Operation Smiling Buddha, codenamed Pokhran-I, marks a key moment in Indian history and South Asia's geopolitics. On May 18, 1974, India detonated its first nuclear device in the dry sands of Rajasthan.
This pushed India into the group of nuclear-armed nations. This article explores the origins, execution, aftermath, and long-term effects of Operation Smiling Buddha.

The Genesis of India’s Nuclear Ambition
India’s path to nuclear power began after independence, mainly for peaceful aims like energy security and scientific growth.
However, the painful Sino-Indian war of 1962 and the 1965 war with Pakistan highlighted the need for strong national security.
These conflicts, along with China becoming a nuclear state in 1964, strengthened the case for a secret nuclear program.
In the late 1960s, India changed its nuclear program. Scientists at the Bhabha Atomic Research Centre (BARC) guided this shift.
Prime Minister Indira Gandhi was also important to this change. The program transitioned from being purely for research to focusing on strategic deterrence.
Operation Smiling Buddha: Concept, Planning, and Codenames
Why "Smiling Buddha"?
The operation received the name "Smiling Buddha" because this successful test occurred on Buddha Purnima, marking the birthday of Lord Buddha.
This choice sent a clear message. India wanted to showcase its test as a "peaceful nuclear explosion" to the world. It used Buddhist symbols of peace and enlightenment to emphasize its new status as a nuclear state.
Organizing in Secrecy
The operation's success depended on secrecy. Only a small group of high-ranking officials were aware of it. This group included Prime Minister Indira Gandhi, atomic energy commission head Dr. Homi Sethna, and BARC director Dr. Raja Ramanna.
A few selected scientists and military officers from DRDO were also informed. Even important cabinet ministers and military leaders were not told until a few days before the detonation.
Technical Preparation and Design
The device was a small, plutonium-based, implosion-type bomb. It weighed around 1,400 kg and measured 1.25 m in diameter.
The core material came from India's CIRUS reactor. This reactor had been used for peaceful research, with assistance from Canada and the U.S.
India's military also provided important support. They helped build underground shafts and made sure the test site was secure.
In total, around 75 leading scientists and engineers worked on the device and the test range. This took place from 1967 to 1974.
The Detonation at Pokhran
At exactly 8:05 AM on May 18, 1974, the firing button was pressed. Prime Minister Gandhi's order had been sent: "Dr. Ramanna, please go ahead. It will be good for the nation."
Scientist Pranab Rebatiranjan Dastidar was the one who pressed the button.
The device was buried 107 meters underground at the Pokhran test range. It detonated with a loud blast, creating a large crater and sending seismic waves through regional politics.
Official Description and Yield
The Indian government said the test was a "peaceful nuclear explosion" (PNE). They claimed it was for civilian purposes such as excavation and mining.
This explanation was accepted in India but faced doubt internationally. Indian officials initially reported a yield of up to 12 kilotons.
However, independent estimates suggested it was between 6 and 10 kilotons.
Domestic and International Reactions
Boost to National Morale
The success of Operation Smiling Buddha brought national pride. It showed that India had strong scientific abilities.
It also boosted Indira Gandhi’s political standing after the tough years following the 1971 war. The operation motivated a new generation of Indian scientists and technologists.
For the first time, India was recognized globally as a country that could handle the complex technology of nuclear weapons.
Diplomatic Fallout and Sanctions
The international response was quick and severe. The United States, Canada, and other countries that provide nuclear technology imposed embargoes.
They also halted all civilian nuclear cooperation with India.
A key outcome was the formation of the Nuclear Suppliers Group (NSG).
This group was established to stop further proliferation by enforcing strict controls on exports of nuclear technology.
Countries like Pakistan viewed the test as a direct threat. Prime Minister Zulfikar Ali Bhutto famously stated that Pakistan would never accept “Indian nuclear hegemony.”
This spurred Pakistan to develop its own nuclear program, igniting a nuclear arms race in South Asia.
Operation Smiling Buddha’s Significance
Strategic Deterrence
Operation Smiling Buddha gave India a reliable deterrent. This shifted the security dynamics of the region.
While India stated its intentions were peaceful, the world saw its ability to turn nuclear technology into weapons.
Technological Leap
The test showed what local efforts could accomplish. This happened even with strict secrecy and institutional pressures. The operation sparked future scientific progress.
It set the stage for the later Pokhran-II tests in 1998. In those tests, India announced that it was a complete nuclear weapons state.
Political and Diplomatic Outcomes
- Strengthening Self-reliance: The sanctions pushed India to become more self-sufficient in important technologies. This included nuclear, space, electronics, and defense. This shift changed the country's approach to innovation.
- Redefining Global Nuclear Order: India’s actions challenged the non-proliferation treaty (NPT). They argued that a country's security and its search for equality could be more important than choosing to hold back.
The Fallout and Legacy of Operation Smiling Buddha
Nuclear Isolation and Innovation
In the decades that followed, India experienced major technological isolation because of sanctions. This time, often referred to as 'nuclear apartheid,' made it difficult for the country to acquire uranium, reactors, and parts for other high-tech industries.
However, it also encouraged local innovation. This push for self-sufficiency eventually led to the resumption of civilian nuclear cooperation after the Indo-U.S. nuclear deal of 2008.
Strategic Stability and Minimum Deterrence
India did not conduct further tests for 24 years. This maintained its stated doctrine of minimum deterrence and no-first-use.
However, the test did set the stage for quick weaponization and the development of delivery systems. This ultimately led to the operationalization of India’s nuclear triad by the 21st century.
Changing the South Asian Security Environment
Pakistan's pursuit of nuclear capability was a direct response. This led to a delicate nuclear balance in the region.
It became evident in 1998 when both India and Pakistan conducted nuclear tests in quick succession.
The proximity of these two nuclear-armed nations remains a flashpoint in current security discussions.
Pokhran Then and Now
Today, Pokhran is more than just a place. It represents India’s determination and technological progress, as well as its changing role in the world.
The legacy of Operation Smiling Buddha still remains. It shows in India’s active participation in nuclear disarmament talks, its advancements in civilian nuclear technology, and ongoing conversations about nuclear ethics and global governance.
Key Takeaways of Operation Smiling Buddha
- India’s first nuclear test occurred on May 18, 1974, under strict secrecy in Pokhran, Rajasthan.
- The test propelled India into the group of nuclear-capable states, sixth after the US, USSR, UK, France, and China.
- It led to significant global reactions, notably the formation of the NSG and international sanctions, while also sparking local innovation.
- Operation Smiling Buddha’s legacy is profound; it changed India’s security strategy, redefined the global nuclear order, and remains a key part of the nation’s strategic stance.
Operation Smiling Buddha was more than a single test. It marked a turning point that changed India’s future.
The operation signaled a new era in the country's pursuit of security, knowledge, and global status.
Today, India still tries to maintain its commitment to peace while facing the challenges of a troubled region. The lessons of Pokhran remain important.
After the 1974 tests, explosions of five nuclear devices – three on May 11 and two on May 13, 1998 – were conducted by India, again at the Pokhran test range.
Codenamed ‘Operation Shakti’, the tests were carried out under former Prime Minister Atal Bihari Vajpayee’s term. India conducted Pokhran-II tests, a series of five nuclear explosions, in May 1998 at the Indian Army’s Pokhran Test Range in Rajasthan.
National Technology Day is observed every year on May 11 as a reminder of the anniversary of the Pokhran-II tests.
