Arihant, Arighaat, Aridhaman: Inside India’s growing nuclear submarine triad against China, Pakistan
“歼敌者”“觅敌者”“御敌者”：印度针对中巴、不断壮大的海基核三位一体内幕
NEW DELHI: India's underwater deterrence is set to enter a decisive new phase with the induction of INS Aridhaman, the third Arihant-class nuclear-powered ballistic missile submarine, by May 2026. Once INS Aridhaman joins INS Arihant and INS Arighat, India will operate three indigenously built SSBNs under the Strategic Forces Command.
At a time when China is expanding its nuclear and conventional submarine footprint across the Indo-Pacific and Pakistan is inducting advanced Chinese-origin boats with air-independent propulsion, New Delhi’s strategic planners are steadily reinforcing the most secure and resilient leg of the nuclear triad — the sea. Larger, quieter and armed with longer-range K-4 submarine-launched ballistic missiles, Aridhaman strengthens India’s second-strike capability and moves it closer to continuous at-sea deterrence.
With Aridhaman joining INS Arihant and INS Arighaat, India now operates three indigenously built SSBNs under the Strategic Forces Command. This marks not just an incremental addition to naval inventory but a structural shift in India’s strategic posture.
As Beiing fields one of the world's largest submarine fleets and Islamabad bolsters its underwater arsenal, India's expanding SSBN force ensures credible minimum deterrence along with a devastating second-strike capability —stealthy, nuke-proof, and unstoppable — from the deepest depths of the Indian Ocean.
新德里：随着第三艘“歼敌者”级核动力弹道导弹潜艇“御敌者”号在2026年5月前服役，印度的水下核威慑将进入决定性的新阶段。一旦“御敌者”号与“歼敌者”号、“觅敌者”号汇合，印度将在战略部队司令部下辖部署三艘国产战略核潜艇。
当前，中国正在印太地区扩大核动力与常规潜艇部署，巴基斯坦也在列装源自中国的先进不依赖空气推进潜艇，印度战略规划层正稳步强化核三位一体中最安全、生存能力最强的一环——海基力量。“御敌者”号吨位更大、静音性更好，并搭载射程更远的K-4潜射弹道导弹，大幅强化印度的二次核打击能力，让印度更接近实现不间断的海上核威慑。
随着“御敌者”号加入“歼敌者”号与“觅敌者”号，印度目前已在战略部队司令部下运作三艘国产战略核潜艇。这不仅是海军装备数量的增加，更是印度战略态势的结构性转变。
在中国拥有全球规模最大潜艇部队之一、巴基斯坦强化水下武库的背景下，印度不断壮大的战略核潜艇部队，确保了可靠的最低核威慑，同时具备从印度洋深处发起毁灭性二次打击的能力——隐蔽、抗核打击、难以拦截。
INS Arihant: The pioneer of India’s sea-based deterrence
Commissioned in August 2016, INS Arihant was the culmination of decades of classified work under the Advanced Technology Vessel programme. Built at the Shipbuilding Centre in Visakhapatnam, Arihant displaced around 6,000 tonnes and was powered by an 83 MW Compact Light Water Reactor developed with significant indigenous input.
Measuring roughly 111.6 metres in length, Arihant introduced India to the elite group of nations operating nuclear-powered ballistic missile submarines. Its propulsion allows virtually unlimited range, with endurance limited primarily by crew supplies. Capable of speeds of around 24 knots submerged, it is designed for extended stealth patrols in the Indian Ocean Region.
In terms of armament, Arihant carries four vertical launch system tubes. These can be configured to deploy up to 12 K-15 Sagarika submarine-launched ballistic missiles with a range of approxmately 750 km, or four K-4 missiles with a reach of around 3,500 km. It also features six 533 mm torpedo tubes for defensive and conventional strike roles.
The most important milestone came in 2018, when Arihant completed its first deterrence patrol. That patrol marked the operationalisation of India’s sea-based nuclear deterrent, completing the triad alongside land-based missiles and air-delivered systems. For Indian planners, Arihant represented assured retaliation — the guarantee that even in the worst-case scenario, India would retain a secure response capability beneath the sea.
歼敌者号核潜艇：印度海基核威慑的先驱
2016年8月正式服役的歼敌者号，是印度先进技术舰船项目历经数十年秘密研发的最终成果。该潜艇在维沙卡帕特南造船中心建造，排水量约6000吨，由一座83兆瓦紧凑型轻水反应堆提供动力，核心技术高度国产化。
歼敌者号全长约111.6米，让印度跻身拥有核动力弹道导弹潜艇的精英国家行列。其核动力系统几乎拥有无限续航力，自持力主要受艇员物资补给限制。水下航速可达24节左右，专门用于在印度洋区域执行长期隐蔽巡逻任务。
武器配置方面，歼敌者号拥有4座垂直发射系统，可搭载12枚射程约750公里的K-15萨加里卡潜射弹道导弹，或4枚射程约3500公里的K-4导弹。艇上还配备6具533毫米鱼雷发射管，用于自卫与常规打击。
该潜艇最重要的里程碑是2018年完成首次战略威慑巡逻，标志着印度海基核威慑正式形成战斗力，与陆基导弹、空基打击系统共同构成完整的核三位一体。对印度战略规划者而言，歼敌者号意味着可靠的二次核反击能力——即便在最恶劣情况下，印度仍能在水下保留安全的反击手段。

with no hegemonic plans & aggressive intentions INDIA is projecting its military might. O.P SINDOOR demonstrated convincingly to all its adversaries. INDIANS are ecstatic about the rapid INDIA's Emerging as a global POWER.
印度没有霸权图谋，也没有侵略意图，只是在展示自身军事实力。我们去年发动的辛杜尔行动已经有力震慑了所有对手。印度正快速崛起为世界强国，印度民众都为此欣喜不已。

Has this TRIAD been TRIAD been TRIED against China or Pakistan to justify the comparison with Navies of the two countries. If you have a powerful Navy say "I have a powerful Navy" Tarzan never said to Jane " Me Tarzan more handsome than Nazrat" He said conclusively "I Tarzan You my Jane"
这套核三位一体真的和中国、巴基斯坦实战过吗？凭什么和这两国海军相提并论？自己海军强，就直接说“我海军很强”。泰山从不会对简说“我比纳兹拉特帅”，他只会明确说“我是泰山，你是我的简”。

Instead of manufacturing 6 AIP subs , India should construct 6 Nuclear SSBN ( almost at similar cost ).
印度与其造6艘AIP常规潜艇，不如造6艘战略核潜艇，成本其实差不多。

Impressive !!!! Keep it up India and get on par to all the other countries western countries ! These submarines will bring world peace LOL
太厉害了！印度继续加油，早日追上西方国家！这些潜艇会带来世界和平，哈哈哈。

why this types of details are published? I am sure this is know fact to our enemy this is not a type of chest thum to be done.
为什么要公布这些细节？敌人肯定早就知道了，这不是用来自我炫耀的。

ATV project has done far better than our fighter aircraft Tejas MK1a, MK2 and AMCA program because in fighter aircraft program the oversight is scattered with different agencies pushing blame on each other for delays.
先进技术舰船项目比光辉MK1a、MK2和AMCA战机项目靠谱多了。战机项目监管混乱，出了延误各部门只会互相甩锅。

Hyena...China..is the real..enemy..
中国才是我们印度真正的敌人。

We will be the top nation of this planet by the end of this century and our boundaries will extend to where they should be but we will not bully any other nation because that's what's taught to us by our ancestors who were far-2 greater than us. Vandematam
本世纪末印度一定会成为世界第一强国，收复本该属于我们的领土。但我们不会欺负其他国家的，这是祖先教给我们的。祖国万岁。
