L&T)

The Defence Ministry has started the process for the procurement of 100 more K9-Vajra tracked self-propelled howitzers which are built in India by Larsen & Toubro (L&T) using technology transferred from South Korean defence major Hanwha Defense. 
 
“The Defence Ministry issued the Request For Proposal to L&T in November. Once they respond to it, the contract negotiations will begin,” a defence official confirmed. 
 
* At the height of tensions in eastern Ladakh in 2020, the Army deployed one regiment of K-9 Vajra tracked self-propelled howitzers there to augment its long-range fire power in the backdrop of a massive build-up of forces by China across the Line of Actual Control.

Buoyed by their performance, the Army is looking at eventually procuring 200 additional guns. The induction of Dhanush, K-9 Vajra and M777 Ultra Light Howitzers has enhanced the reach of artillery firepower on the northern borders.

* The K9 Vajra is a 155 mm, 52-calibre tracked self-propelled howitzer built by L&T with technology transferred from South Korean defence major Hanwha Defense based on its K9 Thunder.

* The 100th gun was delivered to the Army in February 2021, the contract for which was signed in May 2017. The contract also involved maintenance transfer of technology to an Army base workshop to support the howitzers throughout their operational life cycle.

* The K9 Vajra was mainly bought for use in deserts, but the standoff prompted them to be deployed in the mountains as well, officials had stated earlier.

* To ensure that these systems performed optimally in the extreme cold weather conditions of the mountains, the Army also procured winterisation kits for the regiment deployed. There are nine items including batteries, oils and lubricants which need to be insulated from extreme temperatures and don’t freeze at -20 degrees celsius, which the kits cater for...

Correct Answer :   Pralay

The decision by the Defence Ministry to procure indigenous short-range ballistic surface-to-surface (SRBM) missile Pralay, a conventional weapon that has become ready for induction in just seven years, gives Indian military the heft to its war-fighting capabilities.

A high-level meeting of the Defence Ministry cleared the acquisition of around 120 pralay missiles for the armed forces and their deployment along the borders.

India now permits the use of ballistic missiles in tactical roles, therefore the acquisition of these ballistic missiles is considered a significant development for the nation.
 
Significance Of This ballistic missile : The missile will be India’s first tactical quasi-ballistic missile and will give the armed forces the capability to hit enemy positions and key installations in actual battlefield areas. Pralay, along with the BrahMos supersonic cruise missile, will form the crux of India’s planned Rocket Force — a concept that was envisaged by former Chief of Defence Staff (CDS), the late General Bipin Rawat. Sources in the defence establishment made it clear that only conventional missiles would come under the planned Rocket Force as and when it’s ready, while nuclear weapons would continue to be under the ambit of the Strategic Forces Command.
 
About The Pralay missile project :

* The Pralay missile project was sanctioned in 2015 and is a derivative of the Prahaar missile programme, which was first tested in 2011.

* Sources said Pralay was formed through elements from multiple missile programmes that include the K-series of submarine-launched ballistic missiles and the ballistic defence shield programme.

* The canisterised Pralay missile, with a range of 150-500 kilometres, has been developed according to the specifications and requirement of the Army, which was looking to arm itself with a tactical conventional missile that could be used on the battlefield.

* Incidentally, both China and Pakistan have tactical ballistic missiles.

* Pralay is powered with a solid propellant rocket motor and multiple new technologies and, according to sources, accuracy is a highlight of this missile.

* It is capable of carrying a conventional warhead of about 350 kg to 700 kg, which gives it a deadly punitive capability.

* It can carry a high explosive preformed fragmentation warhead, penetration-cum-blast (PCB) and runaway denial penetration submunition (RDPS).

While BrahMos has high agility, stealth and even loitering capability, Pralay has the advantage of speed and countering it is a difficult task, even for modern air defence systems.

Why Pralay Is So deadly : 
* The Indian missile can be compared to China’s Dong Feng 12 and the Russian Iskander missile that has been used in the ongoing war with Ukraine.

* The US Army is in the process of increasing the range of a similar short-range ballistic missile called the Precision Strike Missile (PrSM). What makes Pralay deadly is that it is a quasi-ballistic weapon, which means that while it has a low trajectory and is largely ballistic, it can manoeuvre in flight. It has been designed to evade interceptor missiles..
