The sea component of Pakistan’s nuclear force consists of the Babur class of cruise missiles. The latest version, Babur-2, looks like most modern cruise missiles, with a bullet-like shape, a cluster of four tiny tail wings and two stubby main wings, all powered by a turbofan or turbojet engine. The cruise missile has a range of 434 miles. Instead of GPS guidance, which could be disabled regionally by the U.S. government, Babur-2 uses older Terrain Contour Matching (TERCOM) and Digital Scene Matching and Area Co-relation (DSMAC) navigation technology. Babur-2 is deployed on both land and at sea on ships, where they would be more difficult to neutralize. A submarine-launched version, Babur-3, was tested in January and would be the most survivable of all Pakistani nuclear delivery systems.
Sandwiched between Iran, China, India and Afghanistan, Pakistan lives in a complicated neighborhood with a variety of security issues. One of the nine known states known to have nuclear weapons, Pakistan’s nuclear arsenal and doctrine are continually evolving to match perceived threats. A nuclear power for decades, Pakistan is now attempting to construct a nuclear triad of its own, making its nuclear arsenal resilient and capable of devastating retaliatory strikes.
Pakistan’s nuclear program goes back to the 1950s, during the early days of its rivalry with India. President Zulfikar Ali Bhutto famously said in 1965, “If India builds the bomb, we will eat grass or leaves, even go hungry, but we will get one of our own.”
The program became a higher priority after the country’s 1971 defeat at the hands of India, which caused East Pakistan to break away and become Bangladesh. Experts believe the humiliating loss of territory, much more than reports that India was pursuing nuclear weapons, accelerated the Pakistani nuclear program. India tested its first bomb, codenamed “Smiling Buddha,” in May 1974, putting the subcontinent on the road to nuclearization.

Pakistan began the process of accumulating the necessary fuel for nuclear weapons, enriched uranium and plutonium. The country was particularly helped by one A. Q. Khan, a metallurgist working in the West who returned to his home country in 1975 with centrifuge designs and business contacts necessary to begin the enrichment process. Pakistan’s program was assisted by European countries and a clandestine equipment-acquisition program designed to do an end run on nonproliferation efforts. Outside countries eventually dropped out as the true purpose of the program became clear, but the clandestine effort continued.

Exactly when Pakistan had completed its first nuclear device is murky. Former president Benazir Bhutto, Zulfikar Bhutto’s daughter, claimed that her father told her the first device was ready by 1977. A member of the Pakistan Atomic Energy Commission said design of the bomb was completed in 1978 and the bomb was “cold tested”—stopping short of an actual explosion—in 1983.
Benazir Bhutto later claimed that Pakistan’s bombs were stored disassembled until 1998, when India tested six bombs in a span of three days. Nearly three weeks later, Pakistan conducted a similar rapid-fire testing schedule, setting off five bombs in a single day and a sixth bomb three days later. The first device, estimated at twenty-five to thirty kilotons, may have been a boosted uranium device. The second was estimated at twelve kilotons, and the next three as sub-kiloton devices.
The sixth and final device appears to have also been a twelve-kiloton bomb that was detonated at a different testing range; a U.S. Air Force “Constant Phoenix” nuclear-detection aircraft reportedly detected plutonium afterward. Since Pakistan had been working on a uranium bomb and North Korea—which shared or purchased research with Pakistan through the A. Q. Khan network—had been working on a uranium bomb, some outside observers concluded the sixth test was actually a North Korean test, detonated elsewhere to conceal North Korea’s involvement although. There is no consensus on this conclusion.
